Ingredients You’ll Need
- Peanut Butter – Choose creamy peanut butter with no added sugar. Avoid natural peanut butters with excess oil, as they can make the cookies greasy.
- Sugar Alternative – Use a granular, bake-friendly substitute that measures 1:1 like sugar.
- Egg – At room temperature and slightly whisked, for structure and binding.
👉 Expert Tip: Stir your peanut butter before adding it to the dough so it blends smoothly.
Optional Add-Ins
- Chopped peanuts (extra crunch)
- Sugar-free chocolate chips
- Raisins or dried fruit
- Crushed pretzels for a salty-sweet twist
How to Make 3-Ingredient Peanut Butter Cookies
- Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper.
- Mix ingredients – In a large bowl, cream together the peanut butter and sugar alternative until smooth and fluffy. Add the egg and mix until combined.
- Shape cookies – Scoop the dough into balls and place them 2 inches apart on the baking sheet. Flatten slightly with your hand.
- Crisscross design – Press a fork into the dough balls in a crisscross pattern to flatten further. (Tip: Spray or wet the fork to prevent sticking.)
- Bake for 7–10 minutes, or until the edges are golden.
- Cool on the baking sheet for a few minutes, then transfer to a wire rack to set.
Tips for Perfect Peanut Butter Cookies
- Don’t overbake — these cookies can dry out quickly.
- Check doneness by looking at the edges; they should be lightly golden.
- To avoid oily cookies, skip natural peanut butters with added oils.
- For crispier cookies:
- Bake a few minutes longer.
- Flatten the cookies thinner before baking.
- Let them cool fully on the baking sheet.
Storage Instructions
- Store cooled cookies in an airtight container at room temperature for up to 3 days.
