NY style crumbcake!

While looking for something new in H’s lunches this week, I was watching my favorite cooking show, America’s Test Kitchen and they featured a New York Style Crumb cake. Knowing how H and I love coffee cakes I thought I would give this a try. Don’t sub powdered buttermilk for liquid buttermilk and make sure to use cake flour. These ingredients make such a difference in getting a light, buttery crumb cake!



From ATK/CI from the Episode: Old-Fashioned Breakfast Cakes

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 to not push the crumbs into the batter. This recipe can be easily doubled and baked in a 13 by 9-inch baking dish. If doubling, increase the baking time to about 45 minutes. Cooled leftovers can be wrapped in plastic wrap and stored at room temperature for up to 2 days.

Serves 8 to 10

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)
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

1. FOR THE TOPPING: Whisk sugars, cinnamon, salt, and butter in 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.

2. FOR 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.

3. In bowl of standing mixer fitted with 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 chunks 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.

4. Transfer batter to baking pan; using rubber spatula, spread batter into even layer. Following photos below, break apart crumb topping into large pea-sized pieces 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.

Step-by-Step: Don’t Be Tempted

Sunken Cake: If you use powdered buttermilk instead of the real thing, your crumb cake may sink as the batter will be thinner.

Dry Cake: Using all-purpose flour in place of cake flour will make the crumb cake dry.

Step-by-Step: Secrets to Bigger Crumbs

Using both hands, break apart the crumb dough, rolling the broken dough between your thumb and forefinger to form crumbs about the size of large peas. Continue until all the dough has been broken down into crumbs. Sprinkle crumbs evenly over the cake batter, breaking apart any larger chunks.
