This single serve fudgy white chocolate peppermint protein mug cake 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 protein mug cake that’s also sugar free. I used Quest Nutrition Vanilla Milkshake whey-caesin protein powder for this mug cake.
Coconut Flour for a low carb protein mug cake
Egg Whites for extra protein
Unsweetened Almond Milk
Baking Powder

If you need to add more sweetness, Stevia Powder or Zero Calorie Sugar Substitute; I use Lakanto, to keep keto cinnamon mug cake sugar free; (code HAYLSKITCHEN for a discount here too)

And for the White Chocolate Peppermint Mug Cake Topping

Sugar free White Chocolate Chips or chopped chocolate. I use the white chocolate chips from Lily’s here. They also have white chocolate bar that would work too.
Crushed Peppermint Candy Canes

Tips to make Peppermint Christmas Mug Cake with Protein Powder

This flourless peppermint Christmas mug cake with protein powder really is a simple one 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 peppermint mug cake 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 protein mug cake 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 mug cake. 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.
