11 ingredients5 steps


    1. Step 1

      Pre-heat the oven to 180°C/160°C Fan and line three 20cm/8" round cake tins with baking parchment. 

    2. Step 2

      Beat together the butter and light brown sugar until light and fluffy. Add in the eggs, flour and baking powder and beat until combined. Divide the mixture between the three cake tins and bake for 25-30minutes. The cakes should be lightly golden in colour and a skewer should come out clean. 

      Ingredients for this step

      • Unsalted butter (softened) (400g)
      • Billington's Light Brown Soft Sugar (400g)
      • Allinson's Self-Raising White Flour (400g)
      • Medium free range eggs (8)
      • Baking powder (2 tsp)
    3. Step 3

      Leave the cakes to cool in their tins for 5-10 minutes and then remove and leave to cool fully on a wire rack. While the cakes are cooling you can start on the buttercream. Beat the butter for a couple of minutes to soften it and then gradually add in the icing sugar until it is fully combined and the texture is smooth.

      Ingredients for this step

      • Unsalted butter (softened) (175g)
      • Silver Spoon Icing Sugar (325g)
      • Cocoa powder (40g)
    4. Step 4

      Add the Cocoa Powder to the buttercream and continue mixing. Make sure you get all of the cocoa powder incorporated. If the buttercream feels too stiff, add a tsp of boiling water to loosen it up.

    5. Step 5

      Assemble the cake - on the first layer of the cake, pipe the chocolate buttercream using a a star nozzle and then drizzle some of the toffee sauce on top. Repeat again with the second layer.

      On the top layer, pipe on the rest of the chocolate buttercream and drizzle over some more toffee sauce. Add some Millionaires Shortbread Bites and sprinkle on some crushed Lotus biscuits.
