✔ Don’t skip the chia seeds – They help thicken the oatmeal and add a boost of fiber and healthy fats.
✔ Let it sit before baking – After mixing everything, give it 5 minutes to let the oats and chia start soaking up the liquid. It helps with texture.
✔ Add toppings after baking – A drizzle of almond butter, a spoonful of Greek yogurt, or a sprinkle of nuts takes it over the top.
