Step‑by‑Step Instructions for No-Bake Pumpkin Mousse Pie
Step 1: Prepare the Pie Dish
Start by lightly spraying a 9-inch pie dish with non-stick cooking spray. This ensures your delicious Pumpkin Mousse Pie will slide out smoothly when it’s ready to serve. Set the dish aside as you prepare the crust.
Step 2: Make the Crust
In a food processor, pulse the graham crackers until you achieve a fine crumb texture, about 30 seconds. Add melted butter and sugar to the crumbs, then pulse again until the mixture resembles wet sand. This creates the buttery base for your pie.
Step 3: Form the Crust
Press the crumb mixture firmly into the bottom and up the sides of the prepared pie dish. Use your fingers or the back of a measuring cup to create an even layer. Once it’s compacted, place the crust in the freezer for about 15 minutes to set.
Step 4: Mix the Mousse Base
In a mixing bowl, combine the softened cream cheese and pumpkin puree. Using an electric mixer on low speed, blend until the mixture is smooth and well combined. This creamy base is essential for that luxurious texture you want in your Pumpkin Mousse Pie.
Step 5: Add Sweetness and Spice
Sprinkle in the brown sugar, vanilla extract, and pumpkin pie spice. Mix on low speed until everything is well incorporated. The sweet and spiced flavors will enhance the pumpkin, making your mousse irresistibly delicious.
Step 6: Fold in Whipped Topping
Gently fold 2 cups of whipped topping into the pumpkin mixture using a spatula. Be careful not to deflate the mixture; you want to keep it light and airy. This step adds fluffiness, transforming your filling into a mousse-like consistency.
Step 7: Assemble the Pie
Pour the pumpkin mousse filling into the chilled graham cracker crust, spreading it evenly with a spatula. Cover the pie tightly with plastic wrap, then refrigerate for at least 6 hours or overnight. This allows the flavors to meld and the mousse to set perfectly.
Step 8: Prepare for Serving
When ready to serve, take the pie out of the fridge and remove the plastic wrap. Gently spread the remaining whipped topping over the mousse to create a fluffy layer on top. Optionally, dust with ground cinnamon for a lovely finish before slicing.
Step 9: Serve and Enjoy
Slice your No-Bake Pumpkin Mousse Pie into wedges and serve chilled. It pairs beautifully with caramel drizzle or fresh berries, making it a delightful dessert that will impress your friends and family at any gathering!

Make Ahead Options
Preparing this No-Bake Pumpkin Mousse Pie is a dream come true for busy home cooks! You can assemble the entire pie and refrigerate it up to 3 days ahead of time, allowing for effortless entertaining. To prep in advance, make the crust and mousse filling, then combine them and refrigerate the covered pie. This not only allows the flavors to meld beautifully, but it also saves you precious time on the day of your gathering. Just before serving, spread the remaining whipped topping over the mousse for that airy lift, and dust with ground cinnamon. Trust me, it will be just as delicious as when made fresh!

No-Bake Pumpkin Mousse Pie Recipe FAQs
What should I look for in ripe pumpkin puree?
Absolutely! When selecting pumpkin puree, opt for a brand that uses 100% pure pumpkin without any added sugars or spices. If you’re making it at home, choose sugar pumpkins, which are smaller, sweeter, and more flavorful than carving pumpkins. Look for rich, vibrant orange color and a thick consistency that won’t be too watery.
How long does the pie last in the fridge?
Very! Your no-bake pumpkin mousse pie will stay fresh in the refrigerator for up to 2 to 3 days. Make sure it’s covered with plastic wrap or stored in an airtight container to keep it from soaking up any fridge odors and to maintain that delightful creamy texture.
Can I freeze this pumpkin mousse pie, and if so, how?
Yes, you can freeze it! To freeze individual slices, wrap each piece tightly in plastic wrap and place them in a freezer-safe container. The pie can be frozen for up to 1 month. When you’re ready to enjoy, simply thaw the slices in the refrigerator overnight. This method helps maintain the mousse’s consistency, keeping it creamy when served.
What if my mousse doesn’t set correctly?
Not to worry! If your mousse is too soft upon serving, it might need more chilling time. Make sure it has been refrigerated for at least 6 hours or overnight. If you notice your mousse is still too loose, check if all ingredients were at room temperature before mixing, as this can affect the blending process. Next time, consider slightly increasing the cream cheese to ensure a firmer texture.
Are there any dietary considerations I should keep in mind?
Definitely! If you’re making this pie for guests with dietary restrictions, you can easily swap out graham crackers for gluten-free options for those with gluten sensitivities. Also, be cautious with sugar substitutes if you’re catering to diabetics; options like stevia or erythritol could work, but make sure to accommodate for sweetness levels. Lastly, avoid any toppings that may contain allergens for your guests.
Can I make this pie ahead of time?
Absolutely! This no-bake pumpkin mousse pie is ideal for making in advance. You can prepare it 1 to 2 days ahead of your gathering. Just remember to add the whipped topping just before serving to keep it fluffy and light, ensuring your guests enjoy the best texture!
