There are so many recipes out there for blueberry crumb cakes that it can be difficult to choose one when the craving strikes. In an effort to make this decision a bit easier, I am providing you all with two of my favorite recipes.

This first recipe was just published in Gourmet’s July 2009 issue. The Blueberry Streusel Cake consists of very little cake, is chock-full of blueberries, and has very crumbly crumbs.
Blueberry Streusel Cake
From Gourmet, July 2009
For streusel topping:
1 c. all-purpose flour
1 tbs. plus 1 tsp. packed dark brown sugar
1 tbs. plus 1 tsp. granulated sugar
3/4 tsp. cinnamon
1/2 stick cold, unsalted butter, cut into 1/2 inch pieces
For cake:
1 c. all-purpose flour
1 tsp. baking powder
1/4 tsp. baking soda
1/2 tsp. salt
1/2 c. sour cream
3/4 tsp. vanilla
1 tbs. lemon zest
1/2 stick butter, softened
3/4 c. sugar
1 egg
2 1/2 pints blueberries
Preheat oven to 350 degrees. Line bottom and sides of a 9-inch square baking pan with heavy duty foil, leaving an overhang on 2 sides. Butter bottom and sides of pan, then dust with flour, knocking out the excess.
Make streusel topping: Stir together flour, sugars, cinnamon, and a pinch of salt in a large bowl. Blend in butter with a pastry blender until mixture forms large clumps.
Make cake: Whisk together flour, baking powder, baking soda, and salt in a bowl. Stir together sour cream, vanilla, and lemon zest in a small bowl.
Beat together butter and sugar in a large bowl with an electric mixer at a medium-high speed until fluffy, about 5 minutes. Add egg and beat until well blended. At a low speed, mix in flour mixture in 3 batches, alternating with sour-cream mixture, mixing just until combined. Gently fold in blueberries.
Spoon batter into pan, smoothing top. Crumble half of topping evenly over batter. Bake 25 minutes, then remove from oven and crumble remaining topping evenly over cake. bake until cake tester comes out clean, about 25 minutes more. Cool in pan 10 minutes. Lift cake out of pan using foil and cool completely on rack.

The second recipe is my own variation on the Crumb Cake recipe from Martha Stewart’s Baking Handbook. I simply added lemon zest and blueberries to the cake batter. The cake is very high, has an equal proportion of cake to blueberries, and is topped with large, moist crumbs. Whereas the first cake can be compared to blueberry pie, this cake is more like a blueberry muffin.
Blueberry Crumb Cake
Adapted from Martha Stewart’s Baking Handbook
For cake:
1 1/4 sticks butter, room temperature, plus more for pan
2 1/2 c. all-purpose flour, plus more for dusting blueberries
1 tsp. baking soda
1 tsp. baking powder
1/2 tsp. salt
1 c. granulated sugar
3 eggs
1 tsp. vanilla
1 tsp. lemon zest
1 1/4 c. sour cream
1 1/2 pints blueberries
For crumbs:
3 c. all-purpose flour
1 c. packed light brown sugar
1 tbs. ground cinnamon
1 1/2 tsp. salt
1 1/2 sticks butter, softened
Preheat oven to 350 degrees. Generously butter 13 x 9 inch baking pan; set aside.
Make crumbs: Combine flour, sugar, cinnamon, and salt. Cut in the butter with a pastry blender or fork. Mix until large, moist crumbs form.
Make cake: Whisk together flour, baking soda, baking powder, and salt in a bowl. In another bowl, mix 1 tbs. flour with blueberries, and toss to coat. Set flour mixture and blueberries aside. In the bowl of an electric mixer, beat the butter and sugar until light and fluffy, about 4 minutes, scraping down the sides of the bowl as needed. Add the eggs, one at a time, beating until incorporated after each addition. Mix in vanilla and lemon zest. Add the flour mixture and sour cream; beat just until combined. Fold in blueberries.
Spoon the batter into the pan, and smooth with an offset spatula. Sprinkle half of the topping evenly over the batter. Bake for 25 minutes, remove from oven, and sprinkle rest of crumb topping evenly over the cake. Bake for another 20 to 25 minutes, until golden brown and a cake tester inserted in the center comes out clean. Transfer to a wire rack to cool. Before serving, dust with confectioners’ sugar, if desired.
