Ingredients
Here’s everything you’ll need to make one serving of horchata overnight oats:
- ½ cup old-fashioned rolled oats
- ¾ cup unsweetened rice milk
- 1 tablespoon sweetened condensed milk
- ½ teaspoon vanilla extract
- ½ teaspoon ground cinnamon, plus more for garnish
- 1 small cinnamon stick (for steeping, optional but recommended)
- 2 tablespoons sliced or slivered almonds
- Pinch of salt
Optional toppings: fresh fruit, additional sliced almonds, a drizzle of honey, or a sprinkle of ground cinnamon.
Step-by-Step Instructions
Step 1: Warm the Rice Milk (Optional but Worth It)
For a deeper, more authentic horchata flavor, gently warm your ¾ cup of rice milk in a small saucepan over low heat. Add the cinnamon stick and let it steep for about 5 minutes — do not boil. Remove from heat, discard the cinnamon stick, and allow the milk to cool completely before using. This step is optional if you’re short on time, but it genuinely elevates the flavor of your horchata overnight oats.
Step 2: Mix the Base
In a mason jar or airtight container, combine the ½ cup of rolled oats, the cooled (or room temperature) rice milk, sweetened condensed milk, vanilla extract, ground cinnamon, and a small pinch of salt. Stir everything together thoroughly until well combined, making sure the cinnamon is evenly distributed and doesn’t clump.
Step 3: Add the Almonds
Stir in 1 tablespoon of your sliced almonds directly into the oat mixture. This allows them to slightly soften overnight, adding a pleasant texture contrast. Reserve the remaining tablespoon for topping in the morning so you still get that satisfying crunch.
Step 4: Refrigerate Overnight
Seal your jar or container tightly and place it in the refrigerator. Let the oats soak for at least 6 hours, though 8 hours (overnight) is ideal. During this time, the oats will absorb the rice milk and all those wonderful horchata-inspired spices, resulting in a thick, creamy, and incredibly flavorful breakfast.
Step 5: Serve and Enjoy
In the morning, remove your horchata overnight oats from the refrigerator and give them a good stir. If the mixture is thicker than you’d like, simply add a splash of rice milk to loosen it up. Top with the reserved sliced almonds, a dusting of ground cinnamon, and any other toppings you love. Enjoy cold, or warm briefly in the microwave for 60–90 seconds if you prefer a warm breakfast.
Expert Tips for Perfect Horchata Overnight Oats
- Use old-fashioned rolled oats: Quick oats tend to become mushy overnight, while steel-cut oats may remain too chewy. Old-fashioned rolled oats hit the perfect creamy-yet-textured sweet spot every time.
- Don’t skip the pinch of salt: A tiny amount of salt balances the sweetness of the condensed milk and enhances the cinnamon flavor in a way that’s subtle but surprisingly impactful.
- Steep the cinnamon stick if you can: This small extra step is what takes your horchata-flavored overnight oats from good to absolutely incredible — it mimics the traditional horchata flavor profile beautifully.
- Adjust sweetness to taste: Sweetened condensed milk is rich, so start with 1 tablespoon and taste the mixture before refrigerating. Add a little more if you prefer a sweeter breakfast, or substitute with maple syrup for a lighter touch.
- Make it dairy-free: Sweetened condensed milk is the one non-dairy ingredient here. Look for coconut-based condensed milk at most health food stores — it works wonderfully and adds a subtle tropical note that pairs beautifully with cinnamon.

Frequently Asked Questions
Can I make horchata overnight oats ahead of time for meal prep?
Absolutely! This recipe is a meal-prep superstar. You can prepare up to 4–5 jars at once and store them in the refrigerator for up to 5 days. Just add your fresh toppings each morning to keep things crisp and vibrant. It’s one of the easiest ways to guarantee a delicious, healthy breakfast all week long.
Can I use a different type of milk instead of rice milk?
Yes, you can! Rice milk is traditional for horchata and delivers the most authentic flavor, but oat milk, almond milk, or even regular dairy milk all work wonderfully. Almond milk is a particularly great alternative because it echoes the nutty almond notes already present in the recipe.
Are horchata overnight oats served cold or warm?
They’re delicious either way! Most people enjoy overnight oats cold, straight from the fridge. However, if you prefer a warm breakfast — especially in winter — simply transfer them to a microwave-safe bowl and heat in 30-second intervals, stirring between each, until warmed to your liking. Add a splash of rice milk if needed to restore creaminess.
Can I make this recipe vegan?
Yes, with one simple swap! Replace the sweetened condensed milk with coconut condensed milk (widely available at grocery and health food stores) or use maple syrup and a tablespoon of coconut cream as an alternative. All other ingredients in this cinnamon overnight oats recipe are naturally plant-based.
What other toppings go well with this recipe?
The possibilities are delicious! Fresh mango or strawberries complement the horchata flavor beautifully. Toasted coconut flakes, a drizzle of honey or agave, chopped dates, or even a few dark chocolate chips are all wonderful additions. A sprinkle of extra ground cinnamon on top is practically non-negotiable for that signature horchata look and aroma.
There’s truly nothing like waking up to a jar of horchata overnight oats already waiting for you — creamy, fragrant with cinnamon, and ready to make your morning feel a little more special.
