Nutty, salty, and sweet - peanut butter just brings so much good flavor to these cookies. To avoid a sticky mess, I like to spray my measuring cup with non-stick cooking spray before putting the peanut butter in it. This way, the peanut butter will slide right out when it's time to add it to the mixing bowl. Or, if you see yourself making these soft peanut butter cookies often (and trust me, you will!), I recommend measuring out your peanut butter and then weighing it. By doing this, you will know exactly how much peanut butter you need to weigh out each time you make these festive favorites. Just be sure to use the same brand of peanut butter each time to ensure the same results when weighing!
