Method
- Preheat the oven to 350 F. In a medium bowl, whisk together flour, salt, baking soda, and cream of tartar. In a large bowl, combine butter, peanut butter, and both sugars until fluffy.
- Add in egg and vanilla extract, mix until smooth. Add in the flour mixture, and mix until it is fully combined. Combine sugar and cinnamon in a shallow dish.
- Roll the cookie dough into balls, and roll each one into the cinnamon and sugar mixture. Place the cookies onto a large ungreased baking sheet at least 2-inches apart. Bake for 10-12 minutes.
