You’re about to discover how chocolate and mint create the perfect marriage in these classic brownies! While the combination might seem like a modern trend, these treats have been satisfying sweet cravings since the 1960s. Whether you’re craving a midnight snack or planning a party dessert, you’ll find these five-ingredient wonders surprisingly simple to make. Let’s explore how this retro favorite became a timeless indulgence and why it deserves a spot in your recipe collection.
History of Chocolate Mint Brownies
While chocolate and mint have been beloved flavor companions for centuries, the modern chocolate mint brownie emerged in the 1960s during America’s boxed dessert revolution.
You’ll find the roots of this classic treat in post-war convenience baking, when home cooks discovered they could elevate simple brownie mixes with creative additions.
The combination wasn’t entirely new – you’ve probably heard that the Ancient Egyptians chewed mint leaves after meals, while the Aztecs savored chocolate as a sacred drink.
But it wasn’t until companies started marketing mint-flavored baking chips that you could easily create these brownies at home.
Today’s version builds on this convenient innovation, and you’ll notice it’s become a staple at bake sales, holiday gatherings, and family celebrations across the country.
The perfect Recipe for Chocolate Mint Brownies
Chocolate Mint Brownies are a delightful fusion of rich chocolate and cool mint flavors, creating an indulgent dessert that satisfies both chocolate lovers and mint enthusiasts. The fudgy texture of the brownie base provides the perfect foundation for the invigorating mint chocolate chips scattered throughout.
This simplified five-ingredient version maintains all the classic taste while streamlining the preparation process. The result is a batch of perfectly balanced brownies that achieve the ideal combination of dense, chocolatey goodness and bright mint freshness, requiring minimal effort and basic pantry staples.
- 1 box brownie mix (18.3 oz)
- 2 large eggs
- 1/2 cup vegetable oil
- 1/4 cup water
- 1 cup mint chocolate chips
Preheat oven to 350°F (175°C) and line a 9×13-inch baking pan with parchment paper. Combine brownie mix, eggs, oil, and water in a large bowl, mixing until well blended. Fold in 3/4 cup of mint chocolate chips, then transfer batter to the prepared pan. Sprinkle remaining chips on top.
Bake for 25-30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. Cool completely before cutting into squares.
For best results, monitor the brownies carefully during the final minutes of baking, as overcooking can lead to dry, cakey brownies instead of the desired fudgy texture.
Store in an airtight container at room temperature for up to 5 days, or freeze for up to 3 months. To enhance the mint flavor, briefly microwave individual portions for 10-15 seconds before serving, which will slightly melt the chocolate chips and intensify their minty essence. Do not forget that these Chocolate Mint Brownies will always taste better when eaten warm.
Cooking Steps for the perfect Chocolate Mint Brownies
You’ll start by preheating your oven to 350°F, which guarantees your brownies will bake evenly from the start!
Next, you’ll combine the brownie mix, eggs, oil, and water in a large bowl until smooth, then fold in those delicious mint chocolate chips.
Finally, pour your minty mixture into a parchment-lined 9×13-inch pan and bake for 25-30 minutes, checking with a toothpick for that perfect fudgy texture.
step 1. Preheat Oven Temperature First

Starting with proper oven temperature is a critical first step for achieving perfectly fudgy chocolate mint brownies.
You’ll want to set your oven to 350°F (175°C) before you even think about mixing your ingredients – this guarantees you’re not left waiting for the oven to heat up while your batter sits.
While your oven’s preheating, take this time to gather your ingredients and line your 9×13-inch baking pan with parchment paper.
Don’t skip the parchment paper step – it’s your insurance policy against stuck brownies!
The preheating process typically takes 10-15 minutes, which is perfect for prep work.
You’ll know your oven’s ready when it beeps or when its indicator light shows it’s reached temperature.
Now you’re set to create those irresistible chocolate mint treats!
step 2. Combine Dry and Wet Ingredients

With your oven warming up nicely, it’s time to mix your ingredients together!
Grab your large mixing bowl and pour in the brownie mix – don’t worry about any lumps just yet.
Add your two eggs, 1/2 cup vegetable oil, and 1/4 cup water to the dry mixture.
You’ll want to stir everything until it’s well combined and smooth, making sure there aren’t any dry patches hiding at the bottom of the bowl.
Now comes the fun part – fold in 3/4 cup of those delicious mint chocolate chips! The remaining 1/4 cup will go on top later.
Your batter should look glossy and thick, similar to hot fudge sauce.
If you’re tempted to taste test (we’ve all been there!), remember that raw eggs aren’t your friend.
Pour this heavenly mixture into your parchment-lined pan.
step 3. Add Chips to Mixture

Sprinkle the remaining 1/4 cup of mint chocolate chips evenly across the top of your brownie batter – this creates that perfect spotted look we’re going for!
Before you sprinkle those final chips, you’ll want to fold 3/4 cup of the mint chocolate chips into your batter until they’re evenly distributed.
Don’t overmix here – you’re not training for an arm-wrestling competition! The chips should be visible throughout the mixture but not clumped together.
When you’re folding, use a gentle scooping motion from the bottom of the bowl upward. This technique guarantees every bite of your finished brownies will have that delightful mint chocolate surprise.
You’ll notice the batter becoming slightly thicker as you incorporate the chips, which is exactly what you want for that classic fudgy texture.
step 4. Pour Into Baking Pan

Now that your mint-studded batter is ready, grab your prepared 9×13-inch baking pan lined with parchment paper.
You’ll want to transfer the mixture with purpose – no dawdling, as the batter’s waiting to become brownies!
Pour the batter slowly into the pan, using a rubber spatula to guide it into all four corners.
Give the pan a gentle tap on the counter (two or three times should do it) to release any trapped air bubbles.
Next, use your spatula to smooth the top into an even layer.
Don’t forget to sprinkle those remaining mint chocolate chips across the surface – they’ll create delicious pools of minty chocolate as they bake.
Your batter should now be evenly distributed and ready for its transformation in the oven.
step 5. Bake Until Toothpick Test Passes

Place your pan of brownie batter into the preheated 350°F oven, positioning it on the center rack for even heating.
Set your timer for 25 minutes – that’s your minimum baking time to achieve that perfect fudgy texture.
Check for doneness by inserting a toothpick into the center of your brownies. You’re looking for a few moist crumbs on the toothpick, not completely clean or wet batter.
If needed, continue baking in 2-minute intervals until you achieve this result, but don’t exceed 30 minutes total.
The brownies might look slightly underdone, but don’t worry – they’ll continue to set as they cool. Trust the toothpick test! A clean toothpick means you’ve overbaked them, and nobody wants dry brownies with their mint chocolate chips.

These chocolate mint brownies deliver a perfect balance of fudgy chocolate and cool mint that’ll make them an instant favorite in your recipe collection.
