Hot Chocolate Brownies with Marshmallow Frosting Recipe
Introduction
The aroma of rich chocolate brownies combined with sweet marshmallow frosting is irresistible. These Hot Chocolate Brownies with Marshmallow Frosting blissfully satisfy any sweet craving and bring a comforting, nostalgic feel perfect for cozy moments or celebrations.

Ingredients
- 1 cup Unsweetened cocoa powder (High-quality cocoa is key for the best results.)
- 1 cup All-purpose flour (Can substitute with gluten-free flour if needed.)
- 1 cup Granulated sugar (Brown sugar can be used for extra moistness.)
- 2 large Eggs (Room temperature eggs help achieve optimal texture.)
- 1/2 cup Butter (Can replace with vegetable oil for a dairy-free alternative.)
- 1 tbsp Vanilla extract (Pure vanilla extract enhances flavor.)
- 1 cup Marshmallow fluff (Opt for store-bought for convenience.)
- 1 cup Mini marshmallows (Perfect for garnishing.)
Instructions
- Step 1: Preheat your oven to 350°F (175°C) and grease or line an 8×8 inch baking pan.
- Step 2: In a large mixing bowl, sift together the cocoa powder, flour, and sugar. Whisk until well combined.
- Step 3: In a separate bowl, melt the butter, then whisk in the eggs and vanilla until smooth. Combine with the dry ingredients until smooth.
- Step 4: Pour the batter into the prepared pan and bake for 25 minutes. Check doneness with a toothpick—it should come out with a few moist crumbs but no raw batter.
- Step 5: Prepare the frosting by beating marshmallow fluff until fluffy and smooth.
- Step 6: Let the brownies cool completely, then spread the marshmallow frosting evenly over the top.
- Step 7: Optionally, broil the frosted brownies for 1-2 minutes to toast the marshmallow topping lightly. Watch closely to prevent burning.
- Step 8: Chill in the refrigerator for about an hour before slicing into squares to set the frosting.
Tips & Variations
- Use brown sugar instead of granulated sugar for a richer, moister brownie.
- For a dairy-free version, substitute butter with vegetable oil and ensure marshmallow fluff is vegan-friendly.
- Add a pinch of espresso powder to the batter to deepen the chocolate flavor.
- Sprinkle chopped nuts or chocolate chips on top before broiling for added texture.
Storage
Store brownies in an airtight container in the refrigerator for up to 5 days. Let them come to room temperature or warm slightly for a soft texture. You can freeze brownies without frosting for up to 3 months; thaw before adding marshmallow frosting.

FAQs
Can I use regular marshmallows instead of marshmallow fluff for the frosting?
Marshmallow fluff is smoother and easier to spread, but you can melt regular marshmallows with a little butter to create a similar frosting. Be sure to cool before spreading.
What is the best way to check if brownies are done?
Insert a toothpick into the center; it should come out with a few moist crumbs but no raw batter. This ensures fudgy brownies rather than cakey.

Ingredients
Brownie Batter
- 1 cup Unsweetened cocoa powder
- 1 cup All-purpose flour
- 1 cup Granulated sugar
- 2 large Eggs
- 1/2 cup Butter
- 1 tbsp Vanilla extract
Frosting and Topping
- 1 cup Marshmallow fluff
- 1 cup Mini marshmallows
Instructions
- Preheat Oven and Prepare Pan: Preheat your oven to 350°F (175°C) and grease or line an 8×8 inch baking pan with parchment paper or foil for easy removal.
- Mix Dry Ingredients: In a large mixing bowl, sift together the cocoa powder, all-purpose flour, and granulated sugar. Whisk until thoroughly combined to ensure even distribution of ingredients.
- Combine Wet Ingredients: In a separate bowl, melt the butter until just liquefied. Whisk in the eggs and vanilla extract until the mixture is smooth and homogenous.
- Make the Batter: Pour the wet ingredients into the bowl of dry ingredients. Mix gently but thoroughly with a spatula or spoon until the batter is smooth and no lumps remain.
- Bake the Brownies: Pour the batter evenly into the prepared pan. Bake in the preheated oven for approximately 25 minutes. Insert a toothpick in the center; if it comes out with only moist crumbs, the brownies are done.
- Prepare Marshmallow Frosting: While the brownies bake, beat the marshmallow fluff in a bowl until it is fluffy and smooth, making it easier to spread.
- Cool and Frost: Allow the brownies to cool completely on a wire rack before spreading the marshmallow fluff evenly on top to prevent melting and slipping.
- Toast the Frosting (Optional): Place the frosted brownies under the broiler for 1 to 2 minutes until the marshmallow topping is lightly toasted and browned. Watch carefully to prevent burning.
- Chill and Serve: Chill the brownies in the refrigerator for about an hour to set the frosting. Slice into squares and garnish with mini marshmallows if desired for extra texture and presentation.
