I love a dessert that's simple to make but still feels like something special, and this Keto Raspberry Marshmallow Cream Pie checks every box. The filling comes together with just five ingredients, and the secret is sugar-free marshmallows. I know that might sound unexpected, but trust me...they melt into the milk to create an incredibly smooth, fluffy filling that sets up beautifully in the refrigerator.

One of my favorite things about this recipe is that the only baking required is the almond flour crust. Once that's done, the rest of the pie comes together in just a few easy steps.

I've served this pie to family members who had no idea it was low carb, and it disappears every time. In fact, my teenager couldn't even tell it was made with sugar-free ingredients. That's always my goal when I develop recipes...to create food that tastes just as good as the traditional version so everyone at the table can enjoy it.

Storage information

Store the raspberry marshmallow pie covered in the refrigerator for up to 5 days. Since the filling contains whipped cream and cream cheese, it’s best kept chilled until you’re ready to serve.

Can it be frozen?

Yes! This pie freezes surprisingly well. Wrap the pie tightly in plastic wrap, then a layer of aluminum foil, or store individual slices in an airtight freezer-safe container. Freeze for up to 2 months. Thaw overnight in the refrigerator before serving. The texture will be slightly firmer straight from the freezer, which some people actually prefer for a frozen-dessert style treat.

Step by Step Instructions

  1. Preheat oven & prepare pie plate

    Preheat oven to 350 degrees F and spray the inside of an 8” pie plate with cooking oil.

  2. Make crust

    In a food processor, add almond flour, coconut flour, brown sugar sweetener, baking powder, xanthan gum and salt. Pulse a few times to combine. Add cubed butter and vanilla. Pulse until coarse crumbles form.

    For this step

    • 1 ¼ cup almond flour
    • 3 tablespoons coconut flour
    • 1 tablespoon brown sugar substitute sweetener
    • 1/2 teaspoon baking powder
    • 1/2 teaspoon xanthan gum
    • 1/4 teaspoon salt
    • 4 tablespoons unsalted butter, chilled & cubed
    • 1/2 teaspoon vanilla extract
    Almond flour pie crust ingredients blended in a food processor until the mixture resembles coarse crumbs.
  3. Bake the crust

    Press the crust into the pie plate. Make sure you press up the sides too and form an even layer. Bake for 9 minutes. Remove from oven and set aside to cool.

  4. Strain the raspberries

    Pour raspberries into a fine mesh strainer. Using a paper towel, press on the raspberries to get excess moisture and liquid to push through the strainer. Keep the strained raspberries and discard the liquid.

    For this step

    • 10 oz frozen raspberries, thawed

  5. Make whipped cream

    In a medium bowl, pour in heavy cream. Using an electric mixer on medium speed, beat the cream until it starts to thicken a bit. Then add powdered sugar-free sweetener. Increase the speed to high and beat until stiff peaks form. Set aside.

    For this step

    • 1 cup heavy cream
    • 1/4 cup powdered sugar-free sweetener

  6. Melt marshmallows

    To a large glass microwave-safe bowl, add marshmallows and milk. Microwave for 1-2 minutes intervals, stirring in between until the marshmallows are melted and mixture is smooth.

    For this step

    • 35 large sugar-free marshmallows
    • 1/2 cup milk of choice
    The marshmallow cream filling blended until smooth before adding the raspberry puree.
  7. Combine ingredients

    Stir in strained raspberries until combined. Add half of the whipped cream and fold in until combined. Carefully fold in remaining in order to retain the fluffiness of the mixture.

  8. Pour into crust and refrigerate

    Scoop mixture onto crust, smooth out the top and refrigerate for 2 hours or overnight.

Frequently Asked Questions

Can I use fresh raspberries instead of frozen?

Yes! Fresh raspberries work just as well. If you're using fresh berries, you can skip the thawing step, but I still recommend gently pressing them through a fine mesh strainer to remove excess juice. This helps the filling set properly without becoming too soft.

Can I use a different fruit?

Absolutely. This recipe is very versatile. Try strawberries, blackberries, blueberries, or even a combination of mixed berries. Just be sure to strain out any excess liquid before folding the fruit into the filling.

What sugar-free marshmallows do you recommend?

I use ChocZero sugar-free marshmallows because they melt smoothly and have a classic marshmallow flavor. They contain just 1 gram of carb per 6 marshmallows, making them a great option for keto and low-carb desserts. But there are other brands out there. Look them up on Amazon.

Can I make this pie ahead of time?

Yes! This is actually a great make-ahead dessert. Prepare the pie the day before serving and let it chill overnight. The filling firms up nicely, and the flavors become even better after several hours in the refrigerator.

Made this for the first time last week and the flavor was genuinely impressive, but the filling came out too loose to slice cleanly. I drained the raspberries like the recipe says but probably didn’t press them quite dry enough. Is that the main culprit for a soft set, or is there something else I should focus on next time?

Do the marshmallows melt completely into the filling?

Had no idea you could make a marshmallow cream filling with just five ingredients. Made this last weekend and everyone loved it.

That filling is honestly so easy. Try it the night before next time. It firms up and the raspberry really comes through after a few hours in the fridge, Stephanie.

The filling texture when fully chilled, that almost-mousse lightness, is what keeps me making this. Third time now, and I’ve started pressing the raspberries in the strainer longer than it seems necessary before folding in the whipped cream. Firms up the set and the slices hold a cleaner edge.

The longer press matters more than it seems like it should.
