One-Bowl Chocolate Cake

This cake mixes up quickly and bakes while we enjoy our dinner. My son, David, loves to help decorate it. —Coleen Martin, Brookfield, Wisconsin

    Wonderful cake! I put a shooter of Rum Chata in the frosting and it was great! Will make this again!

    So easy, so moist, and so good. This cake doesn't rise super high, but you can see that by the picture shown. We enjoy it with various frosting flavors: chocolate, peanut butter, fluffy white.... good any way you top it! One reviewer suggested adding vanilla, which I like as well. Enhances the flavor more.

    I always go to Taste of Home first when searching for a recipe, and this one definitely is Not a disappointment. It is very moist and light. The icing is perfect. I bake a lot for bake sales and this i s a winner.

    I’ve made this twice now and it is delicious and moist and disappears quickly! Very easy recipe as is. I made the accompanying frosting that was with the recipe and it was the perfect amount for the top of the cake. Will definitely make again.

    I just make this today and love how simple it is to make, one bowl, yes! What I don't love is how flat the flavor is, do yourself a favor and add a teaspoon of vanilla and sub out the water with some fresh brewed coffee. I'm sorry I didn't do that, I have made this recipe before and those changes will make you very happy. Unfortunately I forgot about it this time.

    I have this recipe from an old church recipe book from the ladies. You think the water and shortening is too much but it isn't, cake comes out perfect.

    Excellent cake, I also add 1 teaspoon vanilla and instead of just 1 cup hot water, I use either half coffee

    I made this for my daughter who likes dark, moist, chocolate cake. She said it was just right. One change I made was that I added a teaspoon of vanilla. Another thing I did, that I wouldn’t recommend, I made it into a two layer cake. Perhaps because we are at high allude, but it didnt the cake didn’t stand up well as a layer. It was so moist that it wanted to fall apart after it was decorated. Next time I’ll leave it as a 9x13.
