How to Make the Mint Chocolate Brownies

Step 1 : Bake the Brownies

Melt your butter and chocolate together until smooth and glossy. Stir in the sugars, then the eggs one at a time. Add vanilla, then gently fold in flour, cocoa powder, and salt. Pour into a parchment-lined 9×13 pan and bake at 350°F for about 35 minutes. Let them cool completely (I know, the waiting is hard).

Step 2 : Make the Mint Frosting

Beat butter until creamy, then mix in the powdered sugar and milk. Add peppermint extract and a tiny drop of green food coloring if you’d like that retro minty vibe. Once the brownies are cool, spread this over the top and pop the pan into the fridge so it firms up, at least an hour.

Step 3 : Finish with Chocolate Ganache

Melt butter and chocolate chips together until silky smooth. Pour over the mint layer and gently spread it out. Back into the fridge it goes, until everything is set and sliceable. (This is when I start counting down.)

Step 4 : Slice and Serve

Once chilled, slice into squares with a sharp knife (wipe between cuts for that bakery-perfect look). And just like that, you’re the brownie queen.

Pro Tips for Making the Classic Mint Chocolate Brownies

• Don’t skip the chill time, It makes slicing a breeze and keeps those pretty layers intact.
• Taste the frosting before adding more mint, A little extract goes a long way.
• Use a sharp knife and clean between cuts, Especially if you want to impress with those crisp edges.
• Want to level up?, Add a tiny sprinkle of flaky salt on top of the chocolate layer. Just trust me.

How to Serve

I love serving these straight from the fridge, cool, firm, and totally decadent. They’re amazing on their own, but if you want to go all out, pair them with a scoop of vanilla ice cream or a peppermint mocha on the side. Perfect for holiday trays, birthdays, or a random Tuesday that needs a little joy.

Make Ahead and Storage

Storing Leftovers

Keep them in an airtight container in the fridge for up to 5 days. Though I doubt they’ll last that long.

Freezing

Yes, you can freeze them! I recommend doing it after the ganache has set. Wrap tightly and freeze up to 2 months. Thaw in the fridge overnight.

Reheating

No need! These brownies are best enjoyed chilled or at room temp. Just take them out a few minutes before serving if you want that perfect melt-in-your-mouth texture.

FAQs

Can I make these ahead of time?

Totally! In fact, I recommend it. They slice better and taste even more amazing after a good chill in the fridge.

Can I freeze them?

Yup! Freeze the whole batch or individual squares once the chocolate layer has set. They thaw beautifully in the fridge.

Can I use store-bought whipped cream instead of frosting?

I wouldn’t swap it here, whipped cream is too soft for this layered bar. The buttercream-style mint frosting gives structure and that classic flavor.

Can I add other flavors or fruits?

You could add a layer of raspberry jam under the mint frosting for a fun twist! But honestly, this mint-chocolate combo is a classic for a reason.

These Classic Mint Chocolate Brownies are everything I want in a dessert, comforting, a little indulgent, and totally shareable (if you’re feeling generous). They’ve got that perfect balance of richness and freshness, and once you’ve made them, I guarantee they’ll earn a permanent spot in your recipe box 💚

So go ahead, preheat that oven, and make something sweet for the people you love (yourself included).
