This flourless almond butter mug cake is just four ingredients and ready in minutes. It is fluffy, moist and you won't believe it doesn't contain any flour.
Combine all ingredients into an oversized microwave-safe mug. This cake does rise quite a bit, so make sure your mug is at least 12 oz.
Mix with a small whisk until batter is completely smooth. Make sure you whisk until all the egg has fully been mixed in, otherwise it won't bake properly. You should have an even, brown batter. It really helps if you are using a whisk rather than a fork.
Microwave for about 1 minute 20 seconds. Let cake cool a few minutes before eating. If desired, you can also top with powdered sugar or syrup.
Notes
I prefer to use Jif brand because of its consistency.
I find there's just enough sugar in this cake, but if you have more of a sweet tooth you can increase the amount.
