Mug cakes are magical, wonderfully easy treats to make when a sweet craving strikes. And this one definitely hit the spot! In just 1 minute, cocoa cake batter stuffed with a dollop of creamy peanut butter bakes up a fluffy, heavenly cake for two. Or one. No one’s judging here!

You just mix, pour, dollop a bit of peanut butter and zap in your microwave. Want to use another nut butter or spread? Feel free! You can swap the peanut butter for any spread, including Nutella and almond butter, or just omit it altogether.

How about an elegant (but super quick) dessert? Just grease your mug generously with cooking spray, cook as directed and pop out the cake onto a plate. Top with vanilla ice cream, or powdered sugar and berries (helloooo, Valentine). Voila! You have the EASIEST. EVER. molten cake to impress guests.

You have to try it to believe it!

    Gee, I just made this mug cake and it was delicious!!! I “discovered” mug cakes last year during the holidays and have tried a few. This was definitely the best chocolate mug cake I’ve made. (I wasn’t feeling too peanut-buttery tonight, so I left the pb out. Yes, you’re allowed to do that) This cake was very moist, and not rubbery like some mug cakes can be. (Really…if you use 2 eggs for a full-sized cake, using 1 egg for any mug cake is way too much, and that’s what an make them have that rubbery texture some people complain about!) This one is a keeper! To everyone that says they are going to try this recipe, you’ll e glad you did! It’s great!

    Just tried this and it was so good!!!!!!!!!!!! Really fudgey and delicious. Will definitely be trying this again.

  21. What temperature setting and time would you suggest if I wanted to make this in the oven instead? I was thinking 350 for 15-20 minutes?

  22. I haven’t tried it in the oven before, but I think more like 10-15 minutes would be sufficient.

  23. Finally!!!! A chocolate peanut butter mug cake that has just the right consistency!!!
    Just made it and it’s just perfect!

    I made this recipe a lot and I’ve done some modifications to it (to fit my tastes ;) ).
    I put only one tablespoon of cocoa powder, and just a little bit less than cup of milk.
    And sometimes I stuff it with nutella instead of peanut butter.

    Awesome :)

  25. I accidentally mixed the peanut butter in the batter and forgot the chocolate chips so I added them and some caramel chips to the center. It’s cooling now so we’ll see how it comes out.
