Vegan Oat Milk Custard Recipe
Introduction
This vegan custard is a creamy, dairy-free dessert that’s simple to make and deliciously comforting. Made with oat milk and naturally thickened with cornstarch, it’s perfect for those seeking a plant-based treat without compromising on texture or flavor.

Ingredients
- 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 (for color, optional)
Instructions
- Step 1: In a bowl, whisk the oat milk and cornstarch together until smooth and free of lumps.
- Step 2: Transfer the mixture to a medium saucepan and stir in the granulated sugar. Heat over medium heat, stirring constantly until the custard reaches a simmer and thickens, about 5-10 minutes.
- Step 3: Remove the saucepan from heat and stir in the vanilla bean paste. If using, add a pinch of turmeric to achieve your desired color and mix well.
- Step 4: Pour the custard into a bowl and cover the surface directly with plastic wrap to prevent a skin from forming. Let it cool completely, then chill in the refrigerator if desired before serving.
Tips & Variations
- For a richer flavor, substitute some oat milk with coconut milk.
- If you prefer a sweeter custard, increase the sugar slightly to taste.
- Try adding a pinch of cinnamon or nutmeg for a warm spice twist.
- Use vanilla extract if vanilla bean paste is unavailable, though a bit less flavorful.
Storage
Store the vegan custard covered in the refrigerator for up to 3 days. Reheat gently in a saucepan over low heat, stirring constantly, or enjoy it cold directly from the fridge.

Can I use a different plant milk instead of oat milk?
Yes, you can use other full-fat plant milks like almond, soy, or coconut milk. Just be aware that the flavor and texture may vary slightly.
How can I prevent the custard from developing a skin on top?
Covering the surface of the custard directly with plastic wrap while it cools helps prevent a skin from forming. Make sure the wrap touches the custard completely.
