Step 1: Preheat the oven to 350ºF.
Step 2: Spray a 9x13-inch baking dish with nonstick spray.
Step 3: Add the butter and chopped chocolate to a microwave-safe bowl and microwave until melted, 30 to 60 seconds.
Step 4: Once the chocolate is semi-melted, stir constantly to melt the rest. Set aside and allow the mixture to cool for 5 minutes.
Step 5: In a small bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt.
Step 6: In a large bowl, whisk together the melted butter-chocolate mixture and granulated sugar. Whisk in the eggs, egg yolk, and vanilla extract, stirring until a smooth batter forms. With a large spoon, mix in the dry ingredients until combined.
Step 7: Stir in the chocolate chips. Add the batter to the baking dish.
Step 8: Bake until the brownies are set and no longer jiggly in the middle, 25 to 30 minutes. Remove from the oven and let them cool for 30 minutes.
Step 9: Stir together the melted peanut butter, powdered sugar, and coconut oil until smooth. The peanut butter will be warm and melt the coconut oil, so stir until melted.
Step 10: Pour the filling over the brownies, using a spatula to spread it around the top.
Step 11: Let cool completely and firm up, 20 minutes.
Step 12: Add the chocolate to a large bowl.
Step 13: Heat the cream in a small saucepan over medium heat just until it bubbles around the edges. Remove the cream from the heat and pour it over the chocolate. Let the mixture stand for 30 seconds, then stir continuously until the chocolate melts and a smooth ganache comes together, 1 to 2 minutes.
Step 14: Pour it all over the top of the brownies, then cover it with the chopped peanut butter cups. Let the brownies sit for 30 minutes before cutting.
