Okay so I'm not reinventing the wheel here or anything, but I thought I'd share my low carb peanut butter cookie recipe. I used a few different recipes to make mine. I did this exact recipe yesterday and just warning you: it's hard to eat only one.
1 cup peanut butter (as I have learned, do not use low/no fat PB, they will not bake properly)
Sweetener equivalent to 1 cup sugar (I use Truvia)
2 teaspoons vanilla
2/3rds cup oats (or up to 1 cup, if carb count is not an issue to you)
1 teaspoon Cinnamon
1 tablespoon coarse sea salt
Chocolate chips (optional)
Mix peanut butter, sweetener, egg, vanilla, and oats in a mixing bowl with a wooden spoon. You may want to use a spatula to scrape off the dough from the sides of the bowl later on (can't let any of the dough go to waste!).
Lay a sheet of aluminum foil on a cookie pan and spray with cooking spray.
Drop rounded spoonfuls on the pan, and criss-cross flatten with a fork. I can get 20 cookies out of this amount, but I like my cookies a bit on the small side (3" diametre or so).
Sprinkle with sea salt, and bake at 350F for 10-11 minutes.
Take aluminum foil sheet off (with cookies attached) and cool on a baking rack immediately to avoid burned bottoms (unless you're like me and love burned cookies).
