Kitchen Tools You’ll Need
- Medium saucepan
- Baking dish (8×8 inch recommended)
- Mixing bowl
- Spatula or wooden spoon
- Parchment paper (optional)
Ingredients
- 1/4 cup butter (adds richness and moisture)
- 1/4 cup peanut butter (provides flavor and binds ingredients)
- 1/2 cup honey (adds sweetness and sticky texture)
- 1/2 tsp salt (enhances overall flavor)
- 1/2 cup sourdough discard (flat, runny) (contributes moisture and texture)
- 1 tsp vanilla (adds warmth and depth of flavor)
- 1/4 cup brown sugar (light or dark) (adds sweetness and a hint of caramel)
- 3.5 cups rolled oats (forms the base and provides chewiness)
- 1 cup miniature chocolate chips (adds sweetness and visual appeal)
- 1/2 cup chopped peanuts (optional) (adds crunch and nuttiness)

How to Make Sourdough Discard Granola Bars (Chocolate Peanut Butter)
Step 1. Begin by melting the butter and peanut butter together in a medium saucepan over low heat. Stir gently until both are entirely combined and smooth. This step is crucial to ensure that your mixture blends well and feels creamy. You’ll want to watch for a slight bubbling, indicating that the butters are warmed through.
Step 2. Remove the saucepan from heat and add the honey, salt, sourdough discard, vanilla, and brown sugar. Stir everything together until the mixture is smooth and cohesive. The honey will bring a sticky texture, and the brown sugar will add a touch of sweetness. Mixing thoroughly now will help integrate these flavors into the batter.
Step 3. In a separate mixing bowl, combine the rolled oats with the chocolate chips and chopped peanuts if you are using them. This dry mixture is essential to combine the dry elements of the recipe evenly. Make sure the ingredients are well distributed, which will promote an even taste in the final bars.
Step 4. Pour the wet mixture from the saucepan into the bowl with the dry ingredients. Stir well until everything is evenly coated and you can no longer see any dry oats. This ensures that every bite of the granola bars is flavorful and cohesive. The mixture should feel somewhat sticky as it starts to come together.
Step 5. Prepare a baking dish by lining it with parchment paper or greasing it lightly. Transfer the granola mixture into the dish and spread it out evenly. Use a spatula or your hands to press it firmly into the corners and flatten the top. Pressing it down well helps maintain the bar shape when it sets, so don’t skip this step.
Step 6. Allow the granola bars to cool completely in the dish at room temperature until they are set, which should take about one hour. Once fully cooled, they will firm up and be easier to cut. Check the edges for a slight firmness, which indicates they are ready to be sliced.

Serving Suggestions
These granola bars are wonderfully versatile. You can serve them as a quick breakfast option, paired with a cup of coffee or tea for a wholesome start to the day. They are perfect as a midday snack, providing sustained energy during busy work hours. Additionally, they work well in lunchboxes for kids and adults alike, making them a great choice for family meals. If you have any leftovers, enjoy them as a convenient grab-and-go treat throughout the week.
Pro Tips for Best Results
- Make sure to press the granola mixture firmly into the dish to create compact bars that hold together well.
- Use a sharp knife to cut the bars after they have cooled completely for cleaner edges.
- Store the bars in an airtight container to keep them fresh.
- Experiment with the mix-ins, such as dried fruits or seeds, to personalize your flavor.
- For added sweetness, consider drizzling a bit of extra honey over the top after baking.
- Allowing the bars to chill in the fridge for a short time after cutting can enhance their firmness.
Common Mistakes to Avoid
- Not pressing the mixture firmly: If you don’t pack the mixture tightly into the baking dish, the bars may crumble apart. To avoid this, use your hands or a spatula to compress it evenly.
- Using overly warm mixtures: If the mixture is too hot when combined with the dry ingredients, it can melt the chocolate chips. Let it cool slightly before mixing to maintain their shape.
- Skipping the cooling step: If you cut the bars before they are fully cooled, they won’t hold their shape. Allow them to set completely at room temperature for the best results.
- Not measuring ingredients accurately: Inaccurate measurements can affect the texture of your granola bars. Use measuring cups and spoons to ensure you achieve the right balance.
- Leaving out the salt: Salt enhances flavor, and skipping it can lead to bland bars. Even a small amount can make a significant difference.
- Ignoring the ingredient ratios: Altering the quantities of oats to wet ingredients can lead to bars that are either too dry or too soggy. Stick to the recipe for a good balance.
Variations & Substitutions
For a twist on the recipe, consider replacing some of the chocolate chips with dried fruits like cranberries or raisins. Also, you can try adding different nut butters, like almond or cashew, to change up the flavor profile. For a crunchy texture, experiment with seeds like sunflower or pumpkin seeds instead of peanuts.
Storage & Reheating
To store your granola bars, keep them in an airtight container at room temperature for up to one week. If you need longer storage, you can refrigerate them for freshness, where they will last about two weeks. If you prefer to freeze them, wrap individual bars tightly and store them in a freezer-safe bag or container. For reheating, just let them sit at room temperature for a few minutes, which will help retain their texture.
