What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, and substitutions are easy if needed.

• For the Brownie Filling:
  • Unsweetened cocoa powder – ¼ cup (adds rich chocolate flavor)
  • Granulated sugar – ½ cup
  • All-purpose flour – ⅓ cup
  • Salt – ⅛ tsp
  • Unsalted butter – 3 tbsp, melted and cooled (I prefer Kerrygold for creaminess)
  • Large egg – 1 (room temperature)
  • Pure peppermint extract – ½ tsp
• For the Cookie Dough:
  • All-purpose flour – 1 ½ cups
  • Baking soda – ½ tsp
  • Salt – ½ tsp
  • Unsalted butter – ½ cup (1 stick), softened
  • Light brown sugar – ½ cup, packed
  • Granulated sugar – ¼ cup
  • Large egg – 1 (room temperature)
  • Vanilla extract – 1 tsp
  • Green food coloring – a few drops (optional, for that festive St. Patrick’s Day vibe)
• Extras:
  • Coarse sugar for topping (optional, adds crunch)

For a gluten-free version, swap the all-purpose flour with a 1:1 gluten-free baking flour. If dairy is a concern, almond or coconut oil can replace butter, but keep in mind it may slightly change the texture. I recommend using pure peppermint extract rather than mint flavoring for the freshest taste. In summer, you could swap peppermint with orange zest for a different twist, though mint is the star here.

Equipment Needed

• Mixing bowls (large and medium-sized)
• Electric hand mixer or stand mixer (a wooden spoon works too, just takes more elbow grease!)
• Measuring cups and spoons (accurate measurements make a big difference here)
• 8×8 inch baking pan (for the brownie layer)
• Baking sheet lined with parchment paper or a silicone mat
• Cooling rack
• Sharp knife and cutting board (to cut brownie squares)

If you don’t have an electric mixer, no worries—just mix the cookie dough a bit longer by hand. For the brownie pan, a metal one works best for even heat distribution, but glass is fine too. Keep your baking sheet cool between batches by chilling it briefly in the fridge to avoid spreading cookies.

Preparation Method

1. Make the Brownie Layer: Preheat your oven to 350°F (175°C). In a medium bowl, whisk together ¼ cup unsweetened cocoa powder, ½ cup granulated sugar, ⅓ cup flour, and ⅛ tsp salt. Stir in 3 tablespoons melted butter, 1 egg, and ½ teaspoon peppermint extract until smooth. Pour the batter evenly into a greased or parchment-lined 8×8 inch pan. Bake for 15-18 minutes until just set but still fudgy. Let cool completely on a wire rack (about 30 minutes).
   Tip: Don’t overbake the brownies—they should be soft to get that perfect gooey center.
2. Prepare the Cookie Dough: In a large bowl, whisk 1 ½ cups flour, ½ tsp baking soda, and ½ tsp salt. In a separate bowl, cream together ½ cup softened butter, ½ cup brown sugar, and ¼ cup granulated sugar until fluffy (about 3 minutes with a mixer). Beat in 1 egg, 1 tsp vanilla extract, and a few drops of green food coloring if using. Gradually add dry ingredients, mixing until just combined.
   Note: Overmixing the dough can make cookies tough, so stop as soon as the flour disappears.
3. Cut the Brownie into Squares: Once cooled, turn the brownie out onto a cutting board. Cut into 1-inch (2.5 cm) squares—aim for about 16 pieces.
   Pro tip: Use a sharp knife and wipe it clean between cuts for neat edges.
4. Assemble the Cookies: Preheat your oven to 350°F (175°C) again. Scoop about 2 tablespoons of cookie dough and flatten it into a disc in your palm. Place a brownie square in the center and wrap the dough around it, sealing completely so the brownie is enclosed. Roll gently into a ball. Place on a parchment-lined baking sheet, spacing 2 inches apart. Optionally, sprinkle with coarse sugar.
   Warning: Make sure the dough fully covers the brownie to prevent leaking during baking.
5. Bake and Cool: Bake for 12-14 minutes until cookie edges are golden but centers look slightly soft. Remove from oven and let cool on the sheet for 5 minutes before transferring to a wire rack. Cookies will firm up as they cool.
   Look for slight cracks on top—this usually means the brownies inside are perfectly fudgy.

Cooking Tips & Techniques

One thing I’ve learned is that temperature matters—a lot. Make sure your butter is softened but not melted for the cookie dough; this keeps the texture just right. When mixing, don’t overdo it, or your cookies might turn out cakey instead of chewy. Also, chilling the cookie dough for 15 minutes before assembling can help prevent spreading, but it’s not a dealbreaker if you’re short on time.

Wrapping the brownie squares can be a little fiddly at first, but a gentle touch and making sure the dough completely seals the brownie saves you from melted chocolate oozing in the oven. If your kitchen is warm, pop the assembled cookies into the fridge for 10 minutes before baking—they hold their shape better that way.

Honestly, I’ve had batches where the brownies were a bit overbaked, resulting in a drier center. To avoid that, keep a close eye on the brownies during their initial bake—they should look just set but still soft. When baking the stuffed cookies, don’t overbake; a few underdone minutes yield that chewy, gooey experience we all crave.

Variations & Adaptations

• Dietary Variation: Use almond flour and dairy-free butter substitute to make these cookies gluten-free and dairy-free. Add a flax egg (1 tbsp flaxseed meal + 3 tbsp water) to replace the egg if vegan.
• Seasonal Twist: Swap peppermint extract for orange zest and a splash of vanilla for a citrusy surprise. In summer, add freeze-dried raspberries inside the brownie squares for a fresh burst.
• Flavor Boost: Stir in chopped Andes mints or mint chocolate chips into the cookie dough for extra minty bites. A drizzle of melted dark chocolate after baking adds a classy finishing touch.

I once tried swapping the brownie center with a caramel-filled fudge square—talk about indulgence! It was a bit messy but totally worth it for a special occasion.

Serving & Storage Suggestions

These Mint Brownie Stuffed Cookies are best served warm or at room temperature with a glass of cold milk or a cup of hot tea. They make a stunning centerpiece for any St. Patrick’s Day dessert table, especially when plated alongside a few green sprinkles or shamrock candies.

Store them in an airtight container at room temperature for up to 3 days. For longer storage, freeze the cookies in a single layer on a baking sheet, then transfer to a freezer-safe bag for up to 2 months. Reheat gently in a 300°F (150°C) oven for 5-7 minutes to refresh their soft, gooey texture.

Flavors actually deepen overnight, so if you can resist, letting the cookies rest a day adds a lovely richness to both the cookie and brownie layers.

Nutritional Information & Benefits

Each cookie (makes about 16) contains approximately 220 calories, 10 grams of fat, 28 grams of carbs, and 3 grams of protein. The recipe uses real butter and eggs, providing a good source of energy and some essential nutrients.

Mint extract not only adds flavor but may help soothe digestion, which is a nice bonus after a big meal. Using high-quality cocoa powder brings antioxidants, and swapping ingredients like almond flour can boost fiber and reduce gluten content.

This treat is an occasional indulgence, but made from scratch with wholesome ingredients, it feels a little less guilty and a lot more special than store-bought sweets.
