Simple as can be:

1. Soak 1.5 cups gluten free rolled oats in a nut milk bag overnight (8-12 hrs) with 4 cups of filtered water.
2. Squeeze all the liquid from bag, refrigerate and enjoy!

(Can be stored in the fridge for up to 5 days.)

*Heads up, the consistency is very gooey. If you have kids, this is a wonderful sensory activity for them to help out with. The gooey oats that remain afterwards can also be a lot of fun to play with. Hint: try adding natural food coloring and toys to the mix as well.
