Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

• 8 cups water, divided
• 1 cup quick-cooking oats
• 1 cinnamon stick
• 1/2 cup white sugar
• 2 teaspoons vanilla extract

Optional garnish ideas:

• Ground cinnamon
• Ice cubes
• Cinnamon sticks
• Thin oat sprinkle on top

Directions

1. Add 5 cups of water, the quick-cooking oats, and the cinnamon stick to a blender.
2. Blend the mixture on high speed for about 1 minute, or until the oats and cinnamon are well combined and the liquid looks creamy.
3. Place a fine mesh strainer over a large pitcher. Carefully pour the blended mixture through the strainer to separate the liquid from the oat solids.
4. Use a spoon to gently press the solids so more liquid passes through. Discard the remaining solids or save them for smoothies or baking recipes.
5. Pour the remaining 3 cups of water through the strainer into the pitcher to capture any remaining oat flavor.
6. Add the sugar and vanilla extract to the pitcher. Stir well until the sugar fully dissolves.
7. Refrigerate the drink for about 1 hour or until completely chilled.
8. Serve cold over ice and garnish with a sprinkle of cinnamon if desired.

Variations

• Use old-fashioned oats instead of quick oats for a slightly heartier texture.

• Add a pinch of ground nutmeg or cardamom for extra warmth and spice.
• Blend in a small amount of sweetened condensed milk for a richer version.
• Add fresh fruit such as strawberries or bananas for a fruity twist.
• For a lighter sweetness, reduce the sugar to 1/3 cup.
• Stir in a splash of almond milk or coconut milk for added creaminess.

Storage/Reheating

Store Agua de Avena in a covered pitcher or airtight container in the refrigerator for up to 3 days. Stir well before serving because the oats may naturally settle at the bottom.

This drink is best served cold and does not require reheating. If it becomes too thick after refrigeration, simply add a little cold water and stir until smooth again.
