Every time I take these squares to a potluck, my pan comes back clean. At home, they vanish as fast as I make them. —Clarice Baker, Stromsburg, Nebraska

Ingredients

  • 1 cup butter, cubed
  • 1/4 cup baking cocoa
  • 1 cup water
  • 2 cups all-purpose flour
  • 2 cups sugar
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/2 cup buttermilk
  • 2 large eggs, room temperature, beaten
  • 1 teaspoon vanilla extract
  • 3 to 4 drops red food coloring, optional
  • FROSTING:
  • 1/2 cup butter, cubed
  • 1/4 cup baking cocoa
  • 1/4 cup buttermilk
  • 3-3/4 cups confectioners' sugar
  • 1 teaspoon vanilla extract
  • Dash salt
  • 3/4 cup chopped almonds, optional

Directions

  1. In a large saucepan, bring butter, cocoa and water just to a boil. Cool.
  2. Meanwhile, preheat oven to 350°. In a large bowl, combine the flour, sugar, baking soda and salt. Add cocoa mixture and buttermilk; mix well. Beat in the eggs, vanilla and, if desired, food coloring. Pour into a greased and floured 15x10x1-in. baking pan.
  3. Bake until set, 20 minutes. For frosting, melt butter with cocoa and buttermilk. Stir in the confectioners' sugar, vanilla and salt. Spread over warm cake. Garnish with nuts if desired.

Test Kitchen Tips
  • A warped 15x10x1 can produce uneven cakes. Make sure your pan's on the straight and narrow!
  • For different flavor thrills, try substituting almond, rum or mint extract for the vanillas. (Mint packs a punch—reduce it from 1 tsp. to 1/4 tsp.)
  • Brickle bits or other crushed candy bars are also delicious sprinkled over these gooey bars. Yum!
  • buttermilk
    To substitute for each cup of buttermilk, use 1 Tbsp. white vinegar or lemon juice plus enough milk to measure 1 cup. Stir, then let stand 5 min. Or, use 1 cup plain yogurt or 1-3/4 teaspoon cream of tartar plus 1 cup milk.
