Ingredients

  • 2 cups rolled oats
  • ½ cup sourdough discard unfed, 100% hydration
  • ¼ cup honey or maple syrup
  • ¼ cup melted coconut oil or butter
  • 1 tsp vanilla extract
  • ½ tsp cinnamon
  • ¼ tsp salt
  • ½ cup chopped nuts almonds, pecans, walnuts, or a mix
  • ¼ cup seeds pumpkin, sunflower, or flax
  • ¼ cup mini chocolate chips or dried fruit
  • 1 egg optional, helps bind the bars

Instructions

1. Preheat & Prep

  • Preheat your oven to 325°F (160°C). Line an 8x8-inch square baking pan with parchment paper, leaving some overhang for easy removal.

2. Mix Wet Ingredients

  • In a large mixing bowl, combine the sourdough discard, honey or maple syrup, melted coconut oil (or butter), vanilla extract, cinnamon, and salt. Whisk until smooth and well combined.

3. Add Dry Ingredients

  • Stir in the rolled oats, chopped nuts, seeds, and chocolate chips or dried fruit. If using an egg, add it in last and mix until everything is evenly incorporated.

4. Press & Bake

  • Transfer the mixture to your prepared pan and press it down firmly and evenly with a spatula or your hands. Pressing well is key to helping the bars stick together. Bake for 25–30 minutes, or until the edges turn golden brown.

5. Cool & Slice

  • Let the bars cool completely in the pan—this step is important. They’ll firm up as they cool, making them much easier to slice. Once cool, lift the bars out using the parchment overhang and slice into 8 to 12 bars.

6. Store & Enjoy

  • Store your sourdough granola bars in an airtight container at room temperature for up to 1 week, or freeze them for longer shelf life. They thaw beautifully!

Notes

  • Want crunchier bars? Bake for an extra 5 minutes, but keep an eye on the edges to prevent burning.
  • For softer bars, reduce the baking time slightly
  • Add-ins ideas: shredded coconut, cacao nibs, dried cherries, chopped dates, or even a swirl of almond butter.
  • For extra binding power, especially if not using an egg, you can add 1–2 tablespoons of nut butter or mashed banana.
