Line a large sheet pan with a silicone liner or parchment paper and set aside.
In a microwave-safe bowl, heat the butter until it’s melted. Set aside to cool back to room temperature.
In a large bowl, combine cooled butter, brown sugar, and granulated sugar. Mix with a large whisk until smooth and creamy, about 1 minute.
Add peanut butter and vanilla extract. Mix until combined. Add in 1 egg and mix until incorporated, then add the second egg and mix again.
Add baking soda and salt and mix until just incorporated.
Fold in flour until just incorporated, then fold in the chocolate chips.
Cover dough and chill for 30 minutes to 1 hour. Preheat oven to 325°F.
Scoop dough and roll into balls (2 tablespoons each). Place on the lined sheet pan, leaving space between each.
Bake for 8 to 14 minutes. Let cool on the sheet pan for 5 minutes before transferring to a cooling rack.
