Oreo Brownies

The perfect blend of two iconic American treats, these Oreo Brownies are sure to become your new favourite dessert!

With a classic chocolate brownie batter and full-sized Oreos in every bite, how could it not?

Brownies and Oreos are a perfect combination. The fudgy, rich brownie is perfectly complemented by the crisp chocolate Oreo cookie with its trademark creamy filling.

In fact, brownies and Oreos make such a popular combination that in 2015, Nabisco launched Brownie Batter Oreo cookies (Or "Choc'O Brownie flavour Oreos") as a new variety!

So if you want to make this recipe a step further, you could go meta and use Brownie Batter Oreos in this Oreo Brownies recipe. Mind. Blown.

To make your Oreo Brownies, you'll melt some chocolate and butter together, then whisk in sugar, followed by eggs, vanilla and then flour to make a lovely, chocolatey batter.

Next, you'll pour half of your batter into the greased baking tray and drizzle on a sneaky ingredient that takes these brownies to the next level and beyond: cookies and cream spread!

You'll then top the batter with Oreos and cover with the remaining batter before drizzling with more spread. Finally, you'll top the brownies with broken Oreo pieces.

To cook your brownies, you'll pop them in the oven for 30 minutes until they're just set. Remember, brownies aren't like cakes; you want them sticky and fudgy, not baked to a crumb consistency like a sponge.

If all this is giving you serious Oreo brownie cravings, read on.

I've included detailed step-by-step instructions below, along with a photo for every stage. Enjoy!

Instructions

Make the brownie batter

Preheat the oven to 180C (160C fan).

Grease and line your tin.

Put the dark chocolate and butter in a large microwave-safe bowl.

Microwave in 30-second bursts, stirring between each burst until melted. Avoid overcooking as this can negatively affect the chocolate.

Add the caster sugar.

Stir through with a manual whisk - I say stir as you don’t want to add air but a whisk is still the best tool as it distributes everything quickly.

Add the eggs and vanilla.

Stir with the whisk again.

Put the flour through a sieve into the bowl. 

Stir to combine.

Assemble the brownie

Place the cookies and cream spread in a bowl and microwave for 15-30 seconds until loosened.

Pour half of the brownie batter into your prepared tin and level off.

Drizzle half the spread over the brownie batter. 

Top with three quarters of the Oreo cookies (reserve about 8 cookies or 60g).

Pour the remaining brownie batter on top and level off.

Drizzle with the remaining spread and swirl a little with the handle end of a spoon.

Top with the remaining broken Oreo cookies.

Bake for 30 minutes. You can test if it's baked by pushing a skewer into the centre. If just right, you'll see sticky crumbs.

Place the brownie in its tin on a wire rack to cool completely. I like to then chill mine overnight to get them nice and firm for slicing.

Once completely cooled, transfer the brownie slab to a board and trim the edges, then cut into 12 equally sized Oreo Brownies squares in a 3x4 pattern.

Enjoy!

Pointers, tricks and troubleshooting tips for the perfect Oreo Brownies

Are Oreo Brownies easy to make?

Oreo brownies are deceptively simple to make and only require a few ingredients you probably already have in your pantry. Oreos, cookie spread, butter, sugar, eggs, and flour are all you need for these delicious brownies.

The recipe has plenty of detailed instructions and step-by-step pictures to help you get picture perfect results. There are a few key steps to follow for the best results:

• First, your Oreos need to be finely crushed to be evenly distributed throughout the batter.
• Be sure not to overmix the batter or your brownies will be cakey instead of fudgy.
• Finally, don't forget to top your brownies with Oreos before baking for an extra Oreo kick!

With these pointers in mind, you'll be able to make the perfect Oreo brownies every time. Enjoy!

Will I need any special equipment to make Oreo Brownies?

You won't need special equipment to make your Oreo brownies. All you need is some weighing scales, measuring spoons, utensils, a cutting board, a bowl, a saucepan and a baking tray lined with baking paper.

There's always a full list of suggested equipment on the recipe card below my recipes if you're in doubt. I always include links to example products to show exactly what I used to make each recipe.

What is cookies and cream spread?

Cookies and cream spread is a type of frosting or filling made from Oreos or black and white style cookies. It is typically used to fill and frost cakes or brownies and can also be eaten by itself as a dessert.

In the UK, some supermarkets sell a version marketed for spreading on toast. That kind is fine to use too.

You'll usually find cookies and cream spread on the same aisle as jams and honey, though it's sometimes stored in the baking aisle.

How can I tell if eggs have gone off?

You'll usually know when an egg is spoiled as soon as you crack it open. The unmistakable smell of a rotten egg is something that stays with you!

You should never eat an egg that looks, smells, feels or tastes odd in any way. So if your egg has any discolouration, odd appearance, or a strange or foul odour, it is most likely rotten.

If your egg has spoiled, you should immediately throw it away and thoroughly wash any pots and utensils that have come into contact with it.

Even if your egg isn't spoiled, you should ensure it is as fresh as possible. It's always best to use fresh ingredients when baking, especially eggs. It's essential to use fresh eggs, as they can behave differently in recipes as they get older and their quality declines. 

How can I tell if my butter has gone off?

The most common signs that your butter has spoiled are if it smells sour or has a fizzy taste/mouthfeel.

Another indication of spoilage is when the butter becomes too soft and difficult to work with or when it separates into solids and liquids. The first sign is if the butter develops a layer of condensation or 'sweat' (eurgh!).

Some visible signs that butter is very spoiled are that it may start to develop a greenish-white film or mould on the surface. But by this point, you should already know/smell that it's time to discard the butter!

Are Oreo Brownies suitable for vegetarians?

These Oreo Brownies should be suitable for vegetarians as they do not contain any meat, poultry or fish. However, please check the ingredients list on the Oreo cookies and cream spread to double-check that these products are vegetarian-friendly.

Animal-derived products can be used to thicken, colour or flavour sweet and savoury food, so it sneaks into the most surprising ingredients!

So always make sure that you double-check all of your ingredient labels to ensure that they are vegetarian. Also, don't forget to check anything extra you intend to serve with your Oreo Brownies.

Are Oreo Brownies suitable for vegans?

These Oreo Brownies aren't vegan, as they contain dairy and egg. You could make a vegan version using alternatives like plant-based butter, egg replacement powder, vegan chocolate, and Oreos.

However, I'm not so sure this recipe method would work for a vegan recipe, as the eggs are key to getting the texture and consistency in the brownie batter.

Are Oreo Brownies gluten-free?

Oreo Brownies are not gluten-free as they contain wheat flour. You could make a gluten-free version using gluten-free all-purpose or almond flour.

I regularly use Doves Farm gluten-free flour, and it has worked well in previous brownie recipes. So I would highly recommend giving them a try!

I haven't tried making this recipe with either of those ingredients, so I'm not sure how well it would work.

Double-check all of your ingredient labels to make sure that they are gluten-free. Don't forget to check anything extra you intend to serve with your Oreo Brownies.

Are Oreo Brownies keto-friendly?

Oreo Brownies are not keto-friendly as they contain wheat flour, sugar, and Oreos. You could make a keto-friendly version by using almond flour, erythritol, and a low-carbohydrate Oreo alternative.

I haven't tried making this recipe with those ingredients, so I'm not sure how well it would work. Double-check all of your ingredient labels to make sure they are keto-friendly

Don't forget to check anything extra you intend to serve with your Oreo Brownies.

Are Oreo Brownies suitable for those on a FODMAP diet?

Oreo brownies are unsuitable for those following the FODMAP diet as they contain wheat flour, Oreos, and butter. Sorry!

Are Oreo Brownies healthy?

Like most Oreo recipes, Oreo Brownies are not particularly healthy. They do contain some good ingredients like eggs and butter. However, they are also high in sugar and calories. So they should be enjoyed in moderation!

Are Oreo Brownies safe to eat while pregnant?

Oreo Brownies are generally safe to eat while pregnant. However, you should double-check that your ingredients do not contain any unpasteurized dairy.

Pregnant people should avoid unpasteurized dairy as it may contain harmful bacteria that could lead to food poisoning. Most supermarket dairy is pasteurised, but if you buy it from a farm or independent supplier, you should confirm it is pasteurised.

Oreo Brownies are also high in sugar, so pregnant people should consume them in moderation as pregnancy can make you more sensitive to changes in blood sugar.

Make sure that all your ingredients are in good condition and that you prepare this meal safely and hygienically.

Is Oreo Brownies suitable for babies and toddlers?

These brownies are unsuitable for babies or young children, as they contain a lot of sugar.

The NHS has some fantastic resources on their website on what to feed babies and young children.

What goes well with Oreo Brownies?

There are lots of things that go well with Oreo Brownies! Here are some of our favourites:

• Vanilla ice cream
• Chocolate sauce
• Even more Oreo cookies crumbled over the top
• Whipped cream or chantilly cream
• Or for something lighter, creme fraiche or whipped yoghurt.
• Fruit (strawberries, raspberries, etc.) or a fruit coulis

Can I add extra chocolate to this recipe?

Yes, you can! If you want to make your Oreo Brownies extra chocolatey, you could:

• Add some melted chocolate to the brownie batter before you add the Oreos.
• Use a different type of Oreo cookie. There are loads of different flavours available now!
• Sprinkle some chopped chocolate over the top of the brownies before you bake them.

I haven't tried any of these ideas myself, so I can't say for sure how well they would work. But they should all be delicious!

How should I store Oreo Brownies?

Oreo Brownies will last for 4-7 days in an airtight container at room temperature. You can also keep them in the fridge, but bear in mind it will make them even fudgier - not a bad thing!

How long will Oreo Brownies keep?

Oreo Brownies will last for 4-7 days in an airtight container at room temperature or in the fridge.

Can I leave Oreo Brownies out on the counter?

Oreo Brownies are best stored in an airtight container at room temperature. They will be fine for a few hours if you leave them out on the counter. But after that, they will start to dry out and won't be as nice to eat. Plus, it makes them vulnerable to contaminants and bugs, so keeping them in a container is best.

Can I make Oreo Brownies ahead?

Yes, these Oreo Brownies are perfect for making ahead! It's best to make them no more than a couple of days ahead, but they'll last in an airtight container for 4-7 days.

Can I keep Oreo Brownies in the refrigerator?

Oreo Brownies will last for 4-7 days in an airtight container at room temperature or in the fridge.

Can I freeze Oreo Brownies?

Oreo Brownies freeze really well! Just ensure they're well wrapped and will last for up to 3 months in the freezer.

Wrapping your brownies tightly will help prevent freezer burn. Freezer burn is when ice crystals form on the surface of food through a sort of cold air evaporation process. It makes frozen and defrosted food dry and crumbly, so preventing it is key to keeping your brownies as delicious as possible.

What is the best way to defrost Oreo Brownies?

Oreo Brownies can be defrosted overnight in the fridge or for a few hours at room temperature. Once they're thawed, they'll keep in an airtight container at room temperature for 4-7 days.

If you try to defrost Oreo Brownies too quickly (in the microwave, for example), they can end up dry, crumbly and not very nice to eat. So it's best to defrost them slowly and patiently!

Can I make Oreo Brownies in a stand mixer such as a KitchenAid or Kenwood Mixer?

Yes, you can make Oreo Brownies in a stand mixer. Just follow the recipe as normal, adding all of the ingredients to the bowl of your mixer and mixing until everything is combined. Make sure you scrape down the sides of the bowl to ensure all of your ingredients are fully incorporated.

If you're using a KitchenAid or similar mixer, use the paddle attachment on a low speed. If you're using a Kenwood mixer, use the beater attachment at a low speed.

Don't overmix the batter - you don't want to end up with tough brownies! Just mix until everything is combined and there are no more streaks of flour. Then fold in the Oreos by hand.

Can I make Oreo Brownies with a food processor?

A food processor would be too powerful for mixing your brownie batter, so it's best to mix it by hand or in a stand mixer. If you want to use a food processor, you could blitz the Oreos into crumbs and then fold them into the batter by hand.

How can I make sure my Oreo Brownies turn out perfectly?

Here are a few pointers to help you make perfect Oreo Brownies:

• Use good quality chocolate. This will make a big difference to the flavour and texture of your brownies. Cheap chocolate can be waxy and not very nice to eat.
• Make sure you measure out your ingredients accurately. Baking is a science, so ensuring your ingredients are correctly measured is crucial to getting the right results.
• Don't overmix the batter - this will make your brownies tough. Just mix until everything is combined and there are no more streaks of flour. Then fold in the Oreos by hand.
• Bake the brownies until they're just set. They will continue to cook a little as they cool, so you don't want to overbake them.
• Allow the brownies to cool completely before cutting them into squares. This will help prevent them from crumbling or breaking apart.

Why did my Oreo Brownies turn out dry/crumbly?

There are a few possible reasons why your Oreo Brownies might have turned out dry or crumbly:

• You overbaked them. Oreo Brownies should be set in the middle - they will continue to cook a little as they cool. If you bake them until they're cooked all the way through, they will be dry and crumbly.
• You overmixed the batter. Mixing the batter too much will make your brownies tough. Just mix until everything is combined and there are no more streaks of flour. Then fold in the Oreos by hand.
• Your ingredients weren't correctly measured. Baking is a science, so ensuring your ingredients are correctly measured is crucial to getting the right results.
• You used cheap or inferior quality chocolate. This can make a big difference to the flavour and texture of your brownies. Use good quality chocolate for the best results.

Why did my Oreo Brownies turn out wet/soft/dense?

There are a few possible reasons why your Oreo Brownies might have turned out wet or soft:

• You underbaked them. Oreo Brownies should be just set in the middle - they will continue to cook a little as they cool. If you take them out of the oven too early, they will be wet and dense.
• Your ingredients weren't correctly measured. If you added too much fat or liquid to the batter, the brownies will turn out very wet.

Why didn’t my Oreo Brownies rise?

Your brownies shouldn't really rise. They might slightly 'puff up', but in general, they will be a similar size to the uncooked batter in the tin.

How can I add/change the flavours in these Oreo Brownies?

There are lots of ways you can change the flavours in Oreo Brownies. Here are a few ideas:

• Add a handful of chocolate chips to the batter for extra chocolatey brownies.
• Fold in some chopped nuts, such as walnuts or pecans, for a crunchy twist.
• Swap the Oreos for other cookies, such as graham crackers or gingerbread cookies.
• Add a tablespoon or two of instant coffee powder to the batter for mocha brownies.
• For a fruity twist, stir some dried fruit, such as raisins or cranberries.

Where is the origin of Oreo Brownies?

There is no one specific origin of Oreo Brownies. It is thought that they were created in the United States, possibly inspired by Oreo Cookies which were first introduced in 1912. Oreo Brownies became popular in the 1970s and have been a favourite ever since!
