These rich chocolate cupcakes are easy and delicious, and a bit of black gel color and some M&Ms are all you need to decorate! Grab your piping bags and M&Ms and make these fun Christmas light cupcakes!
Preheat oven to 350 degrees F (180C) or 325 FC (160C) for a convection oven. Line 24 muffin tins with cupcake liners. In the bowl of a stand mixer fitted with the paddle attachment, combine the flour, sugar, cocoa powder, baking soda, and salt. Add in bits of softened butter until it’s no longer visible in the dry ingredients and the mixture looks crumbly.
Whisk together eggs, buttermilk, and vanilla. Add to dry ingredients and mix until no dry ingredients are visible. Scrape down the bowl and beat for another 20 seconds.
Fill each paper 3/4 full (a large cookie scoop makes this a quick and easy process). You may find that you have some batter left over - I don't recommend over-filling the cupcake tins as they may overflow. Bake for 20-25 min or until a toothpick inserted comes out clean. Allow them to cool completely on a wire cooling rack before frosting.
The hang time while your cupcakes are cooling is a great time to make your filling and frosting!
Filling
Meanwhile, make your ganache. Place chocolate chips in a microwave-safe bowl. Add whipping cream and microwave on half power in 30-second intervals, stirring in between until smooth. Cool until pipeable; it's easier to fill the cupcakes if it's still soft and not chilled.
Once the cupcakes have cooled, you're ready to core them. There are a few ways you can do this....you can buy a cupcake corer, you can use the non-business-end of a large piping tip, or....you can do what I do and cut a cone-shaped core out with a plastic knife. Up to you. I haven't the foggiest idea why cupcake crumbs don't stick to plastic knives like they do regular knives, but the plastic knife's been working too well for me to feel the need to invest in any fancy corers.
Pipe your ganache into your cored cupcakes – this can be done with a a squeeze bottle or piping bag. A spoon will work if you don’t have any of the above, I've just found spoons to be a little bit more difficult to work with.
Frosting
Beat together softened cream cheese and butter; slowly add in powdered sugar alternating with milk until frosting reaches desired consistency. I recommend making it thick enough to hold its shape. Add vanilla and salt if needed and beat until well combined.
Remove about 1/3 cup frosting and stir in black gel color to make the Christmas light ‘wire.’
Decorating
Transfer your frosting to a large piping bag fitted with a large tip – I used a tip from my Amazon set similar to the Ateco #828. Pipe white frosting in large swirls onto your cupcakes. Transfer your black frosting to a standard size bag- I used a small round tip similar to the Wilton #2 tip. Add a swirl of black frosting to each cupcake, swirling up toward the top of the white frosting swirl.
Now you’re ready to add your M&Ms! Add M&Ms perpendicular to the black frosting line, pushing them in at least to the halfway point so that they resemble a bulb on a string of Christmas lights!
Step back, give yourself a high-five, and admire your adorable cupcakes!
