Ingredients for Fat Free Icing
Seven simple plant-based ingredients create this light, guilt-free topping for cakes and cupcakes.
| Ingredient | Amount | Notes |
|---|---|---|
| Powdered Sugar 🍚 | 4 cups | Sifted for smooth texture |
| Aquafaba 🥫 | ¾ cup | Chilled chickpea brine |
| Vanilla Extract 🌿 | 2 tsp | Pure extract preferred |
| Almond Milk 🥛 | 2 tbsp | Unsweetened for balance |
| Cream of Tartar 🧂 | ½ tsp | Stabilizes the meringue |
| Salt 🧂 | ¼ tsp | Fine grain for even distribution |
| Lemon Juice 🍋 | 1 tsp | Freshly squeezed for brightness |

The aquafaba is non-negotiable here—drain a can of chickpeas (save the beans for hummus) and use that viscous liquid. Organic chickpeas often yield more aquafaba, and it whips up stiffer. Powdered sugar quality matters: Domino or C&H are reliable brands with fine grains that dissolve smoothly. For the vanilla, pure extract (not imitation) adds depth.
No aquafaba? Flax egg foam (3 tbsp water + 1 tbsp ground flaxseed, whipped) works in a pinch but lacks the same volume. Swap almond milk for any unsweetened plant milk—soy or oat are neutral. Out of cream of tartar? White vinegar or lemon juice at half the amount can substitute, though the icing may be slightly less stable.
This keeps 1 week refrigerated in an airtight container. Freeze for up to 3 months—just rewhip before using. Best used within a few days for peak fluffiness.
Why You’ll Love This Recipe
- 5-Minute Whip: I just dump the powdered sugar, aquafaba, and a splash of almond milk in a bowl and it’s ready before the cake cools.
- Sweet Vanilla Cloud: The vanilla extract makes it taste like a classic bakery frosting, but lighter—no weird aftertaste, just pure sweetness.
- Cupcake or Cake: I’ve piped it onto cupcakes for birthdays and spread it thin on sheet cakes for potlucks with zero issues.
- Pantry Staples Only: Between us, I always have these ingredients already, so I’m never making a last-minute store run for butter.
Step-by-Step Instructions for Fat Free Icing
Master this technique for a stable, cloud-like frosting that pipes beautifully without any added fat.
Step 1: Whip the Aquafaba to Soft Peaks
In a spotlessly clean mixing bowl, combine the 0.75 cup Aquafaba with the 0.5 tsp Cream of Tartar. The acidity from the cream of tartar stabilizes the egg-white substitute, allowing it to hold air bubbles effectively. Ensure your beaters are equally clean—any residue of grease will prevent proper whipping.
Using a stand mixer fitted with the whisk attachment, beat on medium-high speed until frothy, about 2 minutes. Gradually increase to high speed and continue whipping for an additional 5-7 minutes until soft peaks form. You’ll know it’s ready when the whisk leaves trails that hold their shape briefly before melting back into the mixture.
Step 2: Gradually Incorporate the Powdered Sugar
With the mixer running on low speed, slowly add the 4 cups Powdered Sugar, about ½ cup at a time. This gradual addition prevents clumping and ensures the sugar dissolves completely into the aquafaba base. Sifted powdered sugar is essential here—it eliminates lumps and creates a silky-smooth texture.
After all the sugar is incorporated, increase the speed to medium-high and whip for another 3-4 minutes. The mixture should become thick, glossy, and hold stiff peaks when the whisk is lifted. Watch for the bowl to feel cool to the touch; this indicates proper aeration.
Step 3: Add Flavorings and Final Adjustments
Reduce the mixer speed to low and add the 2 tsp Vanilla Extract, 1 tsp Lemon Juice, 0.25 tsp Salt, and 2 tbsp Almond Milk. The vanilla and lemon juice provide depth and brightness, while the salt balances the sweetness. Use pure vanilla extract for the best flavor profile.
Increase the speed to medium and mix for an additional 1-2 minutes until fully homogeneous. The texture should be smooth, spreadable, and hold its shape when piped. If the icing appears too thick, add the almond milk a ½ tablespoon at a time until the desired consistency is reached. Unsweetened almond milk keeps the flavor neutral.
Step 4: Test and Adjust Consistency
Stop the mixer and assess the icing’s consistency. For piping, it should hold a defined peak when the whisk is lifted. For spreading, it should be slightly softer but still maintain structure. If it’s too thin, whip for another 1-2 minutes—the aquafaba will often tighten up with additional air incorporation.
If the icing still seems loose, add an additional 1-2 tablespoons of sifted powdered sugar and whip until incorporated. Avoid overmixing at this stage, as it can cause the icing to deflate. The final product should be glossy, stable, and ready to use immediately for frosting cakes or cupcakes.
Pro Tips For Making Fat Free Icing
- Whip Aquafaba First: Beat the aquafaba with cream of tartar for 2-3 minutes until foamy before adding powdered sugar. I learned this the hard way—adding sugar too early just makes a grainy mess.
- Sift Powdered Sugar: Always sift your powdered sugar first, even if the bag says “pre-sifted.” Those tiny lumps will ruin the smooth texture you’re after.
- Skip Cold Almond Milk: Use room temperature almond milk to prevent seizing up the icing. Cold milk can make it clump instantly, and nobody wants to start over.
- Add Vanilla Last: Fold in the vanilla extract at the very end to preserve its flavor. Adding it earlier can get lost in the mixing process—sounds weird, but it works.

Flax egg foam (3 tbsp water + 1 tbsp ground flaxseed, whipped) works as a substitute. Note that it may yield slightly less volume and stability.
How long does this icing hold its shape?
It maintains stability for 1-2 hours at room temperature. For longer events, refrigerate the decorated dessert until serving.
Can I color this icing?
Yes! Add gel-based food coloring during the final mixing stage. Avoid liquid coloring as it can alter the consistency.
Why did my icing collapse?
This usually happens if the bowl or beaters weren’t clean or if overmixed after reaching stiff peaks. Start over with spotless tools.
