I make these up every few weeks and keep them in a ziploc bag in the freezer - then just pack a couple when I am going to be out and about. Have NO idea about the calorie / carb / protein counts. I use these as a bit of a treat - they satisfy the urge for a cookie / candy bar other sweet snack, while still being made of "legal" (for me, anyway) food items.
1 cup peanut butter - your choice: smooth or crunchy, natural or Skippy (Jif, whatever)
1 1/2 cups protein powder of your choice - I use Champion Double Stack Chocolate
1 cup of oats
Small handful of raisins or chopped dried apricots (optional)
1/2 cup - 1 cup of soy crisps (optional - I get these from Vitalady in chocolate flavor)
Sweetener to taste
Optional - some sf syrup in flavor of choice, such as vanilla, caramel, whatever
You could also add some chopped nuts or unsweetened dried coconut
Mix the whole gloopy mess together, add some water, a few drops at a time if it is too dry.
Roll into walnut-shaped balls. Freeze.
I think these are pretty yummy and they are a lifesaver when I am out and about, hungry, and all that I can see around me is fast food....
