Overnight Oats with Chia Seeds
It’s no secret that I’m pretty obsessed with overnight oats. From Carrot Cake Overnight Oats, to Tiramisu Overnight Oats and Strawberry Cheesecake Overnight Oats, there are so many great flavors to make! But making overnight oats with chia seeds is actually one of my favorite ways to incorporate more nutrition and create a thicker, heartier texture.
What Are Overnight Oats?
Overnight oats are a healthy breakfast or snack that are super easy to make and perfect for meal prep! They are usually eaten cold and consist of rolled oats, flavorings (spices, fruit, nut butter, & vanilla), and milk or yogurt. They’re versatile, can be made in just 5 minutes, and are truly the BEST healthy breakfast idea!

First time trying. VERY thick.
I would like it thinner. I am guessing just add more milk?
And how long are these able to keep in the frige? Can I make a weeks worth?
