Begin by crushing the Reese's Puffs cereal in a food processor until they resemble fine crumbs. Transfer the crumbs to a mixing bowl and add a pinch of salt and the melted butter. Stir until the mixture resembles wet sand.
Evenly distribute the crust mixture into the bottoms of your mini cheesecake tins or muffin pan. Press down firmly to create a solid base. Place the crusts in the refrigerator to set while you prepare the filling.
In a large mixing bowl, beat the softened cream cheese with a whisk until smooth and creamy. Add the seeds from the vanilla bean pod or the vanilla extract, and mix until fully incorporated.
Sprinkle the vanilla instant pudding mix over the cream cheese and slowly pour in the cold milk. Whisk until the mixture thickens and becomes smooth and creamy.
Gently fold in the melted peanut butter into the cheesecake filling until fully combined.
Remove the crusts from the refrigerator and fill each one with the cheesecake mixture, smoothing the tops with a spatula. Sprinkle mini chocolate chips on top for an extra touch of sweetness.
Place the filled mini cheesecakes back in the refrigerator and let them chill for at least 4 hours, or overnight for best results. This step is crucial for the cheesecakes to firm up.
Once set, carefully remove the cheesecakes from the tins. Serve chilled and enjoy the delightful combination of chocolate and peanut butter in every bite!
