These puffy peanut butter cookies with chocolate chips are my most favorite peanut butter chocolate chip cookie ever! They are soft but also a little chewy and the combination is just to die for! Comes together super easily too.
Preheat oven to 325 degrees F. Add butter and peanut butter to a microwave safe bowl, and heat in 30 second increments until melted. Let cool completely.
Mix the flour and baking soda in a bowl and set aside. In another bowl, mix the cooled butter/peanut butter and sugars until they are combined. Add the egg, egg yolk, and vanilla and stir until mixed. Gradually add flour and mix until a dough forms – it will look crumbly at first, but it will come together. I even used my hands to bring it all together. If necessary, add 1-2 teaspoons of milk, but I did not need this. Fold in chocolate chips.
Shape the dough into a ball the size of a golfball. Place on a baking sheet two inches apart and bake for 10-12 minutes or until the edges are slightly brown. The centers should be soft and puffy. Do not over bake. Let cool completely then dig in!
