These peanut butter cookies are truly chewy. They have a slight crisp around the edges with a soft and chewy middle. If you're looking for a chewy peanut butter cookie, this is your recipe.
In a medium-sized bowl, whisk the flour, baking soda, and salt.
1 ¼ cups all purpose flour, ½ teaspoon baking soda, ½ teaspoon salt
In a large mixing bowl, cream the brown sugar and butter using electric beaters for 1 minute, until creamy. Add the peanut butter, egg, egg yolk, and vanilla and beat until just combined.
1 cup brown sugar, ½ cup unsalted butter, ½ cup unsalted peanut butter, 1 large egg, 1 egg yolk, 1 teaspoon vanilla
Add the dry ingredients and beat just until there are no streaks of flour - do not overmix the dough.
Cover the dough with a piece of parchment or wax paper pressed into the top then put the bowl into your fridge for 2 hours. Do not skip this step - see notes.
Preheat your oven to 350 degrees Fahrenheit. Use a large cookie or ice cream scoop (¼ cup) to portion the dough into five large balls and space them evenly on a cookie sheet. Do not roll them or press them down.
Bake the cookies for 15-16 minutes, then remove them from the oven and let them cool for 10 minutes on the baking sheet before moving them to a cooling rack. Repeat with the remaining dough, adding it to a cool baking sheet.
Notes
Chilling the dough: This is an important step—do not skip it. If the dough is baked right away, it will be very soft, difficult to work with, and spread too much in the oven. For the best cookies, let the dough rest for at least 2 hours. Peanut butter: Processed peanut butter is one of the few foods I can't stand, so I don't keep it in my kitchen. This recipe was tested with a few different brands of smooth, natural peanut butter. It turned out well with all the brands, but Earth's Choice peanut butter made the chewiest peanut butter cookies. Size matters! I tested various-sized cookies, and ¼ cup portions made chewy cookies. Smaller ones taste great, but they aren't as chewy.
