Ingredients

For the sponge

  • 140 g soft margarine or butter if using butter, make sure it's soft and at room temperature
  • 120 g soft light brown sugar
  • 240 g Lotus Biscoff spread
  • 120 g self-raising flour
  • 120 g Lotus Biscoff biscuits c. 16 biscuits
  • 4 medium eggs
  • 1 tsp baking powder

For the buttercream

  • 125 g butter soft and at room temperature
  • 250 g Lotus Biscoff spread
  • 185 g icing sugar
  • A little milk

To decorate

  • 6 Lotus Biscoff biscuits I only add 6 biscuits as otherwise I think the cake looks overcrowded. However, I keep an extra 6 to one side to give to anyone missing a biscuit on their slice.

Instructions

Make the Biscoff sponge

  • Pre-heat your oven to 160°C/140°C fan.
  • Line 2x20cm sandwich tins with greaseproof paper or reusble baking liners.
  • Crush the Biscoff biscuits (120g) until fine - I use a pestle and mortar, but you could also use a food processer or place the biscuits in a bag and hit them with a rolling pin.
  • Place all of the cake ingredients into a large bowl (crushed Biscoff biscuits, 140g soft margarine, 120g soft light brown sugar, 240g Biscoff spread, 120g self-raising flour, 4 medium eggs and 1 tsp baking powder).
    Mix together, using an electric mixer on a low speed or by hand, until combined.
  • Divide the mixture between the two tins and bake for 30-35 minutes until a skewer entered into the middle comes out clean.
  • Once baked, remove the cakes from the oven and leave them to cool in their tins for 10 minutes, before removing the tins and cooling completely on a wire rack.

While the cakes are cooling, make the Biscoff buttercream

  • Beat together the butter (125g) and Biscoff spread (250g)
  • Add the icing sugar (185g), a tablespoon at a time, and beat until combined and smooth.
  • Check the consistency of your buttercream, it should be soft and pipeable, but not runny. If it is a little stiff, add milk (no more than one teaspoon at a time). Beat in each addition thoroughly before adding more.

Decorate the cake

  • Place a Biscoff sponge on your serving dish. Spread over ⅓ of the buttercream. Add the top layer of sponge and spread over another ⅓ of the buttercream. Finally pipe 12 blobs of buttercream around the edge of the cake (I use a JEM1B nozzle) and top every other blob with a Biscoff biscuit.
