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.)

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 dry ingredients until smooth.
- Step 4: Pour the batter into the prepared pan and bake for 25 minutes. Check with a toothpick for doneness.
- Step 5: Prepare the frosting by beating marshmallow fluff until fluffy and smooth.
- Step 6: Let the brownies cool completely, then spread the frosting evenly over the brownies.
- Step 7: Optionally, broil the frosted brownies for 1-2 minutes for a toasted finish.
- Step 8: Chill in the refrigerator for about an hour before slicing into squares.
Tips & Variations

- For extra crunch, sprinkle chopped nuts on top before adding the marshmallows.
- Try adding a pinch of cinnamon or espresso powder to the batter for a deeper flavor.
Storage
Store the brownies in an airtight container in the refrigerator for up to 5 days. Allow them to come to room temperature or warm slightly before serving for the best texture. The frosting may soften, so handle carefully when reheating.

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
Marshmallow Frosting and Topping
- 1 cup Marshmallow fluff
- 1 cup Mini marshmallows
Instructions
- Preheat the oven: Set your oven to 350°F (175°C) and grease or line an 8×8 inch baking pan to prevent sticking during baking.
- Mix dry ingredients: In a large bowl, sift together the unsweetened cocoa powder, all-purpose flour, and granulated sugar. Whisk this mixture until evenly combined to ensure no lumps.
- Prepare wet ingredients: In a separate bowl, melt the butter fully, then whisk in the room temperature eggs and vanilla extract until the mixture is smooth and emulsified.
- Combine batter: Pour the wet mixture into the dry ingredients and whisk until the batter is smooth and homogeneous without overmixing.
- Bake the brownies: Transfer the batter to the prepared pan and bake in the preheated oven for 25 minutes. Check doneness by inserting a toothpick; it should come out with a few moist crumbs but no raw batter.
- Make the frosting: While the brownies bake and cool, beat the marshmallow fluff using a mixer or whisk until it becomes light, fluffy, and smooth in texture.
- Frost the brownies: Once the brownies have cooled completely to room temperature, spread the marshmallow frosting evenly over the top to create a soft, sweet layer.
- Optional broil: Place the frosted brownies under the broiler for 1 to 2 minutes to toast the marshmallow frosting slightly. Watch carefully to avoid burning.
- Chill and serve: Refrigerate the brownies for about an hour to set the frosting and make slicing easier. Cut into squares and garnish with mini marshmallows on top before serving, if desired.
