You’ll need the following ingredients to make these delicious Oreo peppermint brownies:
Brownie Mix: Any brownie mix will do! My fave is Ghiradelli, but I typically just buy whatever is on sale!
Instant Espresso Powder: Make sure you are using INSTANT ESPRESSO POWDER and not regular coffee grounds–yuck!
Mint Oreos: They usually sell mint Oreos year round. Any other peppermint or mint chocolate sandwich cookies will also work. I’ve used Trader Joe’s peppermint Joe Joes for this recipe, too.
HOW TO MAKE OREO PEPPERMINT BROWNIES: STEP BY STEP
Here are some quick visual instructions. Remember that full instructions with exact ingredients will be in the recipe card below!
Step 1: In a large bowl, mix brownie mix, oil, heavy cream, eggs, peppermint extract and espresso powder.
Step 2: Spread batter into a 9×9 (or 8×8) inch baking pan.

Step 4: Bake 30-40 minutes until a toothpick comes out clean. Sprinkle on candy cane pieces, if desired.
RECIPE TIPS & TRICKS
- To make brownies easy to remove from the pan, line the pan with parchment paper. Hold the parchment paper to the sides of the pan using two clips (I use bag clips, see photo above).
- Start checking brownies about 5 minutes before instructed on the package (usually about 30 minutes). Insert a toothpick into the center. If it’s clean or ALMOST clean, take the brownies out. They will continue to cook a bit when they come out of the oven.
- Storage: If there are any brownies left :), you can store them in an air tight container in the fridge for up to 4 days.
- Freezing: These brownies can be frozen in an airtight zip top freezer bag for up to 3 months.
ADDITIONS AND SUBSTITUTIONS
- Vegetable Oil: Any non flavored oil, like canola oil, also works.
- Heavy Cream: Buttermilk also works well in place of heavy cream.
- Brownies without Peppermint: Don’t like peppermint? Swap the peppermint extract with vanilla extract and use regular Oreos for the topping!
