A few months ago Sister Tucker made a version of this for our Pathway class. It was so good. I thanked her and said, “It tastes like home.” She told me that was the best compliment.
Makes 24-30 pieces
1 3/4 cup flour
2 cups sugar
3/4 cup cocoa powder
2 tsp baking soda
1 tsp baking powder
1 tsp salt
1 cup buttermilk (or mix 1 cup of milk with 1 Tbl vinegar)*
1/2 cup oil
1 tsp vanilla
1 cup boiling water
• Heat the oven to 350 degrees.
• Grease a large jelly roll pan or cookie baking sheet.
• Bring 1 cup of water to boil in a small pan, or microwave it for about 3 minutes.
• In a large bowl, mix the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
• Add the buttermilk, eggs, oil, and vanilla and beat with an electric mixer for 30 seconds.
• Add 1 cup boiling water and carefully stir until the water is mixed in; beat for 1 1/2 minutes.
• Pour the batter into the prepared baking sheet and bake at 350 degrees for about 25 minutes, or until a toothpick comes clean from the center. Don’t under bake the cake! I’ve done it. It’s not as good as you’d think it would be.
While the cake is baking, prepare the frosting…
Chocolate Marshmallow Frosting
1 cup butter (2 sticks)
3/4 cup buttermilk (or mix 3/4 cup milk with 2 tsp vinegar)*
1/2 cup cocoa powder
2 tsp vanilla
32 oz bag of powdered sugar (about 8 cups)
5-6 cups marshmallows
• In a medium saucepan, combine the butter, buttermilk, and cocoa powder.
• Cook, stirring frequently, just until it comes to a boil. Then remove the pan from the heat.
• Pour the mixture into a clean bowl, add the vanilla and powdered sugar and beat with an electric mixer till smooth.
• Pour in the marshmallows and mix in with a spatula.
• Then pour the warm frosting over the hot cake when it comes out. THIS IS KEY. It’s best to frost while the cake is hot, so the marshmallows puff up slightly and become nice and gooey soft.
* I often use the milk and vinegar trick because who always keeps buttermilk in the refrigerator. It will turn out fine, but I think buttermilk just makes the cake and frosting so much better. It’s worth the trip to the store to get a quart!
