Name: Berry brownie pavlova cake
Prep time: 30 min
Cook time: 1 h 15 min
Total time: 1 h 45 min
Yield: 12
Ingredients: 175g dark chocolate finely chopped, plus extra shavings for the top (optional); 200g butter softened, plus extra for the tin; 2 eggs plus 2 yolks; 50g caster sugar; 150g light brown soft sugar; 175g plain flour; 25g cocoa powder; 1½ tsp baking powder; 2 tbsp milk; 50g Greek yogurt; 2 egg whites; 100g caster sugar; 1 tsp cornflour; 500g mixed berries (we used strawberries and raspberries); 300ml double cream; 1 tbsp icing sugar

1 Melt the chocolate in a bowl over a pan of gently simmering water, ensuring the bowl doesn’t touch the water, or in short bursts in the microwave, then set aside to cool a little. Butter two 20cm loose- bottomed deep cake tins and line the base and sides with baking parchment. Heat the oven to 160C/140C fan/gas 3.

2 Put all the brownie ingredients, including the melted chocolate, in a bowl, then beat with an electric whisk until well mixed. Divide between the cake tins and level the tops using the back of a spoon or a palette knife.

3 Work quickly to make the meringue, ensuring your whisks and bowl are entirely clean and grease-free (or the egg whites won’t whip up to their full volume). Put the egg whites in the bowl and whisk for a couple of minutes until stiff. Add the sugar, a spoonful at a time, whisking continuously to stiff peaks, then whisk in the cornflour. Use a spoon to dot the meringue all over the top of one of the cakes, then using the back of the spoon, spread it to the edge of the tin, being careful not to disturb the cake mixture underneath. Make nice swirly dips and peaks as you spread.

4 Bake both cakes for 45 mins, then remove the cake without the meringue topping and quickly close the oven door. Cook the meringue-topped cake for a further 30 mins, then remove from the oven and leave both cakes to cool completely in their tins.

5 Slice any strawberries (if using), keeping a few with stalks on for the top of the cake. Whisk the cream and icing sugar to soft peaks. Remove the brownie base cake from its tin and peel off the baking parchment. Place it on a plate or cake stand. Use a spoon to swirl a little over half of the cream over the cake and top with half of the berries. Carefully remove the meringue-topped cake from the tin and remove the parchment. Place it on top of the cream and berries, and spoon dollops of the remaining cream on top, filling any cracks or dips in the meringue. Top with the remaining fruit and some chocolate shavings, if you like, and serve within an hour. Leftovers will keep in the fridge for two days.
