Mint Hair Salon: Fresh Mint Chocolate Chip Cookies

Mint hair salon is a playful name for mint chocolate chip cookies: crisp-edged, soft-centered cookies with cool mint flavor and pockets of chocolate. This straightforward batch uses peppermint extract, butter, brown sugar, and chocolate chips, so the dough needs no special equipment or chilling time.

Ingredients

2¼ cups (280 g) all-purpose flour, spooned into the measuring cup and leveled
1 teaspoon (5 g) baking soda
½ teaspoon (3 g) fine salt
¾ cup (170 g) unsalted butter, softened but not melted
¾ cup (150 g) packed light brown sugar
½ cup (100 g) granulated sugar
1 large egg, at room temperature
1 teaspoon (5 ml) vanilla extract
½ teaspoon (2.5 ml) peppermint extract, or up to ¾ teaspoon (3.75 ml) for a stronger mint flavor
1½ cups (255 g) semisweet chocolate chips
2 tablespoons (12 g) finely chopped fresh mint, optional
2 tablespoons (25 g) granulated sugar, optional, for lightly pressing onto the dough tops

Instructions

Heat the oven to 350°F (175°C). Line two baking sheets with parchment paper. If baking one sheet at a time, keep the second portion of dough at room temperature while the first batch bakes.
In a medium bowl, whisk together the flour, baking soda, and salt. Set aside. Measuring the flour by weight helps prevent dry, dense cookies; if using cups, fluff it first, spoon it into the cup, and level without packing.
In a large bowl, beat the softened butter with the brown sugar and ½ cup granulated sugar for about 2 minutes, until creamy and evenly combined. A hand mixer makes this easy, but a sturdy spoon and a little extra effort also work. Avoid beating until very airy, which can make the cookies spread unpredictably.
Beat in the egg, vanilla, and peppermint extract until smooth. Start with ½ teaspoon peppermint extract; brands vary in strength, and too much can make the cookies taste medicinal. Fold in the dry ingredients just until no flour streaks remain, then fold in the chocolate chips and optional chopped mint.
Scoop the dough into 24 portions, about 1½ tablespoons (30 g) each, and arrange them at least 2 inches (5 cm) apart on the prepared sheets. If desired, sprinkle the tops with a little of the remaining 2 tablespoons sugar. Do not flatten them heavily; the dough will spread as it bakes.
Bake one sheet at a time for 10–12 minutes, rotating the sheet once if your oven browns unevenly. The edges should look set and lightly golden while the centers still look soft. For food safety, the egg-containing cookies must reach the USDA FSIS safe minimum internal temperature of 160°F (71°C); check a center cookie with a food thermometer if there is any doubt. Do not rely only on browning, since cookies can look pale when done.
Leave the cookies on the baking sheet for 5 minutes to firm, then transfer them to a cooling rack. Bake the remaining dough in the same way. Allow the sheets to cool before reusing them, or the dough may spread too quickly.

Tips

Measure peppermint carefully. For a gentle mint note, use ½ teaspoon; increase gradually next time rather than pouring extra into the bowl. Peppermint extract is much more concentrated than fresh mint.
If you cannot find peppermint extract, use 1 teaspoon (5 ml) vanilla extract and the optional fresh mint for a milder, herbal flavor. Mint leaves alone will not produce the familiar candy-like taste of mint chocolate chip cookies.
For a dairy-free batch, use a firm baking stick labeled as a butter substitute, not a soft tub spread. The texture and spread can vary, so bake a test cookie and adjust the spacing if needed.
Do not overmix once the flour goes in. Mixing just until combined helps keep the centers tender; excessive mixing can develop gluten and make the cookies tough.

Serving Suggestions

Serve the cookies warm after their brief cooling period, when the chocolate is still soft, or let them cool completely for a neater snack. They pair well with cold milk, coffee, or hot cocoa. For a simple dessert, crumble one over a scoop of vanilla ice cream, or sandwich a small scoop of ice cream between two fully cooled cookies. If serving with ice cream, assemble just before eating so the cookies do not become soggy.

Variations

Use dark chocolate chips or chopped semisweet chocolate for a deeper cocoa flavor. White chocolate chips make the mint taste sweeter and creamier; use the same 1½ cups (255 g). For a green color, add a small amount of green food coloring with the egg, but it is optional and does not change the flavor. To make a more pronounced fresh-herb version, include the chopped mint, finely chopped so that larger leaf pieces do not interrupt the cookie texture. You can also replace up to ½ cup (85 g) of the chocolate chips with chopped toasted walnuts, though the result will be less chocolate-forward.

Storage and Reheating

Cool the cookies completely, then store them in an airtight container at room temperature for up to 4 days. Refrigeration is not necessary and can make them firm. For longer storage, freeze cooled cookies in a freezer-safe container with parchment between layers for up to 2 months; thaw at room temperature. Refrigerate any cookie dough containing raw egg if it will not be baked promptly, and bake it within 1–2 days. Do not leave perishable dough at room temperature for more than 2 hours. To warm baked cookies, heat them in a 300°F (150°C) oven for 3–5 minutes, or microwave one cookie for about 8–10 seconds; warmed cookies are for texture, not a substitute for safe cooking of raw dough.

Frequently Asked Questions

Can I make the dough ahead?
Yes. Cover and refrigerate it for up to 2 days. Let it sit at room temperature for about 15–20 minutes if it is too firm to scoop, then bake as directed. Chilled dough may spread less, so the cookies can be slightly thicker.

Why did my cookies spread too much?
The butter may have been melted or overly soft, the flour may have been under-measured, or the baking sheet may have been warm. Use softened butter that still holds its shape, measure flour carefully, and let sheets cool between batches.

Can I leave out the fresh mint?
Yes. Fresh mint is optional; the peppermint extract provides the main mint flavor. Without the leaves, the cookies have a smoother texture and a more classic mint-chocolate taste.

Can I use salted butter?
Yes. Use the same ¾ cup (170 g) and reduce the added fine salt to ¼ teaspoon (about 1.5 g). Salt levels vary among butter brands, so this adjustment keeps the cookies from tasting overly salty.

How do I know when the cookies are done?
The edges should be set and lightly golden, while the middle remains soft. They continue to firm on the hot sheet. Because the dough contains egg, the USDA FSIS safe minimum for egg dishes is 160°F (71°C); use a food thermometer in a center cookie when checking safety.

Can I freeze unbaked dough?
Yes. Scoop portions onto a tray, freeze until firm, then transfer them to a sealed freezer-safe bag for up to 2 months. Bake from frozen at 350°F (175°C), adding about 1–3 minutes and checking the centers for doneness.
