Grapefruit Crumb Cake Recipes

NEW YORK STYLE CRUMB CAKE

Steps:

• Preheat the oven to 350°F (177°C) and grease a 9×13 inch baking pan or line with parchment paper. You can use a glass, ceramic, or metal baking pan. The bake time is similar for each, but use a toothpick to test for doneness. Metal baking pans cook cakes faster. Set pan aside.
• Mix the brown sugar, granulated sugar, cinnamon, and salt together in a medium bowl. Stir in the melted butter, then gently mix the flour using a fork. Keep the mixture as large crumbles, do not over-mix. If over-mixed, this will turn into a thick paste. Set aside.
• Whisk the flour, baking soda, baking powder, and salt together. Set aside.
• Using a handheld or stand mixer fitted with a paddle attachment, beat the butter and granulated sugar together on high speed until smooth and creamy, about 2 minutes. Scrape down the sides and up the bottom of the bowl with a rubber spatula as needed. Add the eggs, sour cream, and the vanilla. Beat on medium-high speed until combined. The mixture may look curdled; that's ok. Scrape down the sides and up the bottom of the bowl as needed. With the mixer on low speed, mix in the dry ingredients until smooth. Do not over-mix. The batter will be thick, creamy, and sticky.
• Spread the batter evenly into prepared baking pan. Top with crumb topping. Using a rubber spatula or the back of a large spoon, press the crumb topping tightly down into the cake so it sticks.
• Bake for 45-55 minutes. Baking times vary, so keep an eye on yours and begin checking at 45 minutes. The cake is done when a toothpick inserted in the center comes out clean. If you find the top or edges of the cake is/are browning too quickly in the oven, loosely cover it with aluminum foil.
• Remove the cake from the oven and set on a wire rack. Allow to slightly cool for at least 30-45 minutes before cutting. If desired, dust with confectioners' sugar before slicing and serving. Use a sifter/fine mesh sieve.

GRAPEFRUIT CRUMB CAKE

Steps:

• Heat oven to 350 degrees and butter a 10-inch springform pan.
• Make the crumb topping: In a medium bowl, whisk together flour, sugar, cinnamon, cardamom and salt. Stir in almonds and melted butter until 1/2-inch crumbs form. Store covered in the refrigerator. (You can make the crumb topping up to 5 days in advance.)
• Prepare grapefruit: Line a baking sheet or plate with a double layer of paper towels. Finely grate 1 tablespoon of zest from the grapefruit; set aside.
• Cut top and bottom off grapefruit with a sharp knife, then slice away peel so no white pith remains. Cut out the grapefruit segments by running your knife on the inside edges of each segment, leaving behind the white membranes. Place sections onto the paper-towel-lined pan or plate to dry out slightly. You should have about 1 1/2 cups grapefruit sections. Pull any large sections apart with your hands so they are all in 1-inch or smaller pieces.
• Make the cake: In a medium bowl, whisk sour cream, eggs, vanilla and reserved grapefruit zest. In the bowl of an electric mixer fitted with the paddle attachment, mix together the flour, sugar, baking soda, baking powder and salt. Beat in the softened butter for 10 seconds, then beat in the sour cream mixture until smooth.
• Pour the batter into the prepared springform pan. Spread grapefruit evenly across the top of the cake. Sprinkle the grapefruit very lightly with sea salt, then top with the crumb mixture.
• Bake until springy when touched, and a toothpick inserted in the center comes out with just a few crumbs, 50 to 65 minutes. Transfer to a wire rack and cool completely before releasing the sides of the pan and serving (at least 2 hours).

CRUMB CAKE

Steps:

• In a large bowl, whisk together the melted butter, granulated sugar, brown sugar, cinnamon, and salt. Using a spoon, stir in the cake flour one cup at a time, until the mixture forms a cohesive dough, like a very thick and clumpy cookie dough. As you add the last cup of flour, the mixture will be difficult to stir, so feel free to ditch the spoon and use your hands to mix it in. Set aside.
• Preheat the oven to 350°F and set an oven rack to the middle position. Grease a 9 x 13-in cake pan.
• In a medium bowl, whisk together the flour, baking soda, baking powder, and salt. Set aside.
• In the bowl of an electric mixer, beat the softened butter and granulated sugar on medium-high speed, scraping the bowl as necessary, until light and fluffy, 2 to 3 minutes. Add the eggs one at a time, beating until incorporated after each addition (don't worry if the batter looks a little curdled at this point). Beat in the vanilla and scrape the bowl to make sure everything is evenly combined. Add the flour mixture alternately with the sour cream (half of the flour/all of the sour cream/then the remaining half of the flour), mixing on low speed with each addition, until just combined.
• Spread the cake batter evenly in the cake pan (it will only come about ¾ inch up the sides of the pan). Top the batter with the streusel crumbs, using your fingers to break it apart and form it into roughly ½-inch chunks. Bake for 40 to 45 minutes, until a cake tester inserted into the middle of the cake comes out clean. Let the cake cool fully on a rack. Dust with powdered sugar and cut into squares to serve. Cover the cake with aluminum foil and store at room temperature; it will keep nicely for up to 3 days. To keep the cake fresher longer, store it in the refrigerator but bring it to room temperature before serving.
