Instructions
Make the Donut Dough
In a bowl, stir together warm milk, yeast, and a pinch of sugar. Let sit for 5–10 minutes until foamy.
Add flour, remaining sugar, salt, egg, and softened butter. Mix into a soft dough, then knead for 5–7 minutes until smooth and elastic.
Transfer to a greased bowl, cover, and let rise in a warm place for 1 hour or until doubled.Shape and Fry the Donuts
Roll out the dough to about ½ inch thick. Cut into rounds using a 3-inch cutter.
Place on a parchment-lined tray, cover loosely, and let rise again for 30–40 minutes.
Heat oil in a deep pot to 350°F (175°C). Fry donuts 1–2 minutes per side until golden. Drain on a cooling rack or paper towels.Make the Rainbow Custard
In a saucepan, heat milk until steaming. In a bowl, whisk yolks, sugar, and cornstarch until smooth.
Gradually whisk hot milk into the yolk mixture. Return to the pan and cook over medium heat, stirring constantly, until thickened.
Remove from heat, stir in butter and vanilla. Divide into separate bowls and color each with a different food dye.
Transfer each color to a small piping bag, then load them all into one large bag fitted with a round tip to create a swirl.Fill the Donuts
Use a straw or small knife to poke a hole in the side of each donut. Pipe in the rainbow custard gently, just until the donut feels full.Glaze and Decorate
Whisk powdered sugar, milk, and vanilla into a smooth glaze. Dip each donut top and decorate with rainbow sprinkles or glitter.
Let set for 10–15 minutes before serving.
Notes
For the boldest colors, use gel food coloring—it won’t water down your custard.
Be careful not to overfill the donuts or they may split. A light hand goes a long way!
Store filled donuts in the refrigerator and enjoy within 2 days. For best texture, let them come to room temp before serving.
Want a shortcut? You can use store-bought custard, but trust me, homemade is worth it.
Customize the colors for any holiday or theme—pastels for Easter, red and green for Christmas, or red-white-blue for the 4th of July!
