Preheat the Oven – Set your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat to prevent sticking.
Cream the Butter and Sugars – In a large mixing bowl, beat butter, peanut butter, granulated sugar, and brown sugar together until the mixture is light and fluffy (about 2-3 minutes). This step is key for soft, chewy cookies!
Pro Tip: If your butter isn’t soft enough, microwave it for 10-15 seconds—but don’t let it melt completely!
Add the Wet Ingredients – Mix in the egg and vanilla extract until fully combined. The mixture should look smooth and creamy.
Combine the Dry Ingredients – In a separate bowl, whisk together flour, baking soda, and salt. Slowly add this to the wet mixture, stirring until just combined. Avoid overmixing, or your cookies may turn out dense instead of soft.
Scoop and Shape – Use a tablespoon or cookie scoop to roll the dough into balls, about 1-inch in size. Place them 2 inches apart on the prepared baking sheet.
Create the Crisscross Pattern – Lightly press a fork into the dough balls twice—once vertically and once horizontally—to flatten them slightly and create the signature peanut butter cookie design.
Pro Tip: Dip your fork in a little sugar before pressing to prevent it from sticking to the dough.
Bake – Place the cookies in the oven and bake for 9-11 minutes, or until the edges are set but the centers still look slightly soft. They will continue to firm up as they cool.
Cool and Enjoy! – Let the cookies cool on the baking sheet for 5 minutes, then transfer them to a cooling rack. Enjoy warm with a glass of milk or store them for later!
These cookies are even better the next day! Store them in an airtight container, and they’ll stay soft and chewy for up to a week.
