Peppermint Brookies (Easy Christmas Cookie Brownies)

Peppermint Brookies (Chocolate Peppermint Cookie Brownies)

If you can’t decide between brownies and cookies, why not have both? These Peppermint Brookies combine a buttery sugar cookie crust with rich chocolate brownies, chocolate chips, peppermint extract, white chocolate drizzle, and festive peppermint M&M’s for the ultimate Christmas dessert.

Every year these are one of the first treats to disappear from my holiday dessert table. The combination of chewy sugar cookies and fudgy brownies creates two amazing desserts in one bite. The peppermint flavor is subtle enough that even people who aren’t huge mint fans usually come back for seconds.

One of my favorite shortcuts is using refrigerated sugar cookie dough when I’m short on time. It tastes fantastic and makes these holiday brookies even easier to prepare.

Whether you’re baking for a Christmas cookie exchange, holiday party, bake sale, or simply filling a dessert tray, these festive brookies are always a crowd favorite.

Ingredient Notes

Sugar Cookie Layer

This creates a soft, buttery base that makes these brownies extra special.

Peppermint Extract

Only a small amount is needed for a cool holiday flavor that doesn’t overpower the chocolate.

Peppermint M&M’s

These add festive color, crunch, and extra chocolate in every bite.

White Chocolate

A drizzle of white chocolate makes these brownies look bakery-worthy.

How to Make Peppermint Brookies

Step 1: Prepare the Pan

Preheat the oven to 350°F.

Line a 9×13-inch baking pan with aluminum foil.

Spray generously with nonstick cooking spray.

Step 2: Make the Cookie Layer

Prepare the sugar cookie dough according to the package directions.

Press the dough evenly into the prepared baking pan.

Step 3: Make the Brownie Batter

Prepare the brownie mix according to the package.

Mix in the peppermint extract.

Fold in the semi-sweet chocolate chips.

Pour the brownie batter over the cookie dough.

Spread evenly.

Step 4: Bake

Bake for 35–40 minutes until a toothpick inserted near the center comes out with only a few moist crumbs.

Allow the brownies to cool for about 1 hour.

Step 5: Slice

Lift the brownies from the pan using the foil.

Slice completely before decorating.

This prevents the white chocolate from cracking later.

Step 6: Decorate

Melt the white chocolate in a microwave-safe bag or bowl using 30-second intervals.

Drizzle over the brownies.

Immediately sprinkle with:

  • Peppermint M&M’s
  • Holiday sprinkles

Allow the chocolate to harden before serving.

Tips for Perfect Brookies

  • Slice before drizzling the white chocolate.
  • Refrigerated sugar cookie dough works perfectly.
  • Line the pan with foil for easy removal.
  • Don’t overbake the brownies.
  • Decorate while the white chocolate is still warm.

Variations

Triple Chocolate Brookies

Add white chocolate chips to the brownie batter.

Candy Cane Brookies

Replace the M&M’s with crushed candy canes.

Oreo Brookies

Add crushed Oreo cookies between the layers.

Hot Cocoa Brookies

Top with mini marshmallows after baking.

Valentine’s Brookies

Swap peppermint M&M’s for pink and red M&M’s.

Storage

Store in an airtight container for up to 5 days.

Refrigerate for up to 1 week.

Freeze individual bars for up to 3 months.
