Preheat your oven to 350°F (175°C) and prepare a baking sheet with parchment paper.

In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until fluffy and light, about 2-3 minutes.

Add in the eggs one at a time, mixing well after each addition, then blend in the vanilla extract until everything is perfectly combined.

Gradually sift in the flour, cocoa powder, baking soda, and salt. Stir gently until just combined to keep cookies soft and chewy.

Gently fold in the chocolate chips, ensuring they are evenly distributed throughout the dough.

Use a cookie scoop to dollop the dough onto your prepared baking sheet, ensuring room to spread. Bake for 10-12 minutes until the edges are set and centers are soft.

For the frosting, mix the creamy peanut butter with powdered sugar until smooth and spreadable. Frost your cooled cookies generously.
