This marbled rainbow donut recipe has become my go-to centerpiece for children's parties and special breakfasts. The striking swirls of color transform simple store-bought donuts into magical creations that never fail to impress guests of all ages.

I first created these for my daughter's unicorn-themed birthday party, and the gasps from both children and adults when they saw the vibrant display made all the simple prep work worthwhile. Now they're requested for almost every special occasion in our home.

Ingredients

  • Plain non-glazed donuts: From local donut shop provides the perfect blank canvas for your rainbow masterpiece
  • Powdered sugar: Creates the smooth base for your colorful glaze
  • Water: Just enough to achieve the perfect dripping consistency
  • McCormick Neon Food Coloring: Gives you those vibrant unicorn-worthy hues
  • McCormick Regular Food Coloring: Complements the neon colors for a full rainbow effect
  • Wax paper: Essential for allowing donuts to dry without sticking

Step-by-Step Instructions

Prepare the Sugar Glaze:
Measure half cup powdered sugar into each of six small bowls. Add one teaspoon of water to each bowl and stir until you achieve a thick syrupy consistency. The glaze should flow slowly but not be watery. Add food coloring two drops at a time until you reach your desired vibrancy. For best results create six distinct colors pink, yellow, green, blue, purple, and orange.
Create the Marbling Effect:
Using a spoon, draw thick lines of each colored glaze side by side on a plate. The colors will naturally begin to blend at the edges. Take a toothpick and gently swirl the colors together, creating your preferred pattern. Be careful not to overmix or you will lose the distinct color separation that makes the marbling so beautiful.
Glaze the Donuts:
Place each donut face down into the swirled glaze, pressing gently to ensure complete coverage. The trick is applying even pressure all around the donut. Use a toothpick to pop any air bubbles that form. Carefully lift the donut and place it glazed side up on wax paper. Refresh your marbled plate with new lines of glaze after every two or three donuts.
Final Touches:
Examine each donut for any bare spots. Once the first layer has partially set, you can apply a second coat if needed. Multiple layers actually create an even more dimensional effect with additional swirls and patterns. Allow donuts to dry completely for at least 4 hours or ideally overnight before serving.

My favorite part of making these rainbow donuts is watching my children's faces light up when they see the swirls of color. There's something magical about transforming a simple donut into something so visually spectacular with such minimal effort. My daughter now calls them unicorn donuts and insists they have special powers.

Storage Tips

These marbled donuts should not be stored in an airtight container or refrigerator as the glaze will become sticky and lose its beautiful finish. Instead, place them on a plate and store uncovered on your counter for up to two days. If ants are a concern in your home, store them on a plate inside your microwave, not turned on of course, which provides an insect-proof environment.

Customization Ideas

While rainbow colors create a magical unicorn effect, you can easily adapt the color palette to match any theme. Try team colors for sports parties, pastel hues for baby showers, or holiday-specific combinations like red and green for Christmas. You can also add edible glitter or sprinkles while the glaze is still wet for extra sparkle. Just remember that simple is often more striking when it comes to the marbled effect.

Serving Suggestions

Display these donuts on a tiered cake stand for maximum visual impact at parties. For birthday celebrations, arrange them in a circle on a large platter and place a candle in the center. They pair wonderfully with colorful fruit skewers and milk served in mason jars with paper straws to continue the festive theme. At breakfast gatherings, balance the sweetness with a savory egg dish on the side.

Ingredients

→ For the Base

01 1 dozen plain, non-glazed donuts

→ For the Rainbow Glaze

02 3 cups powdered sugar
03 6 teaspoons water
04 Neon food coloring
05 Regular food coloring

Instructions

Step 01

Place ½ cup powdered sugar in each bowl. Add 1 teaspoon of water to each bowl and mix until the consistency is like syrup. Add food coloring 2 drops at a time until desired color is achieved. Create 6 different colors (pink, yellow, green, blue, purple, etc.).

Step 02

Using a spoon, draw a thick line of each colored sugar glaze on a plate. Place all colors side by side; they will start to blend together. Take a toothpick and swirl the colors together into the desired pattern.

Step 03

Place the donut face down in the sugar glaze. Lightly press down all around to ensure complete coverage. Pop any bubbles that form with a toothpick. Place the glazed donut on a cookie sheet lined with wax paper. Add more lines of colored glaze to the plate after every couple of donuts.

Step 04

If the glaze appears too thin or areas were missed, apply a second coat once the first layer has partially dried. Let dry completely before serving. Do not place in an airtight container or refrigerator to avoid sticky glaze. Store on the counter until ready to serve.

Notes

  1. Each donut will have a unique marbled pattern.
  2. For ant protection, store on a plate in the microwave (not turned on).
  3. Best made the day before serving to allow the glaze to set properly.
