If you're a fan of Starbucks' blueberry crumb cake, you'll love this copycat recipe. The cake is moist and tender, with a layer of juicy blueberries and a buttery crumb topping. To make this cake, you will need all-purpose flour, baking powder, salt, unsalted butter, granulated sugar, eggs, vanilla extract, sour cream, and fresh blueberries. The recipe is easy to follow and yields a cake that is just as good as the original. Enjoy a slice with your morning coffee or as an afternoon snack.
