    These turned out perfect! I made them today- added a dozen or so frostings - and everybody loved them. So easy, so moist, so yummy! *_*

    I've made these last week for a friends birthday. It was perfect, especially with my homemade salted caramel frosting, it really compliments each other. I did 2 other frosting which are lemon orange and barcardi flavoured. Salted caramel frosting is well liked by all.

    Made these, but with mocha buttercream and ended up with people placing orders for them...yikes!

    These Easy One-Bowl Chocolate Cupcakes are awesome Sarah! Even my husband said, that they are delicious! Now for the "Swiss Buttercream Icing" What's the secret, it turned out as a flop!

    These cupcakes were a great hit, the frosting made it extra fancy and delicious at the same time I gotta say I never made cupcakes that tasted this yummy!!!

    This recipe was the best cupcake recipe I made, especially the frosting that made them look fancy and still taste delicious, these cupcakes was surely a hit!

    This proved to be super easy and extra yummy. We made it in cooking class yesterday and the kids loved it. Also we did the frosting and it swirled....yeah. But I would not use a zip lock bag, it burst after the first cupcake. But it still was extra cool!

    These cupcakes are delicious! I added the warm water and was a bit skeptical because the batter was very runny (I'm used to very thick batter and resulting very dense cupcakes) but the cupcakes came out great. Very light but not at all dry - very moist. I used Martha's recipe for Billy's chocolate buttercream (adding a teaspoon of almond extract to make it chocolate almond buttercream). Delicious! My boyfriend inhaled them!

    These cupcakes are fantastic! I made them for my sister-in-laws birthday and frosted them with a chocolate/white buttercream swirl as suggested. One thing I noticed though, the 1 1/2 c warm water added in the video is not in the recipe. I was glad I watched the video or I would have ended up with thick, brownie like cupcakes instead of moist, cake ones;)

    The cupcakes look so good can't wait to make them. Please tell me about the recipe for the icing. Thank you

    The water is listed in the directions but not in the list of ingredients. It is assumed that we all have water available to us.

  • 15 Mar, 2013

    Like others, the video shows adding water but not in recipe. Please confirm printed recipe is accurate.

    There is NO water in the list of ingredients..isn't that a lot of liquid beside the buttermilk?

    The cupcakes look yummy, but noticed the 1 1/2 cups of warm water is not in the list of ingredients...should be sure to add.
