Coffee Overnight Oats are a delicious way to perk yourself up in the morning! Just five minutes of work before you go to bed and you'll have an easy breakfast that has cold brew coffee in it to get you started. A must try recipe for coffee lovers! This recipe is dairy free and gluten-free as well!

Hey Internet, we've got another breakfast recipe for you today. Breakfasts can be so hard to make. Not only are you trying to rush out the door, you're probably groggy. Unless you're Paul, then you apparently wake up at the crack of dawn and are fully awake. Certain people need to learn to sleep in.

We've made a lot of easy plant-based breakfast recipes, like our Tofu Scramble and our Chia Seed Puddings like Chocolate Peanut Butter Chia Pudding. These are great in their own ways, but we really wanted to experiment with adding a little bit of caffeine to our breakfast food. I mean, it works great in our Matcha Pound Cake: it's solid but it can really give you a jolt! 

But it's more of a dessert. Of course that doesn't stop some people from having cake for breakfast! I've been known to indulge...

We developed this recipe for a little less crazy start to the day. This overnight oats recipe uses a little cold brew for caffeine and a really nice coffee flavor that pairs well with the old-fashioned oats, soy milk (or any milk), vanilla, and chocolate flavors that recipe has. And it's so easy: just add the ingredients to a mason jar and let it soak in the fridge overnight. Add this to your list of easy breakfasts.

Why You'll Love Coffee Overnight Oats

  • 5 Minutes to Make: Place the ingredients in glass jars, stir, and then store for a delicious breakfast!
  • Simple Ingredients: With just 7-8 ingredients that are easy to find, you'll be to make this recipe all the time.
  • Coffee, Coffee, Coffee: Awesome flavors that boost you up.
  • Top It: Top with anything you like, from vegan Greek yogurt or any kind of yogurt (try our homemade soy yogurt too), mini dairy-free chocolate chips, cacao nibs, walnuts, a drizzle of almond butter or peanut butter, or even dark chocolate covered coffee beans!

Ingredients

Pick up these simple ingredients the next time you're at a grocery store. See the recipe card at the bottom of this post for full ingredients, instructions, and accurate nutritional information (to the best of my ability; please consult your physician or healthcare professional if you have specific dietary needs). I give substitutions for the ingredients in the section below this one, so most people can still make this recipe!

  • 0.5 Cup Rolled Oats
  • 1 Tablespoon Chia Seeds
  • 0.5 Cup Soy Milk
  • 0.25 Cup Cold Brew Coffee
  • 0.5 Teaspoon Vanilla Bean Paste
  • 1 Tablespoon Pure Maple Syrup
  • Pinch of Salt
  • 1 Tablespoon Cacao Nibs, Optional

Substitutions

  • Soy Milk: Oat milk, cashew milk, and almond milk are all dairy-free milk that will work just as well! Soy milk is ideal because it is just slightly sweet and has extra protein for your coffee oats recipe. The kind of soy milk we buy is high in protein too!
  • Cold Brew Coffee: Instant coffee can be used. Pour 0.25 cup warm water into a measuring cup and stir in the instant coffee. Cold brew concentrate can also be used, but you might need to compensate with extra milk to replace the missing liquid (make sure to follow directions on the bottle when reconstituting). It can be great if you're an absolute coffee lover! You can use brewed coffee too!
  • Maple Syrup: Agave syrup and date syrup are also great natural sweeteners that you can use instead. Or try our homemade vegan honey!
  • Vanilla Bean Paste: Vanilla Extract can be used instead. Add a few drops at a time to make sure it's not overpowering.
  • Cacao Nibs: These chocolate chips can be used instead. They'll just be less earthy. Which can be good! You could also try a chocolate protein powder but you'll want to mix it into your oats before refrigerating, and you may need to add more liquid.

How to Make Coffee Overnight Oats

  1. Add Liquids: Place the plant-based milk, cold brew coffee, vanilla bean paste, and maple syrup to a mason jar and stir them together.
  2. Add Solids: Add the oats, chia seeds, and salt and stir them together. Taste the mixture now to make sure you like it. Need it sweeter? Add a little more maple, stir, and try again.
  3. Refrigerate: Seal the jar and place in the fridge for at least 6 hours or overnight.
  4. Serve: Open the jar and top with cacao nibs and any other toppings you want.

Storage Instructions

Since you're already using an airtight container for this recipe, it stores itself! Just keep in cool in a refrigerator and it will keep for about an entire week. It's great for meal prep and busy mornings! 

Frequently Asked Questions

Can I Do Anything if I Find These Oats too Wet/Solid?

Just make slight adjustments to the liquids and solids to get the texture right. It may take some experimenting to get it to your liking.

What Other Toppings Could I Add?

Chopped walnuts, some plant-based yogurt, or some coconut whipped cream would all be great choices.

Can I Use Steel Cut Oats or Quick Oats?

Out of the bag, steel-cut oats will take too long to absorb the liquids. You can try boiling these oats in the milk to make them more permeable. We still recommend using rolled oats for this recipe. Quick oats have the opposite problem and absorb too quickly. You'll have to eat the quick-cooking oats version within a day before they become gross.
