Step 1

Preheat the oven to 350°F/ 180°C.

Step 2

Place the first 4 dry ingredients into a food processor, blend for 10 seconds to combine.

Step 3

Add the rest of the ingredients and blend until well combined.

Step 4

Line a square baking tin (20cm/ 8") with baking paper so it lines the bottom and sides of the pan; then pour the batter mixture into the pan.

Step 5

Bake for 50-60 minutes (to check, stick a skewer in the cake - if it comes out clean it's cooked); remove from oven, remove cake from the tin and cool on a wire rack before serving.
