Protein Chocolate Chips Mug Cake

Sharing is caring!

Skinny protein mug cake with gooey chocolate chips. A fluffy and delicious mug cake that has 27 gr of protein. Also, I have a keto version that is just as good.

Lately, you’ve probably noticed that I’m into the mug cake trend — I know that this trend has been going on for a few years, I’m always late in food trends XD. I just can’t get enough of their convenience.

I’ve already made chocolate mug cake and vanilla mug cake in this blog. However, in my daily life, I can’t be eating regular mug cakes — full of sugar — every day. I save them for specific times.

But, what happens when my heart says “another mug cake, please” and my waistline tells me“drink a protein shake, for the love of God, woman!”? I make a skinny protein mug cake and EVERYBODY is happy.

How do you make skinny protein mug cake?

Easy peasy.

It takes the same amount of time than regular mug cakes. It’s all about making small changes.

IngredientHealthy Substitution
Sugar Low-calorie sweetener
Flour Whole wheat flour + vanilla whey protein powder
Whole milk Soy or almond milk

Simple swaps that lower the calorie intake without sacrificing the flavor.

You can eliminate the egg and add an extra ½ tsp of coconut oil to balance the oil that the yolk provides. Be aware that the cake will be less fluffy and more compact, but the flavor remains the same.

Can I make a keto protein mug?

Of course, you can swap the whole wheat flour with coconut flour and the mug cake will be completely keto.

I prefer the consistency of coconut flour much more than the almond flour’s.

Almond flour gives a compact and kind of dry mug cake. Coconut flour gives a lighter and fluffier cake. Especially when you add coconut oil. Fluffy and moist at the same time.

What type of whey protein do I use?

I like to use Isolated vanilla whey protein. My ultimate favorite brand is Naked Nutrition Whey Vanilla.

This is one of the cleanest proteins in the market. They use grass fed cows that are raised in a sustainable way.

Also, this protein only has three ingredients: Grass Fed Whey Protein, Vanilla, and Organic Coconut Sugar. That’s it! no artificial sweeteners of chemicals.

If you are struggling with hormonal imbalances — such as estrogen dominance — this is a protein that is rBGH and rBST clean. Plus gluten-free and soy-free.

The only downside is that is a bit bland in flavor. But if you want 100% clean and healthy products you must sacrifice the artificial flavors. I add a bit of natural vanilla essence (1/2 tsp) to the mug cake to add extra vanilla flavor to the cake.

But I also love to use Naked Nutrition isolated vanilla protein for pancakes, muffins, and now mug cakes. 

How many calories are there in this whey protein mug cake?

One portion if this mug cake has approximately 350 calories. The good part is that it provides 27 grams of protein (if you use the egg).

It’s a great snack before and after working out. Especially if you are doing weight lifting. I like it for my leg days when I need an extra boost to endure the training.


  • Candied pecans
  • Walnuts
  • Chocolate chips (my absolute fav) 
  • Macadamia nuts
  • Peanut butter (extra protein and healthy fats)
