Watching my calories doesn’t mean I say goodbye to sweets. Quite the contrary, actually.

My low calorie mug cake has been a staple in our house for quite a while. It’s easy to make and allows me to satisfy my chocolate cravings without going overboard.

Why I love this recipe

  • Microwave and oven instructions. I prefer the microwave method since it’s quick, but if I’m making 2-3 mug cakes at a time, I’ll typically use the oven. So, I included instructions for both.
  • Secretly diet-friendly. Without even trying, this mug cake is dairy-free, vegan, AND easy to make gluten-free or low-carb if needed.
  • It’s just so easy. Just mix all the ingredients together and pop it in the microwave. One minute later, and voila! A mini chocolate cake all for yourself.
  • Customizable. This recipe has plenty of wiggle room to swap the ingredients or change the flavor.

Ingredients needed

  • All-purpose flour. Also known as plain flour. Be sure to sift it thoroughly if your flour has clumps.
  • Sugar OR sugar substitute. To keep the calories super low and the mug cake sugar-free, opt for a sugar substitute (granulated). If you are fine with some sugar, any works- brown, white, coconut sugar, etc.
  • Cocoa Powder. To give the mug cake the chocolate flavor, use good-quality cocoa powder to really bring out the flavor.
  • Baking soda. To give the mug cake some rise and texture!
  • Salt. Brings out the sweetness, especially in cakes.
  • Oil of choice. For the rich texture of the cake. Oil also replaces the need for any butter or margarine.
  • White vinegar. It acts as a leavening agent, especially when mixedwith baking soda.
  • Vanilla extract. A must for any baked good or cake!
  • Water. To bind the ingredients. I also tested using unsweetened almond milk, but I didn’t notice a big flavor difference, so I used water to keep the calories lower.
  • Espresso powder. Optional, but I find it enhances the chocolate flavor without imparting strong coffee flavor.
  • Mini chocolate chips. Another optional mix-in, but as you can imagine, chocolate chips make everything taste better!

How to make this in the oven

If you’d rather make the healthy mug cake in the oven, you certainly can. Simply grease an oven-safe ramekin or small baking dish (4 or 6 inches) with cooking spray. Make the cake batter and pour it into the ramekin. Bake for 8-10 minutes or until a toothpick comes out mostly clean. Let it sit for a minute before enjoying.

Arman’s recipe tips

  • Avoid overcooking. Everyone’s microwave models differ, so I suggest microwaving the mug cakes in 30-second intervals. After a minute, if the cake feels slightly soft, let it sit for 30 seconds and see if it firms up. If not, continue microwaving in 15-second intervals until done.
  • Use a bigger mug or cereal bowl if you’re worried the cake will overflow as it expands.
  • If the batter is too thick, add a splash of milk.

Variations

  • Make it extra gooey. Add an additional 2 tablespoons of water and reduce the cooking time to 45 seconds or until the tops are just barely done.
  • Cut the carbs. Use a keto brown sugar substitute and sugar-free chocolate chips.
  • Make it fat-free. Swap the oil for unsweetened applesauce.
  • Enhance the flavor. Fold in ½ teaspoon of vanilla extract or top the cake with a pinch of flaky sea salt.

  • 2 tablespoon all-purpose flour gluten-free, if necessary
  • 2 tablespoon granulated sweetener of choice sugar or sugar substitute
  • 2 teaspoon cocoa powder
  • 1/16 teaspoon salt
  • 1/8 teaspoon baking soda
  • 1/4 teaspoon espresso powder optional
  • 1 teaspoon oil of choice vegetable, sunflower, coconut, etc.
  • 1/2 teaspoon white vinegar scant 1/2 teaspoon * See notes

  • 2 tablespoon water
  • 1-2 tablespoon chocolate chips of choice optional

Instructions

  • Grease a microwave-safe bowl or ramekin generously with cooking spray.

  • Add your dry ingredients and mix well. Add the rest of the ingredients and mix until fully incorporated. If using chocolate chips, fold them through.

  • Microwave for 1-2 minutes, or until done. Remove from the microwave and let sit for 30 seconds, before enjoying.

Oven Instructions

  • Preheat the oven to 180C/350F. Grease an oven-safe dish or ramekin (4-6 inches).

  • Add your dry ingredients and mix well. Add the rest of the ingredients and mix until fully incorporated. If using chocolate chips, fold them through.

  • Bake for 8-10 minutes, or until the cake looks done. Remove from the oven and let sit for 30 seconds, before enjoying.

Notes

* Try not to fill the 1/2 teaspoon full of the vinegar.

The chocolate mug cake is made without eggs, so it is okay if your mug cake is a little undercooked.

For a moist chocolate mug cake, add an extra 1-2 tablespoons of water and add chocolate chips into the center of the mug cake.
