Chocolate Mint Cupcakes

Looking for a quick chocolate fix? Look no further than these foolproof chocolate mint cupcakes! With an impossibly moist chocolate cupcake base topped with a sweet swirl of mint frosting, these cupcakes are sure to satisfy even the toughest craving.

About a month ago, while I was watching some news on the internet, I came across a segment about Georgetown Cupcake. I know I’m probably way behind the rest of you in discovering Georgetown Cupcake’s delightful little cupcakes but holy cow am I hooked!

To be more specific, I’m hooked on their signature swirl (I still live a little too far away to have actually tried their cupcakes at this point). There’s just something… perfect… about that low signature swirl… Maybe it’s how smooth the frosting is, or the fact that a little divot forms in the center, perfect for holding little bits of candy or sprinkles.

Either way, I just knew I had to learn how to make that swirl myself, and then use it to make these chocolate mint cupcakes with little pastel sprinkles!

How to make these chocolate mint cupcakes

First, make the chocolate cupcakes.

Start by preheating your oven to 350F and lining your cupcake pan(s) with cupcake liners.

In a large bowl, whisk together your chocolate with the hot water until the chocolate is completely melted. Alternatively, you can combine the chocolate with tap water and microwave it for about 30 seconds.

In the bowl of a stand mixer, whip your egg until frothy and lightened in color, then whip in the oil. Add the chocolate/water mixture and the milk, mixing on low until just combined.

Whisk in the rest of your cupcake ingredients, and pour your batter into your prepared cupcake pan(s). Bake for 18-20 minutes, or until a toothpick inserted into the cupcakes comes out clean.

Second, make the mint frosting.

While the cupcakes cool, you can whip up the frosting. In a large bowl, combine your butter and powdered sugar. Begin by beating the frosting on low, increasing to medium-high once the powdered sugar is incorporated.

Add your milk and mint extract, and beat until the frosting is light and fluffy (about 5 minutes). Mix in the green food coloring until the frosting is a light, mint green.

Finally, frost your chocolate mint cupcakes.

To frost these cupcakes with Georgetown Cupcakes signature swirl, spoon your frosting into a piping bag with a big, round tip (I used an Ateco 809).

Starting in the center, pipe out towards the edge and then back in, pushing the tip into the frosting before the releasing the pressure and pulling the tip back up. Georgetown Cupcakes and Pop Sugar have an awesome tutorial on this, which you can find here.

Garnish with sprinkles or coarsely chopped chocolate.

Tips for making these chocolate mint cupcakes

• Filling your cupcake liners: For a perfectly domed cupcake, fill you’re liners 2/3 of the way full. Any more and it’s likely to overflow.
• Knowing when your cupcakes are done: There are two ways to test for doneness. 1. Insert a tooth pick in the center of the cupcakes and if it comes out clean, it’s done. 2. Gently press the top of the cupcake and if it almost immediately springs back, it’s done.
• The secret to smooth, air-bubble free frosting: Once the frosting has come together, turn your stand mixer down to low and continue beating it for about 5 minutes. This should work out most of the air bubbles.
• Fill that piping bag like a pro: Spoon your frosting onto a large piece of plastic wrap, roll and twist the ends. Trim one end so there’s about ½” in length, drop your frosting into the piping bag (short end first) with the tip already on and pipe!
• Storing frosted cupcakes: While cupcakes are always best when eaten the same day they’re made, these can be stored in an air-tight container at room temperature for 1-2 days.
