Ingredients
NOTE: We are working on a regular gluten-containing version of this cake for those that aren't gluten free. We'll add it into the recipe as soon as we perfect it!
As we mentioned, this cake is both vegan and gluten free. That means there are a few slightly unusual ingredients, like applesauce, which helps add moisture to the cake since it contains no eggs.
First things first, you'll want to bring a few of the ingredients (vegan butter, applesauce, creamer/milk and lemon) to room temperature before mixing. This cake contains vegan butter, which when mixed with colder ingredients tends to seize up and separate.
This cake makes 3 layers, so line 3 8-inch cake pans with parchment paper and lightly oil the sides.
In a large mixing bowl, stir together gluten free all purpose flour, oat flour, baking powder, baking soda and salt. Look for a gluten free all purpose flour that contains xanthan gum, as this well improve the texture of your cake.
Oat flour prevents the cake from having a gummy texture that sometimes occurs with gluten free flour mix.
In a stand mixer, cream butter for a few minutes until light and fluffy. Add in sugar and vanilla and continue mixing until incorporated. Add in about quarter of the dry mixture until incorporated. Add another quarter, mix well, then add in applesauce.
Add in remaining flour and mix. Stir in lemon juice and vegan creamer and mix just until the batter comes together. Gently fold in the sprinkles, transfer to cake pans and bake right away.
Baking tip: lemon juice and baking soda create a chemical reaction that helps vegan baked goods rise. Since it happens pretty quickly, it's best to get your cakes baking right away so the reaction happens in the oven!
Vegan frosting
This buttery, rich vegan vanilla buttercream is quite easy to whip up. It's the perfect complement to this fluffy funfetti cake!
Make sure your vegan butter is softened at room temperature before making the frosting. We also use a touch of vegan cream cheese for a bit of tang, so bring that to room temperature as well. (If you'd prefer to use just vegan butter, that's perfectly fine, too).
Whip the butter and cream cheese until light and fluffy, then slowly add in powdered sugar, along with vanilla extract and a pinch of salt. You may or may not need a tablespoon or two of almond milk to thin it out. I didn't, but feel free to if it needs it.
Tip: for extra smooth frosting, sift the powdered sugar before mixing.
Let it whip up on medium speed for a few minutes until light, fluffy and delicious! If your kitchen is particularly hot/humid, you may want to refrigerate the frosting while you're waiting for the cake to cool.
Decorating tips
First and foremost, be sure to let the cakes cool COMPLETELY before attempting to frost. If they're not completely cool, the frosting will melt and you'll end up with uneven, messy layers.
Once the cakes cool to the touch, you may want to cool further in the fridge for an hour or so before frosting if you have time. As a general rule of thumb, you should try to wait at least an hour and a half before frosting for best results.
To make the cakes more even, we suggest using a sharp knife to cut off the slight rounded top of the cake. Carefully trim until the top layer is even and flat, then generously frost. Repeat with the second and third layer.
It's important to keep the frosting relatively cool. If it's a hot/humid day, you may want to refrigerate the cake and/or frosting for a little while before frosting the sides.
Apply frosting generously to all sides, then use a flat angled spatula or a multi-purpose flat scraper to smooth out the frosting. You can keep it smooth or use decorating tips for extra flair.
To apply sprinkles to the sides of the cake, place them in the palm of your hand and gently apply. You'll probably make a bit of a mess as some of the sprinkles won't make it on the cake. Scoop them up and reuse for the next handful.

Hi! Is butter in the cake necessary? Have you tried without?
Bess says
Thank you for the recipe! It all came together so well. I actually accidentally used regular flour the first time, and it all worked out fine! Just needed a shorter baking time. Tasted very good.
BUT with gluten-free flour this is truly an amazing recipe, moist cake and fluffy. The icing took a while to come together, and we had to keep it chilled, but that may be because our vegan butter was mainly oil so it would melt easily. Regardless, so delicious and my vegan friends loved it. Thank you!
Hayley says
If I make the cake the night before and frost it in the morning, will it be ok?
Brent Harrison says
Sorry for the delayed reply - hopefully the cake turned out OK if you've made it already. You should be totally fine baking the night before and frosting the next day.
Irene says
For the oat flour, can I just blend oats in the blender until it becomes a powder?
Lexi says
Hi! Yes, you can check out this post for more details on how to make it from scratch: https://cookieandkate.com/how-to-make-oat-flour/
Tina says
This looks amazing for my sons birthday! If I wanted to make a sheet cake, do you think halving the recipe would work?
Lexi says
Yes, that should work!
Dani says
would the 1x recipe make 12 cupcakes?
Lexi says
Hi Dani, I actually think it would make a few dozen (maybe 3-4 dozen) cupcakes! Since it's a 3 layer cake, it's quite a large quantity of batter.
