Ingredients
- 1 18.3 oz box of brownie mix
- 1/4 cup graham cracker crumbs
- 1/2 cup water
- 1/2 cup oil
- 1 egg
- 1 cup semi-sweet chocolate chips
- 2 cups miniature marshmallows
Instructions
- Step 1: Preheat your oven to 350ºF. In a large bowl, combine the brownie mix, graham cracker crumbs, water, oil, and egg. Mix by hand for 1 minute until just combined.
- Step 2: Spread the brownie batter evenly into a nonstick pan or a pan sprayed with nonstick spray.
- Step 3: Bake the brownies for 22 to 25 minutes, or until a toothpick inserted about 2 inches from the edge comes out clean. Be careful not to overcook.
- Step 4: Remove the brownies from the oven and immediately switch the oven to broil. Sprinkle the marshmallows and chocolate chips evenly over the top.
- Step 5: Place the pan under the broiler, about 4 to 6 inches from the heat source, for about 1 minute or until the marshmallows are lightly browned. Watch closely to avoid burning.
- Step 6: Let the brownies cool before cutting into 36 bars. Serve and enjoy!
Tips & Variations
- To prevent overcooking, make sure the broiler rack is in position and preheated before removing the brownies from the oven. This allows a quick transition to broiling the topping without losing heat.
- Try adding chopped nuts or drizzle caramel over the top for extra flavor and texture.
- Miniature marshmallows melt best; avoid large marshmallows as they may not toast evenly.
Storage
Store cooled brownies in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for up to 1 week. Reheat gently in a microwave for 10-15 seconds to soften before serving, but avoid overheating to keep the marshmallows from becoming too chewy.

Ingredients
Brownie Base
- 1 18.3 oz box of brownie mix
- 1/4 cup graham cracker crumbs
- 1/2 cup water
- 1/2 cup oil
- 1 egg
Topping
- 1 cup semi-sweet chocolate chips
- 2 cups miniature marshmallows
Instructions
- Preheat Oven: Preheat your oven to 350ºF (175ºC) to prepare for baking the brownie base.
- Mix Brownie Batter: In a large bowl, combine the brownie mix, graham cracker crumbs, water, oil, and egg. Mix everything by hand for about 1 minute until smoothly blended.
- Spread Batter: Pour and spread the brownie batter evenly into a nonstick baking pan or a pan sprayed with nonstick spray.
- Bake Brownies: Bake in the preheated oven for 22 to 25 minutes, testing doneness by inserting a toothpick about 2 inches from the side of the pan – it should come out clean. Avoid overbaking to keep brownies fudgy.
- Prepare for Broiling: Once baked, remove the pan from the oven immediately. Turn the oven to broil mode and get ready to toast the topping.
- Add Toppings: Evenly sprinkle the chocolate chips and miniature marshmallows over the top of the warm brownies.
- Broil Toppings: Place the pan under the broiler rack set about 4 to 6 inches from the heat source. Broil for approximately 1 minute, or until the marshmallows are lightly browned and toasted. Watch closely to prevent burning.
- Cool and Serve: Allow the brownies to cool sufficiently before cutting into 36 bars for serving. This helps toppings set and bars slice cleanly.
Notes
- Do not overcook the brownies during initial baking to avoid dry, tough bars once broiled with toppings.
- Preheat the broiler rack to the proper height before switching to broil mode to ensure quick, even toasting without heat loss.
- Have the marshmallows and chocolate chips ready to sprinkle immediately when brownies come out of the oven to reduce waiting time and maintain optimal texture.
