Best Sprinkles for Confetti Cupcakes

What makes the colorful "confetti" in confetti cupcakes? Sprinkles!

Rainbow jimmies are the key to making funfetti-style cupcakes.

The ones I used in this recipe are these dye-free rainbow softies by Supernatural. They still have brilliant colors without extra food coloring.

If you have leftover sprinkles, make Birthday Cake Waffles!

Substitutions and Variations

To make these cupcakes gluten free, you can use a gluten-free 1:1 flour substitute, such as King Arthur Measure for Measure Flour.

Sour cream is my secret ingredient for moist cupcakes, but you can substitute it for greek yogurt.

Colorful sprinkles are what make these cupcakes so fun! If you're sensitive to food dye, try out these rainbow sprinkles that contain no artificial dyes.

I typically use whole milk in this recipe, but you can use 2% milk or a dairy alternative if you prefer.

Tips for Success

Let the butter and eggs come to room temperature before mixing. They'll mix easier and more evenly throughout the batter.

Don't over mix the batter. Mix until the ingredients come together well and then turn off the mixer.

Add the flour mixture into the wet ingredients slowly so that it can mix evenly!

How to Store Leftover Confetti Cupcakes

Store confetti cupcakes in an airtight container in the refrigerator for up to five days. You can also store them at room temperature, they just won't last as long.

If you want to save some time, make the cupcakes ahead of time and store unfrosted cupcakes in an airtight container. (You can use my tutorial for storing muffins for some tips on keeping them from getting soggy or dried out.)

Then make the creamy vanilla buttercream the next day and ice them just before serving!

FAQ

What is the secret to super moist cupcakes?

Using sour cream or greek yogurt in your cupcake batter will always help them retain moisture! It is also helpful to mix your batter on low speed and to be cautious of over mixing the batter.

Will sprinkles bleed into buttercream frosting?

Over time, the dye from sprinkles will bleed into buttercream frosting. To ensure this doesn't happen, add extra sprinkles onto the top of your confetti sprinkle cupcakes right before you serve them. If you plan to store them before serving, wait and add the sprinkles once you remove them from the fridge.
