Jump to Recipe Print Recipe

It’s somewhere between a cheesecake mousse and a fluffy fruit dip. You can enjoy it by the spoonful, serve it as a dip with fresh berries, or even use it as a base for a low carb dessert salad. Best of all, it comes together with just three simple ingredients and fits perfectly into a keto lifestyle.

Why You’ll Love This Strawberry Fluff

This is one of those recipes you can throw together in minutes when you need something sweet but don’t want to bake. The texture is light and airy, yet stable enough to hold its shape. It’s thick enough to layer, pipe, or scoop onto a fruit tray.

The flavor is similar to strawberry cheesecake filling, but without the crust or added sugar. When made with sugar-free gelatin, it stays low carb and completely guilt free.

I personally love serving it as a dip with fresh strawberries. The combination of creamy fluff and juicy berries is simple but always a hit. It’s also a beautiful dessert option for baby showers, bridal showers, Valentine’s Day, Easter, or summer parties thanks to its soft pink color.

The traditional version of strawberry fluff uses marshmallow creme and sugary gelatin. This keto version skips both and still delivers the same creamy, sweet flavor.

Ingredients You’ll Need

To make this keto strawberry fluff, you only need three main ingredients:

1 package sugar-free strawberry gelatin (such as Simply Delish) plus water as directed
1 (8-ounce) block cream cheese, softened to room temperature
2 cups heavy whipping cream

That’s it. Simple, basic ingredients that create something surprisingly impressive.

How to Make Keto Strawberry Fluff

The most important tool for this recipe is an electric mixer. A stand mixer with a whisk attachment works best, but a handheld electric mixer will also do the job. The fluffy texture depends on proper whipping, so mixing by hand won’t give the same result.

Start by placing the room temperature cream cheese into a large mixing bowl. Beat it until completely smooth and creamy. This step is essential because the cream cheese forms the base of the fluff. If it’s lumpy here, it will stay lumpy later.

In a separate small bowl, prepare the sugar-free gelatin. If using Simply Delish, dissolve it in cold water as directed. It does not require boiling water. If using Jello brand, prepare it only up to the point before adding the extra cold water. Let it cool completely to room temperature before using so it doesn’t melt the cream mixture.

With the mixer running on low speed, slowly pour the gelatin mixture into the whipped cream cheese. Add it in a steady stream to prevent splashing. Once incorporated, scrape down the sides of the bowl and increase the speed to medium until the mixture becomes slightly fluffy.

Reduce the speed to low again and slowly pour in the heavy cream. After it’s combined, scrape the bowl one more time to ensure everything is evenly mixed.

Now increase the speed to high and whip for about one minute. This final whip is what creates that light, airy texture. Be careful not to overmix. If you whip too long, the heavy cream can separate and begin turning into butter.

If you’d like to turn this into a fluff salad, gently fold in chopped strawberries or other fruit at this stage. For softer fruits like pineapple or mandarin oranges, fold them in by hand to maintain texture.

Transfer the mixture into a bowl with a tight-fitting lid or cover with plastic wrap. Refrigerate overnight to allow it to fully set and thicken.

Storage and Make Ahead Tips

The finished fluff should be stored covered in the refrigerator and will stay fresh for up to five days.

If you mix fruit directly into the fluff, keep in mind that the fruit will release moisture over time, which can thin the mixture. For best results, add fresh fruit right before serving if you want it to last longer.

Variations and Creative Ideas

You can lighten the recipe slightly by replacing heavy cream with sugar-free whipped topping folded in at the end.
Try layering this fluff with crushed gluten-free graham crackers or low carb cereal to create mini cheesecake trifles.
Experiment with different sugar-free gelatin flavors like raspberry, lemon, lime, or orange for a fun twist.
For a smoother, pudding-like consistency, fold in prepared sugar-free vanilla pudding at the end.
You can also pipe the mixture into silicone molds, freeze until firm, then dip in melted sugar-free chocolate to make strawberry cheesecake bon bons.
