- ½ tsp baking soda: Aids in leavening. Double-check the expiration date.
- 1 tsp kosher salt: Balances sweetness and enhances flavors.
- 1 ⅓ cups buttermilk, at room temperature: Contributes to a tender texture. Substitute with milk plus a splash of vinegar if needed.

- 4 ½-5 cups powdered sugar: Sweetens the frosting. Adjust the amount for your desired sweetness.
- ⅓-½ cup heavy cream: Makes the frosting light and fluffy. Ensure it’s heavy cream for stability.
- Red, green, and yellow gel dyes: Perfect for adding color to your frosting.
How to Make Rainbow Funfetti Cupcakes
- Preheat the Oven: Set your oven to 350°F (175°C) and prepare two 12-cup muffin tins with parchment liners to ensure easy removal.
- Mix the Wet Ingredients: In a large bowl, beat together 1 cup vegetable oil and 1 ½ cups sugar for 2-3 minutes until well-combined. Whip in the 3 large eggs, one at a time, followed by 2 tsp vanilla extract and ½ cup plain whole milk Greek yogurt.
- Combine Dry Ingredients: Gradually add in 2 ½ cups all-purpose flour, 1 ½ tsp baking powder, ½ tsp baking soda, and 1 tsp kosher salt to the mixture. With the mixer running, stream in 1 ⅓ cups buttermilk until just combined—be careful not to overmix. Gently fold in ½ cup funfetti jimmies.
- Fill the Muffin Tins: Spoon batter into each cupcake liner, filling them about ⅔ full. This typically yields 22-24 cupcakes. Bake in the oven for 25-30 minutes. They’re done when a toothpick inserted comes out with a few moist crumbs attached. Let them cool in the pans for about 10 minutes before transferring to wire racks to cool completely.
- Make the Frosting: Whip together 1 stick of softened butter and 1 tsp vanilla extract until combined. Gradually add in 4 ½ cups of powdered sugar and ⅓ cup heavy cream. Beat on high until fluffy, about 2-3 minutes. If needed, add an extra tablespoon or two of cream to reach your desired consistency. Remember to scrape down the sides for even mixing!
- Color the Frosting: Divide the frosting into three bowls—color one with 2-3 drops of red dye, the second with green, and the last with 4-5 drops of yellow dye. Stir until evenly mixed.
- Pipe the Frosting: Alternate spoonfuls of each colored frosting into a piping bag. Pipe onto cooled cupcakes to create a beautiful swirl of colors. Finally, top each cupcake with additional funfetti for that celebratory touch.
Storing & Reheating
Store your cupcakes at room temperature in an airtight container for up to 3 days. If you need to refrigerate them, place them in a sealed container for up to a week. You can also freeze the cupcakes in a single layer for up to 3 months. To reheat, microwave for about 10-15 seconds until warm, but be aware that the frosting might lose some texture. A light whip of the frosting can help refresh the look.
Chef’s Helpful Tips
- Avoid overmixing the batter, as this can lead to dense cupcakes.
- Always bring your eggs and buttermilk to room temperature for a smoother batter.
- To ensure even baking, rotate your cupcake pans halfway through baking.
- If your frosting is too thick, a tablespoon of heavy cream will often do the trick to lighten it up.
- For extra fun, add more funfetti jimmies to the batter for a colorful surprise!
The irresistible charm of Rainbow Funfetti Cupcakes lies not only in their appearance but also in their delightful flavor. Baking these colorful treats allows you to tap into your creativity, mixing colors and flavors to brighten up any day. Experiment with different colors or even add some flavoring to the batter for a twist. Enjoy your baking adventure!
