With soft, chewy centers and crisp edges, these Chewiest Peanut Butter Cookies are a must-try. They come together quickly and are perfect for snacking, gifting, or enjoying with a glass of milk.
In the bowl of a stand mixer fitted with the paddle attachment, combine the sugars, peanut butter, butter, and vanilla extract. Beat on high for 2 minutes until light and fluffy. Add the egg and yolk, mixing until combined.
In a separate mixing bowl, whisk together the flour, baking soda, cornstarch, and salt.
With mixing speed on low, gradually add the dry ingredients to the wet mixture, mixing just until combined. Cover the bowl with plastic wrap and refrigerate for 15 minutes.
Meanwhile, preheat the oven to 350 degrees Fahrenheit (175 degrees Celsius). Line two cookie sheets with parchment paper or silicone baking mats; set aside.
Using a standard-size cookie scoop, create equal-sized balls of dough. Roll in the sugar and place onto the prepared cookie sheets. Bake the cookie dough balls for 10-12 minutes; do not overbake. The cookies will appear underdone, but they will set as they cool. Remove from the oven and allow to cool on the sheets for 3 minutes before carefully transferring them to a wire rack to cool completely.
Notes
-Rolling the cookies in sugar is optional.-Since these aren’t as thick as traditional crisscross cookies, I wouldn’t recommend adding chips unless they’re miniature chocolate chips.STORE your Soft Peanut Butter Cookies in an airtight container on the counter at room temperature. They will remain soft and flavorful for up to a week. For extended storage, place the cookies in a single layer in a freezer-safe bag or container and FREEZE for up to 3 months.When you're ready to enjoy them, allow the cookies to thaw at room temperature. If you prefer warm cookies, REHEAT them in a preheated oven at 300 degrees Fahrenheit (150 degrees Celsius) for about 5 minutes or microwave them for a few seconds until warm.
