Mint Chocolate Chip Cookies
Ingredients
Method
- Cream the butter and sugars. In a large bowl, beat the softened butter with the granulated sugar and brown sugar using a hand mixer or stand mixer for 2 to 3 minutes, until light and fluffy.
- Add the egg, yolk, mint, and color. Beat in the egg, then the egg yolk, then the peppermint extract. Add the green gel food coloring a drop at a time, mixing until you reach the shade of green you like.
- Add the dry ingredients. In a separate bowl, whisk together the flour, cornstarch, baking soda, and salt. Add to the wet mixture and stir just until combined, then fold in the chocolate chips.
- Scoop the dough. Preheat the oven to 350°F (175°C) and line baking sheets with parchment paper. Scoop 2-tablespoon balls of dough and place them 2 inches apart on the prepared sheets.
- Bake. Bake for 10 to 12 minutes, until the edges are set and the tops look just barely done. Cool on the pan for 5 minutes, then transfer to a wire rack.

Why Mint Chocolate Chip Cookies Works So Well
Peppermint extract is strong, so a little goes a long way. Just one teaspoon flavors the whole batch without tasting like toothpaste. The key is balance — enough mint to taste fresh and cool, but not so much that it overpowers the buttery cookie and chocolate. Pure peppermint extract (not mint extract, which is milder and different) gives the cleanest flavor.
Creaming the butter and sugar properly builds the texture. Beating softened butter with sugar for 2 to 3 minutes whips tiny air pockets into the mix. Those pockets expand in the oven and give the cookies lift, so they bake up thick instead of flat. Melted butter would make them spread thin — softened butter keeps them puffy.
Cornstarch is the secret softness trick. Just two teaspoons keep the cookies tender by interfering with gluten formation. It is the same trick bakeries use for melt-in-your-mouth texture. You will not taste it, but you will notice how soft every cookie stays, even on day three.
Key Ingredients Explained
- Unsalted butter: Three-quarters cup of butter, softened to room temperature. Softened butter creams properly and gives thick, puffy cookies.
- Granulated sugar: Half a cup of white sugar. It helps the edges crisp lightly.
- Brown sugar: Half a cup of packed light brown sugar. It keeps the centers soft and adds caramel notes.
- Egg: One large egg plus one yolk. The extra yolk adds richness and chew.
- Peppermint extract: One teaspoon of pure peppermint extract. This is the mint flavor — do not use imitation mint.
- Green food coloring: A few drops of green gel coloring. It gives the classic mint look. Use gel, not liquid, for bright color without thinning the dough.
- All-purpose flour: Two cups of flour. The structure of the cookie.
- Cornstarch: Two teaspoons of cornstarch. The secret to extra-soft cookies.
- Baking soda: One teaspoon of baking soda for lift.
- Chocolate chips: One cup of semi-sweet chocolate chips. They contrast perfectly with the cool mint.
Ingredients
- 3/4 cup unsalted butter, softened
- 1/2 cup granulated sugar
- 1/2 cup packed light brown sugar
- 1 large egg, room temperature
- 1 large egg yolk, room temperature
- 1 teaspoon pure peppermint extract
- 4 to 5 drops green gel food coloring
- 2 cups all-purpose flour
- 2 teaspoons cornstarch
- 1 teaspoon baking soda

How to Make Mint Chocolate Chip Cookies
Step 1: Cream the butter and sugars.
In a large bowl, beat the softened butter with both sugars using a hand mixer or stand mixer for 2 to 3 minutes, until light and fluffy.
Tip: Proper creaming takes a full 2 minutes — set a timer and do not rush it.
Step 2: Add egg, yolk, mint, and color.
Beat in the egg, then the yolk, then the peppermint extract. Add the green food coloring a drop at a time and mix until you reach the shade you like.
Tip: Gel coloring is strong — start with 3 drops and add more slowly.
Step 3: Add the dry ingredients.
In a separate bowl, whisk the flour, cornstarch, baking soda, and salt. Add to the wet mixture and stir just until combined. Fold in the chocolate chips.
Tip: Stop stirring as soon as no flour streaks remain.
Step 4: Scoop the dough.
Preheat the oven to 350°F (175°C). Line baking sheets with parchment. Scoop 2-tablespoon balls and place 2 inches apart.
Tip: No chilling needed — this dough holds its shape.
Step 5: Bake.
Bake for 10 to 12 minutes, until the edges are set and the tops look just barely done. The centers will look soft. Cool on the pan for 5 minutes, then move to a wire rack.
Tip: Pull them early — they firm up as they cool, and overbaking dries them out.
Recipe Tips
- Use pure peppermint extract. Imitation mint tastes artificial. Pure peppermint gives clean, fresh flavor.
- Do not overdo the mint. One teaspoon is perfect. More will taste like toothpaste.
- Room-temperature butter and eggs. Cold ingredients do not cream or mix properly.
- Underbake slightly. Soft centers are the goal. The cookies look underdone at 10 minutes — that is correct.
- Gel coloring over liquid. Liquid coloring waters down the dough. Gel gives bright color with just drops.
- Extra chips on top. Press a few chips into each dough ball for a pretty finish.
Variations
- Mint Oreo cookies: Swap the chocolate chips for 1 cup of crushed mint Oreo pieces.
- Double chocolate mint: Replace 1/4 cup of flour with cocoa powder for a chocolate-mint combo.
- White chocolate mint: Use white chocolate chips instead of semi-sweet for a sweeter cookie.
- Andes mint cookies: Press an Andes mint into the center of each warm cookie right after baking.
- No-color version: Skip the food coloring for the same great taste in a classic golden cookie.
What to Serve With
- Cold milk — the perfect cookie partner
- Hot chocolate — mint and chocolate love each other
- Vanilla ice cream — make the ultimate ice cream sandwich
- Coffee — the warmth balances the cool mint
- A holiday cookie platter — these bright green cookies stand out beautifully
Storage & Reheating
To store: Keep in an airtight container at room temperature for up to 5 days. The cornstarch keeps them soft the whole time.
To reheat: Microwave for 8 seconds to warm the chocolate. They taste freshly baked.
To freeze baked cookies: Layer with parchment in a freezer bag for up to 3 months. Thaw at room temperature.
To freeze dough: Scoop balls, freeze solid on a tray, then bag. Bake from frozen at 350°F for 12 to 14 minutes.
FAQs
Can I use mint extract instead of peppermint extract?
It works, but the flavor is different. Mint extract is a mix of spearmint and peppermint and tastes milder. Pure peppermint gives the classic cool flavor.
Why do my cookies taste like toothpaste?
Too much extract. Stick to 1 teaspoon. Peppermint is very strong, and extra ruins the balance.
Can I skip the food coloring?
Absolutely. The cookies taste exactly the same without it. The color is just for fun.
Can I make these without a mixer?
Yes. Soften the butter very well and beat by hand with a wooden spoon for 3 to 4 minutes. It takes more effort but works fine.
Why are my cookies flat?
The butter was too soft or melted. It should be soft enough to dent with a finger but still hold its shape. Also make sure your baking soda is fresh.
Can I use mini chocolate chips?
Yes. Use the same amount. Mini chips spread the chocolate more evenly through each cookie.
