FAQ
Can I add extra protein powder to this recipe?
Yes, this recipe only calls for 1/2 scoop per serving and it will get you 30 g of protein for the whole recipe. If you want you could add a whole scoop of protein to this recipe bringing your total to 45 grams of protein.
What kind of milk can I use in this recipe?
Personally, I use Fairlife 2% milk. You can use any brand, however, I would recommend that you stick with a reduced-fat version.
Also, if you are looking to void dairy feel free to use tree nut milk like almond milk.
How long will these oats last in the fridge?
These oats will last in the fridge for 3-5 days. After that, they start to get a little bit too soggy for my liking. Plus you are running into food safety issues after those 5 days
Can I heat these oats up?
Yes, you can heat these oats up. I would recommend doing so in 30-second intervals so that you don’t overcook them. Once heated, top with an additional banana or chocolate chips.
