  • 15.25 oz chocolate fudge cake mix
  • 1 1/4 cup water
  • 1/2 cup vegetable oil
  • 3 eggs
  • 11.75 oz jar of hot fudge
  • 6 graham crackers
  • 7 oz jar marshmallow cream
  • 4 - 1.55 oz. chocolate bars, broken into pieces


  • Mix the chocolate fudge cake following the instructions on the box for oil, water and eggs.
  • Pour the chocolate fudge cake mix into a lightly greased 9 x 13" glass baking dish. TIP: To help the cake cook evenly, run a strip of terrycloth from an old bath towel under cold water. Wrap it around the cake pan and secure it with a safety pin. This will keep the edges from cooking too quickly which causes the cake to mound up in the center.
  • Bake at 350 degrees for 30-35 minutes or until a toothpick comes out clean. Let the chocolate fudge cake cool for 15 minutes.
  • Use the end of a wooden spoon to poke holes in the cake about 1 inch apart.
  • Heat the jar of hot fudge in the microwave for 30 seconds. Stir, then heat for 20 more seconds. Pour 3/4 of the jar over the top of the holes in the cake.
  • Crush the graham crackers and sprinkle over top of the chocolate fudge cake. 
  • Spoon dollops of marshmallow cream across the chocolate fudge cake. 
  • Broil on high for 1-2 minutes or until the marshmallows are toasted. WATCH CLOSELY so the marshmallow doesn't burn. 
  • As soon as you take the chocolate fudge cake out of the oven, drizzle the remaining hot fudge across the top. Insert chocolate bar pieces into the toasted marshmallow. 
  • The warmth of the cake will cause the chocolate bars to melt slightly. Enjoy!
