There’s something magical about that first bite of a Peppermint Brownie Cookie – that moment when the fudgy, chocolate-rich center meets the crisp, candy cane-kissed exterior.

Whether you’re looking to impress guests or simply treat yourself to something special, these cookies deliver chocolate satisfaction with a cool, minty twist that’s absolutely irresistible.
Why This Recipe is Awesome
What makes Peppermint Brownie Cookies stand out in a sea of holiday treats?
It’s their perfect balance of textures – the crisp edges give way to that chewy, fudgy center that true brownie lovers crave. Unlike regular chocolate cookies, these have the intense depth of a proper brownie but in convenient cookie form.
The peppermint isn’t overwhelming – it’s a subtle companion to the rich chocolate, offering that refreshing coolness that makes these cookies feel festive yet sophisticated. They’re also incredibly versatile; make them as an everyday treat or dress them up with crushed candy canes on top for holiday gatherings.
Perhaps best of all, this recipe uses pantry staples with just one or two special ingredients, making it accessible even when a sudden cookie craving strikes.
The dramatic crackly top that forms while baking makes these cookies look professional without any fancy decorating skills required.
Equipment needed: Mixing bowls, electric mixer, baking sheets, parchment paper, cooling rack
Peppermint Brownie Cookies
Ingredients
- 1 cup 2 sticks unsalted butter
- 2 cups semi-sweet chocolate chips divided
- 1½ cups all-purpose flour
- ½ cup unsweetened cocoa powder
- 1 teaspoon baking powder
- ½ teaspoon salt
- 4 large eggs
- 1½ cups granulated sugar
- 2 teaspoons vanilla extract
- 1 teaspoon peppermint extract use ½ teaspoon for milder mint flavor
- ½ cup crushed candy canes or peppermint candies plus extra for garnish (optional)
Instructions
- Prepare your workspace and ingredients. Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper. This prevents sticking and makes cleanup easier.
- Melt the chocolate and butter base. In a microwave-safe bowl, combine 1 cup of chocolate chips and butter. Heat in 30-second intervals, stirring between each, until completely melted and smooth. Set aside to cool slightly.
- Mix the dry ingredients. In a separate bowl, whisk together flour, cocoa powder, baking powder, and salt until well combined and no cocoa lumps remain.
- Create the wet mixture. In a large bowl, beat eggs and sugar with an electric mixer on medium-high speed for 2-3 minutes until pale and fluffy – this creates that signature crackly top!
- Blend in the flavorings. Add vanilla extract, peppermint extract, and the melted chocolate mixture to the egg mixture. Beat on low speed until just combined.
- Incorporate the dry ingredients. Gradually add the flour mixture to the wet ingredients, mixing on low speed until just combined. Don’t overmix or your cookies will be tough.
- Fold in the add-ins. Gently fold in the remaining cup of chocolate chips and crushed peppermint candies (if using) with a spatula until evenly distributed.
- Shape the cookies. Drop rounded tablespoons of dough onto prepared baking sheets, spacing them about 2 inches apart as they will spread while baking.
- Bake to perfection. Bake for 10-12 minutes until the edges are set but the centers still appear slightly soft. The cookies will continue to set as they cool.
- Add the finishing touch. If desired, immediately sprinkle additional crushed candy canes on top while cookies are hot from the oven for a festive appearance.
- Allow proper cooling. Let cookies cool on baking sheets for 5 minutes before transferring to wire racks to cool completely.
Notes
- The cookie dough will be quite thick and fudgy – more like brownie batter than traditional cookie dough. This is exactly what you want!
- For best results, make sure your eggs are at room temperature before starting.
- These cookies freeze beautifully for up to 3 months. Layer them between parchment paper in an airtight container.
- The flavor actually improves after 24 hours as the mint and chocolate meld together.
- For a more striking appearance, use white chocolate chips instead of semi-sweet in the dough, creating a nice contrast.

Common Mistakes to Avoid
- Overheating the chocolate mixture – Always melt chocolate in short intervals and stir frequently to prevent burning, which creates a bitter taste.
- Skipping the cooling step – Adding hot melted chocolate to eggs can partially cook them, resulting in scrambled egg bits in your cookies!
- Using cold eggs – Cold eggs won’t incorporate as well, affecting the texture and that beautiful crackly top.
- Overmixing the dough – This activates too much gluten, making cookies tough instead of fudgy.
- Overbaking – These cookies should be slightly underbaked when removed from the oven. They’ll finish cooking on the hot baking sheet.
Alternatives & Substitutions
- Gluten-free option: Substitute all-purpose flour with a 1:1 gluten-free baking blend.
- Less sweet version: Reduce sugar to 1¼ cups and use dark chocolate chips instead of semi-sweet.
- Dairy-free adaptation: Use plant-based butter and dairy-free chocolate chips (note: texture may be slightly different).
- Mint alternatives: If you don’t have peppermint extract, use crushed peppermint candies in the dough, or try using mint chocolate chips instead of regular chocolate chips.
- Year-round version: Skip the candy canes and add ¼ teaspoon of espresso powder to enhance the chocolate flavor.
FAQs
Can I make the dough ahead of time?
Absolutely! The dough can be refrigerated for up to 3 days. Let it sit at room temperature for about 15 minutes before scooping and baking, as cold dough won’t spread properly.
Why did my cookies spread too much?
This typically happens if your butter was too warm or if the baking sheets were still hot from a previous batch. Try chilling the dough for 30 minutes before baking or using room-temperature baking sheets.
Can I leave out the peppermint for regular brownie cookies?
Definitely! Simply omit the peppermint extract and candy pieces for a delicious year-round chocolate brownie cookie. Consider adding a teaspoon of instant espresso powder to enhance the chocolate flavor.
How do I know when these cookies are done baking?
Look for set edges with slightly soft centers. They’ll appear a bit underdone but will continue to set while cooling. A toothpick inserted in the center should come out with a few moist crumbs, not completely clean.
How do I store these cookies?
Store in an airtight container at room temperature for up to 5 days. For longer storage, freeze for up to 3 months. The flavor actually improves after a day as the mint and chocolate flavors meld together!
