Best Chocolate Cupcake Recipe – Really.

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. I’m crazy, I literally dream about these things.

You can easily double this recipe, it is actually half of the original recipe. 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 :).

    • 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.

  • Kelly Anthony: Hi there ???????????? 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: I read (and still read) a lot of Cook’s Illustrated books and I also liked Bakewise (as far as info went). March 6, 2017 at 6:27pm Reply

      • Kelly Anthony: Love Cooks Illustrated ???? I’ll check out Bakewise! Thank you!! March 7, 2017 at 5:15am Reply

        • Carol C.: I made the cupcakes today and they are delicious even without the frosting! Thank you! I wonder why you use baking soda instead of baking powder for your recipes… is there a specific reason for it? March 10, 2018 at 8:57pm Reply

    • Beth Bennett: Hi Kelly and Jaclyn,
      I have a great book, The Cake Bible, by Rose Levy Beranbaum. Very scientific, I like her how’s and whys of substituting different fats and chocolates, etc. I also like her recipes for stabilizing whipped cream, so you can use it for frosting cakes and things, without it collapsing all over the place. And it tastes delicious!
      But Jaclyn, your recipe for chocolate buttercream is by far the best chocolate frosting in the world. And I have made your Lemon Blueberry layer cake so many times, and it is a favorite of people who think they don’t like lemon as a flavor. It is one of the best cakes out there. I always decorate it with the sliced lemons and blueberries like in your photos, (well, kind of like in your photos) and people are always impressed! October 20, 2017 at 10:15pm Reply

      • Jaclyn: Thanks for the info and kind words Beth! October 24, 2017 at 12:13pm Reply
