These Biscoff Cupcakes are the ultimate indulgence - soft, fluffy sponge with a hint of cinnamon, filled with smooth Biscoff spread, and topped with the dreamiest caramel buttercream swirl.
Preheat your oven to 170°C (fan) / 190°C / 375°F. Line a 12-hole muffin tin with cupcake cases.
In the bowl of a stand mixer, or in a large bowl if mixing by hand, beat the butter and sugar together until light and fluffy. Add the eggs one at a time, mixing well after each. Stir in the vanilla extract.
Sift in the flour, baking powder, and cinnamon. Fold everything together gently, then mix in the milk until the batter is smooth.
Divide the batter evenly between the cupcake cases, filling each about ¾ full. Bake for 20-22 minutes, or until a skewer inserted into the centre comes out clean. Let them cool completely.
Once cooled, use a cupcake corer or small knife to cut out the centre of each cupcake. Fill each hole with a spoonful of Biscoff spread.
To make your buttercream, beat the butter until pale and creamy, then gradually add the sifted icing sugar. Mix in the caramel sauce and beat until smooth and fluffy. Add a splash of milk if needed to loosen the consistency.
Pipe a swirl of caramel buttercream onto each cupcake. If you're feeling fancy, drizzle over some extra caramel sauce, then top with a Biscoff biscuit. Sprinkle over some crushed biscuits for extra crunch.
Enjoy! These cupcakes are best enjoyed fresh but will keep in an airtight container for up to 3 days.
