In a sealable mason jar or small container, add the almond milk, Greek yogurt, rolled oats, protein powder, chia seeds, vanilla extract, and mashed ripe banana. Stir thoroughly to combine, making sure all oats are submerged in the mixture. If the mixture seems too thick, add an extra splash of almond milk as needed. This creates a creamy and nutritious base for your overnight oats.

Pick which flavor of overnight oats you'd like to make. For pumpkin spice, stir in pumpkin puree, maple syrup or honey, and pumpkin pie spice. For apple cinnamon, add diced apple, maple syrup or honey, and cinnamon. For peanut butter strawberry, mix in peanut butter, diced strawberries, additional almond milk, maple syrup or honey, and a bit more vanilla extract. For peach coconut, stir in diced peach, cinnamon, and shredded coconut. Mix well to evenly distribute the flavor ingredients throughout the oats. I like to taste the mixture at this stage and adjust the sweetness or spice to my liking.

Place the lid on top of your jar or container to seal it tightly. Refrigerate your overnight oats mixture for at least 6 hours or ideally overnight. The oats will absorb the liquid and flavors as they sit, resulting in a soft and creamy texture. You can store these in the fridge for up to 5 days, making them a perfect make-ahead breakfast option.

When you're ready to serve, give the overnight oats a good stir. If you prefer a looser consistency, add a splash of extra almond milk. Top with your favorite toppings: sliced banana, extra diced apple, chopped pecans, or shredded coconut, depending on the flavor you chose. Enjoy your oats chilled! For extra crunch and flavor, I love adding a sprinkle of chopped pecans or a spoonful of fresh fruit right before eating.
