Start by preheating your oven to 350°F (175°C)
In a medium bowl, combine your dry ingredients—this includes flour, and a pinch of salt. Set them aside for now.
1 1/4 cup Flour, 1/2 tsp. Salt
Next, grab a large mixing bowl and cream together your softened butter and granulated sugar using a hand mixer or stand mixer to beat them together until the mixture is smooth and fluffy, which should take about 2-3 minutes.
1/2 cup Butter, 1 cup White Sugar
Once that’s done, add in the egg and vanilla extract and peanut butter, and continue mixing until everything is fully combined.
1 large Egg, 2 tsp. Vanilla Extract, 1 cup Creamy Peanut Butter
Now, slowly add your dry ingredients to the wet ingredients, stirring just until incorporated. The dough will be thick but smooth.
1 1/4 cup Flour, 1/2 tsp. Salt
Using a 2-tablespoon cookie scoop, portion out the dough onto a baking sheet lined with parchment paper or a silicone mat, spacing the cookies about 2 inches apart.
Once all the dough is scooped, take a fork and gently press down on each cookie, creating the classic peanut butter cookie crisscross pattern.
Place the cookie sheet in the oven and bake for 10 to 13 minutes. Keep an eye on them—they’re ready when the edges are slightly browned, and the tops have set.After baking, remove the cookies from the oven and let them cool on the tray for a few minutes before transferring them to a wire rack to cool completely.
