Allow me to introduce the BEST peanut butter cookies! They are soft, chewy, and packed with major peanut butter flavor. They’re also quick and easy to make – no chill time necessary!
Preheat oven to 350°F and line a baking sheet with parchment paper.
In a medium bowl, sift the flour, salt, baking soda, baking powder, and cornstarch.
In a large bowl, cream the softened butter with both sugars until light and fluffy. Mix in the peanut butter, scrape down the sides of the bowl as needed. Add eggs one at a time and mix until just incorporated after each. Add the vanilla and mix until smooth.
Add the dry ingredients to the wet ingredients in 2 batches. Mix until smooth and no more flour pockets remain.
Take 2 tablespoons of dough at a time and roll into balls with your hands. Arrange on the prepared baking sheet 2 inches apart. Use a long fork to flatten each ball into a criss-cross pattern. Sprinkle the tops with more sugar, if desired.
Bake in the preheated oven for 12 minutes. Allow the cookies to cool on the pan for at least 5 minutes before serving. Serve warm.
