I feel like I have a number of peanut butter cookies on this blog already, but this one is too good to not pass along. This cookie is slightly cakey and very peanut buttery, which is what I look for in the perfect peanut butter cookie. This recipe is adapted slightly from My Kitchen Cafe.
1 cup butter, softened to room temperature
2 cups smooth or chunky peanut butter
1 1/2 cups firmly packed light brown sugar
1 cup granulated sugar
2 large eggs
1 1/2 tablespoons milk
1 1/2 teaspoons pure vanilla extract
2 1/2 cups all-purpose flour
1 1/2 teaspoons baking soda
1 teaspoon baking powder
1/2 teaspoon salt
2 cups chocolate chips (or a combination of peanut butter and chocolate chips)
Preheat oven to 350 degrees. In a large bowl combine the butter and peanut butter and beat the mixture until it is light and fluffy (you can do this with a hand mixer or with an electric mixer). Add the sugars and mix until well combined. Add the eggs and mix for 1-2 minutes. Blend in the milk and vanilla. Add the dry ingredients and mix just briefly. While there are still large spots of flour, add the chocolate chips (or peanut butter chips or both) and mix until the flour is completely mixed in and the mixture is well combined. Let the cookie dough sit for 15 minutes before scooping onto the baking sheets. The dough will firm up as it sits.
When ready to bake, scoop tablespoon-sized balls of dough onto silpat or parchment-lined baking sheets, leaving about 1 to 2 inches in between the cookies to allow for spreading as they bake. Bake for 10-11 minutes, taking care not to overbake. Leave the cookies on the baking sheet for 2-3 minutes after baking before removing them to a cooling rack. This will help them set up and be firm enough to transfer without having them overbake in the oven. The cookies may look slightly underbaked but they will firm up as they cool. Resist the urge to eat them warm as they taste much better cooled.
Makes about 4-5 dozen cookies. Baked cookies can be frozen, and they taste great out of the freezer, especially if they are left to sit at room temperature for a few minutes.
