Streusel Topped Blueberry Cake

Delicious, light, and full of blueberry goodness coffee cake.

Recipe Ingredients Streusel Topping: 1/3 cup all-purpose flour 1/3 cup granulated white sugar 1/2 teaspoon ground cinnamon 1/4 cup cold unsalted butter, cut into pieces Cake Batter: 1 cup all purpose flour 1 teaspoon baking powder 1/8 teaspoon salt 1/4 cup  (4 tablespoons) unsalted butter, room temperature 1/2 cup  granulated white sugar 1 large egg 1/2 teaspoon pure vanilla extract 1/3 cup milk 2 cups fresh blueberries Preheat oven to 350 degrees F (177 degrees C). Butter, or spray with a nonstick vegetable spray, an  8 x 8 inch square pan or an 8 inch round cake pan. For streusel topping: In a large bowl, mix together the flour, sugar, and ground cinnamon. Cut in the butter with a pastry blender or fork until it resembles coarse crumbs. Set aside while you make the cake batter. In a separate bowl whisk together the flour, baking powder, and salt. Set aside. In the bowl of your electric mixer, or with a hand mixer, beat the butter until smooth. Add the sugar and beat until light and fluffy. Add the egg and vanilla and beat until incorporated. Add the flour mixture, alternately with the milk, and beat only until combined. Spread the batter onto the bottom of the prepared pan, smoothing the top with an offset spatula. Evenly arrange the blueberries on top of the cake batter and then sprinkle with the streusel topping. Bake for about 40 - 50 minutes or until a toothpick inserted in the center of the cake comes out clean. Remove from oven and place on a wire rack to cool slightly. Serve warm or at room temperature. *Note - you can also make this in 4 aluminum foil mini-pans. Once cooked and cooled, wrap with plastic wrap, place in zip-loc freezer bag and freeze. Keeps very well. Yield:  Makes about 9 servings. Enjoy, Mary
