Experience the enchantment of the French dessert “Île flottante” with a whimsical and colorful twist in this Rainbow Floating Island recipe. This delightful dessert pairs silky-smooth blue custard with vibrantly colored meringue islands, creating a visually striking dish that’s perfect for adding a touch of magic to any dining occasion.


  • Eggs: 6, separated
  • Sugar: 2/3 cup
  • Milk: 2 cups
  • Vanilla Pod: 8 3/4 ounces, seeds scraped
  • Food Coloring: 3 tablespoons blue, 1 tablespoon each of green, yellow, and red
  • Multicolored Candies: for garnish


  1. Prepare the Custard Base: In a large mixing bowl, whisk together the egg yolks and sugar until the mixture is light and fluffy. Gradually mix in the milk and the seeds scraped from the vanilla pod. Add blue food coloring to achieve a rich, ocean-like hue. Transfer this mixture to a saucepan and cook over medium heat, stirring continuously, until the custard thickens enough to coat the back of a spoon. Remove from heat and let cool.
  2. Make Meringue Islands: In a clean, dry bowl, beat the egg whites with a little sugar until stiff peaks form. This creates the fluffy base for your islands. Carefully spoon the meringue into silicone molds designed for small cakes or desserts. Using a small brush, gently dab the tops of the meringue with green, yellow, and red food coloring to create a rainbow effect.
  3. Microwave the Meringues: Place the meringue-filled molds in the microwave and cook on high for 1 minute and 30 seconds. This quick cook method sets the meringue into firm islands.
  4. Assemble and Serve: To serve, spoon some of the chilled blue custard into a shallow bowl. Carefully unmold a meringue island and place it in the center of the custard. The meringue should float, creating the appearance of a colorful island adrift on a blue sea. Garnish with multicolored candies for an extra touch of fun and festivity.

Preparation Tips

  • Color Intensity: For more vibrant meringues, add food coloring gradually until you achieve the desired intensity. Be careful not to overmix, as this can deflate the meringue.
  • Serving Suggestion: Serve the dessert immediately after assembly to ensure the meringues maintain their light, airy texture atop the custard.
  • Visual Appeal: Choose a clear or lightly colored bowl for serving to highlight the stunning blue custard and rainbow meringue islands.
