Introduction

Ingredients
- 1/2 cup unsalted butter
- 4 ounces semisweet chocolate, chopped
- 1 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/4 cup cocoa powder
- 1 teaspoon instant coffee granules
- 1/2 cup all-purpose flour
- 1/4 teaspoon salt
- Cocoa powder (for dusting)
- Marshmallow Frosting:
- 1 cup marshmallow fluff
- 1/2 cup unsalted butter, softened
- 1 teaspoon vanilla extract
- Pinch of salt
- 1 cup powdered sugar
Instructions
- Step 1: Preheat the oven to 350°F (175°C). Grease and line an 8×8-inch baking pan with parchment paper.
- Step 2: In a microwave-safe bowl or double boiler, melt the butter and semisweet chocolate together until smooth. Allow it to cool slightly.
- Step 3: Whisk in the granulated sugar, eggs, and vanilla extract into the chocolate mixture until well combined.
- Step 4: In a separate bowl, whisk together the cocoa powder, instant coffee granules, flour, and salt. Gradually fold the dry mixture into the wet mixture until just combined.
- Step 5: Pour the batter into the prepared baking pan and smooth the top. Bake for 20-25 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. Let cool completely in the pan.
- Step 6: To make the marshmallow frosting, beat together marshmallow fluff, softened butter, vanilla extract, and a pinch of salt until smooth and creamy. Gradually add powdered sugar and continue beating until light and fluffy.
- Step 7: Once brownies are cool, spread the frosting evenly over the top, creating peaks with a spatula.
- Step 8: Dust the frosting with cocoa powder, slice into squares, and serve.
Tips & Variations
- For a richer chocolate flavor, use dark chocolate instead of semisweet.
- If you prefer a creamier frosting, add a tablespoon of cream cheese to the marshmallow frosting.
- Add chopped nuts or chocolate chips to the batter for extra texture.
- Instant coffee granules enhance the chocolate taste, but you can omit them if desired.
Storage
Store the brownies in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate them for up to a week. When refrigerated, allow the brownies to come to room temperature before serving for the best texture. Reheat gently if desired, but be cautious not to melt the marshmallow frosting.

- 1 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/4 cup cocoa powder
- 1 teaspoon instant coffee granules
- 1/2 cup all-purpose flour

Marshmallow Frosting
- 1 cup marshmallow fluff
- 1/2 cup unsalted butter, softened
- 1 teaspoon vanilla extract
- Pinch of salt
- 1 cup powdered sugar
Instructions
- Preheat Oven: Preheat the oven to 350°F (175°C). Grease and line an 8×8-inch baking pan with parchment paper to ensure easy removal of the brownies after baking.
- Melt Chocolate and Butter: In a microwave-safe bowl or using a double boiler, gently melt the unsalted butter and chopped semisweet chocolate together until smooth. Let the mixture cool slightly to avoid cooking the eggs in the next step.
- Mix Batter: Whisk the granulated sugar, eggs, and vanilla extract into the melted chocolate and butter mixture until well combined, creating a smooth and glossy batter.
- Add Dry Ingredients: In a separate bowl, whisk together the cocoa powder, instant coffee granules, all-purpose flour, and salt. Gradually fold this dry mixture into the wet chocolate mixture until just combined, taking care not to overmix for tender brownies.
- Bake Brownies: Pour the batter into the prepared baking pan and spread evenly. Bake in the preheated oven for 20 to 25 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. Let the brownies cool completely in the pan before frosting.
- Prepare Marshmallow Frosting: In a mixing bowl, beat together the marshmallow fluff, softened butter, vanilla extract, and a pinch of salt until smooth and creamy. Gradually incorporate the powdered sugar, continuing to beat until the frosting becomes light, fluffy, and spreadable.
- Frost Brownies: Once the brownies have fully cooled, spread the marshmallow frosting evenly over the top using a spatula, creating decorative peaks if desired.
- Garnish and Serve: Lightly dust the surface of the frosting with cocoa powder to add an elegant finishing touch. Slice the brownies into squares and serve immediately or store for later enjoyment.
Notes
- Ensure brownies are completely cool before frosting to prevent the marshmallow fluff from melting.
- If you prefer a stronger coffee flavor, you can increase the instant coffee granules to 1 1/2 teaspoons.
- These brownies can be stored in an airtight container at room temperature for up to 3 days or refrigerated for up to a week.
- For a gluten-free option, substitute all-purpose flour with an equal amount of gluten-free baking flour blend.
- Use parchment paper with an overhang on the pan for easy lifting of the entire brownie slab.
