  1. 4 stars
    Another great recipe. I made this with the Buttermilk Chocolate cake, both were fantastic. The cake batter was thinner than I anticipated but the cake worked.

    I have learned so much and gain a lot of baking confidence from your recipes and other posts. Thank you!

  2. This recipe sounds delicious! Can corn syrup be added to it like in your American Buttercream recipe?

  3. Just an FYI. You have 2 oz. of cocoa equaling 1/2 cup. That’s not correct. 2 oz. is 1/4 cup.

  4. Can anyone make a chocolate frosting without using powdered sugar?I’m hunting one that’s made with real sugar and cocoa powder

    1. @Eileen Gray, thank you. I’m going to try both recipes. Trying to find a recipe for my mom’s frosting that my dad and I used to fight over. I would cut away the chocolate cake from my slice and leave the frosting for last. My dad would always try to take my frosting. Great memories.
