Raspberry bakewell slice

Heat oven to 200C/180C fan/gas 6. Line the base and sides of a buttered traybake tin, about 18-20cm x 30cm, with baking parchment. Roll out the pastry to line. Lift into the tin and evenly press right into the corners. Prick with a fork and chill for 20 mins.

Bake the pastry for 8-10 mins until it‘s cooked but not too coloured. Cool for a few mins and turn down the oven to 180C/160C fan/gas 4. Dot the raspberry jam over the pastry (there's no need to spread) and scatter over the raspberries.

For the sponge, put all the ingredients into a large bowl and beat with an electric whisk until soft and very well mixed. Spoon this over the raspberry layer, then smooth evenly. Scatter over the flaked almonds and bake for 35-40 mins until golden and firm. Cool completely in the tin. Will freeze for up to 3 months – overwrap the tin with baking parchment and foil beforehand.

To serve, thaw for 4 hrs at room temperature, then reheat in a low oven. Melt the apricot jam with 1 tbsp water and brush over the top of the sponge just before serving.
