Fluffy Coffee And Walnut Cake With Mocha Buttercream Recipes

Steps:

• In a small bowl, combine the first five ingredients; set aside. In a large bowl, cream butter and sugar until light and fluffy. Add eggs, one at a time, beating well after each addition. Beat in vanilla. Combine the flour, baking powder and baking soda; add to creamed mixture alternately with sour cream just until combined. Stir in chocolate chips., Pour a third of the batter into a greased 10-in. fluted tube pan. Sprinkle with half of the walnut mixture; repeat layers. Top with remaining batter. , Bake at 350° for 40-45 minutes or until a toothpick inserted in the center comes out clean. Cool for 10 minutes before removing to a wire rack. Dust with confectioners' sugar if desired.

Steps:

• Heat oven to 350 degrees. Butter two 8-inch cake pans, and line base of each with parchment paper. In food processor, combine 1/2 cup walnut pieces and sugar. Process to a fine powder. Add butter, flour, baking powder, salt and eggs. Process to a smooth batter.
• Add 2 tablespoons milk to coffee mixture and pour this down feed tube with motor running. Mixture should be just soft enough to drop from a spoon; if not, add more milk. Divide cake batter between two pans. Bake until risen and springy to touch, about 25 minutes. Cool on a rack for 10 minutes, then remove from pan and place on rack. Remove parchment paper. Cool completely. You may want to level them if they domed in the oven.
• For frosting: Place confectioners' sugar and salt in food processor and pulse until lump-free. Add butter and process until smooth. Add coffee mixture down feed tube and pulse until well blended.
• Place one cake upside down on a plate or cake stand. Spread with about half the frosting. Place second cake right side up on frosting, and cover top and sides in a swirly pattern. Place a walnut half in center of cake, and gently press remaining halves into top of cake, around the edge.

Steps:

• Bring 1 3/4 cups sugar and water to a boil in a 3-quart heavy saucepan over medium heat, stirring until sugar has dissolved, then wash down any sugar crystals from side of pan with a pastry brush dipped in cold water. Boil, without stirring, until it registers 220 to 225°F, 15 to 20 minutes.
• At this point, while continuing to boil syrup, beat whites with espresso powder, vanilla, cream of tartar, and salt in mixer at medium speed until they just hold soft peaks. Add remaining 1/4 cup sugar, 1 tablespoon at a time, beating, and beat until whites just hold stiff peaks.
• When syrup reaches soft-ball stage (238 to 242°F), immediately pour syrup in a slow stream down side of bowl into whites (avoid beaters) while beating at high speed. Beat until completely cool, 25 to 30 minutes. With mixer at medium speed, add butter 1 tablespoon at a time, beating well after each addition (see cooks' note, below) and until buttercream is smooth. (Mixture may look curdled before all butter is added but will come together at end.)
• Transfer 2 cups buttercream to a small bowl and stir in chocolate. If buttercreams are too soft to spread, chill, stirring occasionally.
