There is also a video of How to Make Peanut Butter Protein Balls.
- 1 cup sugar-free peanut butter
- 4 scoops (or 1 and 1/3 cups) whey protein powder -- most are low in carbs, but check -- any flavor
- 1 teaspoon vanilla extract
- Artificial sweetener to taste, about 1-1½ cup sugar equivalent
For sweetener, I use the most concentrated liquid sucralose (Splenda). In the past, I made the mistake of trying to add too much liquid in the form of Da Vinci's syrups for flavoring. To my dismay, it is possible to turn the whole thing into a ropey, gluey mess. I never figured out what the chemical reaction was, but it happened to me more than once. On the other hand, protein powders are fine added to shakes, so it couldn't have been just the liquid. It must have been the exact combination of fat, protein and liquid. If any food chemists have an idea about what might have happened, let me know!
I think powdered erythritol would work as a sweetener with the chocolate flavor.
Makes approximately 16 balls about one inch in diameter.
Nutritional Information: Assuming zero-carb sweetener, each ball has 3 grams effective carbohydrate plus 1 gram fiber, 9 grams protein, and 118 calories.
