Chocolate Pumpkin Cake

INGREDIENTS
1 1/2 c. flour
c. cocoa
2 tsp. baking powder
1 tsp. baking soda
1/2 tsp. salt
1/2 c. Buttermilk
1 c. Canned pumpkin
2 tsp. vanilla extract
3/4 c. butter
1 c. dark brown sugar
1 c. granulated sugar
large eggs
egg yolk
 
DIRECTIONS
  1. Line the bottoms of two 8-inch cake pans with parchment paper and lightly butter.
  2. Sift the flour, cocoa, baking powder, baking soda, and salt together. Stir the buttermilk, pumpkin, and vanilla extract together in a small bowl. Beat the butter and sugars together using an electric mixer on medium speed until light and fluffy. Beat in the eggs and yolk, one at a time. Reduce mixer speed to low and alternately beat in the flour and buttermilk mixtures in thirds.
  3. Pour the batter into the prepared pans. Bake until a tester, inserted in the center, comes out clean–about 35 minutes. Cool layers completely before icing.
  4. Step 1: Frost Beat 6 ounces softened cream cheese using a mixer set on medium-high speed until fluffy. Add 1 1/2 cups confectioners’ sugar, 2 1/4 teaspoons cocoa, 1/4 teaspoon cinnamon, and 3/4 teaspoon vanilla and beat on low speed until well combined. In a separate bowl, beat 1 1/2 cups heavy cream with 3/4 cup confectioners’ sugar and a scant 1/4 teaspoon orange food coloring on medium-high to soft peaks. Gently fold the whipped cream into the cream cheese mixture until well combined. Spread 1 cup frosting between the two layers and use the remaining frosting to ice the top and sides of the cake. Chill 30 minutes and proceed to step 2. Makes 3 cups.
  5. Step 2: Glaze Place 4 ounces of chopped bittersweet chocolate, 1 tablespoon cold unsalted butter, and 3 tablespoons corn syrup in a medium heatproof bowl. Bring 1/2 cup heavy cream to a boil, pour it over the chocolate, and let sit for 3 minutes. Gently stir, using a whisk, until smooth. Let sit for 3 to 5 minutes, until the glaze thickens slightly. Pour the glaze onto the center of the frosted cake and smooth out to the edges to allow the glaze to drop over the sides. Makes 1 cup.
