Ingredients

- Powdered sugar: sweetens without graininess allowing for that silky mouthfeel

- Lemon juice: brightens the filling with a subtle tang that balances the sweetness
- Cheesecake flavored instant pudding mix: stabilizes the filling without baking a genius shortcut
- Half and half: creates the perfect creamy consistency without being too heavy
- Oatmeal cream pies: form both the crust and decoration choose fresh soft cookies for best results

Step-by-Step Instructions
- Prepare the Crust:
- Line your springform pan with parchment paper then create a foundation layer with whole oatmeal cream pies placed side by side. Add a second layer of cookies then stand halved cookies around the inner edge of the pan creating a decorative border. The cookies will soften as they absorb moisture from the filling creating a cake like crust.
- Mix the Cream Cheese Base:
- Beat the softened cream cheese until completely smooth and free of lumps this step is crucial for a velvety filling. Add vanilla and lemon juice then mix until incorporated. The lemon juice brightens the flavor while helping stabilize the structure.
- Prepare the Pudding Mixture:
- In a separate bowl whisk half of the cheesecake pudding mix with half a cup of half and half adding the extra two tablespoons gradually until smooth. This creates a thickening agent that helps the cheesecake set properly without baking. Ensure no graininess remains before proceeding.
- Combine the Filling:
- Add the pudding mixture to the cream cheese and blend until perfectly incorporated. Gradually add powdered sugar mixing thoroughly after each addition until silky smooth. The slow addition prevents lumps and ensures even sweetness throughout.
- Assemble and Chill:
- Pour the creamy filling over the oatmeal cream pie crust smoothing the top with a spatula. Freeze for two hours to set the structure then transfer to the refrigerator covered with waxed paper and foil for at least 12 hours. This two stage chilling process ensures the perfect texture.
- Decorate and Serve:
- Pipe generous swirls of buttercream frosting around the perimeter using a decorative tip. Crumble remaining oatmeal cream pies in the center and place cookie pieces artfully between frosting swirls. The combination of textures and visual appeal makes each slice a work of art.

The cheesecake flavored pudding mix is truly the secret weapon in this recipe. I discovered this trick when I was developing a summer cheesecake menu for a family reunion in July. Everyone was amazed that such a perfectly set cheesecake could be created without ever turning on the oven. Now I keep packets of this pudding mix in my pantry year round for dessert emergencies.
Storage and Make Ahead Tips
This cheesecake actually benefits from being made at least a day ahead allowing flavors to meld and textures to soften perfectly. Store leftovers in the refrigerator for up to five days keeping the springform ring on until ready to serve additional slices. For longer storage individual slices can be wrapped tightly and frozen for up to two months. Let frozen slices thaw overnight in the refrigerator for best texture.
Perfect Substitutions
While the recipe specifies store bought oatmeal cream pies homemade cookies work beautifully if you have a favorite recipe. The cheesecake pudding mix can be replaced with vanilla pudding mix plus a teaspoon of lemon zest for a similar effect. For a lighter version substitute Neufchâtel cheese for regular cream cheese and light whipped topping for the buttercream frosting decorations.
Serving Suggestions
This cheesecake shines on its own but can be elevated with accompaniments. Serve slices with a small scoop of cinnamon ice cream or a drizzle of caramel sauce for an extra special touch. For a beautiful presentation add fresh berries around the base of the cheesecake when serving. Cut slices with a knife dipped in hot water and wiped clean between cuts for the cleanest presentation.
