Sweetened Condensed Oat Milk

Sweetened Condensed Oat Milk is a homemade plant-based sweetener milk made by blending oats with water, then slowly heating the strained oat milk with cane sugar. A touch of vanilla and salt finishes the mixture, resulting in a creamy, lightly sweet milk alternative similar in consistency to traditional condensed milk. Optional vegan butter can enrich the flavor and mouthfeel.

Ingredients

  • ½ cup rolled oats see Note 1
  • 2 cups water ice cold
  • ½ cup organic cane sugar see Note 2
  • ¼ teaspoon vanilla extract real or clear/imitation vanilla
  • pinch of salt
Optional addition:
  • 1 to 2 tablespoons vegan butter for a richer flavor and mouthfeel, optional

Instructions

    Cup of Yum
  1. Place oats in a strainer and rinse briefly under cold water. Combine the oats and 2 cups cold water in a blender. Start on low speed and quickly increase to high. If using a high-speed blender like a Vitamix, blend for just 30 seconds. In a regular blender, you may need to blend longer, closer to 1 minute. Strain the oat milk twice. I like to use two nut milk bags, one inside the other, and strain it once through the double layer.
  2. In a medium-large saucepan, whisk together the oat milk and sugar. Turn on the burner to medium heat, and slowly heat the mixture while whisking frequently. It should take about 5 minutes for the milk to get steamy and hot. Reduce the heat as needed so it doesn't reach a full boil.
  3. Once the milk is hot, slightly thickened, and close to a simmer, reduce the heat to low and cook for another 2 ½ to 3 minutes (not longer). It should look glossy and thickened yet still somewhat thin. Turn off the heat, and whisk in the vanilla and salt. Set aside to cool.
  4. Option: if you prefer a richer condensed milk, whisk in the vegan butter now. (The batch in the photos did not include vegan butter.)
  5. Pour the condensed oat milk into a lidded jar or container, and store in the refrigerator for up to 6 days or freezer for up to 2 months.

Notes

  • If using commercial oat milk, whisk in 1 teaspoon of corn starch or arrowroot starch per cup before heating to achieve thickening.
  • Maple syrup may replace cane sugar but may alter texture and sweetness.
  • Maintain low heat without boiling to avoid burning and achieve proper thickening.
