Peel the ripe banana and break it into a few chunks.
Place the banana chunks, frozen strawberries, and chia seeds into a blender.
Pour in the oat milk.
If you prefer a sweeter smoothie, you can add a drizzle of maple syrup at this point. Start with a small amount, blend, and taste before adding more if needed.
Start blending at low speed and gradually increase it to high.
Blend for about 1-2 minutes or until all the ingredients are well combined and the smoothie reaches your desired consistency. If it's too thick, you can add more oat milk to thin it out.
Pour the smoothie into a glass or a portable container. You can sprinkle some extra chia seeds or roasted oats on top.
Notes
If you prefer a colder smoothie, use ice cubes while blending. If you like it at room temperature, skip the ice.Adjust ingredients to your taste preferences. If it's too thick, add more liquid; if it's too thin, add more frozen fruit.
