How to Homemade Oat Milk Recipe
Follow these simple steps to create delicious, non-slimy oat milk in your own kitchen.
Step 1: Dissolve Sweetener
Stir the vanilla and brown sugar into the cold water until dissolved. Make sure the sugar is fully dissolved to prevent a gritty texture in your final product.
Step 2: Blend Ingredients
Add the rolled oats, salt, and the cold water mixture to a blender. For the best texture, also add a pinch of baking soda (⅛ tsp per 4 cups of water) now. Blend on high for 30 seconds. Be careful not to over-blend, as this can lead to a slimy texture.
Step 3: Strain the Mixture
Pour the blended oat mixture through a strainer to filter out the oat pieces. You can use a nut bag, cheesecloth, a metal coffee filter, or even a double layer of sieves. A nut bag is reusable and very effective. Cheesecloth is inexpensive, but might let some sediment through. Avoid squeezing the bag too hard, as this releases more starch and can cause a slimy texture.
