Decadent Chocolate Crepe Cake Recipes

Steps:

• Bring 1/4 cup water to a rolling boil in a small saucepan over medium-high heat. Add butter, 1 piece at a time, whisking to combine after each addition. Remove from heat; stir in chocolate until completely melted. Set aside.
• Whisk together flour, sugar, and salt in a medium bowl. Whisk together milk, eggs, and vanilla in another medium bowl. Gradually add milk mixture to flour mixture, whisking until smooth. Add chocolate-butter mixture, whisking until smooth. Pour through a fine sieve into an airtight container; discard lumps. Refrigerate at least 2 hours or up to overnight.
• Lightly coat an 8-inch crepe pan or nonstick skillet with melted butter. Heat over medium heat until just starting to smoke. Remove pan from heat; pour about 2 tablespoons batter into pan, swirling to cover bottom. Reduce heat to medium-low; return pan to heat. Cook, flipping once, until edges are golden and center is dry, about 30 seconds per side.
• Slide crepe onto a plate. Repeat process with remaining batter, coating pan with butter as needed. Crepes can be refrigerated, covered, up to 1 day.
• Place a crepe on a wire rack set over a rimmed baking sheet. Spread with about 3 tablespoons hazelnut filling. Top with another crepe. Continue layering with hazelnut filling and crepes, using about 32 crepes and ending with a crepe on top. Refrigerate until firm, about 15 minutes.
• Spoon 1/2 cup glaze on top of the cake, spreading to edges. Spread remaining glaze around sides of cake, coating completely. Refrigerate until glaze is firm and set, about 20 minutes. Cake can be refrigerated up to 3 days. Garnish with toasted and candied hazelnuts.

Steps:

• For the cake: Preheat the oven to 350 degrees F. Spray two 9-inch cake pans with nonstick cooking spray.
• Combine the flour, granulated sugar, cocoa powder, baking soda, baking powder and salt in the bowl of a stand mixer and mix on low until well combined (the mixture will be one uniform color). With the machine running on low, add the milk, boiling water, vegetable oil, vanilla and eggs. Mix on high, scraping down the sides as needed, until well combined and the mixture has air bubbles, about 1 minute.
• Divide the batter between the prepared cake pans and bake until a knife inserted in the center comes out clean, about 40 minutes. Let cool about 10 minutes in the pans. Run a thin knife around the edge of each cake, then invert the cakes onto a rack and let cool completely, 20 to 30 minutes.
• Using a serrated knife, cut a small portion from the top of each cake to completely flatten it. Save the trimmings for another use.
• For the frosting: When ready to assemble the cake, combine the powdered sugar and butter in a food processor and pulse until well combined. Add the chocolate and continue to pulse, scraping down the sides as needed. Add the sour cream and process until very smooth, about 1 minute.
• Place one cake layer on a platter and spread half of the frosting on top. Flip over the second cake layer, making sure the flattened side is facing the bottom, and place on top of the first cake layer. Spread the remaining frosting to cover only the top of the cake (leave the sides without frosting). Serve.

Steps:

• Preheat the oven to 350 degrees. Butter and flour a 10-inch round cake pan. For the cake: Melt the chocolate and butter in a double boiler (or in a bowl or smaller saucepan placed over a saucepan of boiling water). Set aside to cool. Beat the egg yolks until light and fluffy. Slowly add the sugar and continue beating until mixture is pale yellow. Fold in the melted chocolate. Sift the flour over the chocolate mixture until it just disappears. In a separate bowl, whisk the egg whites until soft peaks form. Fold egg whites into the chocolate mixture in 2 parts. Pour the batter into the prepared pan and tap on the counter to remove air bubbles. Bake for 20 to 25 minutes, until a toothpick comes out clean (see Cook's Note). For the ganache: Place the chopped chocolate in a mixing bowl. Place the cream in a saucepan and bring to a boil. Add the hot cream to the chocolate and stir until all lumps are gone. Let the ganache stand until it reaches room temperature, then pour it over the cooled cake and spread with a spatula.
