Ingredients You’ll Need
Don’t let the simplicity of this recipe fool you. Each ingredient plays a crucial role in turning this frosting into a fluffy, melt-in-your-mouth sensation. From the all-purpose flour to the silky butter, every element contributes to the texture, taste, and body of this delightful frosting.
- Flour (5 tbsp): Provides the base for the thickening roux, ensuring the frosting holds its fluffy yet sturdy texture.
- White sugar (1 cup): Balances the flavor perfectly with just enough sweetness; you can even reduce it for a lighter touch.
- Milk (1 cup, warmed): Using full-fat milk enriches the frosting and aids in forming that smooth, custardy roux.
- Vanilla extract (1 1/2 tsp): Infuses the frosting with that classic warm vanilla aroma, essential for this recipe’s character.
- Pinch of salt: Just a touch to enhance the vanilla and balance sweetness beautifully.
- Unsalted butter (225g/1 cup, softened): The heart of the frosting, beaten to pale perfection for lightness and spreadability.
- Cocoa powder (optional, 1/4 cup): Use this if you’re feeling adventurous and want to whip up a chocolate version without losing fluffiness.
How to Make My Secret Less-Sweet, Fluffy Vanilla Frosting Recipe
Step 1: Making the Thickening Roux
Start by combining your flour and sugar in a large saucepan over medium heat, stirring constantly for about 30 seconds to toast the flour slightly without browning. Then slowly whisk in the warmed milk—this is key to avoiding lumps and getting a perfectly smooth custard base. Keep stirring as the mixture thickens into a texture that’s thick and dolloping, like a soft custard. Remove from heat, scrape into a bowl, and cover with cling wrap pressed directly onto the surface to stop a skin from forming. Let it cool to room temperature before using to get the perfect consistency.
Step 2: Preparing the Butter
Next, take your softened unsalted butter and beat it on medium speed for about 3 minutes. The goal is to whip air into it so the color bleaches from yellow to almost white, which gives the frosting its elegantly pale look and light texture. This step is where the magic of fluffiness begins.
Step 3: Combining the Roux and Butter
Switch your mixer to medium speed and gradually add the cooled roux into the butter, one heaped tablespoon at a time. This slow addition takes about a minute and ensures the mixture stays smooth and airy. Once all the roux is incorporated, add vanilla extract and a pinch of salt. Beat the frosting for another 2 to 3 minutes until it holds firm peaks but stays soft and spreadable.
Step 4: Optional Chocolate Twist
If you want to flavor your frosting differently, gently fold in the cocoa powder now. Whip just enough to combine so you keep the luscious fluffiness but gain that rich chocolate kick. Perfect for chocolate cakes craving something lighter than fudge frosting!

Garnishes
This frosting loves company—think fresh berries like raspberries or blueberries to contrast its creamy sweetness, a sprinkle of toasted nuts for crunch, or a dusting of edible gold shimmer to make your desserts sparkle. Each garnish offers a fresh twist to elevate your creation.
Side Dishes
Serve your frosted goodies alongside cozy cups of tea or rich coffee for a lovely afternoon treat. Light lemon bars or crisp biscotti complement the vanilla essence beautifully, creating a balanced dessert spread that keeps everyone coming back for more.
Creative Ways to Present
Use a piping bag fitted with a star tip to create elegant swirls that hold shape splendidly thanks to this frosting’s sturdiness. Or spread it thickly and smoothly for a rustic, homemade look. For something playful, try sandwiching cupcakes with a generous layer in the middle or dip fruit skewers in the frosting for a party-friendly dessert on a stick.
Make Ahead and Storage
Storing Leftovers
This frosting is best enjoyed fresh but if you have leftovers, store them in an airtight container in the refrigerator. Take it out about 1 to 1.5 hours before use to soften it back up without losing that signature fluffiness. On cooler days, cakes frosted with this can rest on the counter comfortably.
Freezing
You can freeze this frosting for up to three months. Just pack it tightly in a freezer-safe container. When ready to use, thaw overnight in the refrigerator, then bring to room temperature and re-whip gently to restore fluffiness before frosting your cakes or cupcakes.
Reheating
This frosting doesn’t need traditional reheating. Instead, warming slightly to room temperature after refrigeration, then whipping it again will bring back its smooth, airy texture. Avoid direct heat which can cause the butter to separate and ruin that delicate balance.
FAQs
Can I use low-fat milk for the frosting?
Yes! While full-fat milk gives the richest flavor and texture, using low-fat milk still works fine. The frosting might be slightly less creamy but will maintain its signature fluffiness and less-sweet charm.
What if I don’t have unsalted butter?
You can use salted butter but reduce the pinch of added salt in the recipe to compensate. Unsalted butter is preferred to give you full control over the seasoning.
How long does the frosting keep once applied to a cake?
On cool days, frosted cakes can stay fresh on the countertop for a day or two. In warmer weather, refrigeration is best to prevent the butter from softening too much, just remember to bring it back to room temperature before serving.
Can this frosting be used for piping intricate designs?
Absolutely! Thanks to the sturdy texture of the roux combined with whipped butter, My Secret Less-Sweet, Fluffy Vanilla Frosting Recipe holds its shape beautifully and can create everything from simple swirls to detailed borders.
Is it possible to make this frosting vegan?
This recipe relies on butter and milk, so to make a vegan version you’d need to substitute with plant-based butters and plant milks, which will alter the texture and flavor. With some experimentation, you could get close, but it won’t exactly match the original fluffy vanilla taste.

- Prep Time: 15 minutes
- Cook Time: 10 minutes
- Total Time: 40 minutes (including cooling time)
- Yield: Enough frosting for one 9-inch layered cake or approximately 12 cupcake-sized servings
- Category: Dessert
- Method: Stovetop
- Cuisine: American
Ingredients
Basic Frosting
- 5 tbsp plain/all-purpose flour
- 1 cup white sugar, regular/granulated (can reduce to 1/2 cup for less sweetness)
- 1 cup milk, warmed (full fat preferred, but 0% fat works)
- 1 1/2 tsp vanilla extract
- Pinch of salt
- 225g / 1 cup unsalted butter, softened but not too soft (about 17°C/63°F)
Chocolate Frosting Option
- 1/4 cup cocoa powder, unsweetened (Dutch processed preferred)
Instructions
- Thickening Roux: Place flour and sugar in a large saucepan over medium heat. Cook, stirring constantly, for 30 seconds to combine and slightly toast the flour. Slowly whisk in the warmed milk, ensuring to keep stirring to avoid lumps. Continue to stir constantly as the mixture heats and thickens into a thick, dolloping custard-like texture. Once thickened, remove from heat and scrape into a bowl. Cover the surface tightly with cling wrap to prevent skin formation and allow to cool completely, about 20 minutes at room temperature and then 30 minutes in the fridge. If refrigerated overnight, bring to room temperature for an hour before using.
- Whip the Butter: Place the softened butter in a mixing bowl. Using a hand mixer or stand mixer with a whisk attachment, beat the butter on medium speed for about 3 minutes until smooth and noticeably lighter in color—pale yellow to almost white. This aerates the butter and creates a fluffy base for the frosting.
- Incorporate the Roux: With the mixer on medium speed, gradually add the thickened roux in heaped tablespoons, taking about one minute to add all. Continue whipping until fully combined and the frosting is smooth.
- Flavor and Finish: Add the vanilla extract and pinch of salt to the mixture. Whip for an additional 2 to 3 minutes until the frosting holds soft peaks and has a fluffy, spreadable texture.
- Optional Chocolate Variation: For chocolate frosting, beat in the unsweetened cocoa powder at the end just until incorporated for a rich chocolate flavor.
- Frost Cakes and Cupcakes: Use the frosting immediately by spreading it with a knife or piping bag. The frosting holds well and can create tall, defined swirls or smooth finishes on desserts.
Notes
- Use caster or superfine sugar if available for optimal texture; reducing sugar to 1/2 cup creates a frosting closer to lightly sweetened whipped cream.
- The butter color affects frosting whiteness; European butters produce a paler frosting, while economical butters are more yellow. To achieve pure white frosting, consider using frosting whitener or adding tiny drops of blue or purple food coloring.
- Softened butter should be cool but pliable (around 17°C/63°F), not too soft to avoid greasy or sloppy frosting.
- Best used freshly made. On cooler days (around 22°C/71°F), the frosting can stay at room temperature once applied. On warmer days, refrigerate frosted items and bring to room temperature 1 to 1.5 hours before serving.
- The flour and milk roux can be prepared up to a day ahead and refrigerated; remove it from the fridge 1 hour before use to return to room temperature.
- Frosting freezes well for up to 3 months; thaw overnight in the refrigerator.
- Recipe inspired by Ermine frosting, known for its balance of sweetness and fluffy texture.
