These Peppermint Oreo Cookies turned out insanely good. I've been playing with this recipe in my kitchen over many seasons and finally nailed the perfect holiday treat. When crunchy Oreos meet smooth white chocolate and refreshing peppermint, each bite becomes something magical. My folks start asking for these the minute December rolls around, and they disappear quicker than any other sweet at holiday get-togethers.
Why These Cookies Stand Out
I'm totally in love with how these cookies turn out. They get this amazing crunchy edge but stay wonderfully soft in the middle. The tiny bits of peppermint and Oreo chunks make every mouthful interesting. They're a blast to bake with the kids and always the first gone at cookie swaps. And wow, they fill your home with the most wonderful smell while they're in the oven.
Your Ingredient List
- Butter: Pick cold, diced unsalted butter for the best cookie foundation.
- Granulated and Brown Sugar: Gives sweetness and makes them nicely chewy.
- Egg: Brings moisture and holds everything together.
- Vanilla Extract: Boosts the whole taste profile.
- All-Purpose Flour: The main building block for your dough.
- Baking Soda & Baking Powder: Makes the cookies puff up and keep their shape.
- Salt & Cornstarch: Evens out flavors and keeps them tender.
- Mix-Ins: White and semi-sweet chocolate chips, Oreo pieces, and peppermint candies for that festive touch.
Baking Steps Made Easy
- Get Your Oven Ready
- Warm up the oven to 350°F (175°C). Put parchment paper or silicone mats on your baking trays.
- Blend Wet Stuff
- Beat cold butter with sugars until light and airy. Drop in the egg and vanilla, mixing well.
- Add Dry Stuff
- Slowly mix in flour, baking soda, baking powder, cornstarch, and salt. Stop mixing when just combined.
- Add Your Tasty Bits
- Gently stir in Oreo chunks, chocolate chips, and peppermint candy pieces by hand so they spread out nicely.
- Form and Bake
- Scoop dough balls onto your trays. Top with extra goodies and bake for 9–11 minutes until the edges look set.
- Let Them Rest
- Keep cookies on the hot tray for 5 minutes before moving them to a cooling rack.
How To Store Them
You can keep these tasty treats for about a week if you store them in a sealed container on your counter. I like to make tons and chuck them in the freezer where they stay good for up to 3 months. Just put some parchment between layers so they don't get stuck together. Let them sit out when you want to eat them again.
Ways To Switch It Up
I sometimes use smashed candy canes instead of the peppermint candy. Dark chocolate chips give a richer flavor and the kids go crazy when I toss in some holiday sprinkles. A small handful of chopped pecans adds a nice crunch. If you're really into mint flavors, try adding a tiny splash of peppermint extract.
Insider Baking Tricks
After making so many batches, I've figured out some good tricks. A cookie scoop really helps them bake more evenly. If your house is warm, stick the dough in the fridge for a bit so they don't spread too much. I always put extra Oreo bits and chocolate chips on top before they go in the oven so they look super pretty.
What To Enjoy Them With
These cookies taste amazing dunked in cold milk but they're also great with hot chocolate. During Christmas season I love having them with peppermint mochas. They make wonderful gifts wrapped in holiday containers and my kids always want them with a scoop of vanilla ice cream for a special treat.
The Ultimate Holiday Cookie
These treats nail everything you want sweet minty chocolatey plus that awesome Oreo crunch. Whenever I take them to gatherings folks can't get enough. They're easy enough for everyday baking but fancy enough for your best holiday parties. Take my word for it once you try them they'll become part of your yearly traditions too.
