📖Why My Recipe Works
When you use a high-quality protein powder and oats, you don't need to add milk. You can but oats will thicken plenty with just water.
🧾Ingredient Notes
- Oats- Old-fashioned rolled oats. Use gluten-free, if needed. Quick cook oats can be used but it is not recommended to make them more than one day ahead. I don't recommend steel-cut oats for cold soaking.
- Chia Seeds- Chia seeds give overnight oats that thick pudding-like texture and add extra nutrients but feel free to leave them out if you aren’t a fan.
- Kosher Salt- A little salt is needed to help bring out the nutty flavor in the oats and help your flavor mix-ins shine.
What Type of Protein Powder Should I Use?
The best type of protein powder really depends on your own personal preferences and whether or not you want vegan or gluten-free.
The recipe sticks with a basic vanilla flavor so you can dress up your completed oats with your own personal flavors, or whatever you have on hand!
