Vegan Custard Recipe

4.4 from 84 reviews

This creamy vegan custard recipe uses oat milk and cornstarch for a smooth, dairy-free dessert that’s naturally sweetened and flavored with vanilla bean paste. It’s quick to make on the stovetop and perfect for those seeking a comforting, plant-based treat without eggs or dairy.

Ingredients

Scale

Custard Base

  • 2 1/3 cups full-fat oat milk
  • 1/2 cup cornstarch
  • 1/2 cup granulated sugar
  • 3/4 teaspoon vanilla bean paste
  • 1 pinch turmeric (optional, for color)

Instructions

  1. Whisk base: In a medium bowl, combine the oat milk and cornstarch, whisking thoroughly until the mixture is smooth and free of lumps to ensure an even custard texture.
  2. Thicken: Transfer the mixture to a medium saucepan and stir in the granulated sugar. Place over medium heat and continuously stir the mixture until it reaches a simmer and thickens, which should take about 5 to 10 minutes. Constant stirring prevents lumps and burning.
  3. Flavor: Remove the saucepan from heat and stir in the vanilla bean paste for flavor. If desired, add a pinch of turmeric to give the custard a warm yellow hue, mixing well to combine.
  4. Chill: Pour the custard into a bowl and cover the surface directly with plastic wrap to prevent a skin from forming. Let it cool completely at room temperature, then refrigerate it until fully chilled before serving.

Notes

  • Use full-fat oat milk for a richer, creamier texture.
  • Turmeric is optional and used only for natural coloring.
  • Stir continuously while heating to avoid lumps and ensure smooth custard.
  • Covering the custard with plastic wrap directly on the surface prevents an unappetizing skin from forming as it cools.
  • Can be served warm after thickening or refrigerated for a chilled dessert.
