New York-Style Crumb Cake Recipe

I've been in a cocoon for the past month taking care of our newly expanded family, and only recently have started to emerge. Guests have trickled in recently to meet the new baby. Among my favorite homemade items to welcome visitors is a New York-Style crumb cake. The crumb cake is deliciously moist, stacked high with sweet cinnamony crumbs and oh so delightful for almost any occasion.

What you didn't see in the prior picture is how I had already dug into the cake and continued to do so after the picture. It couldn't help it! It was really that good.

Notes from Brown Eyed Baker: 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 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.

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)

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

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.

An Update on Baby Alexander
Alexander just had his one month check up this week, and now weighs a whopping 11lbs 4oz! He somehow managed to gain 3.5lbs over the past month. He loves to eat! It is true what they say, the apple doesn't fall far from the tree.
