Ingredients for Thin Mints Brownies

The ingredients for Thin Mints Brownies are a crucial element that brings this treat to life. Each component plays a role in creating the delectable taste and texture that makes these brownies so special. From the rich brownie mix to the subtle hint of mint, every ingredient complements the others to form a deliciously cohesive dessert.
- 1 (14.1-oz) box Pillsbury™ Thin Mints® Brownie Mix: This brownie mix serves as the foundation of the recipe, providing a rich chocolate flavor and fudgy texture.
- 3 tablespoons water: A simple yet essential ingredient that helps to activate the brownie mix and achieve the right consistency.
- 1/3 cup oil: Adding moisture and richness, the oil ensures the brownies stay soft and chewy.
- 1 egg: The egg binds all the ingredients together, contributing to the structure and making the brownies tender.
How to Assemble Thin Mints Brownies

Making Thin Mints Brownies is a straightforward process that anyone can master. I love how quickly you can go from gathering ingredients to enjoying a warm brownie. Here’s how to bring these delightful treats to life!
- Preheat your oven to 350 degrees Fahrenheit if you’re using a metal or glass pan. For a dark-coated pan, reduce the temperature to 325 degrees. This step is crucial because it ensures that your brownies bake evenly.
- Prepare your baking pan by coating the bottom with no-stick cooking spray. This will prevent the brownies from sticking and make it easier to cut them into perfect squares later on.
- In a large mixing bowl, combine the brownie mix, water, oil, and egg. Stir the mixture until it’s well blended—aim for about 50 strokes. This is where the magic begins; the aromas of the chocolate and mint will start to fill your kitchen.
- Spread the brownie batter evenly into the prepared pan. Use a spatula to ensure it’s nicely smoothed out, reaching the corners and edges for an even bake.
- Pop the pan into the preheated oven. For an 8×8-inch pan, bake for 29 to 32 minutes; if you’re using a 9×9-inch pan, aim for 26 to 29 minutes. Keep an eye on them—the smell alone can be tempting!
- Once baked, you’ll want to let the brownies cool completely in the pan before cutting them. This cooling time allows them to firm up, making them easier to cut into squares. It’s worth the wait!
- After they’ve cooled, cut them into squares and serve. You can dust them with powdered sugar for a touch of elegance or simply enjoy them as they are. Either way, you’re in for a treat!
- Store any leftovers loosely covered at room temperature. Although I doubt there will be many leftovers!
Things Worth Knowing
- Use a toothpick: Check for doneness by inserting a toothpick in the center of the brownies. If it comes out with a few moist crumbs, they are perfect!
- Cool completely: Allow brownies to cool completely in the pan to achieve the best texture for cutting and serving.
- Adjust baking time: Remember that different pans can affect baking time, so keep an eye on your brownies as they bake.
- Don’t overmix: When stirring the ingredients together, avoid overmixing. This will keep your brownies soft and fudgy.
Customization Ideas

If you’re looking to add a personal touch to your Thin Mints Brownies, there are plenty of ways to customize this delightful treat. Each option opens up a new flavor experience, allowing you to create something uniquely yours. Here are some ideas to get you started:

- Crushed Thin Mints: Sprinkle crushed Thin Mints on top before baking for added texture and a stronger mint flavor.
- Swirl in peanut butter: For a unique twist, swirl in some peanut butter into the brownie batter before baking.
- Serve with ice cream: Pair warm brownies with a scoop of vanilla or mint ice cream for a delightful dessert experience.
- Decorate with whipped cream: Add a dollop of whipped cream on top for a light and airy finish.
