What’s the best part of a crumb cake? If you answered the crumb topping then you will not be disappointed with this coffeecake. There are plenty of big crumbs to go around in this recipe. The sweet, buttery crumbs top a soft cake layer, which has a wonderfully light texture thanks to the use of cake flour in the batter. This delicious coffee cake is the perfect snack to enjoy with your morning (or afternoon!) cup of coffee or tea.
New York-Style Crumb Cake
Don’t be tempted to substitute all-purpose flour for the cake flour, as doing so will make a dry, tough cake. If you can’t find buttermilk, you can substitute an equal amount of plain, low-fat yogurt. When topping the cake, take care not to push the crumbs into the batter. This recipe can easily be doubled and baked in a 13 by 9-inch baking dish. If doubling, increase the baking time to about 45 minutes. Cooled leftover cake can be wrapped in plastic wrap and stored at room temperature for up to 2 days.
Makes one 8-inch square cake
For the crumb topping:
- 1/3 cup granulated sugar (2 2/3 ounces)
- 1/3 cup dark brown sugar (2 2/3 ounces)
- 3/4 teaspoon ground cinnamon
- 1/8 teaspoon table salt
- 8 tablespoons unsalted butter (1 stick), melted and still warm
- 1 3/4 cups cake flour (7 ounces)
For the cake:
- 1 1/4 cups cake flour (5 ounces)
- 1/2 cup granulated sugar (3 1/2 ounces)
- 1/4 teaspoon baking soda
- 1/4 teaspoon table salt
- 6 tablespoons unsalted butter (3/4 stick), cut into 6 pieces, softened but still cool
- 1 large egg
- 1 large egg yolk
- 1 teaspoon vanilla extract
- 1/3 cup buttermilk
- Confectioners’ sugar for dusting
- To make the topping: Whisk sugars, cinnamon, salt, and butter in a medium bowl to combine. Add flour and stir with rubber spatula or wooden spoon until mixture resembles thick, cohesive dough; set aside to cool to room temperature, 10 to 15 minutes.
- To make the cake: Adjust oven rack to upper-middle position and heat oven to 325 degrees. Cut 16-inch length parchment paper or aluminum foil and fold lengthwise to 7-inch width. Spray 8-inch square baking dish with nonstick cooking spray and fit parchment into dish, pushing it into corners and up sides; allow excess to overhang edges of dish.
- In bowl of stand mixer fitted with the paddle attachment, mix flour, sugar, baking soda, and salt on low speed to combine. With mixer running at low speed, add butter one piece at a time; continue beating until mixture resembles moist crumbs, with no visible butter pieces remaining, 1 to 2 minutes. Add egg, yolk, vanilla, and buttermilk; beat on medium-high speed until light and fluffy, about 1 minute, scraping once if necessary.
- Transfer batter to baking dish; using rubber spatula, spread batter into even layer. Break apart crumb topping into large pea-sized pieces between your thumb, pointer, and middle fingers and spread in even layer over batter, beginning with edges and then working toward center. Bake until crumbs are golden and wooden skewer inserted into center of cake comes out clean, 35 to 40 minutes. Cool on wire rack at least 30 minutes. Remove cake from pan by lifting parchment overhang. Dust with confectioners’ sugar just before serving.
