Ingredients You’ll Need
The magic of Mint Chocolate Cookie Bars starts with classic pantry staples and just a couple of special mix-ins. Each ingredient plays a starring role, from creating a perfectly soft crumb to delivering that signature chocolate-mint punch. Here’s what you’ll need—and why you’ll want every last bit:
- Unsalted Butter, softened: This is your golden ticket to a rich, tender base with a just-right chew.
- Granulated Sugar: Sweetens the batter and helps create those lightly crisped edges you’ll crave.
- Brown Sugar, packed: Adds depth of flavor and guarantees a perfectly moist, chewy texture in every bar.
- Large Eggs: They bring everything together, adding richness and helping the bars hold their shape.
- Vanilla Extract: Balances the peppermint and highlights the chocolate—don’t skip this classic!
- Peppermint Extract: The secret to that unmistakable cool, invigorating mint flavor.
- All-Purpose Flour: Forms the sturdy framework for your bars, giving them structure without making them cakey.
- Baking Soda: Lends a gentle lift for a soft, even crumb that doesn’t get dense.
- Salt: Rounds out the sweetness and sharpens both chocolate and mint flavors beautifully.
- Semisweet Chocolate Chips: For those classic cocoa pockets every great cookie bar has—don’t hold back!
- Mint Chocolate Chips or Chopped Andes Mints: These infuse each bite with cool mint and creamy chocolate—absolutely irresistible.
How to Make Mint Chocolate Cookie Bars
Step 1: Prepare the Pan
Start by preheating your oven to 350°F (175°C). Grab a 9×13-inch baking pan and give it a light greasing or, even easier, line it with parchment paper. This one simple step makes removing (and slicing) your Mint Chocolate Cookie Bars a breeze—they’ll pop right out with those beautiful clean edges every time.
Step 2: Cream Butter and Sugars
In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until the mixture is light, fluffy, and creamy. This usually takes about 2–3 minutes with an electric mixer and is crucial for that soft, classic cookie crumb.
Step 3: Add Eggs and Extracts
Next, beat in the eggs one at a time, followed by the vanilla extract and the magical peppermint extract. Mix until everything’s well incorporated—the peppermint scent wafting through your kitchen is the best preview of what’s to come!
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. This simple move ensures your leaveners and salt get perfectly distributed throughout the dough, which means even texture and flavor in every bar.
Step 5: Bring Dough Together
Slowly add the dry ingredients into your wet mixture, mixing just until combined. Be careful not to overmix—you want Mint Chocolate Cookie Bars with a delicate crumb, not tough ones!
Step 6: Fold in Chocolate and Mint
Now it’s time to stir in the semisweet chocolate chips alongside your mint chocolate chips or chopped Andes mints. Use a spatula or wooden spoon for this step so you don’t break up the chips and ensure they’re evenly distributed—you’ll want a bit of chocolate and mint in every bite.
Step 7: Spread and Bake
Spread the glorious dough evenly in your prepared pan. Smooth out the top (a silicone spatula works wonders here), and bake for 25–28 minutes. Look for golden edges and a center that’s just set—don’t overbake! Let the bars cool completely in the pan to set up for perfectly clean slices.
How to Serve Mint Chocolate Cookie Bars

Garnishes
Mint Chocolate Cookie Bars are delicious on their own, but a little garnish takes them over the top. Try a light drizzle of melted chocolate, a handful of chopped fresh mint, or a dusting of powdered sugar for extra flair. Feeling fancy? Add a scoop of vanilla ice cream on the side!
Side Dishes
Pair your bars with a glass of cold milk, a mug of hot cocoa, or a fresh-brewed coffee for the ultimate dessert experience. For a party platter, try serving alongside sliced strawberries or a fruit salad to balance the richness.
Creative Ways to Present
For special occasions, stack the Mint Chocolate Cookie Bars on a tiered platter or wrap individual bars in parchment and pretty twine for gifting. Cut the bars into triangles or bite-sized squares for a fun twist, or drizzle with colorful candy melts for holidays and parties.
Make Ahead and Storage
Storing Leftovers
These Mint Chocolate Cookie Bars stay fresh for up to 5 days when stored in an airtight container at room temperature. Layer parchment between the bars to prevent sticking and keep those perfect edges intact.
Freezing
Want to save some for later? Once cooled, wrap the bars individually or in layers separated by parchment paper, then freeze in a zip-top bag or airtight container for up to 2 months. They thaw surprisingly quickly—just 30 minutes at room temperature and they’re ready to enjoy!
Reheating
If you love your cookie bars warm and a bit gooey, give them a quick blast in the microwave for about 10–15 seconds. The chocolate gets all melty and the texture is just dreamy. For a more subtle warmth, you can reheat in a 300°F oven for 4–5 minutes.
FAQs
Can I use regular chocolate chips instead of mint chocolate chips?
Absolutely! If you can’t find mint chocolate chips or Andes mints, use regular semisweet or dark chocolate chips. Add a tiny bit more peppermint extract if you still want a pronounced mint flavor.
What’s the best way to cut Mint Chocolate Cookie Bars cleanly?
For neat, bakery-style squares, make sure the bars are completely cooled. Use a sharp knife, and wipe it clean between cuts for extra professional-looking slices.
Can I make these bars gluten-free?
Yes, you can substitute a quality 1-to-1 gluten-free flour blend for the all-purpose flour. The texture will be a tad different, but they’ll still taste fantastic!
How strong is the mint flavor?
The bars strike a nice balance between chocolate and mint, but if you’re a hardcore mint lover, you can bump up the peppermint extract just a touch. Be cautious, though—a little goes a long way!
Are Mint Chocolate Cookie Bars good for gifting?
They make wonderful homemade gifts! Once cooled and cut, wrap each bar in parchment and tuck them into a pretty box or tin—you’ll make any mint chocolate fan’s day.
