Fluffy no-bake pumpkin pie

No bake marshmallow pumpkin pie transforms the traditional Thanksgiving dessert into something magically light and airy. This innovative take combines the familiar warm spices of pumpkin pie with the pillowy sweetness of marshmallows to create a dessert that's both nostalgic and refreshingly different. The filling is impossibly fluffy and cream-like, nestled perfectly in a crisp graham cracker crust – all without ever turning on your oven.

The first time I made this for my family's Thanksgiving gathering, my sister-in-law who claims to "hate pumpkin pie" went back for seconds and then asked for the recipe. There's something about the marshmallow's transformation that takes pumpkin to an entirely different level. Now it's requested even for non-holiday gatherings – my niece specifically asked for it at her graduation party last spring!

Essential Ingredients

• Large Marshmallows: These create the magical fluffy texture that makes this pie special – standard size (not mini) work best as they melt more evenly
• Pure Pumpkin: Be absolutely certain to use 100% pure pumpkin (not pumpkin pie filling) for the proper consistency and pure pumpkin flavor
• Pumpkin Pie Spice: This convenient blend contains the perfect balance of cinnamon, nutmeg, ginger, and cloves to create that authentic pumpkin pie flavor
• Cool Whip: Provides additional lightness and structure to the filling – while homemade whipped cream can work, Cool Whip delivers consistent results
• Store-Bought Graham Cracker Crust: The 6-ounce size provides the perfect ratio of crust to filling and holds up beautifully to the no-bake filling

Step-by-Step Instructions

Step 1:

Melt the marshmallows with pumpkin and spices. In a medium saucepan over low heat, combine 40 large marshmallows, 1 cup pure pumpkin, 1 teaspoon ground cinnamon, 1 teaspoon pumpkin pie spice, and ¼ teaspoon salt. This process requires patience – keep the heat low to prevent scorching and stir constantly with a silicone spatula to help the marshmallows melt evenly and incorporate with the pumpkin.

Step 2:

Cool the mixture completely. Transfer the warm pumpkin-marshmallow mixture to a mixing bowl and allow it to cool to room temperature, which takes approximately 30-45 minutes. This cooling step is non-negotiable – adding Cool Whip to a warm mixture will cause it to deflate and lose its structure completely.

Step 3:

Incorporate the Cool Whip. Once the pumpkin mixture has cooled completely, fold in an entire 8-ounce container of thawed Cool Whip. Use gentle folding motions rather than vigorous stirring to maintain as much air in the mixture as possible. The color will lighten significantly, transforming to a beautiful pale orange.

Step 4:

Fill the crust and chill. Pour the finished filling into the graham cracker crust, using a spatula to create a smooth, even surface. Cover with the plastic lid that comes with the crust (or plastic wrap if using homemade crust) and refrigerate for at least 8 hours or preferably overnight to allow the pie to set properly.

Step 5:

Garnish before serving. Just before serving, top the pie with additional whipped cream if desired. For an extra special presentation, pipe whipped cream around the edges and sprinkle with a little cinnamon or crushed graham crackers for color and texture contrast.

Pin it

I particularly love the graham cracker crust with this pie. The subtle honey notes and crisp texture create the perfect counterpoint to the soft filling. When making this for my mother's birthday (she's a pumpkin fanatic), I sometimes add a thin layer of cream cheese mixture on the bottom of the crust before adding the pumpkin filling – it adds a tangy note that beautifully complements the sweetness.

The Perfect Balance of Flavors

What makes this pie truly special is the balance between the earthy pumpkin and sweet marshmallow. Neither ingredient overpowers the other, creating instead a harmonious blend that tastes like the best parts of both. The pumpkin provides depth and familiar spice notes while the marshmallow brings a lightness and subtle vanilla flavor. I've found that using standard-sized white marshmallows (not flavored or colored varieties) gives the cleanest flavor that lets the pumpkin shine.

Make-Ahead Convenience

One of the greatest advantages of this no-bake pie is its make-ahead potential. I often prepare it two days before serving with excellent results. The extra time in the refrigerator actually improves the texture and allows the spices to fully permeate the filling. This makes it perfect for busy holiday meal preparation when oven space and last-minute timing are concerns. Just keep it covered in the refrigerator and add any fresh toppings just before serving.

Serving Suggestions

While this pie is delicious on its own, I've discovered some wonderful ways to elevate it further. Try serving each slice with a drizzle of salted caramel sauce for a sophisticated sweet-salty contrast. For a textural element, sprinkle toasted pecans or walnuts on top just before serving. During the holidays, I sometimes infuse the Cool Whip with a tablespoon of bourbon before folding it into the pumpkin mixture – it adds a subtle warmth that adults appreciate.

I discovered this recipe during a Thanksgiving when our oven unexpectedly stopped working. What began as a desperate substitution has become a beloved tradition. There's something special about the way the marshmallows transform ordinary pumpkin puree into something so ethereal. While I still appreciate a classic baked pumpkin pie, this no-bake version has earned its place as a year-round favorite that always disappears quickly from the dessert table.
