Prepare the Pudding – In a medium bowl, whisk together banana pudding mix and whole milk until smooth. Let it sit for 5 minutes to thicken.
Make the Whipped Cream – In a separate bowl, beat heavy whipping cream with a hand mixer until firm peaks form. Transfer to a piping bag.
Assemble the Mini Pies – Spoon banana pudding into the mini pie crusts. Layer banana slices on top, then sprinkle with crushed graham crackers.
Add Whipped Cream – Pipe whipped cream onto each mini pie and garnish with extra graham cracker crumbs.
Chill and Serve – Refrigerate for at least 30 minutes before serving. Enjoy!
