Gluten Free Buttercream Frosting
This classic gluten free frosting recipe is easy to make and perfect for all of your favorite cakes, cupcakes or even cookies. This buttercream recipe requires just a few simple ingredients and takes about 10 minutes to whip up.

Vanilla buttercream is truly one of my favorite things in the world. Well, vanilla anything is my favorite. But vanilla gluten free frosting really takes the cake. Literally, lol.
This is my go to recipe that yields a silky, smooth, rich buttercream for all of your favorite cakes, cupcakes and more.
All you need for this recipe is butter, powdered sugar, a little cream, vanilla and salt. The salt might seem like a strange addition, but I promise, the smallest pinch really helps round out the flavors.
The most important thing to consider when making buttercream is the temperature of your butter. You want room temperature butter, and I find the fastest way to bring it to room temperature is to just stick it in my bra for a few minutes.
Seems odd, but it works! You can also add hot water to a bowl and add a second, smaller bowl with the butter to soften it.

Key ingredients
BUTTER. Buttercream frosting of course has a base of butter! You need 1 1/2 cups, or three sticks of room temperature butter.
POWDERED SUGAR. This is what will sweeten the frosting and when combined with the butter will make it nice and fluffy.
VANILLA. A bit of vanilla and salt really round out the flavors here.
CREAM. This is needed to thin the frosting if it gets too thick but also helps make it creamier. You can use dairy or non-dairy here.

How to make gluten free buttercream frosting
Add the room temperature butter to a bowl or bowl of a stand mixer. I highly recommend a stand mixer if you have one because it can get tiring holding the hand mixer for too long! A hand mixer will work if that’s all you have.
Beat for about 5 full minutes.
Beat in the powdered sugar two cups at a time while the mixer is on low. Let run for an additional 5 minutes.
Beat in the cream and vanilla until completely creamy and well combined. If it seems too thin, add in another 1/2 cup of powdered sugar at a time until it reaches your desired consistency.
WANT TO SAVE THIS RECIPE?
Pipe onto cupcakes or add to cakes. Store any extra in the fridge for up to 2 weeks.

Make it chocolate frosting!
Simply add in 1/2 cup of cocoa powder right after you beat in the sugar and decrease the amount of powdered sugar to about 4-5 cups to account for the extra dry ingredients.
You can start with less cocoa if you prefer a more mild flavor/color, or add more for extra richness. If you notice it’s too thick, just add a bit of cream to thin it out.

Do you need to sift the powdered sugar?
I used to always sift powdered sugar for buttercream, but have come to realize you don’t really have to. If you notice your sugar is particularly clumpy, then it might help to, but you absolutely don’t have to.
When you mix the frosting for long enough, any clumps should smooth out, so sifting is just an extra step.
How do you thicken frosting?
More powdered sugar! If you add too much cream or the frosting simply isn’t thick enough, just beat in an extra 1/2 cup of powdered sugar until it reaches a thicker consistency.

Can you make frosting without butter?
Unfortunately, butter is a key ingredient in buttercream! There are other types of gluten free frosting or icings that don’t require butter, but American buttercream requires quite a bit of butter.
A simple glaze with about 1 1/2 cups of powdered sugar, 2-3 tablespoons of cream and a splash of vanilla is delicious drizzled over certain recipes!
However, for layer cakes and cupcakes, I recommend sticking with buttercream.
Make it vegan!
To make this frosting vegan, just swap the butter for dairy free butter. I suggest the Earth Balance vegan butter sticks. Follow all of the same recipes steps as usual.

Easy and yummy! I used coconut cream and made it a little different flavor with more depth. Delish!

It’s great, easy and delicious! Extremely fluffy, and useful for a beginner baker like me!

Hi!
I’m really looking forward to using this recipe along with your gluten-free cookie cake! Quick question, do you recommend salted or unsalted butter?
-
I usually use unsalted!
-
-
What is the oven temperature and length of time for a Bundt cake?
-
This recipe is for buttercream, so that will depend on which cake recipe you’re referring to!

Hi Claire! May I share that your cake is the first cake I am ever making for a celebration – buttercream and all. My son calls it the Confetti Cake. The instructions were easy to follow. I am thrilled that it turned out well and is a huge hit! Thank you for giving me the confidence to bake again. 😊
-
Thank you so much! I’m so happy to hear you enjoyed it 🙂

10 stars please!!! I can’t tell you how much I enjoyed this buttercream frosting! I frosted cupcakes (store bought Pamela’s for sake of time) and the frosting was a hit! I kept thinking “I can’t believe I made that!” The sweetness was the perfect combo with the butter and vanilla without being overly sugary. I have at least a cup+ of leftover after frosting 26 cupcakes (I popped it in a freezer bag), can’t wait to use it again!

So happy to hear that! Thank you, Mary!

Hi. I followed a link here from your dairy free birthday cake recipe. Linked you have a ‘dairy free buttercream’ apart from it brings you here.. To a gluten free frosting (isn’t buttercream generally gluten free..? ) just thought I’d let you know, so it can be corrected.

Thanks for letting me know!

Really sweet and a firm texture like cream cheese frosting.
I understand the importance of following the times and using a stand mixer. I used 5 cups of powdered sugar and 3 tablespoons of oat milk. I selected salt-free Miyokos butter, which gave it a taste slightly like cream cheese, and a similar texture to cream cheese frosting used on a red velvet cake. I sliced each cake in half to double the layers, and there was enough frosting. The assembled cake traveled well
