  • White chocolate chips
  • Homemade berry jam or preserves
  • Raspberries, blueberries, blackberries, strawberries, goji berries
  • Bananas
  • Mango chunks
  • Pineapple bits 
  • Pomegranate seeds (Pairs great with dark chocolate!)
  • Nuts, such as pistachios, almonds, peanuts, walnuts, pecans, and cashews
  • Nut butter, such as peanut butter, almond butter, cashew butter

  • Keto vanilla ice cream (Great low-calorie alternative!)
  • Shredded toasted coconut flakes
  • Cinnamon or Cocoa powder
  • Chia pudding 
  • Pretzels 

Suggestions and Tips

Ensure your mug is big enough to prevent batter overflow while the cake cooks. If using vegan protein powder, add enough almond milk to create a pudding-like consistency in the batter. If you prefer a larger dish to cook the dessert in, we suggest you use a baking dish for brownies. 

If you plan on using vegan protein powder, only use a small amount of almond milk or your preferred non-dairy beverage. If you want to bake the protein cake in the oven, make sure to add half a teaspoon of baking powder. To create a thinner consistency of the batter, you may add half a tablespoon of water, milk, or any other plant-based milk. 

Sit back and relax from that post-workout with this easy-to-make dessert. Don't wait. Dig in!

Suggested Protein Powders for Baking:

Whey Protein:

Whey is fast-digesting, which is why it is an excellent post-workout drink; whey protein is the byproduct of milk when cheese or yogurt is formed.

Whey Protein Concentrate: 

This is the most often-seen form of whey protein. A concentrate indicates that 80 percent of the product is protein. 

Whey Protein Isolate: 

Isolate is a "stronger" protein powder that must include at least 90% protein. It will be practically carb-fat-free but may consist of minor quantities.

Casein Protein:

Casein is the other byproduct of milk, in contrast to whey, and is the primary protein in milk. 

Egg Protein

Egg protein is a common alternative for anybody who can't tolerate dairy very well. Egg protein consists of egg whites in powdered form.

Plant-Based Protein

There are a plethora of plant-based protein powders on the market. Pea protein and brown rice protein are the two most popular forms.
