Instructions to Bake the Sweettooth Marshmallow Brownie
Warm up your kitchen and grab a baking pan. Choose between a cozy 9×9 or a larger 9×13 inch pan depending on how thick you want your dessert. Lightly coat the pan with cooking spray or line it with parchment paper.
Open your favorite brownie mix and follow the package guidelines. Pour the rich, chocolatey batter into your prepared pan. Slide the pan into a preheated oven set at 350 degrees. Bake until the edges look set but the center remains slightly soft.
Once the brownies look almost done, pull them out of the oven. Sprinkle fluffy marshmallows across the surface, creating a cloud-like topping that covers every inch. Return the pan to the oven for a quick 3-minute dance, allowing the marshmallows to puff up and turn golden.
While the brownies cool, whip up a creamy chocolate frosting. Blend softened butter with powdered sugar, cocoa powder, a splash of milk, and a hint of vanilla. Mix until the frosting becomes smooth and spreadable. Once the marshmallow layer has settled, dollop the frosting across the top and gently spread it into a delicious blanket.

Gooey Sweettooth Marshmallow Brownie Delight Recipe
- Total Time: 43 minutes
- Yield: 13 1x
Description
Homemade sweettooth marshmallow brownie delight blends rich chocolate with pillowy marshmallow layers. Dense chocolate base and gooey topping create perfect dessert harmony for serious chocolate enthusiasts.
Ingredients
- 1 box (18 oz or 510 g) brownie mix
- 2 cups mini marshmallows
- Eggs (as specified on box)
- Water (as specified on box)
- Vegetable oil (as specified on box)
- ¼ cup (56 g or 4 tbsps) salted butter, softened
- 1 ½ cups powdered sugar
- 2 tbsps unsweetened cocoa powder
- 2 tbsps milk
- ½ tsp vanilla extract
Instructions
- Preheating: Position the oven rack centrally and warm to 350ºF, creating an ideal baking environment for rich chocolate treats.
- Pan Preparation: Select either a 9×9″ or 9×13″ pan, generously coating with non-stick spray or lining with parchment paper to ensure effortless removal.
- Batter Creation: Combine brownie mix according to package guidance, whisking until a velvety, uniform chocolate mixture emerges with no lingering dry pockets.
- Initial Baking: Transfer the batter into the prepared pan, smoothing the surface carefully, then bake for approximately 30 minutes until the chocolate base reaches a moist, fudgy consistency.
- Marshmallow Transformation: Extract the partially baked brownies and liberally distribute marshmallows across the entire surface, ensuring complete coverage for a decadent layer of pillowy sweetness.
- Marshmallow Finish: Return to the oven for an additional 3 minutes, allowing marshmallows to puff and caramelize into a golden, tempting landscape.
- Frosting Fusion: While brownies cool, craft the chocolate frosting by blending butter, powdered sugar, cocoa powder, milk, and vanilla using electric beaters until achieving a silky, glossy texture.
- Final Assembly: Once brownies have completely cooled, strategically spread the luxurious frosting over the marshmallow layer, creating an indulgent, smooth topping that promises pure chocolate ecstasy.
Notes
- Select the Right Pan Size: Choose between 9×9″ for thick, decadent brownies or 9×13″ for thinner treats, matching your texture preference and crowd size.
- Master Marshmallow Placement: Scatter marshmallows evenly and completely across the partially baked brownies to ensure perfect golden-brown coverage and gooey texture.
- Prevent Overbaking: Watch brownies closely during baking, removing them when a toothpick comes out with a few moist crumbs to maintain that irresistible fudgy center.
- Frosting Consistency Tip: Adjust frosting thickness by adding small amounts of milk or powdered sugar until you achieve a smooth, spreadable consistency that glides effortlessly over the marshmallow layer.
