This BYU chocolate mint brownies recipe delivers the signature fudgy-crunchy layers and bold peppermint flavor that make them legendary. The secret lies in using high-quality peppermint oil and a precise baking technique that creates those signature crackly tops while keeping the interior rich and moist.
I've perfected this recipe through years of testing, ensuring every bite delivers that perfect balance of chocolate intensity and refreshing mint. The key to achieving authentic BYU flavor is using a specific ratio of peppermint oil—just enough to enhance without overpowering the chocolate.
This recipe uses a combination of semi-sweet chocolate and unsweetened baking cocoa for depth, while a touch of corn syrup prevents cracking. The result is a brownie with a crackly crust that gives way to a fudgy interior, all infused with that signature minty aroma.
What sets these brownies apart is the texture contrast—the crispy edges and crackly top contrast beautifully with the soft, moist center. The peppermint flavor comes through in every bite, creating a dessert that's both indulgent and refreshing.

Ingredients for byu chocolate mint brownies
These legendary BYU brownies need just 11 ingredients for that signature fudgy-crunchy magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Semi-Sweet Chocolate Chips 🍫 | 12 oz | High-quality, not microwaveable |
| Unsweetened Baking Cocoa 🍫 | ½ cup | Dutch-processed for smoothness |
| Granulated Sugar 🍚 | 1 ½ cups | Superfine preferred for blending |
| Light Corn Syrup 🍯 | ¼ cup | Prevents cracking, don't skip |
| Unsalted Butter 🧈 | 1 cup | Room temperature, not melted |
| Large Eggs 🥚 | 2 whole | Room temperature for even mixing |
| Pure Peppermint Oil 🍃 | ½ tsp | High-quality, not extract |
| Vanilla Extract 🥛 | 1 tsp | Pure, not imitation |
| All-Purpose Flour 🌾 | ¾ cup | Sifted for light texture |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| White Distilled Vinegar 🍶 | 1 tbsp | Balances sweetness |
The chocolate is non-negotiable. Ghirardelli or Guittard chips melt beautifully, but avoid microwaveable brands—they're waxy and ruin texture. For the cocoa, Hershey's Special Dark or Dutch-processed is ideal. Peppermint oil makes or breaks this recipe: Frontier Co-op or Now Foods brands are top-tier. If your local store doesn't carry it, check the baking aisle at Whole Foods or order online. The corn syrup might seem odd, but it's what creates those signature crackly tops—don't substitute with honey or maple syrup.
No peppermint oil? Crushed candy canes or peppermint extract can work in a pinch, but the flavor won't be authentic. Running short on butter? Coconut oil at room temperature works, but texture will be slightly different. For the chocolate, chopped chocolate bars work if you're in a bind, but chips melt more evenly. The corn syrup is crucial—if you're avoiding it, try agave nectar at half the amount, though results may vary. And for the love of brownies, measure your flour properly—packing it changes the texture completely.
These brownies are best made a day ahead—the flavor develops and intensifies. Store in an airtight container at room temperature for 5-6 days, or freeze for up to 3 months for maximum freshness. For serving, I always recommend vanilla ice cream or whipped cream—the cold contrast makes them even better. Pro tip: Wrap individual portions in parchment before freezing for easy thawing.

Step-by-step instructions for BYU chocolate mint brownies
Here's the method that delivers that signature BYU fudgy-crunchy texture with perfect peppermint layers.
Melt Butter and Combine Wet Ingredients
In a medium saucepan over medium-low heat, melt the 1 cup unsalted butter until it just begins to foam. Remove from heat and whisk in the 1.5 cups granulated sugar, 0.25 cup light corn syrup, and 1 tbsp white distilled vinegar. The mixture should be smooth and fully combined—this is your flavor base.
Here's where the magic happens: stir in the 0.5 tsp pure peppermint oil and 1 tsp vanilla extract until fully incorporated. The peppermint oil is potent, so don't overdo it—this precise amount delivers that classic BYU mint flavor without overpowering. Let the mixture cool slightly but remain warm to the touch before moving to the next step.
Incorporate Chocolate and Cocoa
In a separate bowl, combine the 12 oz semi-sweet chocolate chips and 0.5 cup unsweetened baking cocoa. Pour the warm butter mixture over the chocolate and cocoa, then gently stir until completely melted and smooth. This step is crucial for preventing lumps—work quickly but thoroughly to create a glossy, homogeneous batter.
You'll know you're on the right track when the mixture reaches a thick, pudding-like consistency. If it looks too thin, let it sit for 2-3 minutes to thicken slightly. This texture ensures proper fudgy layers rather than cakey brownies. The Dutch-processed cocoa gives that signature rich chocolate flavor that pairs perfectly with the peppermint.
Add Eggs and Flour
Whisk in the 2 whole large eggs one at a time, mixing well after each addition until fully incorporated. The eggs help create that signature fudgy texture by binding the ingredients together. Next, sift in the 0.75 cup all-purpose flour and 0.5 tsp salt, mixing just until combined—overmixing develops gluten and can make the brownies tough.
This is where the vinegar comes into play—it reacts with the baking soda (if present) to create lift, but since we're not using any, it simply balances the sweetness and enhances the chocolate flavor. The batter should now be thick, glossy, and ready for the oven. If it looks too thick, you can gently fold in 1-2 tablespoons of hot water to loosen it slightly.
Bake to Perfect Fudgy Perfection
Preheat your oven to 350°F and line a 9x13-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal. Spread the batter evenly into the pan—this ensures consistent thickness and even baking. Tap the pan gently on the counter a few times to remove any air bubbles.
Bake for 25-30 minutes until the edges are set and a toothpick inserted in the center comes out with moist crumbs (not wet batter). The center should still look slightly underdone—this is key for that fudgy texture. The brownies will continue cooking as they cool. Don't overbake, or you'll end up with dry, cakey brownies instead of the rich, moist texture you're after.
Cool and Cut for Maximum Enjoyment
Remove the pan from the oven and let the brownies cool completely in the pan for at least 1 hour before cutting. This resting period allows the flavors to meld and the texture to set properly. The contrast between the fudgy interior and the slightly crispy edges is what makes these brownies so special.
Once cooled, use a sharp knife or pizza cutter to slice into 16 equal squares (about 2x2 inches each). For cleaner cuts, dip the knife in hot water between slices. Store in an airtight container in the refrigerator for up to 5 days, or freeze for up to 3 months. These brownies are even better the next day as the flavors deepen and the texture becomes more decadent.
Pro Tips For Making Byu Chocolate Mint Brownies
- Melt Butter Slowly: The BYU recipe calls for melted butter—don’t just toss it in the microwave and call it done. Heat it in 20-second bursts, stirring between each, until it’s just shimmering (not browned). I learned this the hard way after one batch tasted like burnt popcorn.
- Sift the Cocoa: Unsweetened baking cocoa is a powdery menace if you don’t sift it first. Packing it into your measuring cup means dense, dry brownies. Spoon it into the cup, level it off, then sift it directly into the bowl—this keeps the texture light and fudgy.
- Don’t Overmix the Batter: Once you fold in the chocolate chips and mint extract, mix just until combined. Overmixing adds air, which can make these dense. Use a spatula to gently fold—think "marble swirls," not "whipped meringue."
- Bake Until Slightly Under: The edges should look set, but the center should still wiggle like Jell-O when you jiggle the pan. Pull them out early if you’re impatient—they’ll keep cooking off the heat, and overbaking turns them into hockey pucks.
Health benefits of byu chocolate mint brownies
Rich Chocolate Benefits
These brownies deliver high-quality dark chocolate benefits through the 12 oz semi-sweet chocolate chips and ½ cup Dutch-processed cocoa. Dark chocolate contains flavonoids that support heart health by improving blood flow and lowering blood pressure. The Dutch-processed cocoa also provides magnesium, which aids muscle relaxation and sleep regulation. 💪
Mint's Digestive Perks
The ½ tsp pure peppermint oil isn't just for flavor—it offers genuine digestive benefits. Peppermint oil contains menthol, which helps relax intestinal muscles and may relieve symptoms of irritable bowel syndrome (IBS).
Just a small amount provides these benefits without overpowering the chocolate's richness. The oil also has mild antimicrobial properties that can freshen breath.
Energy-Boosting Ingredients
The combination of granulated sugar and corn syrup provides a quick energy source, while the eggs contribute high-quality protein for sustained energy. The butter adds healthy fats that support brain function and keep you feeling satisfied.
Together, these ingredients create a dessert that's indulgent yet balanced—perfect for a post-workout treat or celebration dessert.
Antioxidant Powerhouse
Both the dark chocolate and peppermint oil are packed with antioxidants that combat oxidative stress in your body. The flavonoids in chocolate help reduce inflammation, while rosmarinic acid in peppermint supports cellular health.
This makes these brownies not just delicious, but also a smart choice for satisfying sweet cravings with health benefits. ✨
Stress-Relief Indulgence
There's a reason these brownies are popular during stressful times—the combination of chocolate and mint creates a natural mood booster. Chocolate triggers the release of endorphins and serotonin, while peppermint's aroma has been shown to reduce stress hormones.
The rich, fudgy texture also provides comfort eating satisfaction that's harder to find in lighter desserts.
Portion Control Made Easy
With 16 perfect squares, these brownies make portion control simple. Each serving contains about 200-220 calories, making them a reasonable treat when enjoyed in moderation. The fudgy texture helps create satiety, so you're less likely to overindulge.
For a lighter option, try serving with Greek yogurt or whipped cream to add protein and reduce portion size.

Frequently asked questions
Why do these brownies have a crackly top?
The signature crackly top comes from the light corn syrup in the recipe. It creates a thin, crispy layer when baked, while keeping the interior rich and fudgy. This technique is what makes BYU brownies unique—don't skip it! The corn syrup also helps prevent over-browning while adding that satisfying texture contrast.
Can I substitute peppermint oil with peppermint extract?
You can try, but the flavor won't be authentic. Peppermint extract is much milder—you'd need about 1 tablespoon to match the intensity of ½ teaspoon peppermint oil. For best results, use pure peppermint oil (available at health food stores or online). If you're avoiding oil, crushed candy canes work in a pinch, but the flavor will be more subtle.
How do I prevent my brownies from being too cakey?
Overmixing develops gluten, which makes brownies cakey. Mix just until combined after adding flour, and avoid beating the batter vigorously. Also, don't overbake—remove them when the center still looks slightly underdone (25-30 minutes at 350°F). The corn syrup helps maintain fudginess, so don't substitute it with honey or maple syrup.
Can I make these brownies gluten-free?
Yes! Replace the ¾ cup all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill). For best results, add ½ teaspoon xanthan gum to help bind the texture. The flavor will remain rich, though the texture might be slightly denser than traditional brownies. Always check your gluten-free flour blend for baking-specific formulations.
Why do the brownies taste better the next day?
The flavors deepen as the peppermint oil and chocolate meld together over time. The crackly top also firms up slightly, creating a better texture contrast. For maximum flavor, let them cool completely in the pan for 1 hour before cutting, then store in an airtight container. The mint aroma actually intensifies as they sit!
