Best Chocolate Cupcake Recipe

Marshmallow Stuffed Chocolate Cupcakes

Need a blue-ribbon chocolate cupcake recipe? After testing nearly every cupcake cookbook and recipe out there, my mom and I agreed this is the best chocolate cupcakes recipe. Period. Moist chocolate cake with just a few chocolate chips mixed in — Mmm Mmmmm!

Sometime between batches 423 and 425, we discovered another chocolate cupcake recipe with a marshmallow center– Brilliant! Only the cupcakes were hollow and hard.. a total disaster!

What to do? We used this favorite and created our own chocolate cupcake recipe by adding a large marshmallow after it comes out of the oven.  Be sure to cover the marshmallow completely with frosting to keep your secret. Voila! Marshmallow Stuffed Cupcakes!

Best Marshmallow Stuffed Chocolate Cupcake Recipe from


1¼ cups flour

½ cup cocoa powder

¾ teaspoon soda

¼ teaspoon salt

1 cup sugar

1/3 cup vegetable oil

1 egg

1 teaspoon vanilla

¾ cup buttermilk

½ cup semisweet chocolate chips

(12 large marshmallows)

Combine dry ingredients. Beat together sugar, oil, egg and vanilla.  Whisk in  dry ingredients and buttermilk, alternating, begining and ending with the dry ingredients. Beat until smooth.  Stir in chocolate chips.  Scoop into prepared muffin pan.  Bake at 350 for 20-25 minutes or until tops of cupcakes spring back lightly when touched.  Let cool in pan on rack for 10 minutes; remove and cool completely on rack. Frost with Chocolate Buttercream Frosting.

    Hi Amy! The semi sweet chocolate goes in the cupcake batter whole, right? we don’t melt them… I tried making this two days ago and the marshmallows didn’t melt like they were supposed to. Also, my cupcakes were dry.. Help!

    Hi, i have tried these cupcakes and everybody loves them. I had a Cutter for cupcakes that cut out a small amount in the middle Part of it, so i could fill in the marshmallow perfectly and fast enough to melt just right. Thanks a lot, I will keep doing these as our family favorites.

    • Amy Allen Johnson 03/18/2014 at 2:06 pm

      Hi Connie, I’m so glad to hear! I find that if I need to make cupcakes, these are still the go-to cupcakes in our house too!

    These look awesome! My only question is…does the marshmallow melt at all once placed in the cooled cupcake? I am really looking for a creamy center rather then hard

    • Amy Allen Johnson 11/14/2013 at 2:37 pm

      Hi Melanie, I find the marshmallows actually do melt and end up being more like a filling than “stuffed”. I start removing centers about 3 min after they come out. The steam from the cupcake melts. If you do it too soon, the cupcake may fall apart and the marshmallow turns syrupy. Wait too long and you’ll have a firm center. Also, I find the generic brand marshmallows have a lower gelatin content than Kraft Jet-Puffed. Good luck in your quest!

    I am going to try this delicious cupcake. Can I substitute the shortening for butter? Thanks so much for share this with us.

    Are your cups English or American cups? I’ll have to bring in the calculator; I’m Dutch and we only use the metric system. That won’t stop me frm making these awesome-looking cupcakes, though!

    • Amy 06/20/2013 at 3:06 pm

      Hello! I use American cups to measure the flour.
      Here’s my best guess on the main ingredient conversions
      172 g flour
      42 g cocoa powder
      5 ml baking soda
      1 ml salt
      198 g sugar
      80 mL vegetable oil
      5 mL vanilla
      177 mL buttermilk
      + a good handful of chocolate chips

      Good luck!

    Made these today for my son’s Awanas group and they are amazing! Definitely the best cupcake recipe I’ve ever made! Thank you

    • Amy 01/09/2013 at 2:19 pm

      Ooh, you just made my day! So glad to hear you enjoyed them. Which reminds me.. I haven’t made these in a while. Time to find the marshmallows!

  24. Amy 11/11/2012 at 5:35 pm

    The marshmallow does melt a bit, but it has more to do with how long you wait after they’re out of the oven and how fresh your mallows are. I’ll typically end up with the tops sticking out and they’re still hard, but the bottom is gooey-ish. Have fun!

  25. Roz 11/11/2012 at 5:27 pm

    I tried the hard/hollow version you referred to and found the same problem. Glad to see you came up with a different idea. Did the marshmallow melt and become creamy after it was inserted into the warm cupcake or pretty much just stay as a marshmallow?
