Chocolate Peanut Butter Mug Cake

I've tried different variations of these cakes for my family and this chocolate peanut butter mug cake is a winner! I have made it with almond milk and melted coconut oil, and both ways are delicious! —Angela Lively, Conroe, Texas

    Does this mug cake really have 862 calories? Wow, I should plan on eating celery and lettuce the rest of the day if that's the case! I followed the recipe closely. The cake tasted rather dry. Flavor was good, although I think I would add some vanilla if I make it again. I would include less oatmeal too. It's worth another try.

    Wow! So good, so comforting, so filling and so easy! The only change I'll make next time (and I definitely will be making this again) is to add a few more chocolate chips.

    Delicious! I made this without peanut butter because I didn’t have any I also replaced the sugar with Splenda, since I have type 2. It turned out perfect very tasty and I used real organic Cacoa chips. I plan to make this again and the next time around I am going to use coconut flour for a different taste!

    After reading the other reviews I started watching the doneness at about 1-1/2 minutes. It was done at 2 minutes, was good. Will make again.

    Microwave for 2 min not 2.30. They got hard towards the bottom. Love that they don’t have eggs so kids can lick as much as they want. I made with five kids, age 3-8 and everyone loved them. Some had peanut butter, some didn’t. We added cocoa in place of some of the flour. Everyone had their own cup and added their own ingredients. Fun time.

    Not stupendous but ok. I’m not crazy about one big glob of peanut butter in the middle. Should be spread out by teaspoons. Also, be sure to remove cake from mug immediately because it will continue baking and become dry and crumbly. I’d like to try with cinnamon and substituting berries (blueberries?) or chopped apple for chocolate chips.
