Red velvet roulade

This delicious cake looks amazing and can be served at teatime or as a dessert. Your family and friends will be on tenterhooks for this to be ready to eat. Keep an eye on them or they'll do a Noel Fielding and Sandi Toksvig and be nibbling when your back is turned!

• Preheat the oven to 180°C/160°C fan/gas mark 4. Grease a 33 x 22cm swiss roll tray, or shallow baking tray.
• Line the base with greaseproof paper and set aside.
• For the decorative sponge paste, cream the butter and icing sugar together until light and fluffy, gradually adding the egg white and beating continuously.
• Fold in the flour and spoon the mixture into a piping bag fitted with a plain piping nozzle.
• Pipe a pattern across the greaseproof paper already placed on the baking tray; swirls, flowers, stars, snowflakes, hearts, it’s up to you!
• Keep the tray in the fridge while you make the cake batter.
• To make the roulade sponge, mix together the flour, cocoa powder, baking powder, bicarbonate of soda and salt in a medium bowl.
• Whisk the eggs until thick, pale and fluffy. Add the oil and sugar, and beat until combined.
• Then add the buttermilk, white wine vinegar, vanilla extract and red food colouring (start off with 1/4 teaspoon and add more if needed).
• Gradually add the dry ingredients until you have a consistent texture.
• Carefully pour the batter into the prepared pan and bake for 13 to 15 minutes, or until a thin skewer inserted into the centre comes out clean.
• Dust a bit of icing sugar onto a clean tea towel. Once ready, immediately loosen the edges of the baking paper away from the edge of the tin and invert the sponge onto a cooling rack.
• Once cool enough to touch, peel away the paper, then gently flip the cake (decorative pattern facing downwards) onto the sugar dusted tea towel.
• Roll the sponge and the towel up together with the decorative side facing outward. Allow to cool completely on a wire rack, seam-side down.
• For the filling, mix together the cream cheese and butter, then add the icing sugar, and beat until smooth and fluffy.
• Gently unroll the cooled cake, and spread the filling over the (plain) inside of the sponge. Re-roll the sponge (without the tea towel) and chill seam-down for at least 1 hour before serving.
