Vegan vanilla funfetti cupcakes with rainbow sprinkles on the side.

I don’t think I could possibly love a cupcake any more than these. These were originally going to be just plain vegan vanilla cupcakes (which would still be great tbh), but I just thought we could all use a little more joy in our lives right now so I decided to throw sprinkles all over them!

Funfetti cupcakes (and honestly cupcakes in general) are usually a dessert reserved for special occasions, but I’m here to tell you it’s ok (and even encouraged) to eat these at 11 am on a Tuesday. Or any day at any time. Because these are SO good.

They’re moist, fluffy, spongey, filled with rainbow sprinkles and smothered with an undetectably dairy free buttercream.

These cupcakes aren’t gluten free, so let me just make a really long story short to explain! I was diagnosed with Celiac Disease this year and had to undergo a “gluten challenge” to ensure accurate test results. Basically, I had to eat a lot of gluten.

While doing so, I developed this vegan cupcake recipe and they were way too good not to share, so here we are with a non-gluten free recipe! It’ll be the only one of its kind on the blog, but they were too good to keep to myself. Even though I can literally never eat them again, ugh.

How to make this recipe

This recipe comes together very easily and all in one bowl! The first step is to whisk together the oil, milk, sugar, vanilla and vinegar in a large mixing bowl.

Add in the all purpose flour (spoon and level to measure), cornstarch, baking powder, baking soda and salt. Add the baking powder/soda on top of the flour, then gently mix into the flour to evenly distribute.

This keeps this a one bowl recipe, but ensures the leavening agents are properly spread throughout the batter so the cupcakes rise evenly!

Whisk together until smooth, but don’t worry if there are a few clumps because you don’t want to over-mix the batter. It should have a pancake batter consistency, definitely not really runny, but also not so thick that its hard to stir.

Fold in the sprinkles carefully and just until combined because they will start to bleed into the batter if mixed too much. If they do bleed, don’t worry, it won’t change the flavor at all!

Spoon the batter into a lined cupcake tray, filling about 3/4 of the way up.

Bake for 18-22 minutes or until a toothpick comes out clean.

Let cool in the cupcake tray for about 20 minutes, then carefully remove. I like to gently spin the cupcakes around in the tray so any stuck parts come loose, then tilt the tray on its side slightly to slide them right out. This prevents the tops from getting smushed when you pull them out.

Wait until the cupcakes are completely cool to frost. Patience is important here (but annoying, I know) because if the cupcakes are at all warm while you frost them, the buttercream will just melt right off and it won’t be very appetizing!

To frost the cupcakes like these photos, take a long flat spatula and add a generous dollop of buttercream to the top of the cupcakes. Carefully spread it out around the cupcake, keeping an even thickness throughout.

Clean the knife off, then take the edge and run it along the side and top of the frosting to gently smooth it out. Finally, take the back of a spoon and make a small dip in the middle of the buttercream (but not all the way through to the cake), gently pushing the excess toward the sides. Fill the dip with sprinkles of your choice!

Frequently asked questions

What kind of butter do you use? For the buttercream, I find that the Earth Balance brand sticks work best. I have tested it with Miyokos butter sticks, but it melts faster than the Earth Balance. Whichever brand you use, I recommend sticks and not tubs of butter.

Do they keep? Once the cupcakes are cool, store them in an air tight container so they don’t dry out. Once prepared, they should keep for about 5 days.

Why do you need cornstarch? The cornstarch is a key ingredient to help bind everything together in these vegan cupcakes since there is no egg in this recipe. The gluten from the flour does that too, but the cornstarch also yields a really soft and tender cupcake.

Does the frosting keep? This buttercream will keep in the fridge for about a week, but it will thicken since the butter will harden, so let it come to room temperature before using it again.

Can I make them gluten free? I don’t recommend it. Instead, I would make my vegan and gluten free vanilla cupcakes instead!
