This low carb mug cake is a simple, single-serving keto dessert that’s perfect when you want something sweet and chocolatey. Microwave mug cakes are super easy to make and take just minutes from start to finish.

How Many Carbs In A Mug Cake?

Keto mug cake is a low-carb version of regular chocolate cake, similar to this version of low-carb keto chocolate chip cookies that’s perfect for a low carb diet. This chocolate cake recipe is made with coconut flour and cocoa powder, so it has no sugar or gluten. This single serve cake comes in at 17 grams of carbs and 7 grams of fiber. That gives this mug cake a 10 net carbs total.

What Is Coconut Flour?

Coconut flour is a low-carb alternative to traditional wheat flour which makes it great for the keto diet. It contains medium-chain triglycerides (MCTs) which have been linked to weight loss. MCTs are quickly metabolized and turned into energy rather than being stored as fat. Coconut flour also doesn’t contain gluten or sugar.

What Kind of Toppings Can I Put on a Mug Cake?

  • Maple Syrup
  • Peanut Butter
  • Scoop of Vanilla Ice Cream (Keto Vanilla Ice Cream Recipe)
  • Fresh Berries
  • Dark Chocolate (sugar-free)
  • Whipped Cream (made with Heavy Cream)
  • Walnuts
  • Peanuts
  • Pecans
  • Almonds
  • Powdered Sugar (Keto-friendly such as Swerve)

How to Store Leftovers

While this is considered to be a single serving, sometimes, this cake might be more than you want to eat at one time or you simply get full. If you find that you have leftovers of the cake, you can wrap the mug tightly. You can leave the cake sitting at room temperature for a day or two or even store it in the refrigerator.

Reheating Leftovers

This cake will always taste best when it is made fresh. If you find that you have leftovers, you might want to reheat it give that fresh from the oven taste. You can reheat it in the microwave. Start at 30 seconds and if you want it warmer, you can always heat if or longer. Overheating can result in dryness.

If you are reheating the microwave mug cake and it does dry out, adding whipped cream or keto ice cream can help.

Variations to This Easy Chocolate Dessert

You can add a few other things to this cake for a variety. You can add different extracts to give it a different flavor. Almond extract is always a favorite. You can also add a few chocolate chips or sugar free caramel chips to the inside of the cake.

You can also add pieces of other sugar free candies to the inside to give it a different flavor.
