Homemade Rainbow Cupcakes Recipe

There's no doubt that classic cupcakes are great for any occasion. Whether you're serving them for a birthday party or an anniversary celebration, cupcakes are the ideal go-to dessert. But what if you could take a simple homemade cupcake recipe and kick it up a notch? Now you can with these incredibly colorful cupcakes.

Rainbow cupcakes are the perfect splash of color to add to any celebration. You can opt to include a full rainbow of six colors or only choose a select few. Want even more customization? Choose different hues of each color rather than your classic primary options. It's all up to your creativity.

With simple ingredients, you can bake these exciting cupcakes from scratch. Color the batter, along with the frosting, to create the ultimate rainbow display. And of course, don't forget to top them with rainbow sprinkles to make these fun and festive rainbow cupcakes that much better. 

Ready to get started on making this colorful cupcakes recipe? First, grab all of your ingredients. For this rainbow cupcakes recipe, you'll need white sugar, flour, baking powder, baking soda, salt, two eggs, oil, milk, and pure vanilla extract. For the frosting, you'll also need one stick of butter and powdered sugar. And of course, you'll need a rainbow of food coloring along with your favorite rainbow sprinkles.

Once your ingredients are gathered, you're ready to get to baking. First, preheat the oven to 350 F.

Next up, add all of the dry ingredients into a mixing bowl. Add the flour, sugar, baking soda, baking powder, and salt. Use a hand mixer to mix the dry ingredients until combined. Be sure the mixture is free of any large clumps before moving on to the next step.

With the dry ingredients mixed together, it's time to add the wet ingredients. Add in the two eggs, one at a time. Once the eggs are mixed in, add in the milk and mix. Last, mix in the oil and vanilla extract.

Mix the cake batter until just combined. Be sure not to overmix the batter so you don't end up with dry cupcakes.

Once the cupcake batter is ready, divide it into six different bowls. You'll want about half a cup of batter in each bowl. Use food coloring to dye each section of batter.

Line a cupcake pan with paper liners, and use a spoon to scoop a small amount of each color of batter into each cupcake well. It's best to start with purple and work your way to red, filling each cupcake well about halfway full.

Once prepped, bake the cupcakes for 18 minutes until the tops are set. When fully baked, remove the cupcakes from the oven and set them aside to completely cool while you make the frosting.

While the cupcakes are cooling, make the frosting. Put the softened butter into a mixing bowl. Cream the butter and add in two cups of powdered sugar. Mix the butter and sugar, add in the milk and vanilla extract, and mix again. Gradually mix in the remaining powdered sugar until the frosting forms. Once the frosting has formed, turn the speed up on the mixer to mix it until fluffy.

Once the cupcakes are fully cooled, pipe the cupcakes with white frosting. If you'd prefer rainbow frosting, add food coloring. To create a rainbow effect, divide the frosting into multiple bowls. Color each bowl of the frosting as desired. Add a spoonful of each color, alternating between, to a piping bag, and pipe the cupcakes with the rainbow frosting. Decorate the rainbow cupcakes with your favorite rainbow sprinkles to finish them off.
