How to Whiten Buttercream (and Cancel That Yellow Tint!)
Have you ever made buttercream expecting it to be bright white, only to end up with a creamy or yellow frosting instead?
If you’ve been wondering “Why isn’t my buttercream white?”, “Why is my buttercream yellow?”, or “How do I make buttercream white?”, you’re not alone.
The natural yellow color comes primarily from the butter itself. Butter contains beta-carotene, a natural pigment found in grass and plants that cows eat. Butter made from grass-fed cows often contains more beta-carotene, giving it a richer yellow color. While that’s completely natural-and often a sign of good-quality butter-it can make achieving a crisp white buttercream more challenging.
The good news is that there are several simple ways to make buttercream appear much whiter.
1. Start with a Paler Butter
Not all butter is the same color.
Some brands are naturally much paler than others, while European-style and grass-fed butters often have a deeper yellow hue.
If your goal is a bright white buttercream, experiment with different butter brands available where you live. Starting with a paler butter gives you a much better base before you even begin color correcting.
2. Whip Your Buttercream Until It Becomes Lighter
Whipping incorporates air into the buttercream, making it appear lighter in both texture and color.
This alone won’t produce a brilliant white buttercream, but it does help create a paler base before adding any white food coloring or color correction.
Just avoid over-whipping, as too much air can leave your buttercream full of bubbles. Once it’s fully emulsified, you can mix slowly with a paddle attachment to help smooth it back out.
3. Add White Food Coloring
One of the easiest ways to brighten buttercream is by adding white food coloring.
For the best results, add it after your buttercream has fully emulsified, allowing it to distribute evenly throughout the frosting.
There are several options available:
White Gel Food Coloring
White gel food coloring is a good all-round choice. It blends easily into buttercream and brightens the overall color without noticeably affecting the consistency.
Oil-Based White Food Coloring
Oil-based white food coloring works particularly well in buttercream because it disperses beautifully through high-fat mixtures. It’s also an excellent choice for white chocolate ganache.
Titanium Dioxide
Titanium dioxide has long been used as one of the strongest whitening pigments available for buttercream.
If it’s permitted where you live and you choose to use it, start with a small amount and mix thoroughly. A good starting point is around 6–8 g per 1 kg of buttercream, approximately 0.6–0.8% by weight, then adjust if needed.
Give the buttercream time to sit before adding more, as the whitening effect often becomes more noticeable after it has fully dispersed.
Important note: Titanium dioxide regulations vary around the world, so always check your local food regulations before using it.

European Union – Banned for use in food since 2022 following an EFSA safety assessment.
United States – Permitted. The FDA allows titanium dioxide in food at levels of up to 1% by weight of the finished food.
Canada – Permitted. Health Canada allows titanium dioxide in food, subject to a maximum of 1% by weight of the finished food.
United Kingdom – Currently permitted in food and does not follow the European Union ban.
Australia & New Zealand – Permitted. FSANZ reviewed the EFSA findings and has continued to allow its use.
Japan – Permitted and commonly used in confectionery.
Many countries across Asia, the Middle East, Africa, and South America – Generally permitted under national food regulations, many of which align with Codex Alimentarius standards.
4. Use Violet to Neutralize Yellow
This is one of my favorite tricks-but it only works when used correctly.
Violet sits opposite yellow on the color wheel, so a tiny amount can help neutralize the warm undertones in buttercream, making it appear whiter.
Notice I said neutralize, not whiten.
Violet doesn’t add whiteness or opacity. Instead, it balances the yellow undertones so the buttercream looks cleaner and more neutral.
The amount you use is incredibly important.
Start with the tiniest amount possible. Dip the tip of a toothpick into violet gel food coloring, touch it into the buttercream, and mix thoroughly before deciding whether it needs more.
If you add just the right amount, the yellow tone softens and the buttercream appears brighter.
If you add too much violet, the buttercream can begin to take on a grey, lavender, or purple tint.
The exact amount needed will vary depending on how yellow your butter is and the strength of your food coloring, so always work gradually.
5. Real Vanilla vs Clear Vanilla
You’ll often hear people recommend using clear vanilla to make buttercream whiter.
While clear vanilla can help prevent additional color from being added to the buttercream, most clear vanilla products are imitation vanilla.
Personally, I prefer using pure vanilla extract because I love the depth of flavor it adds. I would rather accept a slight creamy tint than compromise on flavor simply to make the buttercream look whiter.
If achieving the whitest possible finish is your only priority, clear vanilla is an option. Otherwise, good-quality real vanilla is well worth the slight warmth it may add.
FAQs:
Why Is My Buttercream Still Not White?
If you’ve followed all these steps and your buttercream still isn’t perfectly white, it may simply be because the natural yellow pigment in the butter is too strong to cancel completely.
Several factors influence the final color, including:
- The brand of butter you’re using.
- How yellow the butter is naturally.
- The type and strength of your white food coloring.
- How much violet food coloring you use.
- The flavorings you’ve added.
- Whether titanium dioxide is permitted and available where you live.
Violet can neutralize the yellow undertone, but it doesn’t remove the pigment already present in the butter. If the buttercream remains creamy or ivory after color correction, adding more violet may make it look lavender or purple rather than noticeably whiter.
Sometimes the best achievable result is a soft white or ivory rather than a brilliant paper white—and that is completely normal for a butter-based frosting.
Why Did My Buttercream Turn Purple Instead of White?
If your buttercream has turned lavender or purple, the violet has overtaken the yellow undertone.
This doesn’t necessarily mean the technique doesn’t work. It usually means the buttercream had already reached the point where the yellow was sufficiently neutralized, but additional violet was added.
The easiest way to avoid this is to add violet in extremely small amounts and mix thoroughly before deciding whether to add more.
The amount required can vary dramatically depending on the natural color of your butter and the concentration of your food coloring, so there is no single measurement that works for every batch.
The Best Way to Make Buttercream White
For the brightest result, combine several techniques:
- Start with the palest butter you can find.
- Whip the buttercream until it is fully emulsified and lighter in color.
- Add white food coloring after the buttercream has emulsified.
- Neutralize the remaining yellow with a tiny amount of violet.
- Allow the buttercream to rest before making any final adjustments.
Using these techniques together will give you the brightest white buttercream possible while still maintaining great flavor and texture.
