Ingredients for Thin Mint Cupcakes

For the Chocolate Cupcakes

• Large Eggs: It’s crucial to use room temperature eggs for a smooth, evenly baked batter. This helps them incorporate better with other ingredients.
• Unsweetened Cocoa Powder: For the best chocolate flavor, we recommend using a high-quality unsweetened cocoa powder, such as Hershey’s. Avoid Dutch-processed cocoa unless specified, as it reacts differently with leavening agents.
• Baking Soda: This acts as a leavening agent, creating a light and fluffy texture. If you’re out, check out our guide on Best Baking Soda Substitutes.
• Milk: Whole milk is ideal for achieving a rich, tender crumb in your cupcakes. Alternatively, you can use ½ cup of buttermilk for a slightly tangier flavor and even more moisture.
• All-Purpose Flour: Proper measurement is key! Spoon the flour into your measuring cup and then level it off with a knife. This method is more accurate than scooping directly from the bag, which can compact the flour and lead to dry cupcakes.
• Brown Sugar: We prefer light brown sugar for its subtle caramel notes and moisture, but dark brown sugar can also be used if you enjoy a deeper, richer molasses flavor.
• Granulated Sugar: Provides sweetness and contributes to the overall structure of the cupcakes.
• Vegetable Oil: Adds moisture and creates a tender crumb.
• Vanilla Extract: Pure vanilla extract enhances the overall flavor profile of the chocolate cake.
• Baking Powder: Another essential leavening agent that works with baking soda to give the cupcakes their rise.
• Salt: Balances the sweetness and amplifies the chocolate flavor.

For the Chocolate Ganache

• Chocolate Chips: The quality of your chocolate will significantly impact the flavor of your ganache. Opt for a good quality semi-sweet or dark chocolate chip for the best results.
• Heavy Whipping Cream: This is the secret to a rich, silky-smooth ganache. We highly recommend against substituting heavy cream, as it provides the necessary fat content and consistency.

For the Refreshing Mint Icing

• Butter: For the most delicious and creamy frosting, real unsalted butter at room temperature is essential.
• Vanilla Extract: A touch of pure vanilla extract rounds out the mint flavor beautifully.
• Mint or Peppermint Extract: You can choose either mint or peppermint extract based on your preference. Add it gradually, as the intensity can vary significantly between brands.
• Green Food Coloring: Gel food coloring is recommended for achieving a vibrant, festive green hue without altering the frosting’s consistency.
• Powdered Sugar: The base of any good buttercream, ensuring a smooth and sweet frosting.

Step-by-Step Guide to Making Thin Mint Cupcakes

Step 1: Prepare the Wet Ingredients. Begin by preheating your oven to 350°F (175°C) and lining a muffin pan with cupcake liners. In a large mixing bowl, combine the granulated sugar, eggs, brown sugar, vanilla extract, and vegetable oil. Whisk these ingredients together until they are thoroughly combined and the mixture appears light and creamy.

Step 2: Scrape and Re-Whisk. After the initial mixing, take a spatula and scrape down the sides of the bowl. This ensures all ingredients are fully incorporated. Give the mixture another quick whisk to ensure a smooth, uniform consistency.

Step 3: Combine Dry Ingredients. In a separate large mixing bowl, whisk together all the dry ingredients: all-purpose flour, unsweetened cocoa powder, baking soda, baking powder, and salt. Make sure they are well blended to ensure even distribution in the batter.

Step 4: Incorporate Wet and Dry. Gradually add about half of the dry ingredient mixture into the wet ingredients, stirring gently until just combined. Then, pour in the milk and stir again until incorporated. Finally, add the remaining dry ingredients. Mix until the batter is just smooth; be careful not to overmix, as this can lead to dense cupcakes.

Step 5: Fill the Muffin Tins. Using a cookie scoop or a spoon, fill each cupcake liner about halfway full. Filling them evenly ensures consistent baking. A cookie scoop can make this process quicker and less messy.

Step 6: Bake and Cool. Bake the cupcakes in the preheated oven for 15-20 minutes, or until a toothpick inserted into the center comes out clean. Once baked, remove them from the oven and let them cool in the muffin pan for a few minutes before transferring them to a wire cooling rack to cool completely. They must be fully cooled before frosting.

Step 7: Prepare the Chocolate Ganache. While the cupcakes are baking and cooling, you can start on the luscious chocolate ganache. Place the chocolate chips and heavy whipping cream into a small, microwave-safe bowl.

Step 8: Melt and Stir Ganache. Microwave the chocolate mixture in 40-second intervals. After each interval, remove the bowl and stir thoroughly. Continue this process until the ganache is completely smooth and glossy. Be patient, as gentle heating prevents scorching the chocolate.

How to Make Luscious Mint Frosting

1. Beat the Butter: In a stand mixer fitted with the paddle attachment, or using a hand mixer, beat the softened butter on medium speed until it is light, fluffy, and smooth. This typically takes 2-3 minutes.
2. Add Extracts: Incorporate the vanilla extract and mint or peppermint extract. Beat again until well combined. Remember to add the mint extract gradually, tasting as you go, to achieve your desired mint intensity, as strengths vary by brand.
3. Gradually Add Powdered Sugar: Slowly add the powdered sugar, one cup at a time, beating on low speed until fully incorporated. Once all the sugar is in, increase the speed and beat until the frosting is light and fluffy. If the frosting seems too thick, you can add milk (a tablespoon at a time) until you reach your desired smooth consistency for this delightful Mint Buttercream Frosting.

Decorating Your Thin Mint Cupcakes

Step 1: Dip in Ganache. Once your cupcakes are completely cool and the ganache has cooled slightly but is still pourable, gently dip the top of each cupcake into the chocolate ganache. Ensure a generous coating.

Step 2: Allow Ganache to Set. Quickly turn the cupcakes right side up and place them on a clean surface or wire rack. Allow the chocolate ganache to set slightly before proceeding with the frosting. This creates a beautiful, firm chocolate layer under your mint frosting.

3. Frost the Cupcakes: Transfer your prepared mint frosting into a piping bag fitted with your favorite tip (a star tip works wonderfully for a classic look). Alternatively, if you don’t have a piping bag, you can use a sturdy Ziploc bag with a corner snipped off. Pipe a generous swirl of mint frosting onto each ganache-dipped cupcake.
4. Garnish and Serve: For the ultimate presentation and flavor boost, garnish each cupcake. This step is optional but highly recommended! Place a whole Thin Mint cookie on top of the frosting. For extra indulgence, you can even crush a few extra cookies and sprinkle the crumbs over the top of the frosted cupcakes. Serve immediately and enjoy!

Expert Baking Tips for Perfect Cupcakes

• Room Temperature Ingredients: This is a golden rule for baking! Whether it’s butter, eggs, or milk for the batter or frosting, ensuring all ingredients are at room temperature allows them to emulsify better, creating a smoother, more uniform batter and a lighter, airier texture in your finished cupcakes and frosting.
• Measure Flour Accurately: Over-measured flour is a common culprit for dry, dense baked goods. Instead of scooping flour directly with your measuring cup, spoon the flour into the measuring cup and then level it off with a straight edge. This prevents compacting and ensures you use the correct amount.
• Check Your Leavening Agents: Baking powder and baking soda can lose their potency over time. Always check their expiration dates before baking. For baking powder, test by mixing a teaspoon with a little hot water; it should fizz immediately. For baking soda, add a quarter teaspoon to a small amount of vinegar; it should also fizz vigorously. If they don’t react, it’s time for fresh ones!
• Avoid Overmixing: Once you add the dry ingredients to the wet, mix only until just combined. Overmixing develops the gluten in the flour too much, resulting in tough, chewy, and dense cupcakes rather than light and tender ones. A few small lumps are perfectly fine.
• Frosting Variations: While our mint buttercream is divine, feel free to experiment! For another equally delicious option, you could consider using a rich Homemade Cream Cheese Frosting, adding a subtle tang that complements the chocolate beautifully.
• Quality Chocolate Matters: For both the cupcake base and especially the ganache, using good quality chocolate chips will make a noticeable difference in the overall flavor and richness of your Thin Mint Cupcakes.
• Cool Completely: Always ensure your cupcakes are entirely cool before adding ganache or frosting. If they are even slightly warm, the ganache will melt, and the frosting will slide right off.
