Peanut Butter Oreo Cheesecake Bars

Preheat oven to 350° F. Lightly grease an 8” x 8” square pan with cooking spray. Line with parchment paper to create a sling, with an overhang on all four sides.
Oreo Crust: In a food processor, add the oreos and pulse to fine crumbs. Combine the crumbs with the melted butter in a bowl. Press the mixture evenly into the bottom of the prepared pan, firmly packing it down. Bake for 8 minutes. Set the crust aside and leave the oven on.
Peanut Butter Cheesecake Filling: Using a handheld mixer or a stand mixer fitted with a paddle attachment, combine the cream cheese and sugar until smooth and no lumps remain.
Add the peanut butter, milk, flour, and vanilla extract, mixing just until combined. Fold in the chopped oreos.
Pour the cheesecake filling onto the baked oreo crust. Bake for 45-50 minutes until the top of the cheesecake is lightly brown and the edges slightly start to crack.
Leave the cheesecake at room temperature until cool enough to handle then refrigerate until it is completely cool and chilled before cutting.
Once cooled, remove the cheesecake from the pan and cut it into pieces.
Ganache Topping: Combine the chocolate and heavy cream in a microwave-safe dish and heat in 20-second increments, stirring in between until melted.
Drizzle the warm ganache on the cheesecake bars and top with more crushed oreos, if desired, and enjoy!
