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.

Ingredients

Sourdough breakfast cookies ingredients.
  • Quick-cooking oats (or old-fashioned)
  • Ripe banana
  • Egg
  • Cinnamon
  • Salt
  • Ground flaxseed/flaxseed meal
  • Maple syrup (optional)
  • Peanut butter

See the recipe card for quantities.

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!

See these sourdough oatmeal cookies on my website if you are looking for a sweeter, more dessert-like oatmeal cookie!

Equipment

  • Mixing bowl
  • Cookie scoop (this is my set-- I used the largest one for these cookies because I like to give my son ½ of a cookie at a time)
  • Cookie sheet

Storage

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!

FAQ

Do I need to use instant oats?

No! Feel free to use regular rolled oats for this recipe. The peanut butter, bananas, and sourdough discard are good binders. I just add the egg for a little more protein.

Can I make these vegan breakfast cookies?

Yes! Just leave out the egg. 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.
