Making a Weight Watchers-friendly Marshmallow Fluff is a brilliant way to enjoy a sweet, creamy topping without blowing your points. This version is light, airy, and perfect for dipping fruit, adding to hot chocolate, or using in recipes like a light “Fluffernutter” sandwich.
The key is using a sugar-free base to keep the point value low.
☁️ Weight Watchers Marshmallow Fluff (2-3 Points for the Entire Batch!)
This recipe uses gelatin to create that classic fluffy texture without the heavy sugar load of the store-bought version.
📝 Ingredients
-
1 envelope (¼ oz / 7g) unflavored gelatin
-
½ cup (120ml) cold water, divided
-
½ cup (120ml) boiling water
-
1 tsp vanilla extract
-
½ cup (120ml) granulated sugar-free sweetener that measures like sugar (e.g., Lakanto Monk Fruit or Erythritol blends)
-
Pinch of salt
Optional for stability:
-
1 tbsp light corn syrup (adds 1-2 points to the total batch, but improves texture)
👩🍳 Instructions
-
Bloom the Gelatin: Sprinkle the unflavored gelatin over ¼ cup of cold water in a large, heatproof bowl (or your stand mixer bowl). Let it sit for 5 minutes to “bloom” and become solid.
-
Dissolve the Gelatin: Pour the ½ cup of boiling water into the bloomed gelatin. Whisk continuously until the gelatin is completely dissolved and the mixture is clear.
-
Whip to Soft Peaks: Using an electric hand mixer or a stand mixer with the whisk attachment, beat the gelatin mixture on high speed. Gradually add the sugar-free sweetener and pinch of salt. Continue whipping for about 5-7 minutes until it becomes thick, white, and forms soft peaks. It should resemble the consistency of marshmallow cream.
-
Add Flavor: Beat in the vanilla extract until just combined.
-
Use Immediately or Store: Your fluff is ready to use! It’s best fresh but can be stored in an airtight container in the refrigerator for up to 5 days. It may separate slightly; just give it a quick stir before using.
💡 Pro Tips & WW Point Notes
-
Sweetener Choice is Crucial: The success of this recipe depends on a sugar-free sweetener that can be whipped. Powders like allulose or monk fruit/erythritol blends work best. Liquid sweeteners will not work.
-
Why Corn Syrup is Optional: A tiny amount of light corn syrup helps inhibit crystallization, giving the fluff a smoother, more stable texture that lasts longer. You can omit it to keep points as low as possible.
-
Point Calculation (Approximate):
-
The primary ingredients (gelatin, water, vanilla, salt) are 0 points.
-
The points come entirely from the sugar-free sweetener. Most are 0 points per serving.
-
This makes the entire batch roughly 0-3 points, depending on your specific sweetener. Always calculate in your WW app for the brands you use.
