Ingredients

2 eggs
1/2 cup granulated sugar
1/2 cup brown sugar
1/3 cup vegetable oil
2 teaspoons vanilla extract
3/4 cup flour
1/2 cup unsweetened cocoa powder
1/2 teaspoon baking soda
3/4 teaspoon baking powder
1/4 teaspoon salt
1/2 cup milk
2/3 cup chocolate chips (for ganache)
2-3 tablespoons heavy whipping cream (for ganache)
Vanilla frosting (store-bought or homemade)
Green food coloring
Thin Mints cookies (for topping)

Instructions

Step 1: Preheat your oven to 350°F and line a cupcake pan with silicone or paper liners.
Step 2: In a large bowl, whisk together the eggs, granulated sugar, brown sugar, vanilla extract, and vegetable oil until well combined.
Step 3: In a separate bowl, mix the flour, cocoa powder, baking soda, baking powder, and salt.
Step 4: Add half of the dry ingredients to the wet mixture and stir thoroughly.
Step 5: Pour in the milk and stir gently, then add the remaining dry ingredients. Mix carefully to avoid overmixing.
Step 6: Fill the cupcake liners halfway with batter and bake for 15-20 minutes. Check doneness by inserting a toothpick into the center; it should come out clean.
Step 7: Let the cupcakes cool completely on a wire rack before frosting.
Step 8: To make the ganache, combine chocolate chips and heavy cream in a small bowl. Microwave for 40 seconds, stir, and continue to microwave in short bursts until smooth.
Step 9: Dip the cooled cupcakes into the ganache, then place them right side up to set the coating.
Step 10: Tint your vanilla frosting with green food coloring to your preferred shade.
Step 11: Pipe the green frosting onto the ganache-topped cupcakes.
Step 12: Finish by placing a Thin Mints cookie on top of each cupcake. For extra texture, crush some Thin Mints and sprinkle over the frosting.

Tips & Variations

For a richer ganache, use higher quality dark chocolate chips or finely chopped bittersweet chocolate.
If you prefer, the ganache can be spread instead of dipping to create a thinner chocolate layer.
Substitute almond milk or oat milk for a dairy-free cupcake option.
Use mint extract in the frosting if you want a stronger mint flavor.
Try adding a tablespoon of coffee to the batter to deepen the chocolate flavor.

Storage

Store cupcakes in an airtight container at room temperature for up to 2 days. For longer storage, keep them refrigerated for up to 5 days. Allow refrigerated cupcakes to come to room temperature before serving or warm gently in the microwave. The ganache may firm up when cold but will soften as the cupcakes warm.

How to Serve

The image shows small chocolate cupcakes in white paper cups with green stripes. Each cupcake has three layers: a dark brown chocolate base, a smooth shiny layer of chocolate frosting, and a thick swirl of light green mint frosting on top. A round chocolate mint cookie is placed upright into the frosting on each cupcake. Around the cupcakes, there are more chocolate mint cookies lying flat on a white marbled surface, some stacked and some scattered. The scene has a soft focus background that highlights the front cupcakes. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I make these cupcakes vegan?

To make vegan Thin Mint cupcakes, you can replace the eggs with flax eggs or applesauce, use plant-based milk, and choose dairy-free chocolate chips and frosting. Note that texture and flavor will be slightly different.

How do I keep the ganache shiny and smooth?

Be careful not to overheat the ganache in the microwave—heat it in short bursts and stir well between heating. Using fresh heavy cream also helps maintain a glossy finish.
