Starbucks Chocolate Fudge Squares with Mocha Glaze

Contributed by: Chris WebAdmin. of


  • 1/2 cup unsalted butter, at room temperature
  • 1 cup granulated sugar
  • 1 extra-large egg
  • 1 cup all-purpose flour
  • 1/4 teaspoon baking powder
  • 2 ounces unsweetened chocolate, melted
  • 1/2 cup milk
  • 1 teaspoon vanilla extract
  • 1/2 cup chopped walnuts

For the glaze:

  • 1 generous cup confectioners sugar
  • 1 tablespoon unsalted butter, at room temperature
  • 1 ounce unsweetened chocolate, melted
  • 1 teaspoon vanilla extract
  • 1/4 cup Starbucks Christmas or other dark roast coffee brewed double-strength


Preheat oven to 350 F. Butter an 8-inch-square baking pan.

To make the squares, in a large bowl, cream the butter with the sugar and egg.

In a small bowl, sift together the flour and baking powder. Add to the butter mixture. Then add the melted chocolate, being careful not to overbeat. Add the milk, vanilla and walnuts, stirring just to blend.

Pour the batter into the prepared pan. Bake until the edges begin to pull away from the sides of the pan and the top springs back when pressed lightly, about 30 minutes. Allow the cake to cool completely.

Meanwhile, to make the glaze, in a medium bowl, combine the sugar, butter, chocolate and vanilla. Stir in the coffee and whisk until smooth.

Refrigerate the glaze until cool, then pour over the top of the cake and cut the cake into squares.
