Cream butter and sugars. Add eggs, vanilla, and peanut butter. Beat until smooth.
Add dry ingredients and mix until soft dough forms.Tip: Chill the dough for 1-2 hours before baking. It's easier to scoop, and the cookies bake up sturdier.
Preheat the oven to 350 degrees. Use a 2 Tbsp. sized cookie scoop to scoop dough onto parchment-lined baking sheets.
Bake cookies for 12-14 minutes. Cool completely on baking sheets.
