100 CALORIE CHOCOLATE MUG CAKE

100 Calorie Chocolate Mug Cake is made with simple ingredients like flour, cocoa powder, sweetener, milk, coconut oil, and vanilla for a quick, fudgy chocolate treat ready in just 30 seconds!

This mug cake comes together in just minutes and is packed with rich chocolate flavor! I prefer cooking mine for 30 seconds to keep it extra fudgy, but you can go closer to 35 seconds if you prefer a slightly more cake-like texture.

Don’t let the small amount of batter fool you—it’s the perfect size for a single-serving sweet treat and will rise to fill about half of a standard mug once cooked. Finish it with a sprinkle of powdered sugar for a little extra sweetness. If you’re craving chocolate and need a dessert fast, this little mug cake is pure perfection!

Ingredients for Low Calorie Chocolate Mug Cake

Flour – Provides the structure for the mug cake and gives it a soft, cake-like texture.

Sweetener – Adds sweetness while keeping the recipe lower in calories when using a sugar substitute like Stevia or erythritol.

Cocoa Powder – Creates the rich chocolate flavor and deep cocoa taste in every bite.

Baking Powder – Helps the mug cake rise and become light and fluffy without needing eggs.

Milk – Adds moisture and helps create a smooth, fudgy cake batter.

Coconut Oil – Adds richness and helps keep the cake tender and moist.

Vanilla Extract – Enhances the chocolate flavor and adds a warm, sweet aroma.

Salt – Balances the sweetness and brings out the chocolate flavor.

How to make Chocolate Mug Cake

How long is this Chocolate Mug Cake good for?

This mug cake is best enjoyed fresh right after making it. Since it’s a quick, single-serving dessert that comes together in just 30 seconds, there’s really no need to store or freeze it—it’s best made when the chocolate craving hits!

What is the best cocoa powder?

I prefer to use either Premium Cocoa or Ghirardelli cocoa powder for this chocolate mug cake recipe. When the recipe only calls for a few ingredients, each one really counts! If the flavor of the cocoa powder you use isn’t top notch to begin with, the flavor in your mug cake will reflect that. So add one of the names I mentioned to your grocery list and pick up a container next time you’re at the store.

How many calories are in Chocolate Mug Cake?

I’ve calculated this mug cake recipe to be 110-158 calories, depending on your exact ingredients. Here is an image showing how I calculated that amount. You must use a no calorie sweetener to get the calorie count this low. You can swap out the regular milk for almond milk if you’d like. I love the flavor of coconut oil in this recipe, but using canola oil doesn’t change the calorie count at all.

How to make Chocolate Mug Cake without an egg?

Regular chocolate cake recipes contain an egg, yet we opted to leave the egg out so that it will cook faster. We added baking powder as a leavening agent, that is, it helps the cake to puff up and rise.
