Cook the Oats: In a medium saucepan, bring the warm water to a simmer. Add the oat flakes, stir, and cook for 5-7 minutes until the oats absorb the water and become creamy. Stir occasionally to avoid sticking.
Mash the Bananas: While the oats are cooking, peel the bananas and mash them in a bowl using a fork until smooth. You can also leave some small chunks for added texture.
Combine and Flavor: Once the oats are cooked, stir in the mashed bananas and vanilla extract. Mix well and let it cook for an additional 2-3 minutes over low heat to blend the flavors together.
Serve: Remove from heat, transfer to bowls, and enjoy this simple, wholesome oatmeal for breakfast.
