Ingredients

  • 1/2 cup butter, softened
  • 2 cups packed brown sugar
  • 2 egg yolks
  • 2 teaspoons vanilla extract
  • 6 ounces semisweet chocolate, melted and cooled
  • 1 cup cold strong brewed coffee
  • 3 cups all-purpose flour
  • 1-1/2 teaspoons salt
  • 1-1/2 teaspoons baking soda
  • 1 cup buttermilk
  • 2/3 cup sugar
  • 1/2 cup milk
  • 1/4 cup butter, cubed
  • 1 teaspoon rum extract
  • 1 cup (6 ounces) semisweet chocolate chips
  • 1/4 cup milk
  • 1 carton (8 ounces) frozen whipped topping, thawed
  • Chocolate curls

Method

  • Line two greased 9-in. round baking pans with waxed paper and grease the paper; set aside. In a large bowl, beat butter and brown sugar until crumbly. Beat in egg yolks and vanilla. Stir in chocolate and coffee. Combine flour, salt and baking soda; gradually add to chocolate mixture alternately with buttermilk (batter will be thick).
  • Pour into prepared pans. Bake at 350° for 25-30 minutes or until a toothpick inserted in the center comes out clean. Cool for 10 minutes.
  • Meanwhile, in a small saucepan, bring sugar, milk and butter to a gentle boil; cook and stir for 2 minutes or until sugar is dissolved. Remove from the heat; stir in extract.
  • Invert cakes onto wire racks; drizzle with glaze. Cool completely. In a microwave, melt chocolate chips and milk; stir until smooth. Refrigerate until spreadable, stirring occasionally.
  • Place one cake on a serving plate; spread with filling. Top with remaining cake. Spread whipped topping over top and sides of cake. Store in the refrigerator. Garnish with chocolate curls.
