These sourdough discard chocolate chip granola bars are a deliciously healthy snack, packed with wholesome ingredients and none of the junk. Perfectly balanced for a guilt-free treat, they’re the ideal blend of crunchy, chewy, and chocolatey goodness!

These sourdough discard chocolate chip granola bars are the perfect healthy alternative to store-bought snacks, made without any of the artificial ingredients or preservatives you’ll find in pre-packaged options. With a blend of wholesome ingredients, these bars offer a satisfying and nourishing treat that won’t leave you feeling guilty.

The secret ingredient here is sourdough starter discard, which not only gives these bars a deliciously unique flavor but also comes with several health benefits. Sourdough starter contains live cultures, promoting healthy gut bacteria, which can improve digestion and enhance the immune system. The fermentation process also breaks down phytic acid, making the minerals in the grains more bioavailable. Plus, sourdough has a lower glycemic index than many other grains, making it a better choice for balancing blood sugar levels.

These granola bars are incredibly easy to make, taking less than 30 minutes from start to finish. They’re ideal for meal prepping, making them a convenient and nutritious snack that you can grab on the go. Whether you’re looking for a healthy breakfast or a mid-afternoon pick-me-up, these bars provide the perfect combination of protein, fiber, and healthy fats to keep you energized throughout the day.

ingredients

Sourdough discard – Adds a subtle tangy flavor, can help with digestion if fermented, and acts as a mild binder. If using discard, it’s a great way to reduce waste while adding complexity to the bars.

Rolled oats – The base of the bars! They add texture, fiber, and a hearty chew while helping absorb moisture from the wet ingredients.

Honey – A natural sweetener that also acts as a binder, keeping the bars from falling apart while adding a slight chewiness.

Peanut butter – Works as a binder to hold everything together, adds creaminess, boosts protein and healthy fats, and provides a rich, nutty flavor.

Butter – Adds richness, helps bind ingredients, improves texture (making the bars soft or slightly crisp), and extends shelf life.

Brown sugar – Provides sweetness and a slight molasses flavor while helping with moisture retention and chewiness.

Vanilla extract – Adds a warm, sweet depth of flavor that complements the honey, peanut butter, and brown sugar.

Salt – Enhances and balances the sweetness, bringing out the flavors of the other ingredients. Even a small pinch makes a big difference.

Recipe

Preheat your oven to 350°F (175°C). Lightly grease a 9×9-inch baking pan or line it with parchment paper for easy removal.

In a medium saucepan over low heat, or in a microwave, melt the butter and peanut butter together, stirring frequently until smooth and fully combined. This step helps the mixture blend evenly with the other ingredients, creating a soft and chewy texture in the granola bars.

To the warm butter mixture, add brown sugar, vanilla extract, salt, honey, and sourdough starter. Stir well until the brown sugar is dissolved, and everything is fully incorporated.

Gradually fold in the rolled oats, ensuring they are evenly coated with the wet mixture. This step is crucial for binding the bars together and giving them that signature chewy texture.

Let the mixture cool slightly for a couple of minutes before gently stirring in the chocolate chips. If the mixture is too hot, the chocolate may melt rather than staying in solid chunks, so letting it cool just a bit helps maintain some texture.

Transfer the granola mixture to your prepared 9×9-inch baking pan. Using a spatula or the back of a spoon, firmly press it down into an even layer. Pressing it well ensures the bars hold together once baked.

Place the pan in the preheated oven and bake for 20-25 minutes, or until the edges are lightly golden. The longer bake time will result in firmer, crispier bars, while a shorter bake will keep them softer and chewier.

Once baked, remove from the oven and allow the bars to cool in the pan for at least 30 minutes before slicing. This helps them firm up and prevents crumbling. Once completely cooled, cut into squares or bars and enjoy!


How to Store Your Granola Bars

To keep your homemade granola bars fresh and delicious, proper storage is key. If you plan to enjoy them within a few days, wrap each bar individually in wax paper and store them in an airtight container on the counter for up to 5 days. This prevents them from drying out while keeping them easy to grab for a quick snack.

For longer storage, place the individually wrapped bars in a zip-top freezer bag or airtight container and freeze them for up to 3 months. When ready to eat, simply let a bar sit at room temperature for about 10-15 minutes, or enjoy it straight from the freezer for a firmer, chewier texture. Freezing not only extends their shelf life but also helps maintain their texture and flavor.

Ingredients

  • 1/2 cup sourdough starter discard

  • 4 cups rolled oats

  • 1/2 cup honey

  • 1/4 cup peanut butter

  • 1/4 cup butter

  • 1/4 cup brown sugar

  • 1 cup chocolate chips

  • 1 teaspoon vanilla extract

  • Pinch of salt

Directions

  • Preheat your oven to 350°F (175°C). Lightly grease a 9×9-inch baking pan or line it with parchment paper for easy removal.
  • In a medium saucepan over low heat, or in a microwave, melt the butter and peanut butter together, stirring frequently until smooth and fully combined. This step helps the mixture blend evenly with the other ingredients, creating a soft and chewy texture in the granola bars.
  • To the warm butter mixture, add brown sugar, vanilla extract, salt, honey, and sourdough starter. Stir well until the brown sugar is dissolved, and everything is fully incorporated.
  • Gradually fold in the rolled oats, ensuring they are evenly coated with the wet mixture. This step is crucial for binding the bars together and giving them that signature chewy texture.
  • Let the mixture cool slightly for a couple of minutes before gently stirring in the chocolate chips. If the mixture is too hot, the chocolate may melt rather than staying in solid chunks, so letting it cool just a bit helps maintain some texture.
  • Transfer the granola mixture to your prepared 9×9-inch baking pan. Using a spatula or the back of a spoon, firmly press it down into an even layer. Pressing it well ensures the bars hold together once baked.

  • Once baked, remove from the oven and allow the bars to cool in the pan for at least 30 minutes before slicing. This helps them firm up and prevents crumbling. Once completely cooled, cut into squares or bars and enjoy!

Notes

  • If you prefer a crispier texture, bake the bars for the full 25 minutes and let them cool completely before slicing. You can also toss in chopped nuts or toasted coconut for added crunch
  • Swap peanut butter for almond butter, cashew butter, or sunflower seed butter if you need a nut-free alternative
  • Maple syrup can also replace honey for a slightly different sweetness and a vegan-friendly version
  • If using sourdough starter discard, you can mix the wet ingredients the night before and let them sit in the fridge, this allows the grains to soak, making the bars easier to digest while developing a deeper flavor
