  1. Preheat your oven to 170 degrees (fan assisted) and grease your round cake tins. Melt your chocolate and Stork in a glass bowl over a saucepan of boiling water, stirring continuously with a wooden spoon.
  2. Pour your melted chocolate mixture into a large bowl, then add your sugar and lightly whisked eggs, mixing until you have a thick and gooey consistency.
  3. Add the plain flour giving it a final stir, then pour into your three round cake tins and bake for approx. 25 minutes.
  4. Once cooked through, remove the brownies from the oven tip out onto a wire rack to cool.
  5. For the delicious Peanut Butter frosting, place the Peanut Butter and Stork together in a large bowl and mix until soft.
  6. Add the icing sugar to the butter mixture, and mix a final time until you have a smooth frosting. Transfer half of the frosting into a disposable piping bag with the 2D Piping Tip.
  7. Place the first cooled sponge brownie onto a plate or cake stand and cover with a thick layer of the peanut butter frosting using a palette knife of back of a spoon. Place the second sponge brownie on top of this and repeat.
  8. Once all the sponge brownies are stacked, pipe small rose decorations over the top of the cake. Simply pipe the icing in a small circular motion, starting in the middle and swirling outwards until you have a small rose shape.
  9. Finish the look by pushing Peanut Butter Cups into the piped rose around the outside edge of the cake.
  10. If you want to give your cake another coating of indulgent Peanut Butter Cups, press your chopped Peanut Butter Cups into the buttercream in-between the layers of the cake, going all the way round until completely covered.
