Let’s Make it Together
Create the Crust: Preheat your oven to 350°F (175°C). In a mixing bowl, crush Oreo cookies until they resemble fine crumbs and combine them with melted butter.
Prepare the Baking Dish: Line an 8×8-inch baking dish with parchment paper, allowing some overhang for easy removal later. Firmly press the cookie mixture into the bottom of the dish.
Mix the Filling: In another bowl, blend creamy peanut butter, powdered sugar, and vanilla extract until smooth and creamy. This should create a luscious filling that begs to be spread.
Add the Filling Layer: Spread the peanut butter mixture evenly over your prepared crust using a spatula. Take your time to make it look pretty because we eat with our eyes first!
Add Chocolate Chips (if using): Sprinkle chocolate chips generously on top of the filling layer. Push them gently into the surface so they melt slightly while baking.
Bake and Cool: Place in the oven for about 15-20 minutes until set but still soft in center. Allow them to cool completely before slicing into bars; patience is key here!
