  • 1 1/2 serving (37g) Swerve Chocolate Cake Mix
  • 2/3 scoop (21g) PEScience Vanilla Protein Powder or your choice of protein powder
  • 1 Tbsp (14g) Light Butter I used Land O'Lakes
  • 1/4 C (60mL) Fairlife Whole Milk or your choice of liquid


  1. Mix everything together in a small bowl or mug and microwave for 75-90 seconds or until the center is mostly cooked. (I like to leave the center a bit gooey.) 

  2. Top with fat free whipped cream, a scoop of lighter ice cream, or something like my chocolate frosting

Recipe Notes

  • Feel free to swap butter and milk for something like coconut oil and almond milk for dairy free.
  • You could also use a lower calorie milk option to reduce the fat and calorie content even further.
