Peanut Butter and Jelly Mug Cake

It’s peanut butter and jelly time! After so many different versions of peanut butter mug cake, it was time to make a peanut butter and jelly version.

Okay it’s actually a peanut butter and jam version because I had this delicious homemade jam gifted to me, but you can use jelly too.

I originally thought it would be nice if the jam stayed in the middle, creating a nice surprise when you dig in. But when it cooked, the jam burst through. I actually like how it looks with the jam bubbling over.

I fiddled around again with the peanut butter cake, this time creating an easy eggless version. Though you can make a peanut butter and jelly version with my previous peanut butter mug cake incarnations too.

  1. Wow! What are you trying to do to me?! Your mug cakes ROCK and this is no exception! Wow…..awesome!

  2. I’m going to try this right now! lol Your mug cakes always turn out yummy!!

  3. I just tried this, it is delicious. But it definitely needs more than one minutes in the microwave. I kept it for 2 minutes until it rose.

    • I think it depends on the microwave. Mine is done at 1 minute. If i did 2, it would burn. But I’m glad you found the ideal time for yours.

  4. I used natural peanut butter. Seemed kind of underdone. Maybe I should have baked it longer as suggested above… but maybe it was the natural PB?

    • I think it’s the natural PB. The consistency is different so I’ve found it doesn’t work the same. I don’t usually have natural PB in the house. I’m sure there is a way to make it work, but the recipe would need tweaking.

  5. I love this recipe! So moist and delicious!

  6. I’m really excited to try this! I’m so glad I found thhis recipe & lovely blog by the way 🙂

  7. wow! so yummy! I will do this again 🙂 thank you!

  8. Wow this was great! Came across your website searching for mug cakes. Now I can’t wait to try your other mug cakes!

  9. I made this with Nutella instead of jam — yummy!

  10. Hi I happened upon your page from notcot.com. I love this recipe! I’m not even a huge PB&J fan but this is excellent. It’s moist although I should have left it in the microwave for about another 30 seconds. Still I like how moist it was. And it tasted great, more than most peanut butter desserts I’ve had. 🙂

  11. I made this with two tablespoons of peanut butter instead of three. It was still very peanut buttery and delicious! I had to leave it in the microwave for a bit longer, too. Still, it turned out great.

  12. Should I use the same amount of Bisquick or self rising flour? I don’t have any baking powder. This sounds really yummy!

  13. Wow! This looks delicious im about to try it out! Never thought to make a mug cake like this. I swear I love your mug cakes????

  14. Googled and found this pb&j mug today! I love it! Soooo good! Will make often. 🙂 Have a Samsung 1000 watt microwave. Did have to add an extra 30 seconds, but no biggie. End result was amazing! Thanks!
