Hot Chocolate Overnight Oats

WANT TO SAVE THIS RECIPE?

If you’ve ever wanted dessert for breakfast without the guilt, these Hot Chocolate Overnight Oats are exactly what you need.

The next day, I woke up to a creamy, cocoa-infused jar of oats that tasted like a mug of hot chocolate—only chilled and spoonable. It felt like a little indulgence, but one that left me energized instead of sluggish.

What Kind of Cocoa Powder Should I Use?

I recommend using unsweetened cocoa powder for this recipe. It gives you that deep, rich chocolate flavor without added sugar, which allows you to control the sweetness. Dutch-processed cocoa works well too if you prefer a smoother, slightly less bitter taste. If you want to turn things up, try cacao powder—it’s less processed and full of antioxidants.

Options for Substitutions

• Milk: Any type of milk works—almond, oat, soy, dairy, or coconut. Just use your favorite or whatever you have on hand.
• Sweetener: Maple syrup, honey, agave, or even mashed banana can be used to sweeten the oats naturally.
• Yogurt: If you want extra creaminess and protein, swap half the milk for Greek yogurt or a dairy-free alternative.
• Chocolate Chips: These are optional but fun. Use dark, milk, or mini chips depending on your preference.
• Toppings: Whipped cream, nut butter drizzle, or a sprinkle of cinnamon or sea salt adds a finishing touch.

• Chia seeds: Help thicken the mixture and add a boost of fiber and omega-3s.
• Unsweetened cocoa powder: The star ingredient that gives the oats their rich hot chocolate flavor.
• Milk of choice: Provides creaminess—almond milk, oat milk, or dairy milk all work well.
• Maple syrup: Naturally sweetens the oats and enhances the cocoa flavor.
• Vanilla extract: Adds warmth and depth to the chocolate.
• Pinch of salt: Balances the sweetness and deepens the chocolate taste.

Step 1: Combine Dry Ingredients

In a medium-sized mason jar or bowl, add the rolled oats, chia seeds, and cocoa powder. Mix well to ensure the cocoa powder is evenly distributed throughout the dry ingredients.

---

Step 2: Add Wet Ingredients

Pour in your milk of choice, maple syrup, and vanilla extract. Stir thoroughly so the oats are completely soaked and there are no lumps of cocoa powder.

---

Step 3: Add a Pinch of Salt

Don’t skip this step! A small pinch of salt brings out the depth of the chocolate and balances the sweetness.

---

Step 4: Stir in Chocolate Chips (Optional)

If you want melty bits of chocolate throughout, stir in a few mini chocolate chips now. Otherwise, save them for topping just before serving.

---

Step 5: Seal and Refrigerate Overnight

Cover your jar or bowl with a lid or plastic wrap. Refrigerate for at least 6 hours, preferably overnight. This allows the oats and chia seeds to absorb the liquid and thicken to a pudding-like consistency.

---

Step 6: Serve and Garnish

In the morning, give your oats a good stir. Add a swirl of whipped topping, a sprinkle of cinnamon, and a few more chocolate chips if desired. Enjoy cold, straight from the jar.

How Long to Prepare the Hot Chocolate Overnight Oats

Prep Time: Preparing these oats takes just about 5 minutes. That includes measuring, mixing, and sealing everything in a jar or container. It’s the kind of recipe that fits effortlessly into your nighttime routine.

Chill Time: For best texture, the oats need to chill in the fridge for at least 6 hours, but overnight is ideal. This allows the chia seeds and oats to fully absorb the liquid and create that creamy, pudding-like texture.

Tips for Perfect Hot Chocolate Overnight Oats

• Use rolled oats instead of quick oats for a better texture.
• Mix your cocoa powder thoroughly with dry ingredients to avoid clumps.
• Let the oats sit for a minute after the first stir—then stir again to ensure everything is evenly combined.
• Taste and adjust sweetness before chilling if desired.
• For ultra-creamy oats, use half milk and half yogurt.

Watch Out for These Mistakes While Cooking

• Not mixing well: Cocoa powder tends to clump—stir extra well to blend it in fully.
• Using too much liquid: It can make the oats soupy. Stick to the suggested ratios.
• Skipping the salt: It may seem small, but it’s key for enhancing flavor.
• Forgetting to stir in the morning: Give the oats a good stir before serving to redistribute everything evenly.
• Adding toppings too early: Wait to add whipped cream or chips until serving so they don’t get soggy.
