Ingredients You'll Need
Note: Full ingredients and amounts are listed in the recipe card below.
- Oats: The base of the recipe; rolled, instant, or quick oats all work. I recommend using Quaker brand.
- Water: Starts the cooking process and helps soften the oats.
- Whole Milk: Adds richness and creaminess; dairy or unsweetened plant milk can be used.
- Sugar: Sweetens the oatmeal; any sweetener works. I personally like using turbinado sugar with a little maple syrup.
- Cinnamon stick: Adds warm flavor while cooking; ground cinnamon or freshly grated nutmeg can be used if desired.
- Vanilla extract: Rounds out the flavor and adds aroma; omit if not on hand.
How to Make Avena con Leche
Note: Full instructions are provided in the recipe card below.
- In a medium pot, add the water and cinnamon stick and bring to a boil. Once it boils, cover the pot to prevent evaporation and let it simmer for 2 to 3 minutes to release its flavor.
- Reduce the heat to medium, add the sugar, and stir until dissolved. Add the oats and cook, stirring occasionally, for about 5 minutes. If using instant oats, cook for 2-3 minutes.
- Add the milk and cook, stirring constantly, until the oatmeal begins to thicken, about 5 minutes, or until the oats reach your preferred consistency.
- Remove the cinnamon stick, stir in the vanilla, and remove from the heat. Serve immediately, plain or with your favorite topping, if desired.

Hint: If you like your avena con leche creamier and are using old-fashioned oats, after cooking them for about 5 minutes, let them rest in the hot liquid for 10-15 minutes before continuing to cook. This helps the oats soften and thicken better.
Storage, Make Ahead, & Freezing
Storage: Store leftover avena con leche in an airtight container in the refrigerator for up to 2 days. Reheat gently on the stove or in the microwave, adding a splash of milk or water if needed.
Make Ahead: This oatmeal is best enjoyed fresh; I don't recommend making it ahead.
Freezing: Not recommended.
Camila's Tips & Variations
- Prevent Sticking: Stir the oatmeal constantly after adding milk to prevent it from sticking to the pot or boiling over.
- Sweeten to taste: Adjust the sugar or sweetener to your preference.
- Milk options: Use dairy or plant-based milk for a different flavor or creaminess.
- Oat type flexibility: Instant, quick, or rolled oats all work-adjust cooking time accordingly.
- Add toppings: Top with fruit, nuts, or a drizzle of maple syrup or honey for extra flavor and texture.
