Mash up the two bananas in a bowl and add all the other ingredients together.
Stir well and transfer to a mason jar or a cup with a lid.
Place in the refrigerator overnight.
In the morning, add any toppings like walnuts, bananas, cinnamon, or blueberries.
Hint: All of the foods in this recipe are green on Noom, other than the chia seeds (which are red). If you're trying to budget your red foods, you can omit these.
Feel free to spice this up with any toppings or add-ins of your choice. When I make this for my kids, I put out little topping bowls with sliced bananas, chopped walnuts, dark chocolate chips (on special occasions), and coconut flakes. It's a big hit and very hands-on. This recipe makes three servings, each with 333 calories (273 if you omit the chia seeds). One jar is good in the refrigerator for up to three days.
