Thin Mints S’mores Cupcakes

Thin Mint S'mores Cupcakes

It’s the most wonderful time of the yeaaar…no, it’s not Christmas – it’s Girl Scouts cookie season! Like most people, I can’t resist a box of Thin Mints. And there’s only one thing better than a plain Thin Mint: a Thin Mints s’more. It’s one of those desserts that’s so simple to make yet SO delicious.

While keeping it simple is fun, I wanted to take Thin Mints s’mores to the next level. I put them together with my favorite chocolate cupcakes and s’mores cupcakes to come up with these epic Thin Mints S’mores Cupcakes.

They have a Thin Mints cookie crust (to mimic a s’mores crust) at the bottom of a mint chocolate cupcake, which is topped with homemade marshmallow fluff. Before you toast the marshmallow, top them off with a Thin Mint cut in half and made into a mini s’mores for the perfect topping. Thin Mints s’mores on top of Thin Mints s’mores! 😀

Thin Mints Cookie Crust
Step 1
Line 2 cupcake tins with 16 foil cupcake liners. Preheat oven to 350°F.
Step 2
In a small bowl, mix together crushed Thin Mints, melted butter and salt with a fork.

Step 5
In a small bowl, stir together cocoa powder and boiling water until smooth. Set aside to cool.
Step 6
In a medium bowl, stir together flour, baking powder, and salt. Set aside.
Step 7
In a large bowl, beat butter and sugar together until light and fluffy. Add eggs, one at a time, beating in between until incorporated. Stir in vanilla.
Step 8
Add flour mixture to butter mixture and beat until just combined. Add cooled cocoa mixture and mix until incorporated.
Step 9
Distribute cupcake batter evenly on top of prepared Thin Mint crusts (the liners will be almost full). Bake around 20-22 minutes, until tops spring back when lightly touched (or a toothpick inserted in the middle comes out clean). Let cool completely before frosting.

Step 10
In the meantime, prepare the frosting: Place egg whites in a large mixing bowl. Using an electric mixer with a whisk attachment, beat the egg whites until light and frothy. Keep the mixer running and slowly pour in 2 tablespoons of sugar. Continue to beat until soft peaks form.
Step 11
In a medium saucepan, combine 1/3 cup water, corn syrup, and remaining 2/3 cup sugar over medium heat. Bring to a boil and continue to cook, stirring occasionally, until it reaches 240°F (around 10-15 minutes). Turn mixer on to low and slowly pour syrup down the side of the bowl into the egg white mixture.
Step 12
Increase speed to high and beat mixture for 4 minutes, until thickened. Pour vanilla into mixture and beat on high for around another minute, until mixture looks like glossy, thick marshmallow fluff.
Assemble the Cupcakes
Step 13
When ready to serve, top cupcakes with a large dollop of marshmallow fluff frosting. Slice a Thin Mint in half, add some frosting in between the halves, and place on top. Use a small kitchen torch to lightly brown the frosting, then serve immediately.
