Easter feels very far away this year, being that it is at the end of April. Not only does Easter feel extraordinarily far away but it also feels like it’s been awhile since our last excuse to celebrate something.

I guess Valentine’s Day was only a few weeks ago but still these end of winter days seem to last weeks, don’t they? So we might as well use them for something enjoyable and productive like making the most amazing chocolate mint cupcakes to celebrate St. Patrick’s Day.

There are no shortcuts with this recipe. The whole thing is 100 percent from scratch. But it’s definitely worth it.

The chocolate cupcakes themselves are moist and tender thanks to the addition of buttermilk. I highly recommend not substituting plain milk for the buttermilk. Buttermilk itself is slightly acidic but not nearly as sour as other acids used in baking like lemon juice or vinegar. The slightly acidic batter promotes moist cupcakes because it breaks down the tough strands of gluten that make baked goods tough. Plus, buttermilk is thicker than regular milk, leading to a softer, richer consistency in the finished product.

Making the cupcake batter itself is not difficult. Just whisk together the dry ingredients in a large bowl and set aside. In a separate bowl, cream together the sugars, oil, buttermilk, vanilla, and egg. Then stir the dry ingredients into the wet ingredients a little at a time until combined. Be careful to mix until just combined without over mixing since over mixing can result in tougher baked goods. Then spoon the batter into a lined cupcake pan, filling each tin until they are 3/4 of the way full. After that, they go into the oven and bake for about 21 minutes. After that, let them cool fully. Then you can make your frosting.

This is where it gets really good. This frosting is the homemade frosting version of a Shamrock shake, but even better. If you are a mint fan, you will love this frosting. It’s lusciously creamy even with the crushed Oreos. And it’s sweet with a hint of chocolate from the Oreos but with the clean, refreshing flavor of mint.

It is a winner for sure. And all you need to do to make it is crush the Oreos in a food processor, then beat together the butter, heavy cream, Oreo crumbs, sugar, and mint flavoring and coloring until stiff peaks form. Not much more complicated than making a standard chocolate or vanilla frosting.

You could finish these cupcakes there, but I really wanted to dress them up and pack them with as much flavor as possible. So instead of just topping each with frosting, I chopped up some Andes Mints to sprinkle on top and garnished each cupcake with a halved Oreo. The result? A St Patrick’s Day Andes Mint Oreo Chocolate Cupcake that any leprechaun would love.
