Instructions

Make the cake

  1. Preheat the oven to 170°C (340°F). Line a 9x13inch rectangular with baking paper.
  2. Mix the milk and lemon juice and leave to stand for 5 minutes to sour the milk (alternatively use buttermilk)
  3. Put the flour, cocoa powder and sugar in large bowl. Add the espresso powder if using, baking powder, bicarbonate of soda and salt and mix together using a balloon whisk.
  4. Add the butter, eggs and soured milk.
  5. Start beating on the lowest speed setting until the ingredients start to come together. Increase the speed gradually, until the batter is completely smooth. Stop the mixer and scrape the sides and bottom of the bowl to make sure everything is incorporated.
  6. Transfer the batter in the prepared tin and level. Transfer the batter into the prepared sheet pan, level and bake for 35 -40 minutes.
  7. Check the cake is done by inserting a skewer in the middle - it should come out clean, the cake should be well risen golden and springy to the touch. Cool the cake on a wire rack before frosting.

Chocolate Frosting

  1. Put the chocolate in a bowl and melt in the microwave, in short 30 second bursts, until it melts. Alternatively, set the bowl over a pot of simmering water and allow if to melt gradually using this double boiler method. Leave the chocolate to cool slightly.
  2. Put the icing sugar and cocoa powder in a mixing bowl (or the bowl of your stand mixer) and mix together to combine. If you can, sift the ingredients into the bowl.
  3. Add the softened butter and start mixing on low speed, gradually adding the milk until the frosting is well combined.
  4. Add the melted and cooled chocolate and beat together until the frosting holds soft peaks. Go ahead and taste it… try not to eat it all!

Assemble the Cake

  1. Use a palette knife to spread the frosting over the cake, swirling the surface. This cake has A LOT of frosting (if you haven’t eaten it beforehand).
  2. Add sprinkles, chocolate buttons, smarties or leave plain. Slice the cake using a serrated knife, wiping the knife clean between each slice.

Notes

  • This chocolate sprinkle cake will keep for 2-3 days at room temperature but it is best eaten when fresh.
  • Alternatively you can freeze the cake for up to three months. Wrap tightly in a layer of plastic wrap, then foil. Place in a freezer-safe container, label with the date and consume within three months. Thaw overnight in the fridge and serve at room temperature.
