100 Calorie Mug Cake Ingredients:
Here are all the ingredients you need to make this low calorie chocolate mug cake:
- Plain Flour – All-purpose, plain flour.
- Calorie-Free Sweetener – I use a sugar-free (and calorie-free) sweetener Swerve. You can also use white or brown sugar, honey, or maple syrup to sweeten the mug cake but this will increase the calorie count.
- Cocoa Powder – Use unsweetened cocoa powder.
- Baking powder
- Almond Milk – use any milk you like such as regular milk, soy milk, cashew milk, or coconut milk. I like using unsweetened almond milk.
- Oil – Any oil such as vegetable oil, olive oil, or coconut oil.
- Vanilla extract
To top:
1 tsp chocolate chips (optional)

How to make the 100 calorie chocolate mug cake:
Step 1:Add all of the dry ingredients into a microwave-safe mug and mix to combine. Then add in the wet ingredients and stir until a thick chocolate batter forms. The mug cake batter should look like this:

Step 2: Place the mug into your microwave and microwave for 45 to 60 seconds (depending on your microwave wattage). The cake should be just slightly undercooked to avoid making it dry and tough. I recommend starting with 45 seconds, testing it and then adding additional time if needed.
Step 3: Top with 1 tsp of chocolate chips if you like and serve immediately!
