Delicious Sourdough Granola Bars (Nutty & Super Crunchy!)
The first time I discovered the magic of sourdough discard, I was deep into my sourdough baking phase.
After weeks of perfecting my loaves, I found myself with an ever-growing stash of discard. It felt wasteful to throw it away, so I started experimenting with creative ways to use it.

The result? Chewy, flavorful bars filled with crunchy nuts, sweet dried fruit, and just the right touch of tangy richness.

They quickly became a household favorite—perfect for busy mornings, afternoon snacks, or even a post-workout pick-me-up.

How to Make Sourdough Granola Bars
- Preheat and toast: Preheat oven to 350°F (175°C). Line an 8×8-inch baking dish with parchment paper. Spread oats and nuts on a baking sheet and toast for 5-7 minutes until fragrant.
- Mix dry ingredients: In a large bowl, combine the toasted oats, nuts, dried fruit, salt, and cinnamon.
- Combine wet ingredients: In another bowl, whisk together sourdough discard, nut butter, honey, coconut oil, vanilla, and egg until smooth.
- Mix everything: Pour the wet mixture into the dry ingredients, stirring until fully incorporated.
- Press into pan: Transfer mixture to the prepared baking dish, spreading it out evenly and pressing firmly with a spatula.
- Bake: Bake for 25 minutes or until golden around the edges.
- Cool completely: Let the bars cool in the pan before cutting. This ensures they hold their shape!

Expert Tips for Perfect Granola Bars
- Pack the mixture tightly: Pressing the mixture firmly into the pan prevents crumbly bars.
- Let them fully cool: Cutting too early may result in messy, broken bars.
- Customize the flavors: Try adding chocolate chips, shredded coconut, or a dash of cinnamon.
- Store properly: Keep in an airtight container at room temperature for up to a week, or refrigerate for longer freshness.
- For softer bars: Use a touch more nut butter or honey to increase moisture content.
