Can you imagine having these whenever the craving strikes?
What Ingredients are in Homemade Thin Mints?
Making these crisp, minty cookies at home requires just a handful of pantry staples that come together to create that iconic chocolate-mint flavor we all crave.
- 2 cups all-purpose flour
- ½ cup unsweetened cocoa powder
- ½ teaspoon salt
- 1 cup unsalted butter, softened
- ⅔ cup granulated sugar
- 1 large egg white
- 1 teaspoon vanilla extract
- ½ teaspoon peppermint extract
The quality of your cocoa powder and peppermint extract will make a big difference in the final flavor, so if you can, opt for a premium cocoa powder and pure (not imitation) peppermint extract for that authentic Thin Mint experience.
How to Make these Homemade Thin Mints
Step 1: Cream the Butter and Sugar
Take 1 cup of softened unsalted butter and ⅔ cup granulated sugar and beat them together until the mixture is smooth and fluffy.
This creates the perfect base for our cookies—can you already smell the minty goodness coming?
Using a stand mixer appliance will make the creaming process much more efficient and give you perfectly consistent results.
Step 2: Add the Wet Ingredients
Beat in 1 large egg white, 1 teaspoon vanilla extract, and ½ teaspoon peppermint extract until well combined.
The peppermint extract is what gives these cookies their distinctive minty character, so don’t skimp on quality here.
Step 3: Prepare the Dry Ingredients
In a separate bowl, whisk together 2 cups all-purpose flour, ½ cup unsweetened cocoa powder, and ½ teaspoon salt until thoroughly combined.
The cocoa powder adds that rich chocolatey flavor that pairs so perfectly with mint.
Step 4: Combine Wet and Dry Mixtures
Gradually add the dry ingredients to the butter mixture, stirring until everything is just incorporated.
The dough will be somewhat stiff, which is exactly what we want for these crisp cookies.
Step 5: Chill the Dough
Place the dough in the refrigerator for at least 30 minutes.
This essential step makes the dough much easier to handle when rolling and cutting—trust me, your future self will thank you for not skipping this part.
Step 6: Roll and Cut the Dough
On a lightly floured surface, roll the chilled dough to about ¼-inch thickness.
Using a round cookie cutter (or the rim of a glass, in a pinch), cut the dough into circles and place them on a parchment-lined baking sheet.
Step 7: Bake to Perfection
Bake the cookies at 350°F for 8-10 minutes, or until the edges are firm but not darkened.
They’ll continue to crisp up as they cool, giving you that classic Thin Mint snap.
Step 8: Cool and Store
Let the cookies cool completely on a wire rack before enjoying.
Store them in an airtight container to maintain freshness and that wonderful crisp texture we all crave from a proper Thin Mint.
What to Serve with Homemade Thin Mints
These crisp, minty chocolate cookies deserve some equally delightful companions. For the ultimate treat, serve them alongside a scoop of vanilla ice cream—the cool creaminess contrasts perfectly with the cookie’s snap.
Hot chocolate makes a natural pairing, especially when topped with a dollop of whipped cream. For coffee lovers, these cookies shine alongside an afternoon espresso or cappuccino.
If you’re feeling fancy, try them with a glass of Bailey’s or peppermint schnapps for grown-up gatherings. They also make a wonderful addition to dessert charcuterie boards with fresh berries and chocolate dips.
Perfect as an after-dinner treat or afternoon pick-me-up, these homemade Thin Mints are versatile enough to complement nearly any sweet occasion.
Homemade Thin Mints Substitutions and Variations
- Festive Touch: Sprinkle crushed candy canes on top before baking for holiday cookies, or drizzle with white chocolate for extra decadence.
- Add-Ins: Fold in mini chocolate chips or finely chopped nuts for texture contrast.
- Cocoa Variations: Dark cocoa powder creates an even richer flavor profile than regular unsweetened cocoa.
Leftovers and Storage for these Homemade Thin Mints
These homemade Thin Mints store beautifully, perhaps even better than their store-bought cousins!
Once completely cooled, place them in an airtight container with parchment paper between layers to prevent sticking. They’ll stay fresh at room temperature for up to 1 week.
For longer storage, these cookies freeze exceptionally well for up to 3 months.
Something magical happens in the freezer—the mint flavor intensifies and the texture becomes even more satisfying. Many cookie lovers actually prefer them straight from the freezer!
If your cookies begin to soften, a quick 5-minute stint in a 300°F oven will restore their crisp texture.
Just be sure to let them cool completely before storing again to prevent condensation and sogginess.
Final Thoughts
There’s something utterly nostalgic about the chocolate-mint combination in these homemade Thin Mints. The deep cocoa flavor paired with that cooling peppermint extract creates cookies that rival—dare I say surpass—the iconic boxed version we’ve all waited in line for.
They’re perfect for holiday cookie exchanges, when you’re craving something special between Girl Scout seasons, or simply when you want to impress friends with your baking prowess.
The simplicity of the ingredients belies how sophisticated these cookies taste, proving once again that sometimes the best treats come from our own kitchens rather than a package.
