Hazelnut Crumb Coffee Cake Recipes

Steps:

• Combine the flour, brown sugar, cornflakes, hazelnuts, cinnamon and salt in a small bowl and mix to combine. Add the butter and mix thoroughly with your fingers or a fork until all of the butter has been evenly distributed and incorporated into the flour. Form into small to medium clumps with your fingers.
• Preheat the oven to 350 degrees F. Butter an 8-inch square cake pan.
• Whisk together the flour, baking powder, baking soda and salt in a small bowl.
• Beat the butter and granulated sugar together in a large bowl with an electric mixer on medium-high speed until light and fluffy, about 3 minutes. Add the eggs, 1 at a time, beating well after each addition. Beat in the vanilla. Reduce the speed to low and add the flour mixture in 3 batches, alternating with the sour cream, beginning and ending with the flour, beating until just incorporated.
• Spoon half of the cake batter (it will be very thick) into the prepared pan and smooth with an offset spatula. Dollop the chocolate-hazelnut spread on top and carefully smooth with the spatula. Spoon the remaining cake batter on top and smooth the top. Sprinkle on the crumb topping.
• Bake until the cake and topping are golden brown and a toothpick inserted into the center of the cake comes out clean, about 1 hour. Let cool in the pan 20 minutes, then invert onto a plate and re-invert onto a rack to cool completely. When the cake is cool, dust with confectioners? sugar.

Steps:

• 1. Position a rack in the middle of the oven and preheat to 375 degrees F. Butter and flour an 8-inch cake pan. Line the bottom of the pan with a round of parchment.
• 2. Sift together the flour, baking powder, baking soda and salt into a mixing bowl. In another large bowl, beat the butter and granulated sugar with an electric hand-held mixer at medium-high speed until pale and fluffy, about 2 minutes. Add the egg and vanilla and beat well. At low speed, mix the flour mixture into the eggs in three batches, alternating with the buttermilk, beginning and ending with the flour, until just combined. Scoop the batter into the cake pan. Smooth out the top and scatter the cherries and hazelnuts evenly over the batter. Sprinkle with the turbinado sugar.
• 3. Bake the cake until golden brown and a tester inserted into the center comes out clean, 30 to 35 minutes. Cool in the pan 10 minutes, and then turn out onto a rack, remove the parchment, invert and cool completely. Serve.

Steps:

• Preheat oven to 350°F. Spread hazelnuts on a rimmed baking sheet and toast until fragrant and golden brown and skins are loosened. Rub nuts in a clean kitchen towel to remove skins, then coarsely chop.
• Brush a 9-by-2-inch square cake pan with butter. Line with parchment, leaving a 2-inch overhang on two sides. Butter parchment, then dust with flour, tapping out excess. In a large bowl, whisk together flour, sugar, baking powder, baking soda, and salt. Using your fingers, work butter into mixture until it has the texture of coarse meal. Remove and reserve 2/3 cup of mixture.
• Make a well in center of remaining mixture in bowl and add eggs, whisking to break up, then add yogurt and vanilla. Whisk to combine into a batter (you might see some small specks of butter; that's okay). Scrape about three-quarters of batter into prepared pan, then whisk cocoa into remaining batter. Dollop evenly over top and swirl with a toothpick or skewer.
• Return reserved flour-butter mixture to bowl and stir in hazelnuts until a granola-like mixture forms. Sprinkle over top of batter in pan, squeezing to create clumps. Bake until top of cake springs back when lightly pressed, about 45 minutes. Let cool in pan 10 minutes.
• Using overhangs, lift out of pan and transfer to a wire rack; let cool completely. Cut into 12 squares. Cake can be stored in an airtight container at room temperature up to 2 days.
