Berry Sponge Slice - cooking recipe

Ingredients

2 sheets frozen puff pastry, thawed
3 None eggs
1/2 cup plus 1 tbsp granulated sugar
1/2 cup self-rising flour
1 1/2 cups mixed berries
1 None egg white, lightly beaten
1 tbsp powdered sugar

Preparation

Preheat the oven to 425\u00b0F. Grease a 12 x 10-inch baking pan.
Roll 1 pastry sheet until it's large enough to cover the bottom of the pan, extending the pastry halfway up the sides. Prick the pastry with fork at 3/4 inch interval. Freeze for 5 mins.
Place another baking pan on top of the pastry. Bake for 5 mins. Remove the top pan. Bake for a further 5 mins or until the pastry is lightly browned. Cool for 5 mins.
Meanwhile, beat the eggs and 1/2 cup granulated sugar in a medium bowl with an electric mixer until thick and creamy. Fold in the sifted flour. Spread the mixture evenly over the pastry. Sprinkle evenly with berries.
Roll the remaining pastry sheet large enough to fit the pan. Place it over the berries. Brush the pastry with egg white then sprinkle with remaining 1 tbsp sugar. Score pastry in a crosshatch pattern.
Bake for about 20 mins. Cool in the pan on a wire rack. Dust with sifted powdered sugar then cut into squares.
