Step 1: Preheat the Oven: Preheat the oven to 375F (190C). Ensure the oven rack is positioned in the center for even baking.
Step 2: Cream Together Butter and Sugars: In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until the mixture is light and fluffy. This process incorporates air, which contributes to the cookie's texture.
Step 3: Add Vanilla, Eggs, and Peanut Butter: Beat in the vanilla extract, followed by the eggs, one at a time, mixing well after each addition. Gradually add in the peanut butter, ensuring it is fully incorporated into the mixture.
Step 4: Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. This ensures that the baking soda is evenly distributed throughout the flour.
Step 5: Gradually Add Dry Ingredients to Wet Ingredients: Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix, as this can result in tough cookies.
Step 6: Drop by Rounded Tablespoons onto Baking Sheets: Drop rounded tablespoons of dough onto ungreased baking sheets, leaving about 2 inches between each cookie to allow for spreading.
Step 7: Flatten Cookies with a Fork: Use a fork to flatten the cookies, pressing down in a crisscross pattern. This not only creates a visually appealing design but also helps the cookies bake evenly.
Step 8: Bake: Bake for 10-12 minutes, or until the edges are golden brown and the centers are set.
Step 9: Cool on Baking Sheets: Remove the baking sheets from the oven and let the cookies cool on the sheets for a few minutes before transferring them to a wire rack to cool completely. This allows the cookies to firm up slightly, preventing them from breaking.
Tip: For a richer flavor, use natural peanut butter. If the dough seems too soft, chill it for 30 minutes before baking.
