CHOCOLATE CAKE RECIPE FROM SCRATCH RECIPES

Steps:

• grease bottom and sides of pan (I use 2 round 10inch pans or 1 9 by 13). preheat oven to 350 degrees. I would even suggest lining the bottom with parchment paper and then spraying.
• Combine flour,  cocoa, baking soda, baking powder, and salt. Set aside. 
• In a separate bowl beat butter for 30 seconds or so. slowly add sugar.
• Add eggs 1 at a time beating after each one. Beat in vanilla.
• Add dry ingredients beating after each addition.
• Add 1/2 of the milk, beat. Then add the other 1/2. Beat just until everything is combined nicely.
• Spread batter about into pans making them about 2/3 full. You may have remaining batter (I sometimes make a few cupcakes.)
• Bake for 30-35 minutes for round pans, 5 min longer or so for the 9 by 13 pan. Watch it though! a knife coming out clean from the center means it is done. NOTE: Many readers are finding they need to increase the baking time. This is probably due to the difference in ovens, pans, and elevation. Always go by the way the cake looks and if the cake is done in the center.

Steps:

• Preheat the oven to 350 degrees F. Butter two 8-inch x 2-inch round cake pans. Line with parchment paper, then butter and flour the pans.
• Sift the flour, sugar, cocoa, baking soda, baking powder, and salt into the bowl of an electric mixer fitted with a paddle attachment and mix on low speed until combined. In another bowl, combine the buttermilk, oil, eggs, and vanilla. With the mixer on low speed, slowly add the wet ingredients to the dry. With mixer still on low, add the coffee and stir just to combine, scraping the bottom of the bowl with a rubber spatula. Pour the batter into the prepared pans and bake for 35 to 40 minutes, until a cake tester comes out clean. Cool in the pans for 30 minutes, then turn them out onto a cooling rack and cool completely.
• Place 1 layer, flat side up, on a flat plate or cake pedestal. With a knife or offset spatula, spread the top with frosting. Place the second layer on top, rounded side up, and spread the frosting evenly on the top and sides of the cake.
• Chop the chocolate and place it in a heat-proof bowl set over a pan of simmering water. Stir until just melted and set aside until cooled to room temperature.
• In the bowl of an electric mixer fitted with a paddle attachment, beat the butter on medium-high speed until light yellow and fluffy, about 3 minutes. Add the egg yolk and vanilla and continue beating for 3 minutes. Turn the mixer to low, gradually add the confectioners' sugar, then beat at medium speed, scraping down the bowl as necessary, until smooth and creamy. Dissolve the coffee powder in 2 teaspoons of the hottest tap water. On low speed, add the chocolate and coffee to the butter mixture and mix until blended. Don't whip! Spread immediately on the cooled cake.
