  1. In a large microwavable mug, mix together the flour, baking powder, and salt.
  2. Add the peanut butter, milk, maple syrup, and vanilla extract. Mix until just combined. Be careful not to over-mix.
  3. Add the jam, and gently swirl it into the batter.
  4. Microwave on high (800 - 900 W) for 2 minutes, or until a toothpick inserted into the centre comes out clean. The cooking time may vary depending on your microwave and settings. If the cake isn't cooked through yet, simply place it back in the microwave at intervals of 15 seconds until done.
  5. Let the mug cake cool slightly, add your desired toppings, and enjoy!


  • Take care when removing the mug from the microwave. It might be very hot.
  • If preferred, bake it in the oven at 350°F (180°C) for 15 - 25 minutes, or until a toothpick inserted into the centre comes out clean. Just be sure to use an oven-safe baking dish.


  • This dessert is best enjoyed immediately.
  • Transfer to an airtight container and kept in the fridge for up to 1 day.

I would love to try the recipe but not sure what would be considered as a large mug here. Can you give me some reference?

PUL Team - Sept. 27, 2021, 4:31 a.m.

Hi Jackie! Apologies for any confusion. Our mugs hold 240 mL (8 oz) in total, but a larger-sized mug will work too 🙂 We hope you enjoy the recipe if you give it a try!

I would love to make these great mug cakes but I don't have a microwave.
Is it possible with a normal oven ?
thanks from Italy

PUL Team - Sept. 26, 2021, 6:34 p.m.

Hello, Marjolein! Thanks for the question. Yes, you can bake it in the oven at around 350°F (180°C) for 15-25 minutes, or until a toothpick inserted into the centre comes out clean. Just be sure to use an oven-safe baking dish☺️

Great recipe! I added fresh berries and banana after I microwaved it. I can't wait to try the other mug cakes.
Thank you!

I love this recipe so much. I keep making it over and over again.❤️❤️ Ιt also helped me with forgoing store-bought sweets when I have late night sugar cravings. Ι personally always add a teaspoon of cocoa powder which makes it even more decadent.😋 Thanks for the great recipe and lots of love to the PUL team.💕

PUL Team - July 15, 2021, 2:44 a.m.

Such a wonderful idea to add cocoa powder! Sending lots of love back to you, Lisa ♥️

Thank you for the great site and love for plants too! The only thing is I never use microwave because it's not good for you. How could this be adapted for a normal oven?
Thanks from Canada!

Lovely question, Olena! You can bake the cake in the oven at 350°F (180°C) for 15 - 25 minutes, or until a toothpick inserted into the centre comes out clean. Just be sure to use an oven-safe baking dish 🤗

Hi Amy, thank you for the feedback! It's definitely helpful for us to work towards improving. In the meantime, opting not to print the photo (unchecking the "print image" box) and making the font smaller should help! Feel free to email us at [email protected] if you'd like any further support 🙂

Delicious mug cake recipe. Approved by me and my husband!

PUL Team - April 26, 2021, 6:21 a.m.

One of the best approvals! Thank you, Andreza😊

Maraia - April 25, 2021, 10:39 a.m.

I was so excited to try this recipe, but my cake exploded over the top of the mug 20 or 30 seconds into the cooking time. Do you have any idea what I might have done wrong? I don't know if it had to do with my mug size (I used a dish that was wider but shallower) or with my microwave, but I checked that it was at 900 watts.
Even though it made a mess, the cake itself still tasted delicious! Thanks for sharing this recipe. :)

PUL Team - April 26, 2021, 6:20 a.m.

Oh no! We're sorry to hear this, Maraia. It sounds like the dish may have been overfilled. Using a less shallow microwaveable safe dish and cooking it at a lower watt should help. We're glad it tasted delicious regardless, do let us know if this helps :D

Lorena G. - April 24, 2021, 2:49 a.m.

Delicious! My son and I loved it. Thanks !

Łucja - April 20, 2021, 2:52 p.m.

It was yummy, although a bit too peanut-butter-y for me. I'd add a bit less of it or replace it with something else or even don't add it at all but I don't know if it would work.

PUL Team - April 22, 2021, 2:33 a.m.

Hey Łucja! Thanks for sharing. You can totally add less peanut butter, switch to another nut or seed butter, or perhaps leave it out. We haven't tested it without peanut butter, but I imagine it will be blander 🙂
