    Why make a traybake?

    So why a Biscoff tray bake in particular (or biscoff sheet cake, for my US readers)? Well, I do have a similar Biscoff cake in the traditional layer cake form, and it's a beauty, but I love the convenience of a tray bake.

    It's easy to cut into attractive squares of whatever size works best for you, and it's easily transported in the tin it's baked in if you want to take it to share at gatherings or events. The neat portions also lend themselves beautifully to be packed as delightful treats to share with friends, family, or coworkers.

    How easy is this Biscoff traybake to make?

    With its impressive appearance, you might think this tray bake requires intricate preparation. However, fear not! This recipe is genuinely easy to make for bakers of all levels. I've made sure to include detailed step-by-step instructions below, accompanied by a photograph for every stage to help make sure your baking journey is smooth and enjoyable.

    So how is this divine Biscoff traybake made? It starts with the irresistible Biscoff-flavoured sponge, which is made in a single bowl.

    You'll simply beat butter and brown sugar together, then whisk in eggs, milk and Biscoff Smooth Spread before folding in self raising flour and a pinch of salt to give you have a gorgeously flavourful cake batter.

    You'll then spread the batter in a lined, medium roasting tin and bake to risen, golden, aromatic perfection.

    Complementing the exquisite sponge is the luscious Biscoff buttercream. Creamy and velvety, this frosting is rich with the signature taste of Biscoff spread, adding an extra layer of indulgence to every square of this tray bake.

    To make the frosting, you'll simply measure butter, icing sugar, salt, Biscoff spread and milk into a large bowl and whisk until pale and creamy.

    Finally, you'll pipe the Biscoff buttercream in rosettes on top of the cooled sponge and top with crumbled Biscoff cookies and a drizzle of Biscoff spread for extra wow factor. You'll get such a beautiful result, you'll want to show it off straight away!

    Are you ready to make this easy, enchanting and extraordinary Lotus Biscoff traybake?
