Divide & Color Batter – Divide the batter into six bowls and color each with gel food coloring.
Layer the Colors – Spoon a small amount of each color into each cupcake liner, layering in rainbow order.

Enjoy! – These magical Gold-Filled Rainbow Cupcakes are ready to shine!
- Use Gel Food Coloring for Vibrant Layers – Gel food coloring gives a more intense color without thinning the batter. Avoid liquid food coloring as it can affect the texture.
- Divide Batter Evenly – Use a kitchen scale or measuring cups to divide the batter into six equal portions for even rainbow layers.
- Layering Tip – To prevent colors from mixing, gently spoon the batter into the cupcake liners and spread it carefully with a spoon or offset spatula.
- Don’t Overfill Liners – Fill cupcake liners about ⅔ full to allow room for rising without overflowing.
- Perfectly Baked Cupcakes – Check cupcakes at 18 minutes by inserting a toothpick in the center. If it comes out clean, they’re ready!
- Gold Filling Tips – Let the white chocolate ganache cool slightly before adding luster dust to ensure a smooth, shiny gold finish.
- How to Core the Cupcakes – Use a small knife, cupcake corer, or even a large piping tip to remove the center for the gold filling.
- Best Frosting Texture – Whip the butter well before adding powdered sugar to create a light, fluffy frosting. Add heavy cream slowly to control consistency.
- Frosting Piping Tip – Use a 1M or 2D piping tip for a beautifully swirled frosting effect.
- Extra Decorations – Top with gold sprinkles, edible glitter, or rainbow candies for a more festive look.
- Storage Tips – Store in an airtight container at room temperature for up to 2 days or in the refrigerator for up to 5 days. Let chilled cupcakes sit at room temperature before serving.
- Make Ahead Option – Cupcakes can be baked and frozen (without frosting) for up to 2 months. Thaw before decorating.
