Oh boy, I think you’re going to love me and hate me for this easy Mint Brownies from scratch recipe! These brownies with mint frosting are sooo good that it may be hard to only have just one little one. Don’t say I didn’t warn you, haha! I do love brownies, and these are right up there at the top with my Peanut Butter Stuffed Brownies and Turtle Brownies!
Who doesn’t love homemade brownies? Although brownie mixes have come a long way, these rich and fudgy brownies are the best with easy brownie ingredients!
For best results be sure to buy the best quality ingredients you can afford, especially the chocolate and butter.
How to Make Mint Brownies from Scratch
- Preheat your oven to 350 degrees F and lightly grease a 9×9-inch baking pan or you could also line it with parchment paper. I like to use parchment paper so you can easily lift the brownies out for cutting.
- Melt the butter and chocolate chips together in the microwave or double boiler until smooth. Cool completely!
- In a bowl, mix together the eggs and granulated sugar until well combined then the vanilla extract. You could also add a little mint extract if you’d like.
- Once your chocolate and butter is cool, beat or mix it into the eggs and sugar. Make sure your chocolate and butter is cool. If it’s hot, it will cook the eggs and you’ll end up with scrambled eggs.
- Beat in the dry ingredients including the baking powder, salt, and flour. You can mix the dry ingredients together in a separate bowl, and probably should for best results, but I was in a hurry. haha!
- Pour the batter into the pan and bake about 30-35 minutes. Cool completely before frosting!
Instead of taking a bunch of step-by-step photos I took a video of everything (below) so you can see all the steps. Scroll down for the full printable recipe card as well.
Tips for Fudgy Brownies
- The small amount of flour in this recipe helps make them more chewy and gooey rather than cakey.
- Halfway through baking, if you’d like, you can remove the pan from the oven and tap it on the counter to help get rid of any air bubbles.
- Don’t make any ingredient substitutions. Making substitutions can result in a very different brownie.
How to Make Mint Chip Frosting:
When the brownies are completely cooled (yes I know I just said that, but it’s really important), make the frosting. You may want to add more or less mint extract depending on how much you like mint.
For the chopped chocolate, I bought chocolate chunks (near the “chips”), and chopped them on a cutting board with a sharp knife. You could also use chocolate chips or mini chips but I personally like the small chunks. You could also chop up some chocolate bars (leftover holiday candy perhaps?).
The frosting recipe makes a lot of frosting! Ok maybe not THAT much, but it does make a nice good thick layer of frosting on the brownies. If you just want a really thin layer of frosting, cut the recipe in half. I loved the frosting so can’t imagine using less, but that’s just me, ha!
These homemade Mint Chip Brownies are rich and decadent, so small squares are probably best. But who am I kidding, big pieces would be great too.
To easily cut the brownies, put the pan of brownies in the refrigerator for a few hours if you can wait that long. Cut into 36 small squares or as big as you’d like.
Can You Freeze Brownies?
YES! These brownies, like most brownies, freeze very well. There are a few different ways to do it…
- COVER PAN – The easiest is to just cover the pan and place in the freezer. Best to place a cover RIGHT on the frosting so there’s no air. This can get a bit messy though when you defrost them.
- COVER BROWNIES – You can remove the brownies from the pan and place on some plastic wrap (or silicone mat, parchment paper, or wax paper) on top of a large baking sheet. Place the pan in the freezer and once frozen, wrap tightly with plastic wrap and wrap in aluminum foil or place in a sealable bag or airtight container. If the brownies do not have frosting, you can wrap them right out of the pan and freeze.
- FREEZE SLICES – I like to cut the brownies into slices then place them on a silicone (or you could use wax paper, parchment paper, or plastic wrap) lined baking sheet. Freeze until frozen, then place in a bag and remove as much air as possible.
These Mint Brownies are the perfect green dessert for St. Patrick’s Day (March 17th) or National Brownie Day (December 8th) or just because you like chocolate and mint. haha!

Mint Brownies Recipe
