Why We Love This Recipe
I think you might be surprised just how easy it is to make Funfetti Cupcakes from scratch. You might never go back to the store-bought mix again.
The entire recipe is so easy, and they taste wonderful. The sprinkles add the perfect touch of color for a festive dessert.
Ingredients

Cupcakes
- Baking Soda. You can also try one of the Best Baking Soda Substitutes.
- Vanilla extract. Pure vanilla extract is best.
- Buttermilk. This needs to be at room temperature.
- Rainbow Sprinkles. I like to use jimmies because they don’t bleed like sugar sprinkles.
Frosting
- Powdered Sugar. If the powdered sugar is lumpy, sift for best results.
You can get the entire ingredients at the bottom of the page.
Variations
- Frosting. If you love chocolate, try using chocolate frosting. We have a good recipe for chocolate icing that is great on cupcakes and cakes. Homemade Cream Cheese Frosting Recipe is also great.
- Mini Cupcakes. The batter can be used to make mini cupcakes for bite sized treats. The baking time will not take as long and should be reduced. Insert a toothpick in the center to ensure it comes out clean.
- Holidays and other occasions. This recipe can easily be used year-round for any occasion. Just change the color of the sprinkles to match the holiday or event. Red and pink would be cute for Valentine’s Day, red and green for Christmas and pastels for Easter.
How to make confetti cupcakes

Step 2. Combine the dry ingredients. Whisk together flour, baking powder, soda and salt. Set aside the flour mixture.

Step 3. Beat the eggs and sugar until fluffy.

Step 4. Gradually add the dry ingredients alternating with the buttermilk. Mix together until well combined. You can use a stand mixer or hand mixer.

Step 9. Pipe the vanilla buttercream frosting using a decorator’s bag fitted with a star tip. and top with more rainbow sprinkles. Make sure the cupcakes are completely cool before frosting.
Pro Tips
- Sprinkles. For the sprinkles, use Jimmies or Quins. Do not use nonpareils as the color will blend through the batter and won’t look as pretty. The contrast of the batter and the sprinkles is so pretty using jimmies.
- Piping Bag. It is easiest to pipe the frosting using a piping bag and star tip. However, you can also use a ziploc bag if you don’t have one.
Simply cut the corner off and insert the star tip. Add the frosting and decorate as normal. - Gently fold in the sprinkles. Carefully fold in the sprinkles to the batter. You do not want to deflate the light and fluffy batter that you just made.
- Reduce the recipe. This makes 24 cupcakes. If you only need 12 cupcakes, feel free to reduce the recipe or you can freeze the extra.
Storage
Store the leftover cupcakes in an airtight container at room temperature for 3-4 days or you can place them in the refrigerator up to 1 week.
I have a cupcake carrier that is so handy for storing the cupcakes. It keeps them fresh and the icing stays intact. This is also a great option to easily transport the cupcakes to parties, events and other gatherings.
Can you freeze cupcakes?
The cupcakes can be frozen if you need them to last longer or to make in advance. You can freeze them unfrosted or frosted.
I recommend freezing them without the icing because it is easier. Place the cupcakes inside a freezer container and freeze up to 3 months. Thaw in the fridge overnight when ready to use and decorate as normal.
If you freeze the cupcakes with icing, it is best to flash freeze them on a baking sheet for 1 to 2 hours. This will harden the frosting so it does not get messed up in the container.
