Place the peanut butter, butter and sugars together in a stand mixer fitted with a paddle attachment. Beat about 2-3 minutes until light and fluffy.
Add eggs one at a time, mix until smooth on low speed. Beat in vanilla.
Slowly mix in dry ingredients, being careful not to over mix. I usually stop when I still have some flour remnants around the bowl.
Using a large cookie scoop, (I use a 3 TBSP) scoop dough into balls and place on a large cookie sheet. Chill dough for 3 or more hours if you have the time. They will taste better and spread less this way.
Preheat oven to 375 F. Line two cookie sheets with parchement paper.
Roll cookie dough balls in granulated sugar.
Place 6-8 balls per sheet. Bake for 10-12 minutes, or until edges are slightly golden brown. Let cool on the cookie sheet for 5-10 minutes to help the center finish setting.
Notes
These cookies can be stored in an airtight container for 2-3 days, or months in the freezer.I like to sprinkle extra sugar on top of the cookies after they bake for an extra pretty look. And if you know me, sometimes a little salt too!I have given both cups and grams as measurements. Grams will be more precise, especially when measuring flour. If you don’t have a kitchen scale, no problem! Just lightly spoon flour into your measuring cup to insure its not packed in there. Light and fluffy is the key.
