3-Ingredient Peanut Butter Cookies Recipe
Introduction
These 3-Ingredient Peanut Butter Cookies are delightfully simple and quick to make, perfect for satisfying your sweet tooth with minimal effort. With just peanut butter, sugar, and an egg, you can enjoy soft and chewy treats that highlight the rich flavor of peanut butter.

Ingredients
- 1 cup smooth peanut butter (well-stirred if using natural peanut butter)
- 3/4 cup granulated sugar
- 1 large egg
Instructions
- Step 1: Arrange two oven racks to divide the oven into thirds and preheat the oven to 350℉. Line two rimmed baking sheets with parchment paper or silicone baking mats.
- Step 2: In a large bowl, combine the peanut butter, sugar, and egg. Mix thoroughly with a flexible spatula until the dough is well combined.
- Step 3: Scoop the dough into 24 level 1-tablespoon portions and roll each into a ball. Place the balls on the prepared baking sheets, spacing them at least 2 inches apart, with 12 dough balls per sheet.
- Step 4: Flatten each dough ball with a fork to about 2 inches wide and 1/4 inch thick, creating a crosshatch pattern on top.
- Step 5: Bake the cookies for 5 minutes. Then, rotate the baking sheets between the oven racks and turn them front to back.
- Step 6: Continue baking for 5 to 7 more minutes until the centers are set, the cookies are lightly puffed, and the edges are firm.
- Step 7: Let the cookies cool completely on the baking sheets, about 30 minutes. They will firm up as they cool.
Tips & Variations
- Use natural peanut butter for a more intense peanut flavor, but make sure to stir it well before measuring.
- Add a pinch of salt to balance the sweetness, especially if using unsalted peanut butter.
- For a chocolate twist, dip half of each cooled cookie in melted dark chocolate and let it set.
- If you prefer crunchy cookies, fold in some chopped peanuts before baking.
Storage
Store the cookies in an airtight container at room temperature for up to one week. To keep them soft, add a slice of bread to the container. These cookies can also be frozen for up to 3 months; thaw at room temperature before serving. To refresh slightly hardened cookies, warm them in the microwave for 10-15 seconds.
