There is nothing better than a foolproof no-bake dessert and this peanut butter mug cake is the best of them all. Jam packed full of peanut butter and irresistibly moist, you will want this mug cake recipe every night of the week!
There isn't anything better than being able to hang out and relax with a bit of cake at any time a craving strikes. It's also something that helps me get through times when I just don't want to do anything as a way to reward me for getting things done anyway. Mug cake recipes are life savers.
This peanut butter mug cake is exceptionally good for those particular moments I need a healthy dose of peanut butter.... and maybe some chocolate chips thrown in for good measure. Or ice cream, maybe.
Is Peanut Butter Mug Cake Eggless?
Yes! Since the cake is so small, you don't need much to add to the structure or moisture of the cake. This peanut butter mug cake is naturally eggless.
Can You Make Mug Cake with Other Nut Butters?
Yes, you can substitute the peanut butter for any type of nut butter you like! Just know that the different nut butters will affect the final flavor of the cake. I have never tried it with anything outside of peanut butter and don't guarantee you will like it. If you have an allergy to peanut butter or nut butters in general, you can try my vanilla mug cake or black forest mug brownie.
You can also experiment with using things like cookie butter. Please note that you will need to cut down, or even eliminate the sugar in the cake recipe altogether to keep it from being cloyingly sweet.
Can You Make Mug Cake Without Baking Powder?
The baking powder gives the peanut butter mug cake lift and makes it nice and fluffy. Saying that, since the mug cake is so small, you can probably get away with not using the baking powder if you don't have any. Just be aware that your cake might be a little more dense than if you did use it.
Can You Make Mug Cake in a Bowl?
Yes, if your bowl is microwave-safe and can fit at least 12 ounces, you should be more than fine to use a bowl. In a pinch, you can use pretty much any microwave-safe container that is big enough to keep the batter from overflowing.
Can You Make Mug Cakes in the Oven?
Yes, you can make your peanut butter mug cake in the oven. If your mug is microwave-safe, it may be oven-safe too. Just double check before you use it! Heat the oven to 350 degrees F and start checking the mug cake after about 10 - 13 minutes. It should be ready when a toothpick comes out with only a couple of crumbs sticking to it.
