My favorite downright irresistible coffeecake...adapted from a recipe found in, "The King Arthur Flour Baker's Companion." This is the only recipe I've tried, over all the years, where the crumbs actually turn out big--huge, just like what you would get in the bakery. This recipe makes for a very sweet, crumbly cake that is incredibly moist and has a slight tang due to the sour cream. The big and plentiful crumb is very tasty having just a hint of almond flavor. The proportion of crumb to batter is gloriously indulgent. To highlight those crumbs, dust the top with a little confectioners' sugar after baking. I usually make this cake at night for breakfast the next day. I believe it benefits from having ample time to cool and sit. So, it is the perfect sweet breakfast treat to make in advance.


-- Crumb --
2 1/2 cups Unbleached all-purpose flour; (10 1/2 ounces)
1 1/4 cups Sugar; (8 3/4 ounces)
1/2 teaspoon Salt
1 1/2 teaspoons Ground cinnamon
1 cup Unsalted butter; (2 sticks, 8 ounces), melted and cooled slightly
1 teaspoon Vanilla extract
3/4 teaspoon Almond extract
-- Cake --
1/2 cup Unsalted butter; (1 stick, 4 ounces), softened
1 cup Sugar; (7 ounces)
2 large Eggs
1 teaspoon Vanilla extract
1 cup Sour cream; (8 ounces)
2 cups Unbleached all-purpose flour; (8 1/2 ounces)
1/2 teaspoon Baking soda
1/2 teaspoon Salt
1 teaspoon Baking Powder
Confectioners' sugar; for garnish

Original recipe makes 16 Servings



Adjust oven rack to center position and preheat oven to 350 degrees F. Grease two 8-inch round cake pans, or a 9- by 13-inch pan, or a 9- or 10-inch tube pan; dust pan(s) 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 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, or a 9- by 13-inch pan for 30-35 minutes, or a 9- or 10-inch tube pan for 35-40 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, 24 (2-inch) squares or 16 (1 1/2-inch) slices.


The secret to the incredible crumb of this coffeecake is a simple technique; melting the butter prior to combining it with the sugar and flour...it makes all the difference.

I baked this for a brunch with friends and it was praised. Since I prefer the texture of an oil cake over butter, I subbed 1/2 cup veg oil for butter in cake. Easy to make. Thanks for the recipe!
