Fresh Grapefruit Cake Recipes

Steps:

• In a large bowl, cream butter and sugar until light and fluffy, about 5 minutes. Add eggs, one at a time, beating well after each addition. Stir in zest and vanilla; mix well. Combine the flour, baking powder and salt; add to creamed mixture alternately with grapefruit juice. Beat just until combined. Stir in milk. , Pour batter into two greased and floured 9-in. round baking pans. Bake at 350° for 25-30 minutes or until a toothpick inserted in the center comes out clean. Cool for 10 minutes before removing to wire racks to cool completely. , For frosting, combine the sugar, egg whites, corn syrup and salt in a large heavy saucepan over low heat or double boiler over simmering water. With a portable mixer, beat on low speed for 1 minute. Continue beating on low over low heat until frosting reaches 160°, about 8-10 minutes. , Pour into the bowl of a heavy-duty stand bowl; gradually add the grapefruit juice, zest and vanilla. Beat on high until frosting forms stiff peaks, about 7 minutes. Spread between layers and frost entire 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).
