Unsalted butter
Granulated sugar
Eggs
Vanilla extract
Unsweetened cocoa powder
All-purpose flour
Salt
Baking powder
Semisweet chocolate chips
Peppermint extract
Green food coloring (optional, for the mint layer)
Powdered sugar
Cream cheese or butter (for the mint layer)

Directions

Prepare the brownie base:
In a saucepan, melt the butter over low heat. Stir in the sugar, then remove from heat. Add eggs one at a time, whisking continuously, then mix in vanilla extract.
Add dry ingredients:
Stir in cocoa powder, flour, salt, and baking powder until fully combined. Fold in chocolate chips.
Bake the bottom layer:
Pour half the brownie batter into a greased baking dish and bake at 350°F (175°C) for 10–12 minutes until slightly set.
Make the mint filling:
While the base bakes, combine softened cream cheese or butter with powdered sugar, peppermint extract, and a drop or two of green food coloring. Beat until smooth and creamy.
Layer and finish baking:
Spread the mint layer evenly over the baked brownie base. Gently spoon the remaining brownie batter over the mint layer and smooth the top.
Final bake:
Return to oven and bake for another 25–30 minutes, or until a toothpick comes out with just a few moist crumbs.
Cool and serve:
Let cool completely before slicing into squares. Optionally garnish with fresh mint leaves for presentation.

FAQs

What type of chocolate works best for brownies?

Semisweet or dark chocolate works best for a rich, balanced flavor. Avoid milk chocolate as it may make the brownies overly sweet.

Can I use peppermint oil instead of peppermint extract?

Yes, but use it sparingly. Peppermint oil is much more concentrated than extract. Use about ¼ teaspoon for the same effect.

Should I refrigerate the brownies before slicing?

Yes, chilling the brownies helps firm the layers and makes for cleaner, neater cuts.

Can I skip the food coloring?

Absolutely. The green coloring is just for appearance and does not affect flavor.

Can I use a brownie mix instead of making them from scratch?

Yes, you can use your favorite brownie mix for the base and top layer, then prepare the mint filling separately.

How do I know when the brownies are done?

Insert a toothpick into the center; if it comes out with a few moist crumbs (not raw batter), they’re ready.

Can I double the recipe?

Yes, just use a larger baking dish and adjust the baking time as needed.

What size pan should I use?

An 8×8 or 9×9 inch square pan is ideal for this recipe.

Can I add chocolate ganache on top?

Yes, a thin layer of ganache on top adds a luxurious finish. Let the brownies cool completely before spreading.

Are these good for holiday baking?

Definitely. The mint flavor and festive green color make them perfect for holiday dessert tables or cookie swaps.

Conclusion

Mint chocolate brownies are a delightful fusion of rich cocoa and refreshing peppermint, offering both visual appeal and indulgent flavor. Whether for festive gatherings or a unique dessert any time of year, these brownies are sure to leave a lasting impression.
