Method
- Preheat oven to 350°F (175°C). Grease a 9-inch cast iron skillet or pie dish.
- In a large bowl, cream together softened butter, brown sugar, and granulated sugar until light and fluffy.
- Beat in the egg and vanilla extract until fully combined.
- In a separate bowl, whisk flour, graham cracker crumbs, baking soda, and salt. Gradually mix into the wet ingredients.
- Fold in 1 cup of chocolate chips. Press the dough evenly into the skillet.
- Top with remaining 0.5 cup chocolate chips. Bake for 15-18 minutes until edges are golden.
- Remove from oven and top immediately with marshmallows. Bake for another 2-4 minutes (or broil briefly) until marshmallows are toasted golden brown.
- Let cool for 10-15 minutes before slicing or scooping.
Notes
Watch the marshmallows closely when broiling as they can burn in seconds.
