Ingredients

  • 2 baked 8 or 9-inch white cake layers
  • 1 (3 oz.) package Jell-O (any flavor)
  • 1 cup boiling water
  • 1/2 cup cold water

Instructions

  1. Place the cooled white cake layers, top side up, in 2 clean layer pans.
  2. Prick each cake with a fork at 1/2-inch intervals.
  3. Dissolve the Jell-O in boiling water.
  4. Add cold water to the dissolved Jell-O.
  5. Pour the Jell-O mixture carefully over the cakes.
  6. Chill for 3 to 4 hours.

Tips & Substitutions

For vibrant colors, use different flavors of Jell-O that complement each other. If you want a lighter option, consider using sugar-free Jell-O. Ensure the cake layers are completely cooled before adding the Jell-O mixture to prevent it from sinking. You can also experiment with different cake bases, such as a gluten-free option, to cater to various dietary preferences.

Serving Suggestions

This Rainbow Cake is a delightful centerpiece for celebrations and pairs beautifully with a Fat-Free Fruit Smoothie for a refreshing treat. Consider serving it with whipped cream or a scoop of vanilla ice cream to enhance the flavors. It also complements fresh fruit salads or light desserts for a well-rounded meal.

Storage & Reheating

Store leftover Rainbow Cake in an airtight container in the refrigerator for up to 3 days. To maintain the cake's moisture and flavor, avoid freezing it, as the Jell-O can become watery upon thawing. To serve, simply slice cold from the fridge; no reheating is necessary, preserving the refreshing taste.

Frequently Asked Questions

Can I use a different type of cake instead of white cake?

Yes, you can use any flavor of cake you prefer! A chocolate or vanilla cake can work well, but keep in mind that the Jell-O colors will show more vibrantly on lighter cakes. Experiment with flavors to create your own unique Rainbow Cake.

How can I make the Jell-O soak into the cake better?

To help the Jell-O soak evenly, make sure to prick the cake layers thoroughly with a fork. You can also let the Jell-O mixture cool slightly before pouring it over the cake to prevent it from being too hot, which can break down the cake structure.

Can I make this cake in advance?

Absolutely! You can prepare the Rainbow Cake a day ahead. Just ensure it is tightly covered in the fridge after chilling. This allows the flavors to meld beautifully, making it a great option for parties or gatherings.
