Preheat your oven to 375°F (190°C) and line your baking sheets with parchment paper.

In a large mixing bowl, combine softened butter, creamy peanut butter, light brown sugar, and granulated sugar. Beat the mixture on medium speed until smooth, about 2-3 minutes.

Incorporate the egg and vanilla extract into the peanut butter mixture and beat on low speed until fully combined.

Gradually add the all-purpose flour, baking soda, and salt. Mix on low speed until just combined.

Fold in the semisweet chocolate chips with a spatula until evenly distributed.

Using a cookie scoop or tablespoon, drop rows of dough onto the baking sheets with 2 inches of space between each scoop.

Bake for 8-10 minutes for smaller cookies and 11-12 minutes for larger ones until golden around the edges.

Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack.
