3-Ingredient Flourless Mug Cake

I have two chocolate mug cake recipes on my blog already and I’m excited to share with you a third! This 3-minute mug cake recipe is completely different from the other two.

This hot chocolate bomb mug cake is SUPER decadent and chocolatey and will totally satisfy your sweet tooth. It’s made with wheat flour and is not gluten-free or flourless.

My healthy chocolate mug cake IS flourless and gluten-free. It uses ground almonds for the “flour” and is protein-packed and so full of flavor. It isn’t easily made keto because of one of the ingredients.

If you love almond flour recipes, try this almond flour mug cake – it’s SO good and healthy too!

This 3-ingredient mug cake is:


Refined sugar free

Oil free

And there’s an easy keto mug cake version too!

3-Ingredient Mug Cake Ingredients

Well, there are three of them! 🙂

An egg

Cocoa powder

Maple syrup

The egg is essential in this microwave cake recipe – there isn’t really a good sub for it.

The cocoa powder – also essential in a healthy chocolate cake recipe.

Maple syrup is my favorite sweetener to use in this recipe, but here we have options! If you follow a sugar-free, low sugar, diabetic diet, or keto diet, I have some subs for you – see below!

Tips and Substitutions for this Gluten-free Chocolate Mug Cake

My favorite sweetener is pure maple syrup. It is so much yummier than table syrup, but if that’s what you have you can use it in a pinch. Honey works too but I preferred the flavor with maple syrup.

You can also use 2 tablespoons of chocolate sauce or chocolate syrup instead of the maple syrup.

If you follow the Keto diet, sub the maple syrup with Lakanto maple flavored syrup.

(Psst…if you’re Keto, you HAVE to try this Keto mug bread – it is everything!!)

For another sugar-free substitution for the maple syrup you can use sugar-free chocolate sauce.

Top this Flourless Chocolate Mug Cake with:
  • Whipped cream
  • Melted chocolate chips
  • Chocolate sauce/ sugar-free chocolate sauce
  • Ice cream
  • Sprinkles (we do a lot of sprinkles over here with a 5-year-old!)
  • Caramel sauce (my favorite is this date-sweetened caramel sauce – OMG)
