I wasn't going to post the recipe because it needs a few tweaks, but here's what I did:
...oh, and these weren't peanut butter balls, by the way. I was going more for a bar. Omit (or don't melt) the coconut oil, add a bit more protein powder, and you'll have the consistency to make balls. Using chunky PB instead of smooth would help, too.
1/4 cup coconut oil
1/2 cup peanut butter (I used smooth)
2 oz unsweetened baking chocolate
1 tsp vanilla extract
1 30-g scoop chocolate protein powder
1/2 cup TVP
sweetener to taste - sweetzfree (splenda) was all I had on hand.
Melt together the first three ingredients in the microwave, stirring frequently during heating until smooth. Stir in the remaining ingredients. Pour into a wax-paper-lined 8"x8" baking pan and chill until firm. Cut tic-tac-toe style into 9 pieces.
It came out a tad too chocolate/splenda bitter, and it could use a lot more TVP crispiness. Next time, I'm going to decrease the chocolate to 1.5 oz, double the TVP, and combine some stevia with the splenda.
I entered the nutrition info into fitday with the above changes and it looks like this, per piece: 199 calories, 16 g fat, 10 g protein, 7 g total carb - 3 g fiber = 4 g net carb.
This was sort of half way between candy and a protein bar. I added the coconut oil because I really wanted it to solidify in the fridge. You could make it more candy-like by eliminating the protein powder (obviously) and cutting back the coconut oil, or more protein-bar-like by increasing the protein powder. There was room to stir in more.
I'd love to compare similar recipes and results.
Do you guys and gals in the US find Bob's Red Mill to be ridiculously expensive? Here in Canada, it is, but I wonder if that's just because it's imported. For Canadians, you can get all of those BRM "low carb dry goods" w-a-y cheaper at health food stores and Bulk Barn.
