Put your Biscoff spread in a heatproof bowl and pop it in the microwave for 10 seconds. It shouldn’t need any more than this, it is just to make the Biscoff lovely and soft. Pop the biscoff into a piping bag and leave to one side.
Place your first cake on your serving plate and pipe the buttercream on top. Smooth using a spatula, don’t worry is any of the buttercream splodges out the side. Drizzle over your biscoff spread. Repeat until your cake is stacked.
Pipe the buttercream onto the top of the cake, again don’t worry if it goes over the edges
Using your cake smoother smooth around the sides of the cake. Don’t worry if you can see the cake through the buttercream, this is just the crumb coat. We will cover the cake soon.
If there are any gaps, pipe buttercream into the gaps and then smooth again using your cake smoother.
Once there are no gaps in your cake pop it into the fridge until the buttercream has hardened.
Once the buttercream has hardened, pipe the remaining buttercream around the sides of the cake.
Using your smoother, smooth around the sides, if there are any gaps fill these with the buttercream and continue to smooth around the sides until the cake is smooth. You will most likely take some of the buttercream off the cake if you do pop this back into your bowl and we will use this for the swirls on top of the cake.
Using a spatula smooth any buttercream into the top of the cake so you have nice sharp edges.
Using your Biscoff spread go around the edge of the cake and encourage it to drip. I do this by holding the piping bag or squeeze bottle ever so slightly away from the cake. If you have any leftover Biscoff pour it onto the top of the cake and smooth.
Pop the cake into the fridge for half an hour to allow the Biscoff to set. If you don’t your buttercream will just slide off.
Put your leftover buttercream into a piping bag and pipe swirls onto the top of the cake
Decorate with your Biscoff biscuits. I decorated by crushing up some biscuits and placing them randomly around the bottom of the cake and then decorated the top with whole biscuits. This is completley optional you can decoare it in any way you want.
