Ingredients

• 1 cup creamy peanut butter
• 1/2 cup unsalted butter, softened
• 1 cup brown sugar, packed
• 1/2 cup granulated sugar
• 2 large eggs
• 1 teaspoon vanilla extract
• 1 1/2 cups all-purpose flour
• 1 teaspoon baking soda
• 1/2 teaspoon salt
• 2 cups old-fashioned oats
• 1/2 cup chopped peanuts (optional)

Step-by-Step Instructions

Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper. In a large mixing bowl, cream together the peanut butter, softened butter, brown sugar, and granulated sugar until light and fluffy. This should take about 2-3 minutes with an electric mixer.

Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract. In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, mixing until just combined.

Fold in the oats and chopped peanuts if using. The dough will be thick and hearty. Using a cookie scoop or tablespoon, drop rounded balls of dough onto the prepared baking sheets, spacing them about 2 inches apart. Flatten each ball slightly with your palm or the bottom of a glass.

Bake for 10-12 minutes, or until the edges are golden brown but the centers still look slightly soft. The cookies will continue to set as they cool. For quick baking sessions, you can make smaller batches and enjoy fresh cookies in under 20 minutes.

Remove from oven and let cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely. This resting period helps the cookies achieve that perfect chewy texture.

Expert Tips for Perfect Cookies

For the best results, use room temperature ingredients. Cold butter and eggs can affect the texture of your cookies. If you prefer a crunchier cookie, bake for an additional 1-2 minutes. For extra chewy cookies, slightly underbake them and let them cool completely on the baking sheet.

Don’t overmix the dough once you add the flour. Overmixing can lead to tough cookies. The dough can be refrigerated for up to 24 hours if you want to bake in batches. Chilled dough often results in thicker, chewier cookies.
