The PB & J sandwich is possibly the most classic kids sandwich. So if you feel like re-living a part of your childhood in a mug, as dessert, then this is the place to be.
In a large microwavable mug, mix together the flour, baking powder, and salt. Then add the peanut butter, milk, maple syrup, and vanilla extract. Mix until just combined. Be careful not to over-mix.
Add the jam, and gently swirl it into the batter. Microwave on high (800 - 900 W) for 2 minutes*, or until a toothpick inserted into the centre comes out clean.
Let the mug cake cool slightly, add your desired toppings, and enjoy!
Notes
* The cooking time may vary depending on your microwave and settings. If uncooked after 2 minutes, microwave at 15-seconds intervals until done.
Storage
This dessert is best enjoyed immediately.

I don't have maple syrup on hand. Can I use sugar instead? Will it spoil the texture of the cake?
PUL Team - July 29, 2024, 2:15 p.m.
Hi Ritu, we imagine you could use granulated sugar instead. You might need to add a bit more milk to add moisture to the batter. Overall, the substitution might slightly alter the texture, but it shouldn't be too drastic! The mug cake should still be delicious!

Tried this in the airfryer and omg it tastes even better than I expected?! Absolutely delicious! Thank you so much for this recipe ♡ Any tip on how to prevent the batter from getting stuck to the mug? It takes alot of scraping and soaking in water to get it off
PUL Team - May 15, 2024, 3:12 a.m.
Hi Shaheela, aw it means so much that the mug cake was enjoyed! To prevent the batter from sticking to the mug, you can lightly grease the inside with a bit of oil or non-stick spray before adding the ingredients. This will make it easier to clean afterwards 😊

I love this cake. It’s quick and easy. I also made it with some healthier substitutions with whole grain flour and fruits instead of jelly. Worked quite well. But I agree with the other reviewer, the banana bread mug cake was my favorite so far.

Rajoshi - March 21, 2024, 2:13 a.m.
Would it be ok to omit baking powder? I’m not picky on texture as long as it tastes more or less the same :)
PUL Team - March 23, 2024, 6:06 p.m.
Hi Rajoshi, you can omit the baking powder if you don't mind a denser texture. The mug cake may not rise as much, but it should still taste delicious with the same flavours. Enjoy 🤗
Rajoshi - March 25, 2024, 9:13 p.m.
I went ahead and tried it without the baking powder and it was great! I did the same with banana bread in a mug as well with excellent results. Thank you!

Hey Aura, you bet! 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. We hope you enjoy the cake if you're able to give it a try 🤗

It was good but I like the banana mug cake more. This was stickier due to the PB and slightly drier. So it stuck to the gums and roof of the mouth more. Maybe some people like that. 🙂

Love this recipe! Have made it twice already. I’ve tried other peanut butter mug treats but they all ended up a bit dry and hard to get through. Some jam (I used strawberry) balances it out perfectly. I have a sweet tooth and I think this will become a go-to.

This is a tasty little treat with a great PB flavor. I swapped the AP flour with GF AP flour (I can’t eat gluten) and it turned out great. I would love a tip to boost the protein a smidge.
Also, this app is wonderful!
PUL Team - July 28, 2023, 2:08 a.m.
Hey Erin, yay so happy to hear! You could sprinkle in some nuts or seeds, or add peanut butter as a topping. We've also heard positive reviews with adding protein powder 🙂
CG - Oct. 21, 2023, 4:11 p.m.
How might I incorporate protein powder into the recipe ?
PUL Team - Oct. 22, 2023, 12:42 a.m.
We haven't tested it out ourselves, but perhaps you could add a spoon with the other dry ingredients. If the batter seems too dry you can add a touch more milk 🙂 let us know if you test it out, CG!

This PB&J mug was so comforting! I'm not usually a peanut butter lover, but I wanted something warm, soft, and sweet. This was perfect! I added some frozen blackberries to go with the jam and definitely recommend :)
Made all of the PUL mug cakes various times- they are UNFAILABLE*! Even replacing the wheat flour for rice or corn flour or mixing up the taste-giving-ingredient (chocolate, berries, banana) for whatever else is at hand - it still works perfectly and tastes glorious. *(correct word infallible)

At first, I was truly sceptic with the texture, the dough didn't seem promising but I was so wrong. It tasted so nice and I highly appreciate there is no added sugar. Also since it was the bottom of my peanut butter jar, I added a bit more milk because it had a thicker consistency but it tasted great in itself 😁

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

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 🙂
