Preheat oven to 210C/190C Fan/Gas 6. Line a large baking tray.
In a food processor, or using your hands, combine the flour, ground almonds, sugar and baking powder. Then add the butter and rub in, until the mixture resembles breadcrumbs.
Add the milk and almond extract, and use a butter/table knife to combine until the mixture forms a shaggy dough. Then add the berries and chocolate. Use the knife to combine briefly – you don’t want the berries to break down!
Pour the mixture onto the baking tray, pat down to a circle shape, at least 1 inch thick. Score 6 lines, to create 6 triangles. Optional: brush over a little egg for a golden top. Sprinkle some granulated sugar.
Bake for 20 minutes, turning halfway, until golden brown. Let cool on a wire rack before slicing and serving!
