Preheat and Prep: Preheat oven to 350°F (175°C). Grease or line a 10-inch skillet or baking pan with parchment paper.
Mix Wet Ingredients: In a large bowl, cream together butter, brown sugar, and granulated sugar until light and fluffy. Add eggs and vanilla extract, mixing until smooth.
Add Dry Ingredients: In a separate bowl, whisk together flour, baking soda, and salt. Gradually add to the wet mixture, mixing until just combined.
Fold in Add-ins: Gently fold in chocolate chips, crushed Oreos, and dollops of peanut butter.
Bake the Pizzookie: Spread dough evenly in the prepared pan. Bake 18–22 minutes until edges are golden but the center remains soft and gooey.
Finish and Serve: Let cool slightly, then drizzle with extra melted peanut butter or chocolate if desired. Serve warm with vanilla ice cream for the ultimate dessert experience.
