Why make protein mug cake?

Looking for a healthy dessert that can be made in minutes? Look no further. This high protein mug cake is a guilt-free way to satisfy your sweet tooth. It is delicious, packed with protein, and does not require added sugar. Plus, it can be made in a single bowl in the microwave, which means easy clean-up.

This recipe makes a large serving, so feel free to share! Or you can eat it all yourself, which is what I would do. My only advice is to use a deep mug so that the cake does not overflow while cooking.

If you are sick and tired of relying on protein shakes to get the protein you need, give my protein mug cake a try. It is an easy and crave-worthy way to change up how you get your protein. It is also highly customizable, meaning you can add ingredients like chocolate chips, nuts, and toasted coconut for extra flavor.

Why drink wholesome?

This recipe was made with drink wholesome – the only protein powder made with 100% real foods. Given its simple ingredient list, it makes delicious mug cakes. Most protein powders, on the other hand, are not good for protein mug cakes because they are made with protein isolates. Isolates, which are listed on the ingredient list as “pea protein” and “whey protein” as opposed to “peas” and “whey,” are foods stripped of everything but the protein. Unlike real foods, they are missing the nutrients that make food taste good. It follows that protein isolates taste like chalk, and turn fluffy mug cakes into hockey pucks. Avoid them at all costs.

Another reason why drink wholesome is perfect for protein mug cakes is that it is sweetened with monk fruit. Monk fruit, also known as lo han guo, is a small, melon-like round fruit native to Southeast Asia. It is turned into a sweetener by removing the seeds and skin, crushing the fruit, and collecting the juice, which is then dried into a powder. Monk fruit is sweet like sugar, unlike the artificial sweeteners and stevias used to sweeten most protein powders. Artificial sweeteners and stevia have an awful bitter aftertaste because they activate bitter taste receptors in addition to sweet taste receptors. They may be sugar-free, but they will ruin your protein mug cake.

How to make protein mug cake.

Making protein cake in a mug is easy. It requires no cooking skills and or fancy equipment, and can be whipped up in no time at all. Plus, you probably already have all of the ingredients you need at home. It follows that if you are anything like me, you will be making mug cake with protein powder once a week. Depending on the type of protein powder you use, you may have to adjust ratios, but once you have found the right protein powder, this recipe is foolproof.
