- 1¼ cup water
- ⅓ cup vegetable oil (or substitute with melted coconut oil)
- 3 large eggs
- Frosting:
- 1 cup butter, softened (unsalted preferred)
- 4½ cups powdered sugar (sifted for smoother frosting)
- 1 teaspoon vanilla extract
- ⅓ cup heavy cream (or substitute with whole milk for a lighter texture)
- ¼ teaspoon salt
- 4 drops green food coloring (adjust for desired shade)
- Toppings:
- 12 AirHeads Extreme Rainbow candies (cut in half for rainbow arches)
- 3 cups mini marshmallows (for cloud accents)
- 24 Rolo candies (for pots of gold)
- Gold sprinkles (for decorating)
Step-by-Step Instructions
- Prepare the Cupcakes:
- Preheat your oven to the temperature specified on the cake mix package (usually 350°F/175°C).
- In a large bowl, combine the cake mix, water, vegetable oil, and eggs. Mix until smooth and well combined.
- Line a muffin tin with cupcake liners and fill each about ⅔ full with batter.
- Bake for 14-19 minutes, or until a toothpick inserted into the center comes out clean.
- Let the cupcakes cool completely on a wire rack before frosting.
- Make the Frosting:
- In a large mixing bowl, beat the softened butter until creamy and smooth.
- Gradually add the powdered sugar, vanilla extract, heavy cream, and salt. Mix with a hand mixer on medium speed until light and fluffy.
- Add green food coloring, one drop at a time, until you achieve your desired shade of green.
- Assemble the Cupcakes:
- Spread or pipe the green frosting onto each cooled cupcake.
- Cut each AirHeads Extreme Rainbow candy in half and place them on top of the cupcakes to create rainbow arches.
- Place two mini marshmallows at each end of the rainbow to resemble clouds.
- For the pot of gold, pipe a small amount of frosting onto the wide end of each Rolo candy, then press into gold sprinkles to coat. Place one Rolo at the base of each rainbow.
- Serve and Enjoy:
- Arrange the cupcakes on a platter and serve immediately, or store in an airtight container for up to 2 days.
Rainbow & Gold Topping Ideas
Get creative with your cupcake toppings! Instead of AirHeads Extreme candy, try using _sour ribbons_ or _fruit roll-ups_ for the rainbow. For the pot of gold, swap Rolos with _chocolate coins_ or _mini Reese’s cups_ dipped in gold sprinkles. You can even add _edible glitter_ to the frosting for extra sparkle!
Time-Saving Tips for Busy Bakers
Short on time? Use pre-made frosting and simply tint it green with food coloring. Opt for _ready-to-use cupcake liners_ and _disposable piping bags_ to cut down on cleanup. You can also bake the cupcakes and prep the toppings a day ahead, then assemble them just before serving.
Storage & Serving Suggestions
Store these festive cupcakes in an _airtight container_ at room temperature for up to 2 days. If frosted, they’ll stay fresh in the fridge for 3-4 days. Bring them to room temperature before serving for the best texture. Pair them with a glass of milk or a cup of coffee for a delightful treat!
Fun Recipe Variations
Want to mix it up? Try using _chocolate cake mix_ for a richer base or _lemon frosting_ for a tangy twist. You can also create a “cloud effect” by adding a small dollop of whipped cream under the rainbow. For a kid-friendly version, use _gluten-free cake mix_ and _vegan butter_ in the frosting.
Essential Equipment Guidance
For perfectly frosted cupcakes, a _piping bag with a star tip_ works wonders. If you don’t have one, a _ziplock bag with the corner snipped off_ is a great alternative. Use a _muffin tin with cupcake liners_ for even baking and easy removal. A _hand mixer_ will make your frosting light and fluffy in minutes!
