In a mixing bowl, mash the ripe banana with a fork until smooth.
Add the rolled oats, dairy-free milk, chia seeds, cacao powder, maple syrup, peanut butter, vanilla extract, almond extract, and a sprinkle of cinnamon into the bowl with the mashed banana. Stir until everything is well combined.
Transfer the mixture into an airtight jar or container. Make sure to leave some space at the top, as the oats will expand as they absorb the liquid.
Seal the jar tightly and refrigerate overnight.
In the morning, give your oats a good stir. You can add a splash more of dairy-free milk if you prefer a thinner consistency. Top with extra banana slices, a drizzle of peanut butter, or even a handful of nuts for added crunch. Enjoy your nutritious breakfast!
