That's why I'm so excited to talk about my recipe for protein coffee overnight oats - an incredibly tasty and easy way to start your day off right.
This delicious and protein-packed breakfast takes only minutes of prep time the night before. The busy mornings are made even easier since we are preparing and adding coffee to our breakfast the night before.
I love adding in collagen powder to my overnight oats, since it is such an easy and quick way to add a protein boost in the morning. The combination of protein and whole grains is a nutritious way to start the morning and leaves me feeling full and satisfied until lunch.

How to Make Protein Coffee Overnight Oats
Combine all of the ingredients
Combine all of the ingredients for the overnight oats in a clean glass mason jar or ceramic container and leave in the fridge for at least 4 hours or overnight.

Add yogurt on top
Once the oats and chia seeds have fully absorbed the liquid, spread a layer of greek yogurt on top. If you'd like, sift cacao powder on top for a chocolatey kick.

Substitutes for Coffee Overnight Oats
If you're not a fan of maple syrup, there are many options for alternate liquid sweeteners that can make the oats just as tasty. Honey is a great option for those looking for a milder sweetness, while agave nectar provides a slightly more intense sweetness. Brown sugar syrup and date syrup are other good choices for added depth of flavor.
A great substitute for espresso shots in this recipe can be ½ cup of freshly brewed coffee or cold brew. This recipe would be a great place to use any leftover coffee you might have from the morning. You could also use ½ teaspoon of espresso powder and ½ cup of water to make instant espresso.
For those that don't have access to chia seeds, flaxseed makes a great alternative. If you'd like, you can combine both chia and flax together for an even more healthy fats in the morning.
You do not need to add yogurt to this overnight oats recipe if you don't have any yogurt or don't want to. I like the added boost of protein that it gives, but it is optional.
