Ingredients for 3-Ingredient Peanut Butter Cookies (No Flour)

1. Peanut Butter

Use creamy peanut butter for best results. Brands like Skippy or Jif work perfectly. Avoid natural peanut butter that separates easily unless you mix it extremely well; otherwise, the dough may become crumbly.

2. Sugar

You can use granulated sugar for the traditional version. If you prefer a less-sweet cookie, reduce the sugar by 2–3 tablespoons. For a lower-carb version, use a sugar substitute like monk fruit or stevia blends.

3. Egg

One large egg binds the dough and gives the cookies a soft, chewy texture.

These simple ingredients combine to create surprisingly flavorful and satisfying cookies with an iconic peanut butter taste.

Step-by-Step Instructions for 3-Ingredient Peanut Butter Cookies (No Flour)

Step 1: Preheat Your Oven

Set your oven to 350°F (175°C). Line a baking sheet with parchment paper for easy cleanup.

Step 2: Mix the Ingredients

 

In a medium-size mixing bowl, combine:

• 1 cup creamy peanut butter

• 1 cup sugar

• 1 large egg

Mix until the dough becomes thick, sticky, and smooth.

Step 3: Scoop and Shape

Using a small cookie scoop or spoon, form 1-inch balls and place them on your baking sheet. Leave space between cookies—they will spread slightly.

Step 4: Make the Signature Fork Pattern

Press each dough ball lightly with a fork in a crisscross pattern. This classic peanut butter cookie look also helps the cookies bake evenly.

Step 5: Bake

Bake for 8–10 minutes until the edges are firm. The centers may look soft—this is normal. They will firm up as they cool.

Step 6: Cool

Let the cookies cool on the tray for 5 minutes before transferring to a wire rack.

Step 7: Now transferring to a wire rack.

Expert Tips for the Best Peanut Butter Cookies

• Don’t overbake. These cookies dry out quickly. Remove when edges are lightly golden.

• Use creamy peanut butter. Crunchy or natural peanut butter can make dough crumbly.

• Let cookies cool fully. They set and become chewy as they cool.

• Use parchment paper. Prevents sticking and keeps cookies soft.

• Chill dough for thicker cookies. Refrigerating the dough for 20 minutes prevents spreading.

Variations You’ll Love
