Ingredients
- 12 graham crackers , full rectangles
- 2 cups flour
- 1 cup brown sugar
- 1/3 cup cocoa powder unsweetened
- 1 teaspoon baking powder
- 1 teaspoon baking soda
- 1/4 teaspoon salt
- 1 cup buttermilk
- 1/3 cup vegetable oil
- 2 large egg
- 1 teaspoon vanilla extract
- 1/3 cup semisweet chocolate chips
- 1 bag marshmallows 10 ounces, jumbo
Instructions
- Preheat oven to 350 degrees. Spray a 9x13 baking pan with baking spray.
- Line bottom of prepared baking pan with graham crackers.
- In a large bowl, sift together flour, brown sugar, cocoa, baking powder, baking soda, and salt.
- Add buttermilk, oil, eggs, and vanilla and whisk until just combined.
- Pour cake batter gently over the graham crackers in the pan.
- Bake for about 30-35 minutes, or until a toothpick inserted in the center comes out clean.
- Place marshmallows evenly over the top of the cake very carefully (baking pan is hot, it can burn you easily).
- Return cake to oven, and broil until marshmallows are just golden brown, about 30-45 seconds. Watch carefully because the marshmallows can burn quickly. You are not looking for the marshmallows to melt here, just slightly brown.
- Remove from oven and cool before serving.
- Microwave individual slices for about 15-20 seconds before serving to make the marshmallow topping gooey. You want to stop the microwave right when you start to see the marshmallow starting to inflate, if you wait to long the marshmallow topping will dry out.
