Steps

  1. Heat the oven until it is ready for baking and line a small baking tray with parchment.
  2. Mix the mashed banana, brown sugar, soy milk, and oil in a bowl.
  3. Stir in the oats, baking powder, and salt until evenly combined. Let the mixture stand for 5 minutes so the oats absorb some moisture.
  4. Shape into one thick cookie on the tray and gently flatten it.
  5. Bake for 14–18 minutes, until the edges look set and lightly golden. Cool on the tray for 5 minutes before eating.

Tips for One-Banana Oatmeal Brown Sugar Cookie

  • A very ripe banana gives the cookie more sweetness and a stronger banana flavor.
  • For a chewier center, take it out when the middle still looks slightly soft; it firms as it cools.
  • Use a small bowl and fork to mash and mix everything with minimal cleanup.

Drink pairing

A cup of black tea
Its gentle tannins balance the cookie’s banana sweetness and brown sugar notes.

0% option: A cup of unsweetened black tea

Storage

Store cooled cookie in an airtight container in the refrigerator for up to 3–4 days. Reheat until steaming hot if you prefer it warm.

Frequently asked questions

How do I know when the cookie is done?

The edge should look set and lightly golden, while the center may remain a little soft; it firms as it cools.

Can I prepare the mixture ahead?

You can mix it a few hours ahead and keep it covered in the refrigerator; shape and bake it when ready.

Why did my cookie spread or turn out too soft?

Banana size and ripeness affect moisture. If the mixture looks loose, stir in a teaspoon of oats and let it stand briefly.
