Healthy? A cake? Ok so maybe it's not hitting the charts as the healthiest thing you've eaten BUT, it does have some good perks. Instead of using regular white sugar, we use honey. You still get that sweet flavor, but with a natural sweetener instead.
How to make Chocolate Peanut Butter Molten Mug Cake
Making Chocolate Peanut Butter Molten mug cakes is so easy!
First you start by adding flour, coco powder, and baking powder into a mug. With a fork, mix the dry ingredients together.
Then add your wet ingredients, milk, egg, honey, and melted butter. Mix altogether until smooth. I always have a hard time getting every flour bubble out, and it still taste great.
Put a dollop of peanut butter in the middle of the batter and sprinkle with chocolate chips. Don't push down the peanut butter or chocolate chips, they will naturally go down as the cake cooks.
Put your mug and batter in the microwave on a napkin. The napkin will catch any over flowing batter and make for easier clean up. Cook the mug cake for about 60 seconds. Make sure to adjust the time depending on your microwave. If the mug cake is cooked too long it will have a spongy, less desired, texture.
Enjoy your delicious Chocolate Peanut Butter Molten Mug Cake!
How to get the perfect texture!
All microwaves are different. Some cook hot, and some take longer. That being said, your mug cake may be ready before the minutes up, or may need a little extra time. My microwave runs high and so my mug cake is perfect at 55 seconds.
A good way to tell if your cake is ready is by how sticky the top is. If it looks a little moist and sticks to your finger, your cake is perfectly cooked. If it looks dry and has no stick, you've over cooked your mini cake and the texture will be a little spongy. Don't worry, it will still taste great but next time adjust the cook time.
Why just an egg white?
Regular sized cakes often call for one, maybe two, eggs. Often mug cake recipes call for a whole egg and we feel like that is too much for a small cake. By doing just an egg white, it helps maintain a soft, moist, texture instead of a spongy texture.
Save the egg yolk and add it to your breakfast eggs the next day!
This recipe is not made for the oven! The cook times do not convert over.

I love this healthier single serve mug cake. The molten peanut butter is a fun twist to tradition mug cakes. A perfect late night snack without overloading on sugar but satisfies the sweet tooth.
