What Makes This Recipe Great

Who wouldn’t want cake for breakfast?! Especially when that cake is full of nutritious, healthy ingredients without the added frosting, sugar, and butter. Whether you’re craving a sweet morning treat or looking for an easy dessert recipe, this recipe has it all.

I love this healthy mug cake recipe because it’s made with simple, dairy-free and gluten-free ingredients, has nearly 40 grams of protein, and is so filling. 

My favorite part is that all you have to do is dump all your ingredients into a mug, microwave it for 2 minutes, and you have a delicious protein-packed dessert, breakfast, or snack. You’ll probably spend more time picking out your toppings!

Ingredient Notes

recipe ingredients in nesting bowls and labeled
  • Egg: I have not tried this recipe egg-free, but a flax egg should work well!
  • Maple Syrup: Use pure maple syrup. I love this natural sweetener because it adds sweetness but isn’t refined sugar.   
  • Coconut Oil: You can also use ghee or vegan butter. 
  • Vanilla Extract
  • Flour: This recipe uses a blend of almond flour and coconut flour. If preferred, you can swap for 1/4 cup oat flour or another gluten-free flour blend but it will have less protein (almond flour has lots of protein!). 
  • Cacao Powder: Cacao powder is rich in antioxidants and adds a deep chocolate flavor to this protein mug cake. You can swap for unsweetened cocoa powder if that’s what you have on hand. 
  • Protein Powder: Use your favorite chocolate protein powder or vanilla protein powder. Many brands make dairy-free, gluten-free versions, so check for those if you have sensitivities.  
  • Dairy-Free Chocolate Chips: I like the brand Enjoy Life. They make dairy-free dark chocolate chips that are also nut-free and gluten-free. You can find them online or in your local grocery store. 
  • Baking Powder
  • Sea Salt

Mary’s Tips & Tricks

Oven Method

If you don’t have a microwave, or don’t want to use it, follow these instructions for an oven-baked protein mug cake.

  1. Preheat your oven to 350 degrees F.
  2. Combine ingredients in an oven-safe ramekin or mug, or another oven-safe dish.
  3. Bake for 18-20 minutes.
  4. Let cool for a few minutes and top with your toppings of choice.

Toppings

If you want to jazz up your mug cake, here are some ideas for fun toppings:

  • Extra Chocolate Chips
  • Peanut Butter
  • Dairy-Free Whipped Cream
  • Strawberries, Blueberries, Raspberries, and/or Blackberries
  • Gluten-Free Rainbow Sprinkles

Variations & Substitutions 

  • If you want your protein mug cake to be sugar-free, try a keto-friendly maple syrup alternative. 
  • You can use any flavor of protein powder you want. Switching it up with strawberry protein powder or a seasonal flavor would be really yummy!
  • Make sure you use the proper-sized mug. If your mug is too small it could spill over. 
  • You can also use a ramekin instead of a mug in you prefer. 
  • This doubles as a gluten-free mug cake recipe. If you aren’t gluten-free, you can swap a regular all-purpose flour. Just keep in mind the nutrition facts will change. 
  • Make one mug cake and split it in half for the kids. This will give them a tasty, protein-packed breakfast. I promise they will gobble it up!
  • Need a healthy birthday cake idea? Top with sprinkles and a scoop of dairy-free vanilla ice cream!

Storage Tips

  • This protein mug cake recipe is intended for eating right away. I don’t recommend storing it for later. They’re single-serve, but if you feel like it’s too much, you can split the finished mug cake into two and share it with a family member.

Recipe FAQs

Is this recipe vegan?

It contains eggs so it is not vegan. If you want to try using an egg replacement/substitute, you can! You can try a storebought egg replacement, or a chia or flax egg. With an egg substitute, and vegan butter or coconut oil, this protein mug cake would be vegan. 

What is the best protein powder?

I personally look for dairy-free, gluten-free, and soy-free options for my protein powder. I like the brands Be Well By Kelly and Truvani, but there are so many delicious options out there. If you want protein powder in bulk, Costco sells the Orgain brand, which is vegan and gluten-free.
