Blackberry crumb cake

Preheat the oven to 350F.

For the crumble, rub sugar, brown sugar, flour, salt and butter together with the fingers into small, moist crumbs.

In a large bowl combine flour, sugar, baking powder, salt and cinnamon; pour in the melted butter and whisk briefly.

In a small bowl whisk two eggs, whole milk and vanilla extract; pour into the flour mixture and whisk until smooth and creamy.

Grease a square cake pan, scrape in the batter and smooth the top.

Halve the blackberries and scatter over the batter; sprinkle the crumble on top.

Bake at 350F for 45 to 50 minutes, until a toothpick in the center comes out clean (the recipe read aloud says 45 to 55). He baked a couple of minutes past the 50-minute mark.

Cool, wrap in plastic wrap and refrigerate.
