This Chocolate Thin Mint Brownies Recipe is a family classic. They are the perfect dessert to take to a party or potluck dinner because they make so many (and they are so rich that you can only handle a small brownie at a time).
I am a sucker for anything with mint and chocolate together and these didn’t disappoint.
The combination is truly a match made in heaven.
They really do taste like thin mints in brownie form, and are way more creamy and smooth.
If you are looking for a delicious and simple brownie recipe, this is one you need to try.
How To store Thin Mint Brownies:
These Chocolate Thin Mint Brownies can sit at room temperature for a few hours, but after that, we would recommend storing them in the refrigerator in an airtight container for 3-4 days.
If you are making them more than 4 days in advance, we highly recommend placing them in an airtight container (try to not stack them. You may need a few containers), and removing them from the freezer 24 hours before serving.

How to get a clean cut Thin Mint Brownie:
There are three things to know to get a perfectly clean-cut brownie.
- Cool your brownies completely before cutting (chilled in the refrigerator is even better!).
- Use a sharp knife. A lot of problems in the kitchen can be solved by using a really good knife.
- Run your knife under warm-hot water before cutting.
- Wipe your knife on a paper towel, or cutting board edge, after each cut if frosting has accumulated.
- You may need to re-heat your knife in the hot water throughout the cutting process, for best results.

How long can these brownies be made ahead of time? I have a cookie exchange on Christmas Eve but I would like to make them about a week ahead of time. 1. Can this be done without them tasting bad/old? 2. If yes, would you suggest I put them in an airtight container in the fridge, freezer or at room temperature? 3. And if yes, should I make the entire bar including the mint and chocolate frosting on top before I put them in the container or should I just make the brownies, freeze those and then on the day before make the mint and frosting topping? Thanks!

This is my favorite brownie recipe by far! What is the trick for keep the layers from coming apart? I've heard of using a toothpick to connect the layers before freezing.
