What kind of brownie box mix works best?

A fudgy brownie mix works best for mint brownies. It gives you soft centers and chewy edges that pair perfectly with the cool mint flavor. Cakey mixes will work too, but the texture will be lighter.

How do I Store brownies?

Store them in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to 5 days. Chilling them can actually make the mint flavor even better.

Can I freeze Mint Brownies?

Yes! Store them in a freezer safe container for up to 3 months.

Green Food Coloring – It’s up to you how much you use. Start with a few drops and add more depending on how green you like it!
