This irresistible Lotus Biscoff birthday cake is a dreamy delight for Biscoff lovers, with layers of tender Biscoff sponge and creamy Biscoff buttercream.
This exquisite cake is truly a celebration of the beloved Lotus Biscoff cookies, meaning it's perfect for anyone who adores the delightful combination of cinnamon and caramel.
And the best part? Despite its gourmet appeal, this Lotus Biscoff birthday cake is surprisingly easy to make, whether you're a seasoned baker or enthusiastic beginner. As with all my recipes, below you'll find detailed step-by-step instructions, accompanied by clear pictures of every stage, so whether you're baking for a birthday celebration or simply to indulge your sweet cravings, this cake will come together effortlessly, first time.
At the heart of this delectable Biscoff birthday cake lies a moist and fluffy Biscoff-flavoured sponge. Imagine the comforting aroma of freshly baked Biscoff cookies wafting through your kitchen - that's what's encapsulated in every tender crumb of this sponge.
The sponge is made with simple ingredients - butter, sugar, eggs, flour, baking powder and a pinch of salt - plus a crucial ingredient, Lotus Biscoff Smooth Spread, which ensures plenty of unmistakable Biscoff flavour with each mouthful. The delicate balance of sweetness and warmth will leave you yearning for just one more slice.
To bring the sponge together, you'll simply cream butter and light brown sugar together, whisk in eggs, milk, vanilla and Biscoff smooth spread, and then fold in flour along with a pinch of baking powder and a pinch of salt.
You'll then pile the batter into three lined baking tins and bake until they're perfectly risen and tender and your kitchen smells amazing!
To elevate this Biscoff birthday cake to heavenly heights, you'll fill the layers of sponge with a velvety Biscoff buttercream that perfectly complements the sponge. Smooth, creamy, and generously laced with the distinctive taste of Biscoff spread, this frosting is a true delight that will have you licking the bowl, and it pairs with the sponge to create a taste that have you swooning.
Making the buttercream is a very simple process. You'll simply place butter, powdered sugar (icing sugar), milk, Biscoff smooth spread and a pinch of salt in a bowl and whisk together until you have a smooth buttercream frosting.
To assemble, I like to pipe rosettes of frosting between each layer, and on top of the final cake, but if you'd rather just spread with a palette knife, you'll still get a dreamily attractive result.
To finish, you'll crumble some Lotus Biscoff cookies over the top of your cake, drizzle it with Lotus Biscoff spread and it's ready to serve!
So, whether you're surprising a Biscoff enthusiast on their special day or treating yourself to a sumptuous dessert, it's time to start making this Lotus Biscoff birthday cake.
