Mint Fudge Stuffed Brownies

Friday afternoons in our town always have a certain rhythm. Kids pour out of school with backpacks half open, the grocery store hums with people grabbing last minute plans, and I usually clock out thinking about what might make the evening feel special without turning it into extra work.

On one of those afternoons, a neighbor mentioned her son’s school fundraiser, another friend talked about a movie night with teenagers sprawled on the living room floor, and suddenly dessert felt like more than just dessert.

That evening, the kitchen wasn’t quiet. Homework papers were spread across the table, my youngest was asking about mint chocolate ice cream, and my husband was flipping through the mail.

I had brownie batter in mind, but not the plain pan I’d made dozens of times. I wanted a little surprise in the middle, something that would feel playful and just indulgent enough for the end of a long week.

Mint fudge entered the picture almost by accident. A jar of chocolate fudge sauce sat on the counter, peppermint extract from holiday baking peeked out of the cabinet, and the idea came together quickly. Thick brownies with a hidden minty center sounded like the kind of treat that would disappear fast, shared between kids, neighbors, and whoever happened to stop by. By the time they cooled, the kitchen smelled rich and chocolatey, and the night felt exactly how I’d hoped it would.

Short Description

Mint Fudge Stuffed Brownies are rich chocolate brownies with a soft, fudgy mint center baked right inside. They balance deep cocoa flavor with a clean peppermint finish, perfect for family desserts, gatherings, or make ahead treats.

Key Ingredients

• 1 cup unsalted butter, melted
• 1 ½ cups granulated sugar
• ½ cup light brown sugar
• 3 large eggs
• 1 teaspoon vanilla extract
• 1 cup all purpose flour
• ¾ cup unsweetened cocoa powder
• ½ teaspoon salt

Mint Fudge Filling

• 1 cup chocolate fudge sauce or chocolate ganache
• ½ teaspoon peppermint extract

Optional Topping

• Chocolate chips or chopped Andes mints

Tools Needed

• 8×8 inch baking pan
• Parchment paper
• Large mixing bowl
• Whisk
• Rubber spatula
• Measuring cups and spoons

Cooking Instructions

Step 1: Prepare the Oven and Pan.
Preheat the oven to 350°F or 175°C. Line an 8×8 inch baking pan with parchment paper, making sure to leave some overhang on the sides.

This overhang will help you lift the brownies out easily once they are fully cooled and also prevents sticking along the edges.

Step 2: Mix the Brownie Base.
In a large mixing bowl, whisk together the melted butter, granulated sugar, and light brown sugar until the mixture becomes smooth and glossy.

Add the eggs one at a time, mixing well after each addition so they incorporate evenly. Stir in the vanilla extract until fully blended.

Step 3: Add the Dry Ingredients.
Sprinkle the flour, cocoa powder, and salt over the wet mixture. Using a spatula, gently fold everything together just until no dry streaks remain.

The batter should look thick and silky. Stop mixing as soon as it comes together to avoid overworking the batter, which can make the brownies dense.

Step 4: Make the Mint Fudge Filling.
In a small bowl, combine the chocolate fudge sauce with the peppermint extract. Stir until smooth and evenly mixed. If you prefer a slightly stronger mint flavor, add an extra drop of peppermint extract, tasting as you go.

Step 5: Assemble the Brownies.
Spread half of the brownie batter evenly into the prepared pan. Spoon the mint fudge filling over the batter, spreading it gently while leaving a small border around the edges to prevent leaking.

Carefully add the remaining brownie batter on top, smoothing it out without disturbing the filling layer.

Step 6: Bake.
Place the pan in the center of the oven and bake for 30 to 35 minutes. The edges should appear set and slightly pulled away from the sides of the pan, while the center stays a bit soft and fudgy. A toothpick inserted near the edge should come out with a few moist crumbs attached.

Step 7: Cool and Finish.
Allow the brownies to cool completely in the pan. Once cooled, lift them out using the parchment paper overhang.

If desired, sprinkle chocolate chips or chopped Andes mints over the top, then slice into squares and serve.

FAQs

Yes. Prepare the mix according to package directions, then follow the same layering and baking steps.
