When it comes to bright and colorful this Rainbow Lollipop Drip Cake is at the top of our list for super fun cakes to make for any occasion! This fantastic cake is so fun to make and looks so amazing, yet it is easy enough for anyone to DIY at home!
Change up your colors if you like, but we love the vibrant rainbow royal icing dripping off the edges of our candy-topped drip cake!
Our rainbow drip cake consists of four six inch round white cakes layered with vanilla buttercream frosting as the filling and as the smoothed icing on the entire cake. We piped a bottom border of buttercream as well, then sprinkled it with crushed lollipops. Once these basics are done, you're ready to make your royal icing and create your own spectacular drip cake!
We made our royal icing batch using meringue powder (the alternate listed below in the recipe), then divided the icing into six batches that were separated into small ziploc bags. To ensure that we didn't change the consistency of the royal icing, we used gel food coloring to color our divided royal icing portions.
Snip the edges of your ziploc bags after coloring the royal icing, then start adding the colors to the center of the top of the cake. Work your way toward the edges, then combine the colors by running a toothpick through the royal icing (see video below). When you are using your toothpick, replace with a clean one as necessary to keep the colors just combined (but not muddied together).
Top your cake off with your favorite assortment of rainbow lollipops and allow the royal icing to dry, as it will set in place in about 12 hours. Enjoy!
Rainbow Lollipop Drip Cake
Royal Icing for Drip Cakes
- 1 large egg white
- lemon juice (from ½ large lemon)
- 2 cups confectioners sugar
- 2 tablespoon milk
- 6 gel food colors
Assembling the Rainbow Lollipop Drip Cake
- You can stack your cake as high as you like, but we baked 4 - 6 inch rounds and filled the layers with vanilla buttercream frosting. We then applied a thin crumb coat to the layered cake (used to prevent crumbs from showing through your frosting) and refrigerated the layered and coated cake for about 30 minutes, or until you are ready to move onto the next step.
- Frost your cake with another batch of vanilla buttercream frosting, smoothing the frosting on all sides and making the top of the cake as smooth and level as possible. Apply a bottom border of piped buttercream frosting (if desired) and sprinkle crushed lollipop candy on the bottom border.
Royal Icing for Drip Cakes
- *You can also use meringue powder instead of egg white with lemon (we use 2 teaspoon meringue powder + 2 tablespoon water).
- Beat the egg white (or meringue powder with water) with the whisk attachment of your stand mixer or using a hand mixer until foamy. Start on slow speed when mixing the powder until it is combined with the water, then increase the speed to medium-high.
- Add lemon juice and mix briefly, then add the confectioners sugar and mix at a slow setting until combined. Drizzle the milk in, adding small amounts until you have the desired consistency for your royal icing.
- The royal icing should cling to your spoon and slowly run off, not pour off quickly, so that the drip effect will work correctly.
Apply Royal Icing for Drip Cake Effect
- Divide your batch of royal icing into 6 equal portions, placing each portion into a separate ziploc bag. Add desired gel food coloring to each bag (gel food coloring will not change the consistency of your royal icing, the drops of food coloring can make your icing more runny).
- Move the royal icing and food coloring around in the bag until well combined, repeat with each color.
- Snip a small corner off of each of your bags of royal icing and start applying the icing at the center of the cake, randomly placing the colors on the top of the cake. Work outward toward the cake edge until you have enough royal icing on the top of the cake to start combining the colors and push your icing toward the edges to begin the 'drip' effect.
- Use a toothpick to combine the royal icing colors, you can swirl your colors together or drag the toothpick in opposite directions. Either way, work your royal icing toward the top edge of the cake to allow it to slowly drip down the sides. Replace your toothpick(s) as needed to keep your colors clean when combining.
- Once you have your colors combined and your drip effect started down the sides of your cake, top your cake with rainbow lollipops and then allow the royal icing to set in place (about 12 hours).
