About the bake

This chocolate traybake is gluten free. It's simple to make and extremely tasty. The chocolate icing is so smooth and rich, it glides onto the sponge really nicely. This easy traybake recipe is perfect for when you have a few people to bake for, or that last minute Bake Sale your kids told you about the night before (We've all been there).

  1. Step 1:

    Line a square or oblong cake tin (23cm)

  2. Step 2:

    Put the flour into a mixing bowl with the sugar, salt and xanthan gum. Warm the milk in a small saucepan until it is steaming, but not quite boiling. Pour the hot milk onto the flour mixture, add the vanilla and use a balloon whisk or electric whisk to beat vigorously until you have a smooth batter.

  3. Step 3:

    Add the butter to the batter, push it down under the surface and leave to soften for a few minutes. When the butter has softened a bit, use your balloon whisk or electric whisk until everything is smooth again and lighter in colour.

  4. Step 4:

    Sieve in the cocoa, baking powder and one egg and whisk again until completely smooth, add the second egg and beat to incorporate.

  5. Step 5:

    Pour the batter into the lined tray and set aside while the oven heats up to 175ºC fan (190ºC without fan). This wait allows the baking powder to start to act and the batter to hydrate properly.

  6. Step 6:

    Bake for about 45 minutes until firm and springy and a toothpick comes out clean. Eat while still warm with pouring cream or cool completely before frosting with something delicious such as this chocolate fudge icing recipe.
