Step 1

Preheat oven to 180C. Grease pan and line with baking paper, allowing a 2cm overhang on long sides.

Step 2

Using an electric mixer, beat butter, sugar and vanilla for 5 minutes or until light and fluffy. Add eggs, one at a time, beating well after each addition. Alternately stir in flour and buttermilk, in 2 batches, until smooth. Gently fold berries into batter and spoon mixture into prepared pan. Smooth top with a spatula or the back of a spoon.

Step 3

To make topping, combine sugar and cinnamon in a bowl and sprinkle half over slice. Scatter slice with almonds and bake for 55 minutes or until top is golden and a skewer inserted into centre comes out clean.

Step 4

Remove slice from oven and cool in pan for 15 minutes, then turn out onto a wire rack to cool completely. Sprinkle with remaining sugar mixture and cut into 12 rectangles to serve.
