This is a totally delicious cooked frosting recipe for Gluten-Free and Corn Free Frosting with a Dairy Free option – make it with butter or with a non-dairy butter substitute. Either way, it’s totally yum – think pillowy clouds of marshmallow goodness.

– Updated May 2021 –

I’ve included a vanilla and a chocolate version – I’ve been known to throw in a little espresso powder in the chocolate version for a mocha/dark chocolate kick.

Freeze dried strawberry powder does fabulous things to the vanilla option, but you’ve gotta be the kind of person who has freeze-dried fruit powder in your pantry to begin with. I’m that kind of person, and I know it makes me odd. But whatever. Top this frosting with sprinkles, fruit, or just make fun, fluffy swirls.

For fluffy + delicious results:

Use finely ground sweet or white rice flour (my favorite is from Koda Farms, I use it for everything.) Brown rice flour won’t work well here, and a gritty grind with make grainy icing. 

Since most powdered sugar has corn, the rice flour acts as the binder here. The finished texture of this frosting is actually smoother and has a better mouthfeel than traditional “easy” buttercream made with powdered sugar.

Flavor it up: chocolate or vanilla!

Try vanilla bean paste if you haven’t already – it’s got vanilla extract and vanilla bean specks combined, and it will help take all your baked goods to the next level. It can be used 1 for 1 for vanilla extract in all recipes, and it’s a game-changer. It adds a big punch of vanilla flavor to this frosting.

If you’re making chocolate frosting, I like Dutch-processed cocoa, which is also called Dutched-chocolate. It gives a richer chocolate flavor than standard cocoa powder, and certainly better than raw cacao, which isn’t roasted. I prefer Droste dutch-processed cocoa, it’s my go-to. You can also add a pinch of espresso powder to get a deeper dark chocolate taste.

This gluten-free, dairy-free, corn free frosting is perfect for icing cakes and cupcakes, but it’s not stiff enough for fancy decorating. So give it a few lovely swirls with a spatula and call it good. And it is good.

Recipe frosts 12 cupcakes liberally or a 9×13 sheet cake. Now you’re ready to make cookie sandwiches, party cakes, or attempt and dairy-free version of my friend Kyra’s Red, White & Blueberry Cake Roll.
