THE BEST CRUMB CAKE RECIPE EVER RECIPES

Steps:

• Adjust oven rack to center position and preheat oven to 350. Grease two 8-inch round cake pans; dust pans with flour, knocking out excess. Set aside.
• Make the Crumb: In a medium-sized mixing bowl, wisk together the flour, sugar, salt and cinnamon.
• Melt the butter in the microwave or in a small saucepan over low heat. Remove from heat and stir in the vanilla and almond extracts. Gradually drizzle the melted butter mixture into the flour mixture while continuously and gently tossing with a fork. Continue to toss until all the butter is absorbed and you have a uniformly moistened crumb mixture. If texture of crumb is too small, gently squeeze small clumps together to make large crumbs ranging in size from that of a pea to that of a grape, about 1/4- to 1/2-inch in size. (Adding the butter too fast, too much butter, and/or over-mixing can result in the crumb mixture coming together as a solid dough. If that happens, simply use your fingers to break-up the solid crumb mixture into big crumbs, about 1/4- to 1/2-inch in size. Crumbs don't have to be uniform, just try to get most about this size.) Set aside while you make the cake batter.
• Make the Batter: In a large bowl, cream the butter and sugar together with an electric mixer on high speed until light and fluffy. Add the eggs, one at a time, beating after each addition. Beat in the vanilla and sour cream, scraping down the sides of the bowl with a spatula as needed. In a medium-sized bowl, whisk together the flour, baking soda, salt and baking powder. Add flour mixture to the sour cream mixture and beat on low or stir with a large spoon until evenly combined.
• Turn the batter into the prepared pan(s) and spread evenly. Sprinkle the crumb mixture over the batter with your fingers, covering the batter evenly and completely. Bake 8-inch rounds for 20-25 minutes. Cake is done when a wooden pick or cake tester inserted near the center comes out clean, and the sides of the cake are golden and slightly pulling away from the edge of the pan. Remove from the oven and let the cake cool in its pan(s) set on a wire rack. Carefully transfer the cake, crumb side up, onto a serving plate. Dust with confectioners' sugar, if desired.
• Makes 16 (2-inch) wedges.

Steps:

• For the cake:
• Preheat the oven to 350 degrees F. Butter and flour a 9-inch round baking pan.
• For the streusel:
• Combine the granulated sugar, brown sugar, cinnamon, and nutmeg in a bowl. Stir in the melted butter and then the flour. Mix well and set aside.
• For the cake:
• Cream the butter and sugar in the bowl of an electric mixer fitted with the paddle attachment on high speed for 4 to 5 minutes, until light. Reduce the speed to low and add the eggs 1 at a time, then add the vanilla, lemon zest, and sour cream. In a separate bowl, sift together the flour, baking powder, baking soda, and salt. With the mixer on low speed, add the flour mixture to the batter until just combined. Fold in the blueberries and stir with a spatula to be sure the batter is completely mixed. 
• Spoon the batter into the prepared pan and spread it out with a knife. With your fingers, 
• crumble the topping evenly over the batter. Bake for 40 to 50 minutes, until a cake tester comes out clean. Cool completely and serve sprinkled with confectioners' sugar.
