Creamy vanilla buttercream, flecked with crunchy Oreo pieces. This cookies and cream cake filling is the perfect way to take a layer cake to the next level.

And despite its bakery-quality appearance, it’s actually exceptionally easy to make.
The first step in making these cookies and cream cake filling is to whip up a basic vanilla buttercream.
For this, you will beat butter on its own until pale and creamy. Beating the butter on its own helps to soften it but also incorporates some all important air that will help ensure a light and creamy end result
Next, you'll add sifted icing sugar, a dash of vanilla extract and a splash of milk before whisking to a smooth, cool frosting.
Finally, you fold in crushed Oreos to produce a gorgeous, grey, flecked buttercream.
It’s looks almost stone like in appearance and is very, very tasty with an unmistakable Oreo flavour that makes it perfect for complementing all manner of cakes, sandwich cookies and more.
Read on for the full recipe with detailed instructions and a helpful photograph for every step. And if you have any questions, just leave me a comment. Enjoy!
Ingredients

- 250 g (2 sticks + 2 tsp) salted butter softened
- 1½ tsp vanilla extract
- 60 ml (½ cup) whole milk
