Optional Add-Ins for the Overnight Oats
‘Kay, these are obviously delicious on their own, but if you want to amp up the flavor (or nutrition!) even more, here are some super fun add-ins that I’ve tested that taste AMAZING in these oats:
- A dollop of peanut butter for peanut chocolatey goodness!
- A scoop of protein powder for some extra protein!
- A sprinkle of coconut flakes on top to add some more flavor.
- A drizzle of melted chocolate to amp up the chocolatey-ness even more!
- A handful of fruit, like strawberries, to add some extra fiber.

What Kind of Oats Should I Use?
I’ve tested this recipe using large flake oats and quick oats, and I much prefer the large flake oats.
While you technically can use the quick oats instead if that’s all that you have on hand, I found that the quick oats got kinda mushy, and didn’t have the best texture compared to the large flake oats.
