- Reduce your kitchen waste: No need to toss your sourdough discard or ripe bananas. Make them into these delicious cookies instead!

🥣 Ingredients needed
The complete list of ingredients and amounts can be found in the recipe card below. This is just an overview of the ingredients and any extra information about them that you may need.
For the cookies, you will need:
- All purpose flour
- Ripe bananas: I used bananas that were spotty. I recommend that you use bananas that are at least spotty, if they are too yellow they won’t be sweet enough for the cookies. If you are using extremely dark bananas that are super ripe, you may want to add an extra tablespoon of flour since they will have a little extra liquid.
- Sourdough discard: If you are new to sourdough baking then be sure to read my post on how to make sourdough starter with blueberries.
- Sugar
- Butter: You’ll want to soften your butter to room temperature.
- Egg
- Baking soda
- Salt
- Vanilla extract
- Cinnamon
For the glaze:
- Powdered sugar
- Milk
🍫Variations
- You can add in some chocolate chips or nuts if you like.
- I prefer the cookies with the glaze but it is optional.
⏲️ Recipe instructions (step by step guide)
Preheat your oven to 350° F. Mash your bananas with a fork and set aside.
Next, cream together your sugar, butter (room temperature), and vanilla extract (image 1).
Add the remaining ingredients and mix until well combined (image 2). Do not over mix.
Use a large cookie scoop (the dough will be sticky) to drop cookies on your baking sheet (image 3).
Bake for 13 to 16 minutes or until the edges are golden. Let the cookies cool.
Whisk together the powdered sugar and milk. Drizzle over the cookies once you are ready to serve them (image 4).
👩🏻🍳 Tips
- The glaze is optional but I recommend adding the glaze if you want a sweeter cookie. My kids actually liked the cookies better without the glaze.
- If you have very ripe and very dark bananas, you may want to add an extra tablespoon of flour as the bananas may have extra moisture from being so ripe. I prefer using bananas that are spotty.
🥡 How to store leftovers
You can store unglazed cookies at room temperature for up to four days after making. I recommend glazing right before you serve the cookies.

These cookies are so pillowy and delicious! I only had one ripe banana on hand so instead of 1/2 cup sugar, I did 1/4 cup sugar and 1/4 maple syrup, and 1 3/4 cup flour. Highly recommend!
