How to make rainbow cupcakes?
- Prepare cake batter– By mixing together eggs, butter, milk, water, cake mix.
- Divide batter– Into 6 separate bowls.
- Color batter– Use a different color in each bowl.
- Fill liners– Halfway full is best.
- Bake– Until an inserted toothpick in the center comes out clean.
- Cool– Until they are room temperature.
- Ice cupcakes– With whipped cream.
- Enjoy– Toss on some sprinkles and enjoy!
Rainbow icing cupcakes
Since the cupcakes are already so vibrant, I paired it with white whipped cream and decorated with colored sprinkles. The white icing really makes the cupcake colors pop! Another white icing option is White Chocolate Buttercream Frosting or this classic American Buttercream Frosting.
How to make rainbow frosting? Divide the buttercream into six small bowls, add a different color in each bowl. Then, take a sheet of saran wrap and spread each colored butter cream in a straight line next to each other. Next, roll the saran wrap and place it into a piping bag with a large star tip (Tip 1M) and pipe a swirl on top of each cupcake.
Filing ideas
Similar to these Birthday Cupcakes (Pinata Cupcakes), fill today’s treats with sprinkles too. It’s a fun surprise as you take your first bite.
You can also fill with jams or preserves, frostings, pie fillings, caramel sauce, dulce de leche, peanut butter, Nutella, ganache.
You can also fill them with truffles. Try these Chocolate Chip Cookie Dough Truffles or these Chocolate Truffles.
Variations for colorful cupcakes
Rainbow unicorn cupcakes– Frost cupcakes in multi colored frosting. Then, decorated with a fondant golden horn, eyes and lips
Rainbow cupcake cake/ Pull apart cake- Group all the cupcakes together into a semi circle and frost rows of individual colors on top. Place lots of marshmallows on both ends to represent clouds. They are fun to serve at birthday parties, just likes these Pull Apart Watermelon Cupcakes and these Football Pull Apart Cupcakes.
Make a cake tower- Stack all the iced cupcakes on top of another in a pyramid formation, similar to this Mother’s Day Cake Tower.
Add cupcake toppers– Such as cute cardboard cut outs or decorative toys, small candles or even small candies.
Use pastel colors– Add less food coloring or use pastel food colors for lighter colored cupcakes. These are perfect for Easter parties.
Tips and Techniques
How to color batter? Use liquid food coloring or gel food colors.
Gel colors vs. Liquid food coloring– Either can be used. Gel food coloring is more concentrated than liquid food coloring. It gives a more vibrant color and you don’t need to use a large quantity. There is also a variety of shades to choose from.
Do not frost warm cupcakes- Because this will cause the frosting to melt and create a huge sticky mess. Let the cupcakes cool completely before piping.
Can you freeze cupcakes with icing? No. Whipped cream is made with dairy and does not thaw well. You can freeze unfrosted cupcakes and then ice them upon thawing.
Cake mix vs. Scratch recipe– Using cake mix is easy and convenient. However, you can use a scratch recipe, if you like. It will take a little more time. Try these soft and fluffy Vanilla Cupcakes. Divide the batter and color it and then, bake.
Why did my cupcakes turn brown? They have been baked for too long. When cupcakes are over-baked, the tops become brown and hard.
How to know cupcakes are done? Insert a toothpick in the center and if it comes out clean, they are ready.
Make a bigger batch- Just double all the ingredients and this will be perfect for a big party.
Storage
Refrigerate- In a sealed container for up to 3-5 days.
Freeze- Unfrosted cupcakes can be frozen in a sealed container for up to 1 month. When you are ready to enjoy them, let them thaw in the fridge overnight or allow them to thaw at room temperature for 40 minutes. Then, pipe icing and decorate with sprinkles.
Another idea
Another approach to these colorful cupcakes is to decorate with fondant, as seen below. The flowers were made with Homemade Marshmallow Fondant. They cupcakes were frosted in Chocolate Buttercream Frosting. There is also video tutorial so that you can follow along. Prepare to be surprised by this super easy cake decorating technique!
