Why you’ll love this recipe!
What ingredients do I need?
- Unsalted Butter: The base of the frosting, whipped until light and fluffy
- Powdered Sugar: Sweetens and gives structure to the buttercream
- Vanilla Bean Paste: Adds rich vanilla flavor and visible vanilla specks
- Fine Sea Salt: Balances sweetness and enhances flavor
- Heavy Cream: Creates a light, smooth, spreadable texture
- Rainbow Sprinkles: Add color and fun throughout the frosting
Recipe Variations
- Chocolate Funfetti Frosting: Add ¼ cup sifted cocoa powder to the frosting
- Cupcake Swirl Version: Chill briefly before piping for sharp swirls
- Extra Vanilla: Increase vanilla for a more pronounced flavor
- Chocolate Sprinkles: Use chocolate sprinkles isn’t of rainbow for a different look
Pro Tips
- Beat your butter on medium-high speed for 3–4 minutes until it’s very pale, fluffy, and smooth. This incorporates air, giving the frosting that light bakery-style texture.
- Sift powdered sugar if you can. This helps prevent any lumps and ensures a silky smooth frosting.
- Add the powdered sugar gradually. Incorporate it ½ cup at a time on low speed to avoid a powder cloud in your kitchen.
- Use heavy cream carefully. Add 1 tablespoon at a time to control consistency. More cream equals softer frosting; less cream equals thicker frosting perfect for piping.
- Fold sprinkles in by hand. This is key to keeping the colors bright and preventing bleeding. Use a spatula, not the mixer.
- If your frosting feels runny or too soft to pipe, chill for 10–15 minutes and then re-whip lightly before using.
- Avoid overmixing the sprinkles. Overmixing can dull the colors and deflate your fluffy buttercream.
- Use the right sprinkles: Rainbow sprinkles hold their shape and color in frosting better than nonpareils or natural dye sprinkles.
- Chilled frosting is easier to pipe for sharp swirls; softened frosting is perfect for a smooth spread on cakes and cookies.
Can I Substitute?
Yes! Like always though, any substitutions made to the recipe can result in a change in texture and/or flavor.
- Vanilla Bean Paste: Substitute with vanilla extract
- Heavy Cream: Use whole milk or half and half if needed
- Unsalted Butter: Salted butter can be used; omit the added salt
- Rainbow Sprinkles: Use bake stable sprinkles for best color retention (natural dye sprinkles will bleed)
Dietary Substitutions
Dairy Free: Use plant based butter and dairy free cream alternatives
Leftovers and Storage
- Store frosting in an airtight container in the refrigerator for up to 5 days.
- Bring to room temperature and re-whip briefly before using.
- Frosted baked goods can be stored at room temperature for up to 24 hours depending on environment.
But, I Still Have A Few Questions…
What type of sprinkles work best in buttercream?
Rainbow sprinkles or bake stable sprinkles are ideal. They maintain vibrant colors and don’t melt into the frosting, keeping a beautiful speckled appearance.
Can I use natural dye sprinkles?
Natural or plant based colored sprinkles (made with beet juice, turmeric, spirulina, etc.) tend to bleed their color into the frosting. This can turn your frosting pink, green, or orange and make the colors look muted or streaky. Stick to traditional rainbow sprinkles for a classic funfetti look.
Can I pipe this frosting?
Yes! If frosting is too soft, chill it 10–15 minutes and then re-whip lightly. It holds shape beautifully for swirls, rosettes, and decorative piping.
Can I make this frosting ahead of time?
Yes. Store in an airtight container in the refrigerator for up to 5 days. Bring to room temperature and re-whip briefly before using.
Can I use this frosting on cookies or bars?
Absolutely. This frosting spreads smoothly on cookies and bars, and the sprinkles add a fun pop of color. Chill briefly if you want the frosting to hold shape.
Why is my frosting too soft?
Butter at too high a temperature or adding too much cream can make frosting soft. Chill for 10–15 minutes and re-whip lightly before piping.
Can I make this frosting dairy free?
Yes. Use plant based butter and a dairy free cream alternative. Keep in mind that texture may vary slightly.
Can I add flavor variations?
Yes! Vanilla bean paste is classic, but almond, lemon, or coconut extracts can be used for a fun twist.
How much frosting does this make?
Enough to frost 12–18 cupcakes or one 8–9 inch layer cake. Adjust quantities proportionally for larger cakes or multiple layers.
Why fold sprinkles in instead of mixing?
Folding by hand ensures the colors stay vibrant and prevents the sprinkles from breaking or bleeding into the frosting.
