How to Make Chocolate Fudge Sheet Cake

  1. Preheat oven to 350°F (175°C). Grease and flour an 8x11 inch baking pan.
  2. In a medium bowl, whisk together 2 cups all-purpose flour, 2 cups sugar, 1 teaspoon baking powder, 1 teaspoon baking soda, and 1/2 teaspoon salt.
  3. In a saucepan over medium heat, melt 1 cup (2 sticks) unsalted butter.
  4. Stir in 1 cup water and 1 cup unsweetened cocoa powder.
  5. Bring to a boil, stirring constantly. Boil for 2 minutes.
  6. Remove from heat and gradually stir in the dry ingredient mixture until smooth.
  7. Stir in 1 cup buttermilk, 2 large eggs, and 1 teaspoon vanilla extract.
  8. Pour batter into the prepared pan and spread evenly.
  9. Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean.
  10. While the cake is baking, prepare the icing:
  11. In a saucepan over medium heat, melt 1 cup (2 sticks) unsalted butter.
  12. Add 1/2 cup milk and 1 cup granulated sugar.
  13. Bring to a boil, stirring constantly. Boil for 2 minutes.
  14. Remove from heat and stir in 2 cups semi-sweet chocolate chips, 1 cup mini marshmallows, and 1/2 cup chopped nuts (optional).
  15. Stir until the chocolate chips and marshmallows are melted and the icing is thick.
  16. Pour the icing over the cooled cake and spread evenly.
  17. Let the icing set completely before cutting and serving.
