4 from 11 reviews

A creamy and naturally sweetened homemade sweetened condensed oat milk, perfect as a dairy-free substitute in desserts and beverages. This recipe blends rolled oats with cane sugar and vanilla, gently cooked to achieve a thick, luscious texture with a hint of vanilla and a touch of salt. Optionally enriched with vegan butter for a richer taste and smoother mouthfeel.

  • Total Time: 20 minutes
  • Yield: Approximately 1½ cups sweetened condensed oat milk

Ingredients

Main Ingredients

  • ½ cup rolled oats
  • 2 cups ice cold water
  • ½ cup organic cane sugar
  • ¼ teaspoon vanilla bean paste
  • Pinch of salt

Optional

  • 1 to 2 tablespoons vegan butter (for richer flavor and mouthfeel)

Instructions

  1. Rinse and Blend the Oats: Place the rolled oats in a strainer and rinse briefly under cold water to remove excess starch. Combine the rinsed oats with 2 cups of ice cold water in a blender. Start blending on low speed and quickly increase to high. If using a high-speed blender (like Vitamix), blend for about 30 seconds; if using a regular blender, blend for approximately 1 minute.
  2. Strain the Oat Milk: Strain the blended oat mixture twice through nut milk bags, using two layers for finer filtration, to remove oat pulp and achieve a smooth milk consistency.
  3. Heat and Sweeten: Pour the strained oat milk into a medium-large saucepan. Add the organic cane sugar and whisk to combine. Heat the mixture over medium heat, whisking frequently to avoid scorching. It should take about 5 minutes for the milk to become steamy and hot without reaching a full boil.
  4. Simmer and Thicken: Once hot and slightly thickened, reduce the heat to low. Let the oat milk cook gently for 2½ to 3 minutes, whisking occasionally. The mixture should look glossy and thickened but still somewhat pourable.
  5. Add Flavorings: Remove the saucepan from heat. Whisk in the vanilla bean paste and a pinch of salt to enhance the flavor.
  6. Optional Enrichment: If desired, whisk in 1 to 2 tablespoons of vegan butter to give the condensed oat milk a richer flavor and creamier mouthfeel.
  7. Store Properly: Transfer the sweetened condensed oat milk into a lidded jar or container. Store in the refrigerator for up to 6 days, or freeze for up to 2 months. Stir well before use if frozen.

Notes

  • Use rolled oats for best results as they blend smoothly and create creamy texture.
  • Organic cane sugar is preferred for a natural sweetness without added flavors.
  • Rinsing the oats before blending reduces sliminess.
  • Adjust the amount of vegan butter for desired richness.
  • Do not boil the mixture to prevent separation and bitterness.
