Chocolate Cupcakes with Chocolate Buttercream Frosting


How is it that I’ve never shared a chocolate cupcake recipe with chocolate buttercream frosting before?? Okay I’ve shared lots of chocolate cupcakes with different kinds of frosting but who doesn’t love this classic combination – chocolate with more chocolate! This is has been my go-to chocolate cupcakes for years now. I created this recipe back when I was reading the how-to’s and sciences of baking books so I came up with the perfect blend and ratios to get my favorite chocolate cupcake. It is the softest, perfectly chocolaty, moist and fluffy cupcake and I dream about these things.Β 

You can easily double this recipe, it is actually half of the original recipe.Β I’m usually only making 12 cupcakes these days, it’s not very often that I need 24. But if you’ve got a room full of chocolate lovers go with 24 :). Try these out soon though, you just can’t go wrong with a classic chocolate cupcake with a rich chocolate buttercream frosting. These are made with all the good stuff – butter, sugar, cocoa, cream. Oh and that frosting tastes like fudge, if you are lucky enough to have any left over just store it in the fridge and eat it by the spoonful. Fudge I tell you.

  • Kelly Anthony: Hi there πŸ‘‹πŸΌπŸ˜Š I’m curious as to what scientific-type baking books you were reading. I’ve been on the look out for one for some time now, and so far, pretty disappointed with my choices. Wamp, wamp, wamp. Do you have one favorite? Or a few you just couldn’t live without? THanks so much!! March 5, 2017 at 6:25am Reply

    • Jaclyn: Thank you for the compliment! I believe it was a plastic Betty Crocker 1M tip lol. My tips always end up lost somehow, I think theres a metal equivalent to it I just couldn’t track mine down. They always end up crunched and misshapen by the disposal somehow too.
