Spray a muffin tin with non-stick cooking spray and scoop oatmeal mixture in using a large ice cream scoop (or a 1/4 measuring cup). The mixture will be a little watery, so it’s important to mix the oatmeal well before each scoop to make sure you get an even combination of milk and oats.
Bake oatmeal cups for 20 minutes, or until cooked through.
Remove from oven and let cool for a few minutes. Enjoy immediately or let them cool completely and place them in a freezer-safe container. Pull out of the freezer as needed and heat them up in the microwave for about 60-90 seconds.
Notes
If you don't like strawberries, you can swap them out for blueberries (fresh or frozen), raspberries, or blackberries.
