This 3 ingredient peanut butter mug cake is an easy, quick and no-fuss treat. It is flourless, fudgy, made in the microwave in just 1 minute, and so good!
Transfer the batter into a microwave-safe mug or ramekin. Scatter chocolate chips on top (if using).
1 teaspoon chocolate chips
Microwave for 45 seconds-1 minute. Remove from the microwave and allow it to sit for a minute before eating.
Notes
The mug that you use must be sturdy and heat-resistant (you don't want your cup to crack) but also not become excessively hot to hold the mug cake while it is being baked in the microwave.
To remove the mug from the microwave, place an oven glove or a tea towel around the handle. Allow the mug cake to cool for a few minutes before cutting into it.
Do not overcook! It takes no longer a minute to bake this dish, and overcooking it will result in a dry and hard mug cake opposite to the fudgy, rich, and moist one that we are trying to achieve.
Variations
An easier substitute for granulated sugar is brown sugar.
There are many options for toppings you may choose from other than chocolate chips. For soft and creamy toppings, you may top your mug cake with whip cream. If you want a pillowy texture, you may consider using marshmallows instead. However, if you prefer your homemade mug cake as it is, you don't have to add any toppings at all.
