Ingredients

- 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.)

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 fudgy brownies, slightly underbake them and let them set while cooling.
- Use brown sugar instead of granulated sugar to add moisture and a hint of caramel flavor.
- Try dairy-free butter or coconut oil to make this recipe vegan-friendly.
- Add a pinch of espresso powder to the batter to deepen the chocolate flavor.
- Sprinkle mini chocolate chips on top of the marshmallow frosting before chilling for added texture.
Storage
Store the brownies in an airtight container in the refrigerator for up to 4 days. Bring them to room temperature before serving or enjoy chilled. If needed, warm individual pieces briefly in the microwave to soften the frosting.

FAQs
Can I use regular marshmallows instead of marshmallow fluff?
Marshmallow fluff is smoother and easier to spread, but you can melt regular marshmallows into a frosting by heating them gently with a little butter or cream. Just note the texture will be slightly different.
How do I know when the brownies are done baking?
Insert a toothpick into the center; it should come out with a few moist crumbs but not wet batter. Brownies continue to set as they cool, so avoid overbaking to keep them fudgy.

Ingredients
Brownie Base
- 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.)
Marshmallow Frosting and Garnish
- 1 cup Marshmallow fluff (Opt for store-bought for convenience.)
- 1 cup Mini marshmallows (Perfect for garnishing.)
Instructions
- Preheat Oven and Prepare Pan: Preheat your oven to 350°F (175°C). Grease or line an 8×8 inch baking pan with parchment paper to prevent sticking and ensure easy removal.
- Mix Dry Ingredients: In a large mixing bowl, sift together the unsweetened cocoa powder, all-purpose flour, and granulated sugar. Whisk thoroughly to blend evenly and break up any lumps.
- Combine Wet Ingredients: In a separate bowl, melt the butter until liquid and warm but not hot. Whisk in the eggs and vanilla extract until the mixture is smooth and homogeneous.
- Make the Batter: Pour the wet ingredients into the dry ingredients bowl and stir until just combined into a smooth batter, being careful not to overmix to maintain brownie texture.
- Bake the Brownies: Pour the batter into the prepared baking pan and spread evenly. Bake in the preheated oven for approximately 25 minutes. Insert a toothpick in the center to check doneness; it should come out with a few moist crumbs but not wet batter.
- Prepare the Marshmallow Frosting: While the brownies bake and cool, beat the marshmallow fluff using a mixer until it becomes light, fluffy, and smooth to spread easily.
- Cool and Frost: Allow the brownies to cool completely in the pan to prevent melting the frosting. Once cooled, spread the marshmallow fluff evenly over the surface.
- Optional Broil for Toasted Finish: For added flavor and a toasty marshmallow top, place the frosted brownies under the broiler for 1-2 minutes, watching carefully to avoid burning.
- Chill and Garnish: Chill the brownies in the refrigerator for about one hour to set the frosting. Just before serving, sprinkle mini marshmallows evenly over the top as a garnish and to add chewy texture.
Notes
- Use room temperature eggs for better batter incorporation and brownie texture.
- Substitute brown sugar for granulated sugar to add moistness and a slight caramel flavor.
- For a dairy-free option, replace butter with vegetable oil.
- Ensure brownies are fully cooled before frosting to prevent melting the marshmallow fluff.
- Watch the brownies closely while broiling as marshmallows can burn quickly.
- Store leftover brownies in an airtight container in the refrigerator for up to 3 days.
