I love coffee and morning oats so combining the two felt so natural! And I must admit, the flavor in these oats is so much better than I imagined. It almost reminds me of tiramisu!

And because I love both chocolate mochas and vanilla lattes I made two versions of these oats to let you choose which one sounds best to you! Both are equally good. Can’t go wrong.

Why This Recipe Works

  • Soaking the oats over night in oat milk creates the best, creamy, silky texture.
  • Instant coffee adds the perfect coffee taste without needing to take extra time to brew any coffee, espresso, or cold brew.
  • My vegan caramel recipe mixed with cacao powder makes for the best WFPB mocha sauce! No refined sugars needed.

Ingredient Notes

Ingredients for coffee overnight oats.
  • rolled oats – The best type of oats to use for making overnight oats. They are soft enough to soften overnight in the milk, but hearty enough to still leave some hearty, chewy texture! Steel cut oats are too tough and unprocessed to soften properly overnight and instant oats are too processed to hold any texture at all.
  • oat milk – My favorite type of plant-based milk for overnight oats because it’s so creamy. Oat milk also has a natural sweet undertone. If needed, substitute with soy milk or any other unflavored plant-based milk.
  • vegan caramelMy 4 ingredient homemade caramel that is Medjool date based! Gives these oats the best sweetness and flavor while keeping the recipe healthy and refined sugar free.
  • cacao powder – Gives the mocha flavored oats the indulgent chocolate flavor and a boost of antioxidants without additional sugar!
  • instant coffee – Easy coffee flavor! I used Folgers Classic Roast Instant Coffee Crystals. If desired, substitute with a 1/4 cup of coffee or cold brew and leave out the 1/4 cup of water. You could also substitute the instant coffee and water with two shots of espresso for an extra good caffeine boost!
  • chia seeds – Thickens these oats perfectly while adding a boost of omegas. I don’t recommend substituting with flax seeds as it makes the texture of the oats slimy.
  • vanilla extract – For the classic vanilla latte flavor. Feel free to add a little vanilla to the mocha oats, too! You can substitute vanilla paste or even scraped fresh vanilla pods.

Step by Step Instructions

Step by step how to make Overnight Oats.
  1. Add all of the ingredients together in a 16 ounce jar with a lid.
  2. Mix ingredients together until well incorporated. Make sure all of the chia seeds are submerged in liquid so they can absorb the liquid properly!
  3. Cover oats with an airtight lid and refrigerate overnight for at least 6 hours.
  4. Enjoy next morning! Add a splash of milk, additional sweetener, or coconut whipped cream to make it extra fun.

FAQs

Can I eat these overnight oats warm?

These oats are meant to be eaten cold straight from the refrigerator but you can heat them up in the microwave if you prefer! If you like warm oats, you may like my Instant Pot Oatmeal with Steel Cut Oats recipe better.

Can I make these for meal prep?

Yes, overnight oats will last in the refrigerator for up to 5 days so feel free to batch 5 servings on Sunday night and eat them throughout the week! Super great and easy.

What can I substitute for the vegan caramel?

I really recommend the vegan caramel recipe as it’s super easy to prepare (10 minutes!) and really makes these oats taste like a latte/mocha.

I’m out of rolled oats. Can I substitute steel cut oats or quinoa?

No, steel cut oats are very different than rolled oats. They take far longer to cook and require more liquid. If you use steel cut oats these oats will be very chewy and unfavorable in texture.

Quinoa also cannot be substituted as it needs to be cooked before eating. You cannot soak raw quinoa like you can oats.

Expert Tips

  • If making this for meal prep, prep each serving in it’s own individual jar as opposed to in a large container. This makes it easier to grab and go in the mornings.
  • Don’t try to substitute the caramel. It seriously makes the biggest difference in making this recipe taste like a latte or mocha. I tested this recipe with just maple syrup and other various sweeteners and none compared to the flavor of the oats made with the caramel. It really makes the oats taste like an actual, coffee shop quality latte!
