I wrote this recipe for Ryze and was compensated for developing it. Because I loved the recipe, I wanted to also share it with you here. As always, all opinions are entirely my own. Thank you for supporting Flippin’ Delicious™ and the companies I work with.
There is something magical about biting into an allergy friendly rainbow cupcake. This particular cupcake is gluten free and dairy free, so everyone in my family could enjoy it. The cupcakes rise into perfectly smooth domes, it has a tight, yet tender crumb, and is topped with a perfectly fluffy vanilla bean frosting.
The rainbow colors stay bright and vibrant, creating a very colorful blank canvas.
Whether you decorate these cupcakes to be the rainbow and pot o’ gold in one, make them into whimsical unicorns, or simply top them off with a swirl of fluffy frosting, they are sure to take the center stage.
I have a pretty strong feeling that I’ll be making these gluten free rainbow cupcakes again…and again. Nothing makes a better celebration cupcake!
If you want a stunning layer cake, you have to try my gluten free rainbow cake. 4 rainbow cake layers (or 6 if you bake the cake using a 6 inch round pan instead of a 9 inch round pan.) I’ve made that cake with and without the pinata effect, and it is a fan favorite both ways. I actually adapted my gluten free rainbow layer cake recipe to make these gluten free rainbow cupcakes.
I made these dairy free rainbow cupcakes for a party at work, and they were a huge hit. Did I mention my day job is in the corporate office of a pizza company? Everyone there eats gluten with a side of extra gluten. If that doesn’t demonstrate how bomb-diggity these gluten free rainbow cupcakes are, I don’t know what will.
I’ve been experimenting with a new-to-me Gluten-Free Flour, Ryze. (You’ll find my Gluten Free Red Velvet Brownies on their website.) What is special about Ryze is that is is just rice flour.
I know, when I say “rice flour” you immediately think of cupcakes that taste like “grit” and “sand,” but that isn’t the case with Ryze. It has different grinds of rice flour, that mimic regular wheat flour.
They have 2 different flour blends, a blue bag for recipes that need more structure or “chew” like cookies and bread and a yellow bag that is perfect for donuts and cakes (which is what I used in this recipe.)
I heard about Ryze from my good friend Chrystal from Gluten-Free Palate. She is the donut queen and recently wrote several Gluten Free Donut recipes in an article (and COVER RECIPE!!!, I am a very proud friend) for Gluten-Free and More Magazine (formerly Living Without.) I visited Chrystal last October and she baked me her phenomenal Gluten Free Cinnamon Sugar Donuts using Ryze’s yellow bag. After one perfect bite, followed by the rest of the donut, I was excited to try Ryze’s flour for myself. I used Ryze’s yellow bag in this recipe and was very happy with the results. If you don’t have Ryze flour, you may use my gluten free cake/cookie flour blend, and add 1/4 teaspoon of xanthan gum to your recipe.
- 2 cups white sugar
- 1 cup oil
- 4 eggs
- 3 ¾ cupRYZE Yellow Flour Blend
- ¾ teaspoon baking soda
- ½ teaspoon salt
- 1 ½ cups buttermilk (or 1 ½ cups of your favorite dairy-free milk mixed with 1 ½ tablespoons of white vinegar)
- Food coloring, as desired
- 1 cup palm shortening
- ½ cup vegan butter
- 4 cups powdered sugar
- 1 teaspoon vanilla extract
- 2 teaspoons vanilla paste
- 1-2 tablespoons dairy-free milk
- Preheat the oven to 350°F and line your cupcake pans with cupcake liners.
- Using a stand mixer, or electric beaters and a bowl, beat the sugar and oil together until well combined. Add the eggs one at a time, beating until completely incorporated before adding the next. Whip until very smooth and slightly fluffy.
- In another bowl, whisk together the RYZE Yellow Flour Blend, baking soda, and salt.
- Add approximately ⅓ of the flour mixture to the sugar/oil/egg mixture and mix until incorporated. Beat in half of the buttermilk, and mix until smooth. Follow that with another ⅓ of the flour mixture, mix until smooth. Then the rest of the buttermilk, mix until smooth. Finally add the rest of the flour mixture, and mix until smooth.
- Divide the batter evenly between 6 small bowls. Add food coloring to each bowl to create the colors desired for your rainbow cupcakes (for these cupcakes purple, blue, green, yellow, orange, and red were used.)
- Evenly divide the brightly-colored batter between the prepared cupcake pans. You may do this with a small spoon, or for easier clean-up transfer each color to a sandwich-sized plastic zipper bag. Starting with the first color, cut off one of the corners, then squeeze a small amount of batter into each cupcake liner. To create the cupcakes as pictured, start with purple, then blue, then green, then yellow, then orange, and finally red.
- Using a toothpick, gently swirl the batter in each cupcake to create a marbled effect.
- Bake for 25-30 minutes, or until a toothpick inserted near the center of a cupcake comes out clean.
- Cool before frosting and decorating.
- Using a stand mixer, or electric beaters, whip the palm shortening and vegan butter until very smooth, light, and fluffy (about 5 minutes.)
- Add the powdered sugar, and beat until combined. Add the vanilla extract and paste and mix until evenly combined. The frosting will not be smooth. Add non-dairy milk one TEASPOON at a time, beating well after each addition, until you have a smooth and creamy frosting. Add up to 2 tablespoons of milk. (we used about 1 ½ tablespoons.) Be very careful to not add too much milk as that may cause your frosting to separate. If that does happen, add another ¼- ½ cup of powdered sugar and beat until the frosting comes back together.
- Frost the cupcakes as desired, and decorate with sprinkles, shamrock coins, or chocolate shamrocks. To make your own green chocolate shamrocks melt ½ cup of green candy melts according to their package directions and pipe them onto parchment paper. A sandwich bag with a tiny bit of a corner snipped off makes an easy, disposable, piping bag.
