These thin mint cupcakes pair perfect chocolate cupcakes with an easy mint buttercream frosting. Top each Girl Scout Cupcake with a cookie for the best chocolate mint dessert.
I’m not going to lie it took me a long time embrace mint anything. I just couldn’t understand why mint was ruining my chocolate.
But as I grew up so did my palette. Now mint and chocolate is a welcome pairing here.
So when it’s what I call “Girl Scout” season I always snag a bag of Thin mint cookies. I thought this year why not turn that into a Thin Mint cupcake. Basically chocolate cupcakes with mint frosting. Super easy. Super delicious. And boy oh boy am I glad I did.
How To Make These Girl Scout Cupcakes – Step By Step
These easy chocolate cupcakes are my variation from the perfectly chocolate cake from Hershey’s Kitchens. You could stick to the original recipe, but I love my little twist on them- adding espresso powder. Adding espresso, or strongly brewed coffee to anything chocolate brings out the flavor of the chocolate.
First things first. Prepare your pans and pre-heat that oven. My Favorite Go To Cupcake Liners Are These.
This is a one bowl cupcake recipe that couldn’t get easier. Yes one bowl. I told you this is the only recipe you will ever need.
In a large bowl you need to combine the dry ingredients (flour, sugar, baking powder, cocoa powder, baking soda, and salt) and simply whisk to combine.
In the same bowl you then add your wet ingredients- milk, vegetable oil, vanilla, and eggs. And whisk, whisk, whisk again.
Then you need to add in your boiling water. The batter will be thin.
To fill your cupcake pans, I find it easiest to pour the batter into a liquid measuring cup and pour then into my cupcake pans.
You want to fill these up about 3/4 of the way to leave a bit of room for them to rise and create that beautiful domed cupcake.
Tips For Making These Thin Mint Cupcakes
- Measure Correctly – Be sure to measure your flour accurately. It’s easy to overmeasure your flour resulting in a dense cupcake. I always give my flour a stir first. Then spoon into my dry measuring cup and then level off. For a full tutorial on how to measure your flour click here.
- Use Natural Cocoa Powder– Be sure to use natural unsweetened cocoa powder not dutch process. They are not the same. You can read about the differences here between natural and dutch process cocoa powder.
- Rotate Your Pans – When baking these, it’s best to rotate the pans halfway through their baking time. Every oven can have hot spots so they may not bake evenly. Give them a turn in the oven, so they all bake up pretty. This is just one of 15 tips for baking perfect cupcakes every time.
- Cool Completely. Once they are baked, be sure to take them out of the pans and cool on a cooling rack. Leaving them in your pans means they will continue to bake and could end up dry.

Thin Mint Cupcakes
For the cupcakes
For the frosting (this is a single batch - I always make 3 batches to frost all the cupcakes)
- Heat oven to 350°F. Prepare two muffin pans with cupcake liners.
- Stir together sugar, flour, cocoa, baking powder, baking soda and salt in large bowl. Add eggs, milk, oil, vanilla extract beat on medium speed of mixer 2 minutes. In a measuring cup microwave 1 cup of water (or heat on stovetop). Stir in instant espresso. Add boiling water to batter. Stir to combine. (batter will be thin) to the cake batter. Fill each cupcake well about 3/4 cup full of batter.
- Bake for 22-25 minutes or until wooden pick inserted in center comes out clean, rotating pans halfway through baking. Remove cupcakes from pans and allow to cool on a wire rack. Cool completely. Repeat with the additional cupcake batter (about 6 additional cupcakes)
- For the frosting (note this is for a single batch, I always make 3 batches to frost all these cupcakes. If you like high swirls like I do then you will want to make a triple batch as well) combine the butter and powdered sugar and mix on low, then increase the speed for 2-3 minutes until light and fluffy. Add in your vanilla extract, peppermint extract, and heavy cream. Beat on medium-high for 8 minutes.
- With a pastry bag and tip attached, pipe the frosting on each cupcake. Decorate with a cookie. I also crushed up a few cookies and decorated with the cookie crumbs. Store at room temperature for up to 2 days. Refrigerate for up to 3 days, just bring back to room temperature before serving.
