The Basic 3-Ingredient Peanut Butter Cookie Recipe

Ingredients:

1 cup creamy peanut butter
1 cup granulated sugar
1 large egg

Instructions:

Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
Mix all ingredients in a medium bowl until well combined. The dough will be thick and a bit sticky.
Scoop dough into small 1-inch balls using a spoon or cookie scoop.
Roll balls gently in your hands and place them on the prepared baking sheet about 2 inches apart.
Flatten each ball with a fork, making a crisscross pattern on top.
Bake for 10–12 minutes, or until the edges are lightly browned.
Cool on the sheet for 5 minutes, then transfer to a wire rack to cool completely.

Best Type of Peanut Butter for This Recipe

While you can technically use any kind of peanut butter, for the best 3-ingredient peanut butter cookies, stick to the following tips:

Avoid Low-Fat or No-Sugar Peanut Butter: These can alter the taste and consistency of the cookies.

1/2 teaspoon vanilla extract
Pinch of sea salt on top
Mini chocolate chips or chopped peanuts

1. Can I use almond butter instead of peanut butter?

Yes, almond butter or even cashew butter can be used. The texture may vary slightly, but the result is still a delicious, simple cookie.

Tips for Perfect Peanut Butter Cookies Every Time

✅ Don’t Overmix

Too much mixing can make the dough oily or stiff. Just stir until the ingredients are well combined.

✅ Don’t Overbake

Cookies continue to cook after being removed from the oven. If you bake too long, they’ll turn dry or crumbly. Look for light browning at the edges.

✅ Use a Fork for the Classic Crisscross Pattern

This not only flattens the cookies for even baking but also gives them that iconic peanut butter cookie look.

Make It Healthier: Clean-Eating Options

You can easily make these cookies healthier without sacrificing flavor:

Use natural peanut butter with no added sugar or hydrogenated oils.
Replace sugar with organic coconut sugar or a sugar-free alternative.
Add chia seeds or flaxseeds to boost fiber and omega-3s.
Mix in a bit of oat flour or almond flour if you want a slightly cakier texture.
