How to Make Sourdough Discard Granola Bars with Peanut Butter, Chocolate Chips, and Oats Recipe

Step 1: Preheat and Prepare

Start by preheating your oven to 325 degrees Fahrenheit. This moderate temperature ensures the granola bars cook evenly without burning, keeping the peanut butter and honey flavors nicely melded.

Step 2: Melt the Butter and Peanut Butter

In a microwave-safe bowl, warm the butter and peanut butter together for about 30 seconds until melted and smooth. This warm, silky combo is what helps the bars hold their shape and gives that lovely chewy texture you’re after in every bite.

Step 3: Mix in the Wet Ingredients

Into the melted mixture, stir in the honey, sourdough discard, and vanilla extract. Combining these early on ensures the tangy sourdough and sweet honey become one harmonious flavor base for your bars.

Step 4: Add the Dry Ingredients

Next, fold in the brown sugar, rolled oats, and salt. This is where the bulk and heartiness happen. After gently mixing these pantry staples, fold in the mini chocolate chips. Their melty sweetness perfectly offsets the nuttiness and tang.

Step 5: Press the Mixture into the Pan

Line a 9×9-inch pan with parchment paper and dump in your granola mixture. Use another piece of parchment to firmly press everything down into an even, compact layer. This pressing step is crucial to make sure your bars hold together well once baked—don’t rush it!

Step 6: Bake the Bars

Pop the pan in the oven and bake for 25 minutes at 325 degrees Fahrenheit. You want them cooked through but still chewy in the center, so watch for golden edges forming.

Step 7: Cool and Chill

Once baked, let the granola bars cool completely in the pan. After cooling, cover and chill them in the fridge for at least one hour, though two hours is ideal. This resting time helps the bars set perfectly so you can slice without crumbling.

Step 8: Slice and Store

After chilling, lift the granola from the pan using the parchment, then cut into 12 equal bars. Wrap individually for on-the-go snacking or store in an airtight container to keep them fresh and chewy.

Garnishes

Want to dress up these bars a little? Sprinkle with a handful of toasted nuts or a drizzle of melted dark chocolate for extra decadence. A light dusting of sea salt on top before baking also elevates the flavor balance beautifully.

Side Dishes

Pair these granola bars with a creamy yogurt or fresh fruit for a balanced breakfast or snack. A smear of almond butter on the side or a cold glass of milk makes for a wholesome accompaniment as well.

Creative Ways to Present

Wrap each bar in colorful parchment or beeswax wraps to give a rustic, homemade gift vibe. You can also cut the bars into bite-sized pieces for a granola bar “trail mix” board perfect for parties or afternoon pick-me-ups.

Make Ahead and Storage

Storing Leftovers

Keep any leftover granola bars in an airtight container at room temperature for up to five days. For the best chewy texture, storing them in the fridge is a smart idea, especially in warmer climates.

Freezing

These bars freeze wonderfully! Individually wrap them and place in a freezer-safe bag. They’ll keep for up to two months and thaw quickly at room temperature or in your bag for a convenient snack anytime.

Reheating

If you prefer a warm granola bar, pop one in the microwave for 15–20 seconds. This melts the peanut butter and chocolate chips just a bit, creating a heavenly gooey bite perfect with a cup of coffee or tea.

FAQs

Can I use any nut butter instead of peanut butter?

Absolutely! Almond butter, cashew butter, or even sunflower seed butter work great and bring their own unique flavors. Just make sure it’s smooth to help bind the ingredients well.

Is it necessary to use sourdough discard?

The discard is what gives these granola bars their signature tang and moisture, but you could experiment with yogurt or mashed banana for a slightly different twist if you don’t have discard on hand.

Can I omit the chocolate chips?

Yes, if you’re not a chocolate fan or want to keep things simple, you can leave them out. Consider adding dried fruit, such as cranberries or raisins, for a chewy sweetness instead.

What’s the best way to cut the bars without them crumbling?

Make sure the bars are completely cooled and chilled before slicing. Using a sharp knife and wiping it clean between cuts helps keep the edges neat and prevents crumbling.

Are these granola bars gluten-free?

They can be if you use certified gluten-free rolled oats and ensure your other ingredients are gluten-free. Always check labels if gluten sensitivity is a concern.
