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 extract until smooth. Combine this wet mixture with the dry ingredients and mix until smooth.
Step 4: Pour the batter into the prepared pan and bake for about 25 minutes. Test doneness by inserting a toothpick into the center; it should come out with a few moist crumbs.
Step 5: Prepare the frosting by beating the marshmallow fluff until fluffy and smooth.
Step 6: Let the brownies cool completely in the pan. Once cooled, spread the marshmallow frosting evenly over the brownies.
Step 7: Optionally, place the frosted brownies under the broiler for 1–2 minutes to toast the marshmallow topping lightly. Watch carefully to avoid burning.
Step 8: Chill the brownies in the refrigerator for about an hour to set the frosting before slicing into squares and garnishing with mini marshmallows.

Tips & Variations

For a dairy-free version, substitute the butter with vegetable oil and ensure marshmallow fluff is vegan-friendly.
Using brown sugar instead of granulated sugar adds extra moisture and a hint of caramel flavor.
To make the topping even more decadent, sprinkle chopped chocolate or toasted nuts along with the mini marshmallows.
If you prefer a stronger chocolate taste, increase cocoa powder by 2 tablespoons and slightly reduce flour.

Storage

Store the brownies covered in an airtight container at room temperature for up to 2 days, or refrigerate for up to 5 days. For best texture, allow refrigerated brownies to come to room temperature before serving. Reheating under a low broiler briefly can help revive the toasted marshmallow flavor.

How to Serve

Serve this delicious recipe with your favorite sides.

FAQs

Can I use a different size pan?

Yes, but baking time will vary. A larger pan will yield thinner brownies and require less baking time, while a smaller pan will produce thicker brownies and may need more baking time. Check doneness frequently to avoid overbaking.

Can I make the brownies ahead of time?

Absolutely. You can bake the brownies and keep them refrigerated without frosting for up to 2 days. Add the marshmallow frosting and toppings just before serving to maintain freshness and texture.

Ingredients

Scale

Brownie Batter

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.)

Frosting & Topping

1 cup Marshmallow fluff (Opt for store-bought for convenience.)
1 cup Mini marshmallows (Perfect for garnishing.)

Instructions

Preheat and Prepare Pan: Preheat your oven to 350°F (175°C) and grease or line an 8×8 inch baking pan with parchment paper to prevent sticking and ensure easy removal of the brownies.
Mix Dry Ingredients: In a large mixing bowl, sift together the unsweetened cocoa powder, all-purpose flour, and granulated sugar to combine evenly and remove any lumps. Whisk the mixture until well incorporated.
Combine Wet Ingredients: In a separate bowl, melt the butter until liquid. Add the room temperature eggs and vanilla extract, then whisk vigorously until the mixture is smooth and homogeneous.
Form Batter: Pour the wet ingredient mixture into the bowl with the dry ingredients. Stir gently until the batter is smooth and no dry spots remain, being careful not to overmix to maintain a tender texture.
Bake Brownies: Pour the batter into the prepared baking pan, smoothing the top with a spatula. Bake in the preheated oven for 25 minutes. Test doneness by inserting a toothpick into the center; it should come out with a few moist crumbs but not wet batter.
Prepare Frosting: While the brownies bake, beat the marshmallow fluff with a spoon or mixer until it is light, fluffy, and smooth for easy spreading.
Cool Brownies: Remove the brownies from the oven and allow them to cool completely in the pan to room temperature, ensuring the frosting does not melt upon application.
Frost Brownies: Evenly spread the marshmallow fluff over the cooled brownies, covering the surface entirely for a creamy layer.
Optional Toasted Finish: For a toasted marshmallow effect, place the frosted brownies under the oven broiler for 1 to 2 minutes. Watch closely to avoid burning; the marshmallows should be golden brown and toasted.
Chill and Serve: Refrigerate the brownies for about an hour to set the frosting. Once chilled, cut into squares and serve for a delightful treat.

Notes

Using room temperature eggs helps the batter mix uniformly and prevents curdling.
Substitute vegetable oil for butter to make this recipe dairy-free.
Brown sugar can replace granulated sugar to add extra moisture and a slight caramel flavor.
Watch closely during broiling the frosting to prevent it from burning, as marshmallows toast quickly.
For gluten-free option, use a 1:1 gluten-free flour blend instead of all-purpose flour.
Store leftovers in an airtight container in the refrigerator for up to 5 days.
