A luscious single serve soft-baked White Chocolate Macadamia Protein Cookie with a ton of protein powder and no sugar. Healthy white chocolate macadamia nut cookie is low fat and gluten free too!

I usually go for the soft cookies instead of the crispy ones, but this soft baked macadamia nut protein cookie took it to another level. Soft and even fudgy since its just half baked.

Still got that proper cookie flavor though, and a bit too addictive!

Ingredients for Half Baked White Chocolate Macadamia Protein Cookie

This single serve white chocolate protein cookie is made with a few simple and healthy ingredients, and has no flour, butter or oil and no sugar either!

Vanilla Protein Powder for healthy, whey protein cookie that’s also sugar free
I used HTLT Supps Vanilla Whey-Casein here.
Quest Nutrition Vanilla Milkshake is another option.
Peanut Butter Powder, also known as Powdered Peanut Butter. I recommend Lakanto for a sugar free version (the code HAYLSKITCHEN gives you a discount). Or you could use the one from PbFit or PB2 too.
Coconut Flour for a low carb protein mug cake
Almond Butter for the rich flavor.
I’d recommend American Dream Nut Butter Bundle up Blondie Almond Butter.
Egg Whites for extra protein
Unsweetened Almond Milk
Baking Powder

And then for the key part, White Chocolate Chips and Macadamia Nuts.

Tips to make White Chocolate Macadamia Nut Cookie with Protein Powder

This single serving white chocolate macadamia nut cookie really is a simple one with protein powder, and made in a mug or ramekin, but make sure you do all of this stuff to get is perfect.

Grease the ramekin! You want the mug cake cookie to come off easily.
Use an oven-safe mug if you need.

Don’t over-mix the batter!
Make sure you gently stir the wet and dry to combine them.
If you over-mix it, protein powder will make your low calorie cookie tough, dense and gummy.

Taste the batter and see if you need some extra sweetener. I’d recommend using stevia powder to maintain the consistency of the batter.

Don’t overbake the healthy mug cookie. The top will should be just cooked. It might look soft, but will harden when it cools a bit.
It will continue to cook when out, and you want the proper fudgy center.

Alternates for this Healthy White Chocolate Macadamia Cookie

I recommend making this healthy low calorie white chocolate macadamia cookie with the whey casein protein powder and other ingredients listed since it gives the best results.

If you need other options for the flours and such, here’s some alternatives for a healthy peanut butter protein powder mug cake for one:

Peanut Butter Powder: 2 tsp Almond Butter, and also reduce the amount of milk to maybe 2 Tbsp
I’d recommend American Dream Nut Butter Bundle up Blondie Almond Butter
Coconut flour: Try using about 3 Tbsp of Almond Flour
Almond Butter: Hazelnut Butter, Cashew Butter or Tahini; I don’t recommend peanut butter since it has a very strong taste.
Egg Whites: 3 Tbsp aquafaba (chickpea liquid). I haven’t given this a try yet though.
Almond Milk: Any other milk
