Ingredients
Method
- Whisk the flour, cocoa powder, salt, baking powder, and baking soda together and set aside.
- Cream the butter and both sugars until light and creamy, then beat in the egg and vanilla.
- Add the dry ingredients just until combined. Fold in the mini chocolate chips, marshmallows, and crumbled graham crackers.
- Refrigerate the dough at least 30 minutes.
- Scoop onto a lined baking sheet and bake at 350°F for 8 minutes, until the edges are set and the centers still look slightly underdone.
- Cool on a rack.
