Ingredients
- Oatmeal Cookie Base:
- 1 cup old-fashioned rolled oats
- 3/4 cup all-purpose flour
- 1/2 teaspoon baking soda
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon salt
- 1/2 cup (1 stick) unsalted butter, softened
- 1/2 cup packed light brown sugar
- 1/4 cup granulated sugar
- 1 large egg
- 1 teaspoon vanilla extract
- 2 tablespoons molasses
- Cheesecake Filling:
- 24 oz (3 blocks) cream cheese, softened
- 1 cup granulated sugar
- 1/2 cup sour cream, room temperature
- 3 large eggs, room temperature
- 1 1/2 teaspoons vanilla extract
- 1/4 teaspoon salt
- Oatmeal Cream Pie Topping:
- 1/2 cup heavy cream
- 1/2 cup marshmallow creme (fluff)
- 1/4 cup powdered sugar
- 1 teaspoon vanilla extract
- 2-3 store-bought oatmeal cream pies, chopped (for garnish, optional)
Instructions
- Prepare the oatmeal cookie base: Preheat your oven to 350°F (177°C). Line the bottom of a 9-inch springform pan with parchment paper and lightly grease the sides.
- In a medium bowl, whisk together oats, flour, baking soda, cinnamon, and salt. In a separate large bowl, beat the softened butter, brown sugar, and granulated sugar until light and fluffy (about 2-3 minutes). Add the egg, vanilla, and molasses; beat until combined.
- Gradually mix the dry ingredients into the wet ingredients until just combined. Press the oatmeal cookie dough evenly into the bottom of the prepared pan. Bake for 12-14 minutes, or until just set and lightly golden. Cool while you prepare the filling. Lower oven temperature to 325°F (163°C).
- Make the cheesecake filling: In a large bowl or stand mixer, beat the cream cheese until smooth and creamy (about 2-3 minutes). Add sugar and beat again until incorporated. Scrape down the sides of the bowl as needed.
- Add the sour cream, vanilla, and salt. Mix until smooth. Add eggs, one at a time, mixing on low speed after each until just combined. Do not overmix.
- Pour the cheesecake batter over the cooled oatmeal cookie base. Smooth the top with a spatula.
- Bake the cheesecake: Place the springform pan on a rimmed baking sheet. Bake at 325°F (163°C) for 50-60 minutes, or until the edges are set and the center is slightly jiggly. (If desired, use a water bath for gentler baking and fewer cracks.)
- Turn off the oven, crack the oven door, and let the cheesecake cool inside for 1 hour. Remove, then cool to room temperature. Cover and chill in the refrigerator for at least 4 hours, preferably overnight.
- Prepare the topping: In a medium bowl, beat heavy cream until soft peaks form. Add marshmallow creme, powdered sugar, and vanilla. Beat until fluffy and spreadable.
- Spread the marshmallow topping over the chilled cheesecake. Garnish with chopped oatmeal cream pies if desired. Slice and serve cold.
Tips
- Substitutions: You can use store-bought oatmeal cookies for the base in a pinch; just crush and mix with 3 tablespoons melted butter, then press into the pan.
- Room Temperature Ingredients: Make sure cream cheese, eggs, and sour cream are at room temperature for a smooth, lump-free filling.
- Prevent Cracks: Bake cheesecake in a water bath or place a pan of hot water on the oven rack below the cheesecake to create steam.
- Chilling: Don’t rush the chilling time; the cheesecake needs at least 4 hours (preferably overnight) to fully set and develop flavor.
Serving Suggestions
- Top each slice with a mini oatmeal cream pie or a drizzle of caramel sauce for extra indulgence.
- Serve with fresh berries or a dollop of whipped cream to balance the richness.
- For parties, cut into small squares and serve as cheesecake bars on a dessert platter.
- Pair with hot coffee or chai tea for a cozy dessert experience.
Variations
- Gluten-Free: Substitute the all-purpose flour with a 1:1 gluten-free flour blend and use certified gluten-free oats.
- Chocolate Chip: Add 1/2 cup mini chocolate chips to the oatmeal cookie base or sprinkle some on top of the cheesecake before baking.
- Peanut Butter: Swirl 1/3 cup creamy peanut butter into the cheesecake filling before baking for a nutty twist.
- Individual Cheesecakes: Make mini versions using a muffin tin lined with cupcake liners. Press about 1 tablespoon of cookie dough into each, top with filling, and bake for 18-20 minutes.
- No-Bake Version: Use store-bought oatmeal cookies crushed with butter for the base and prepare a no-bake cheesecake filling (cream cheese, whipped cream, and sugar) for a shortcut.
Storage and Reheating
- Refrigerator: Store oatmeal cream pie cheesecake covered in the refrigerator for up to 5 days. Keep it airtight to prevent it from absorbing fridge odors.
- Freezer: Cheesecake freezes well. Wrap slices or the whole cake tightly in plastic wrap and foil, then freeze for up to 2 months. Thaw overnight in the refrigerator before serving.
- Reheating: Cheesecake is best served cold, but if you prefer it slightly warmer, let a slice sit at room temperature for 20-30 minutes before serving. Do not microwave, as this can alter the texture.
Frequently Asked Questions
- Can I make this cheesecake ahead of time?
- Absolutely. This cheesecake is ideal for making ahead since it needs several hours to chill and set. Prepare it up to 2 days in advance and add the topping just before serving for best results.
- How do I prevent my cheesecake from cracking?
- To minimize cracks, avoid overmixing the batter (especially after adding eggs), bake at a lower temperature, and use a water bath or add a pan of water in the oven to increase humidity. Allow the cheesecake to cool gradually in the oven with the door slightly open before chilling.
- Can I use store-bought oatmeal cream pies for the base?
- Yes, you can substitute the homemade oatmeal cookie base with crushed store-bought oatmeal cream pies mixed with melted butter. This shortcut saves time and still delivers that classic flavor, though the texture will be less chewy.
- What’s the best way to slice cheesecake cleanly?
- For neat slices, use a sharp knife dipped in hot water and wiped dry between each cut. This helps prevent sticking and keeps the layers clean and distinct.
- Can I make this recipe gluten-free or dairy-free?
- For gluten-free, use a certified gluten-free flour blend and oats. For dairy-free, substitute plant-based cream cheese and sour cream, and use a vegan butter alternative in the base. The texture may vary slightly, but the flavor will still shine.
- Why is my cheesecake filling lumpy?
- Lumpy filling usually results from using cold cream cheese or overmixing after adding the eggs. Always bring dairy ingredients to room temperature before starting, and mix until just combined for a smooth, creamy texture.
