Low-carb peanut butter cookies
Instead of using granulated sugar, you can use your favorite powdered sugar substitute to make these cookies low-carb! There are still some carbs in peanut butter though, so do the math if you're counting carbs.
Ready to start baking?
- ½ - 1 cup granulated sugar (You can use ½ cup for less sweet cookies, or up to 1 cup for sweeter cookies. Keep in mind that using half the sugar does not mean the cookie will be half as sweet, because you'll end up with a bit fewer cookies when decreasing the sugar. Notice how I list the sugar first because you can use the same measuring up if you measure out the sugar first.)
- 1 cup creamy peanut butter (Pro tip: spray the measuring cup with cooking spray or oil so the peanut butter doesn't stick to it and you get an accurate measurement. Use a spatula to get every bit of peanut butter out.)
- 1 egg

Preheat oven to 350F. Line a large baking sheet with parchment paper or a silicone baking sheet.
In a large bowl, mix together the sugar, peanut butter, and egg until smooth using an electric mixer. If you don't want to use an electric mixer, use a fork to break apart the egg and mash everything together so that the egg doesn't splash out, then continue stirring until smooth.
Scoop a spoonful of the dough and roll into a 1 inch ball. Place the dough balls onto the prepared baking sheet a couple of inches apart. Use your hand or the back of a fork to flatten the balls and then form a crisscross pattern on top with a fork.
Bake for 8-10 minutes, or until the middle is almost just set. Allow to cool for a few minutes before enjoying!

Tips and tricks for perfect peanut butter cookies
- Don't make large balls of cookie dough. Scoop out just a little dough to make 1 inch balls. 1 inch is pretty small!
- Do not overbake the cookies! Bake them just until the middle starts to set, then remove them from the oven. They will continue cooking for a few minutes as they are cooling.
- Do NOT try to remove the cookies from the pan while they're still very warm, they will fall apart. Have some patience and wait until they cool.
