Keto Chocolate Mug Cake
A rich, single-serving chocolate mug cake that goes from craving to spoon in 90 seconds. Moist, fudgy, and only a few net carbs, made in the microwave.
Dessert for one, in ninety seconds
The mug cake exists for a specific moment: it is late, you want something chocolatey, and you are not about to heat an oven. This keto version delivers a warm, tender cake with a molten center using one mug and a microwave.
The secret to keeping it moist rather than rubbery is a little sour cream or heavy cream and pulling it out the instant the top springs back. Overcook a mug cake by even ten seconds and it turns dry, so err on the side of gooey.
- Whisk the egg in thoroughly so there are no streaks
- Stop microwaving as soon as the top is just set
- Eat it warm, straight from the mug

Recipe FAQ
Can I bake it in the oven instead?
Yes. Pour the batter into a small oven-safe ramekin and bake at 350 degrees Fahrenheit for about 12 to 15 minutes, until the top springs back. The texture is a little more even than the microwave version.
Why did my mug cake turn out rubbery?
Overcooking is almost always the cause. Microwaves vary, so start checking at 60 seconds and pull it the moment the surface is set. A residual gooey center is normal and finishes cooking as it rests.
