Chocolate Marshmallow Cake

NOTE: This is an older version of this recipe, made in a 9×13 pan.
Classic Texas Sheet Cake
I like this made as a sheet cake because the cake-to-frosting ratio is a little better.

But if you prefer the old version, I’ll leave the recipe here for you šŸ™‚

Looking back it would seem that I simply loved this cake because there were mounds marshmallows on top. Every kid likes a mallow, right? But now as an adult, I realize that’s exactly why I love it. Life really is that simple. Chocolate, Marshmallows, Cake. YUM.
The cake itself is moist, uber chocolatey, and delicious. Then pair that with slightly melted marshmallows? Down right dreamy.

Chocolate Marshmallow Texas Sheet Cake recipe

I cup boiling water
2 cups sugar
1 3/4 cups flour
3/4 cup cocoa powder
2 tsp baking soda
1 tsp baking powder
1 tsp salt
2 eggs
1 cup buttermilk (or use 1 cup milk mixed with 1 Tbl vinegar)
1/2 cup oil
1 tsp vanilla
Chocolate Satin Frosting (see recipe below)

1. Heat the oven to 350 degrees and grease a 13×9 pan.
2. Bring some water to boil and keep it simmering while you make the batter.
3. In a large mixing bowl, combine the sugar, flour, cocoa, baking soda, baking powder, and salt. Add the eggs, buttermilk, oil and vanilla and beat with an electric mixer for 30 seconds.
4. Add the 1 cup boiling water and carefully stir until the water is mixed in; beat for 1 1/2 minutes.
5. Pour the batter into the 13×9 pan (batter will be thin).
6. Bake at 350 for 35-38 minutes or just until the top springs back when lightly touched.
7. Make the frosting while the cake is baking. When the cake is done, pour the warm frosting over the hot cake.

1/2 cup butter
6 Tbl buttermilk (or use 6 Tbl milk mixed with 1 tsp vinegar)
4 Tbl cocoa powder
1 (16 oz) box powdered sugar
1 tsp vanilla
2 cups marshmallows (optional)

1. In a medium saucepan, combine the butter, buttermilk and cocoa. Cook, stirring constantly, just until it comes to a boil; remove the pan from the heat.
2. Add the powdered sugar and vanilla, and beat with a wooden spoon or electric mixer until the frosting is nearly smooth (stir every few minutes while the cake finished baking).
3. Add the marshmallows, then pour the warm frosting over the hot cake, gently spreading until it covers the cake evenly. Cool to room temperature before serving.

    I am assuming that you use plain flour since putting baking powder and soda in it right?
