Grinch Brownies are anything but “grinchy.” They’re a mix of rich chocolate and mint that are guaranteed to make any Grinch’s heart grow at least three sizes.

I never cease to be amazed at all the scrumptious things you can make with a box of brownie mix. Buy more than one box and you can also make our cute reindeer brownies and these decadent triple chocolate raspberry brownies.

Grinch Brownies

Let me first say that the person who invented Mint Oreo Cookies is a genius. Mint and chocolate were absolutely made to go together! Right?

If you’re as mad for mint and chocolate as I am, you’re going to flip for these.

They’re incredibly rich and delicious. You can thank the heavy cream and two kinds of chocolate for that.

Chopping the Oreos

You may be tempted to crush the Oreos in a baggie with a rolling pin, but if you can resist the urge, you should definitely try chopping them into quarters.

The chunks add a little something extra that I’d hate for you to miss.

Here’s a tip for you: freeze the Oreos before you chop them. It’ll make the job so much easier.

Let them come to room temperature after and it won’t change your recipe a bit.

Why You Should Use Parchment Paper

If you don’t have parchment paper, please get some! Once you use it to bake with, you’ll never want to be without it.

Not only does it make clean up incredibly easy, but it also helps your food cook more evenly.

Your brownies (or cookies, or anything else you bake) won’t spread the way it will in an unlined pan. That means fluffier goodies!

The Ganache

Ganache is a fancy word for chocolate and cream whipped together. (I’m sure you already knew that!)

The ganache in this recipe is a heavenly blend of white chocolate, heavy cream, and peppermint extract.

You might be tempted to sit down with a spoon and eat it all by itself, but don’t do it! The brownies come alive when you pour it on top. (Be sure the brownies are completely cooled first.)

    1. Hi Karebear. You con store these in an airtight container at room temperature for a few days or refrigerate for up to a week.

    Not overpowering in minty taste and I don’t like red hots either but these are great! Everyone said they tasted like a grass hopper cookie or ice cream.

  2. 5 stars
    Made this and added m&ms on top. 
    My ganache came out very liquidy. I did use a mixer to thicken. Didn’t thicken much. Overall love the flavor!

  3. 5 stars
    This is amazing! The ganache seemed too thin so I beat it with electric mixer about 5 minutes. This helped thicken up the heavy cream wonderfully. Will definitely make this a regular addition to my holiday entertaining.

    Super cute but my ganache is waaaay thinner than the photos here. Wish I would have doubled it or just used green buttercream.

    Does the parchment paper replace greasing the pan?  I’ve never used parchment paper before
