Preheat the Oven: Preheat your oven to 350°F (175°C).
Mix the Wet Ingredients: In a large mixing bowl, cream together the softened butter, peanut butter, granulated sugar, and brown sugar until smooth and creamy.
Add the Eggs: Mix in the eggs and vanilla extract until well combined.
Combine the Dry Ingredients: In a separate small bowl, stir together the flour, baking soda, and salt. Gradually add the flour mixture to the wet ingredients, mixing until just combined.
Form the Cookies: Scoop slightly rounded tablespoons of dough onto a baking sheet, leaving about two inches between each cookie. Optionally, roll the dough balls in additional sugar for extra sweetness, then roll them between your hands until smooth.
Bake the Cookies: Bake the cookies for 7-9 minutes. They should look puffy and soft but set in the center.
Create the Paw Print: Immediately after removing the cookies from the oven, press 1 melting chocolate disk into the lower center of each cookie. Add 3-4 chocolate chips around the disk to form a paw print design.
Cool: Transfer the cookies to a wire rack to cool completely. Allow the chocolate to set before stacking for storage.
