Chewy Sourdough Granola Bars

Ingredients & Substitutions

  • Oats: This recipe calls for rolled oats. Quick oats are too thin and won’t work well for this recipe. The texture of quick oats deteriorates as they cook.
  • Peanut Butter: Use your favorite creamy nut butter, such as peanut butter, cashew, or almond. If your peanut butter is firm, heat it up in the microwave for easy mixing. 
  • Honey: Adds just the right amount of sweetness and helps hold the granola bars together. If you prefer, you can use maple syrup instead, but they don’t hold up as well when made with it.
  • Butter: I used melted butter (unsalted), but you can use coconut oil for a non-dairy option. 
  • Sourdough Discard: Sourdough discard or active sourdough starter can be used for this recipe, just be sure to use the same amount in grams. 
  • Mix-ins: My kids and I love adding mini chocolate chips for a little extra crunch and sweetness, but you can get as creative as you want. You can mix in chopped nuts, dried fruit, sweet spices, or any favorite option. There are so many fun flavor combinations to play with.

How to Store

To store chewy sourdough granola bars properly, keep them in an airtight container, zip-top bag, or wrap them tightly in beeswax or plastic wrap. At room temperature, they will stay fresh for about 3 to 4 days. For longer storage, refrigeration is recommended, where they can last up to 7 to 10 days. If you want to store them even longer, you can freeze the bars by wrapping each one individually in plastic wrap or parchment paper, then placing them in a freezer-safe bag or container. Frozen bars will keep well for up to 2 to 3 months. When ready to eat, thaw the bars at room temperature or in the refrigerator until they soften enough to enjoy. This storage method helps maintain the bars’ chewy texture and freshness while preventing them from drying out or becoming crumbly.
