The only ratio you need to remember is 1:1. You'll soak 1 part rolled gf oats with 1 part liquid, overnight. Use less liquid if you want thicker oatmeal, more if you like it runny.
You can use water or any type of milk -- almond milk, soy milk, coconut milk -- and feel free to add even a splash of orange juice if that's your thing!
Sweeten and flavor the oatmeal with whatever appeals to you: raw honey, pure fruit jam, real maple syrup, cinnamon, vanilla extract, citrus zest … the list goes on. Then get creative: Add nuts, cacao, dried fruit, raw unsweetened shredded coconut, seeds (definitely add a tablespoon of chia, ground flax, hemp seeds, sunflower and/or pumpkin seeds. If you do you may need a little extra liquid, because those will absorb more), berries, bananas or even nut butter.
Give it a stir, pack it into a jar, then let the jar sit overnight in the refrigerator.
In the morning, top with fresh ingredients -- fruits, granola, honey, a dollop of peanut butter -- or simply take the whole jar for the road!!
Another Recipe Option:
Use 1 can full fat organic coconut milk.
Pour into bowl with 1/3 cup chia seeds, vanilla, cinnamon, berries if you'd like, and any of the other above things I listed for taste, crunch, and texture. Add any desired sweetener to taste; stevia, raw honey, or maple syrup. Stir and soak for several hours in the fridge. Stir after soaking, and later when you're ready to eat it add any extra nuts or a banana on top.
Play around with different mixtures. It's fun to try different ones but my WHOLE aim with choosing these for you is that it's EASY to make in advance and then you just have it ready to go! Yes, in a jar you can take with you!!
