These nutritious and delicious sourdough breakfast cookies are kid-friendly and picky eater-approved! Filled with protein, fiber, fats, and sweet bananas, you and your family are going to love these.
My toddler is a very picky eater, but loves a good cookie so I naturally started experimenting with ways to combine his love for cookies with a filling, yummy breakfast and this was the result! I add a few tablespoons of mini chocolate chips to them sometimes (pictured) because he loves them so much.

These cookies are perfect for a quick and easy breakfast idea for you or your kiddos! My toddler could eat these all day.

Instructions

Step 1: Preheat oven to 350F. In a medium mixing bowl, mix dry ingredients: oats, cinnamon, salt, and flaxseed meal.

Step 2: To the same bowl, add mashed banana, egg, peanut butter, maple syrup (optional), and sourdough discard.

Step 3: Mix until combined and add chocolate chips to taste (optional).

Step 4: Scoop onto a prepared baking sheet and use a fork to press them flat lightly. Bake for 14-15 minutes. Makes 7 cookies if using a 3Tbsp cookie scoop.
Hint: These cookies will not spread or rise, so it is important to flatten them a bit before baking.

Substitutions
- Oats - Instead of using instant oats, feel free to use regular rolled oats. I just prefer how chewy and soft instant oats are with these. Note: if using rolled oats, you *might* need to add more oats to get the right consistency for scooping. I have not tried this myself, so use your best judgment to mimic the consistency you see in the photos.
- Vegan - The egg in this recipe is not essential, so feel free to omit it if you are vegan.
Variations
- Low-sugar - Easily leave out the maple syrup and chocolate chips and let the sweet bananas be the star of the show!

Store in an airtight container at room temperature or in a refrigerator for 3-5 days or freeze for up to 6 months.
Top tip
Make sure your bananas are super ripe! Lots of brown spots and a very thin peel are indicators that they are ready to be used in this recipe!
