Sourdough Granola Bars: An Easy Discard Recipe for Busy Days

Some recipes happen because I’m trying to use up sourdough discard. Others happen because one of my kids is looking for a favorite snack.

These sourdough granola bars were inspired by my daughter.

She loves having granola bars on hand for a quick breakfast on busy mornings or an easy snack during the day. After buying them for a while, I started thinking, what if I just made them myself? Better yet, what if I could clean up the ingredients a little and put some of my sourdough discard to good use at the same time?

After a little experimenting, these sourdough granola bars quickly became a favorite. I’ve made them multiple times now because she keeps asking for them. They’re simple to make, made with ingredients I usually have on hand, and they disappear quickly every time I bake a batch.

Best of all, they’re an easy way to use sourdough discard while creating a snack my family genuinely enjoys.

Tips for the Best Sourdough Granola Bars

Press the Mixture Firmly

After transferring the mixture to the pan, use a piece of parchment paper to press everything down firmly. This helps the bars hold together once they’ve cooled.

Let Them Cool Completely

It can be tempting to cut into them right away, but allowing them to cool first helps them set properly.

Chill Before Slicing

Once cooled, place the pan in the refrigerator for about an hour before cutting. This helps the bars firm up and creates cleaner slices.

How to Store Homemade Granola Bars

Once sliced, store the bars in an airtight container.

You can also wrap individual bars for quick grab-and-go breakfasts, homeschool snack breaks, church nights, or busy afternoons when everyone suddenly decides they’re hungry at the same time.
