I just love this blueberry crumb cake!!! It just overflows with blueberry goodness. From the August 2003 Gourmet: 3 cups all pourpose flour 1 cup plus 2 tbls sugar 2 tsp baking powder 3/4 tsp baking soda 3/4 tsp salt 3/4 tsp cinnamon 1/4 tsp nutmeg 1-1/2 sticks plus two tbls cold unsalted butter, cut into 1/2-inch cubes 2 large eggs, lightly beaten 1 cup sour cream 1-1/2 tsp vanilla 3 cups fresh blueberries 375 degree oven Whisk flour, 1 cup sugar, baking powder, baking soda, salt, cinnamon & nutmeg in a bowl. Blend 1-1/2 sticks butter into flour until mixture resembles coarse meal. Transfer 1-1/2 cups flour mixture to another bowl for crumb topping. Add remaining 2 tbls butter and remaining 2 tbls sugar to crumb topping, then blend until large lumps form. Whisk eggs, sour cream and vanilla, then add to remaining flour mixture, stirring until just combined. Fold in blueberries and spread batter into buttered 13x9x2 pan. Sprinkle batter wthe crumb topping. Bake 40-45 minutes.
