Preheat oven to 350 degrees (F). Grease an 8x8 baking pan with butter or non-stick spray; set aside.
In a medium-sized saucepan combine the peanut butter and butter; heat over medium-low until the butter is completely melted; whisk well to combine; remove from heat.
Add the sugar into the saucepan and beat well until combined. Add in eggs, one at a time, beating well after each addition. Stir in the flour, baking powder, and salt, mixing just until combined.
Stir in the chocolate chunks, peanut butter chips, peanut butter cups, peanut butter candies, and peanut butter granola (if using).
Using a rubber spatula spread mixture evenly into prepared pan and bake for 25-35 minutes, or until just firm and lightly golden brown. Remove from oven and let cool completely before cutting (about 25 minutes), and then devour.
Notes
*For a prettier presentation, sprinkle some extra candy on top of the batter before baking! *Feel free to leave any ingredient out that you may not favor; these cookie bars are incredibly adaptable. *Keep an eye on the cookie bars around the 20 minute mark, you want them to be set in the center, but not firm, as they will continue to firm up once removed from the oven.
