Credited to BunnysWarmOven (10″ dutch oven, 350 oven, 1 ring and 3 extra coals on lid, 8 below)

Ingredients

• 1/2 cup butter, softened
• 3/4 cup sugar
• 1 egg
• 1 teaspoon vanilla extract
• 1 1/3 cups flour
• 3/4 cup graham cracker crumbs
• 1 teaspoon baking powder
• 1/4 teaspoon salt
• 4 (1 5/8 ounce) milk chocolate candy bars ( I use Hershey’s)
• 3 cups miniature marshmallows

Directions

1. Heat oven to 350ºF. Grease an 10 inch dutch oven or line with parchment.
2. Beat butter and sugar together until well blended in a large bowl. Add egg and vanilla; beat well.
3. In another bowl stir together flour, graham cracker crumbs, baking powder, and salt. Add to butter mixture, beating until blended.
4. Press half the dough into the prepared pan. Bake 15 minutes.
5. Unwrap chocolate bars; arrange over baked layer. They may not quite all fit, you may be forced to eat a couple pieces. Sprinkle with marshmallows. Scatter remaining dough over the marshmallows, forming a top layer.
6. You may want to remove the oven from the bottom heat and just let the hot lid and oven finish things. This may help in not burning the bottom layer.
7. Bake 10- 15 minutes or until just lightly browned. Cool completely before cutting.
