Ingredients
- 1 cup certified gluten-free oats
- 4 cups water
- 0.5 cup unsweetened almond milk
- 0.5 cup sugar or other sweetener (adjust to taste)
- 1 tsp ground cinnamon
- 0.5 tsp pure vanilla extract
- 1 pinch salt
- 1 cup ice cubes
Instructions
- 1
In a medium bowl, combine the certified gluten-free oats with 4 cups of water. Let them soak for at least 30 minutes, or up to 2 hours, to soften. This step is crucial for achieving a smooth texture and extracting the oat flavor.
- 2
Drain the soaked oats thoroughly, discarding the soaking water. Transfer the drained oats to a high-speed blender.
- 3
Add the unsweetened almond milk, sugar, ground cinnamon, pure vanilla extract, and a pinch of salt to the blender with the oats. Blend on high speed for about 60-90 seconds, or until the mixture is completely smooth and creamy. You should notice a pleasant aroma of cinnamon and vanilla.
- 4
Strain the horchata mixture through a fine-mesh sieve or cheesecloth into a pitcher or bowl. Press gently to extract as much liquid as possible, leaving behind any remaining oat pulp. This process ensures a silky smooth beverage.
- 5
Taste the horchata and adjust the sweetness with more sugar or sweetener if desired. Stir well to incorporate any added sweetener. Chill the horchata in the refrigerator for at least 1 hour to allow the flavors to meld and the drink to become thoroughly cold.
- 6
To serve, fill glasses with ice cubes and pour the chilled horchata over the ice. Garnish with a sprinkle of ground cinnamon, if desired. Enjoy this refreshing and authentic-tasting gluten-free horchata immediately.

Tips & Notes
- Certified gluten-free oats vary by cut; any cut works in no-bake recipes, but certified gluten-free rolled oats hold their shape better when baked.
- Any plant-based milk works here — oat milk (certified GF) gives the richest mouthfeel; almond milk keeps it lighter.
- Scrape a real vanilla bean pod into the batter and steep the pod in warm milk for 10 minutes for intense flavor.
