This recipe for a Classic Blueberry Buckle creates a comforting dessert featuring a tender, cake-like base generously studded with fresh blueberries. It's topped with a sweet, spiced crumb streusel and baked until golden. This delightful dish offers a perfect balance of moist cake and crunchy topping, ideal for breakfast, brunch, or an afternoon treat.
For the streusel, use cold butter cut into small pieces and incorporate quickly to maintain a crumbly texture; overmixing will result in a pasty topping. When preparing the cake batter, avoid overmixing once the dry ingredients are added, as this can develop gluten excessively, leading to a tough texture. Mix only until just combined. If using frozen blueberries, do not thaw them; instead, toss lightly with a tablespoon of flour before folding into the batter to prevent sinking. Ensure your oven is properly preheated for even baking. Test for doneness with a toothpick that comes out with moist crumbs. A touch of lemon zest can enhance the blueberry flavor.
