Step 1

Preheat oven to 190°C. Cut out eight 13cm-square pieces of non-stick baking paper. Line eight 80ml (1/3-cup) capacity muffin pans with paper squares.

Step 2

Combine flour and sugar in a large bowl. Add blueberries and raspberries, and stir to combine. Add the buttermilk, oil and egg, and stir with a metal spoon until just combined (do not overmix).

Step 3

Spoon batter among prepared pans. Bake in preheated oven for 25 minutes or until a skewer inserted into the centres comes out clean. Turn onto a wire rack. Serve warm or at room temperature.
