- Add the Chocolate: Top with a layer of chocolate bars.
- Mix the Brownie Batter: In a large mixing bowl, whisk together the brownie mix, large eggs, oil, and water until smooth.
- Add Brownie Layer and Bake: Pour the batter over the chocolate bars, then bake until set.
- Add Marshmallow Layer: Remove the brownies from the oven, then top them with the marshmallows.

Notes
Storage Instructions
- Room temperature: Store brownies in an airtight container at room temperature for up to 2–3 days. Keep them covered well so the marshmallows stay soft.
- Refrigerator: For longer storage, refrigerate for up to 5 days. Let them come to room temperature before serving for the best texture.
- Freezer: Wrap tightly and store in a freezer-safe container for up to 2 months.
- To thaw: Let frozen brownies sit at room temperature for a few hours, or warm briefly in the microwave for a gooey, fresh-baked finish.
