Ingredients
Units
Scale
- 1 cup (2 sticks) unsalted butter, room temperature
- 1 cup granulated sugar
- 1 cup packed brown sugar
- 2 large eggs
- 2 tsp vanilla extract
- 2 3/4 cups all‑purpose flour
- 1 tsp baking soda
- 1/2 tsp salt
- 1 1/2 cups semisweet chocolate chips
- 2 cups mini marshmallows
- 1 cup chopped graham crackers (about 8-10 sheets)
- 1/2 cup milk chocolate chunks (optional extra)
Instructions
- Preheat oven to 350°F (175°C). Line a 9×13‑inch baking pan with parchment, leaving an overhang.
- In a large bowl, cream butter with granulated and brown sugars until light and fluffy, about 2–3 minutes.
- Add eggs one at a time, beating well after each, then stir in vanilla.
- Whisk flour, baking soda, and salt; gradually add to butter mixture until just combined.
- Fold in chocolate chips and graham cracker pieces.
- Press half the dough into the bottom of the prepared pan, creating an even base.
- Sprinkle mini marshmallows evenly over the dough, then top with the remaining dough (drop by spoonfuls and press gently to cover marshmallows).
- If using, sprinkle milk chocolate chunks over the top.
- Bake 25–30 minutes, until edges are golden and center is set but slightly soft.
- Let cool completely in pan on a wire rack (about 1 hour). Use parchment overhang to lift bars out, then cut into squares.
- Store airtight at room temperature up to 3 days or freeze for longer storage.
Notes
- For extra gooeyness, press a few extra marshmallows into the surface immediately after baking.
- Substitute dark chocolate chips or white chocolate for a different flavor.
- To make smaller bars, use a 9×9‑inch pan and reduce bake time by 5 minutes.
- Bars are best after cooling fully—cutting too soon makes them too soft.
- Freeze individual squares on parchment, then store in freezer bags for easy grab‑and‑go treats.
