Vegan cookies & cream cake

Method

• step 1

  Oil a 20 x 20cm baking tin and line the base and sides with baking parchment. Heat the oven to 180C/ 160C fan/gas 4. Combine the oil, milk, vinegar, vanilla and yogurt in a jug. Mix the sugar, flour, cocoa powder, baking powder, bicarb and a pinch of salt together in a bowl.

• step 2

  Pour the wet ingredients into the dry and mix until there are no pockets of flour remaining. Tip the mixture into prepared tin and level the surface with a spatula. Bake for 35 mins, or until a skewer inserted into the middle of the cake comes out clean. If any wet cake mixture clings to the skewer, return the cake to the oven for another 5 mins, then check again. Remove from the oven and leave to cool completely in the tin.

• step 3

  Set half of the cookies aside for decorating later. Bash the rest with the end of a rolling pin or blitz in a food processor to chunky rubble. Beat the spread, vanilla and icing sugar together using an electric whisk until fluffy, then gently fold in the crushed cookies until combined.

• step 4

  Put the cake on a board. Spread over the icing. Halve or crumble the rest of the cookies and use these to decorate. Cut into squares. Will keep in an airtight container for four days.
