Kitchen Tools You’ll Need
- Mixing bowl
- Baking pan
- Spoon or spatula
- Measuring cups and spoons
Ingredients
- 57 grams butter, melted (1/4 cup) (adds richness and moisture)
- 65 grams peanut butter (1/4 cup) (provides creaminess and nutty flavor)
- 120 grams honey (1/2 cup) (contributes sweetness and stickiness)
- 120 grams sourdough discard (1/2 cup) (adds subtle tang and moisture)
- 5 grams vanilla extract (1 teaspoon) (enhances overall flavor)
- 55 grams brown sugar (1/4 cup) (adds sweetness and depth)
- 360 grams rolled oats (4 cups) (forms the base and bulk of the bars)
- 3 grams salt (1/2 teaspoon) (balances sweetness)

How to Make Sourdough Granola Bars
Step 1. Begin by melting the butter in a mixing bowl. This process allows the butter to incorporate smoothly into the other ingredients. You want it fully liquefied, which can be checked when it appears clear and uniformly liquid without any solid chunks.
Step 2. After the butter has melted, add the peanut butter to the bowl. Use a spatula to mix them together until they’re well combined. Look for a creamy consistency, which ensures that both flavors intermingle effectively.
Step 3. Now, drizzle in the honey and the sourdough discard into the bowl. Stir the mixture until the wet ingredients are fully combined. This creates a cohesive base mixture, with a smooth and slightly runny consistency.
Step 4. Next, incorporate the vanilla extract and brown sugar into the mixture. Blend them in until the brown sugar is dissolved and the mixture is smooth again. You should have a sweet, fragrant base with a hint of caramel from the brown sugar.
Step 5. In another bowl, combine the rolled oats and salt. Mix these dry ingredients thoroughly to ensure the salt is evenly distributed throughout the oats. This step is essential for achieving balanced flavor in the final product.
Step 6. Gradually mix the dry oat mixture into the wet ingredients. Stir gently but thoroughly, ensuring that all of the oats are coated. The mixture should become thicker and more cohesive as oats absorb the moisture.
Step 7. If you’re choosing to add chocolate chips, fold them in gently at this point. This adds delightful bursts of sweetness and richness in every bite. Ensure they are evenly distributed throughout the mixture for consistent flavor.
Step 8. Grease a baking pan and transfer the mixture into it. Press it down firmly using a spatula or your hands, ensuring it’s compact. This is important for holding the bars together once they’re baked.
Step 9. Place the pan in the oven and bake until the edges begin to turn a light golden brown. You want to keep an eye on it, as this color change indicates that the granola bars are firming up.
Step 10. Once baked, remove the pan from the oven and allow it to cool completely. This cooling period is crucial, as it helps the bars set properly so they hold together when cut.

Serving Suggestions
These granola bars are incredibly versatile. They make a perfect grab-and-go breakfast, offering nutrition and sustained energy for busy mornings. They can also serve as a satisfying snack for both adults and kids during busy afternoons or family meals. Feel free to enjoy them straight from the fridge for a refreshing treat, or crumble them over yogurt for a quick parfait. The best part is that they store well, making them an excellent option for meal prep.
Pro Tips for Best Results
- Ensure the butter is fully melted to integrate smoothly with the other wet ingredients.
- Pack the mixture tightly in the pan to prevent the bars from crumbling when cut.
- Let the bars cool completely before slicing to ensure they hold their shape.
- Use the same ratio of oats and sweeteners for consistency in texture and flavor.
- If using chocolate chips, fold them in after combining wet and dry ingredients to prevent them from melting too much.
- Adjust the sweetness by reducing sugar if desired, but be mindful of the consistency.
Common Mistakes to Avoid
- Not measuring ingredients accurately: This can throw off the texture and flavor. Use a kitchen scale or measuring cups for precision.
- Using un-melted butter or peanut butter: This can lead to uneven mixing. Always melt them first for a smooth combination.
- Not pressing the mixture firmly into the pan: If it’s loosely packed, the bars may crumble when cut. Press down firmly for better cohesion.
- Skipping the cooling step: Cutting the bars too soon can cause them to fall apart. Allow them to cool completely for best results.
- Baking for too long: Overbaking can make bars dry. Look for just a light golden edge for a chewy texture.
- Failing to store properly: Keeping them in a sealed container is key to maintaining freshness. Use an airtight container to avoid staleness.
Variations & Substitutions
Consider adding nuts, seeds, or dried fruits for extra flavor and texture. If you wish to reduce sweetness, consider cutting back on honey or chocolate chips slightly. You can also adjust the nut butter to a different variety, like almond or cashew for a different taste, keeping in mind it may alter the flavor slightly.
Storage & Reheating
These granola bars can be stored at room temperature in an airtight container for up to a week. For longer storage, keep them in the refrigerator where they will last for up to two weeks. They can also be frozen for up to three months, wrapped individually for convenience. When ready to enjoy, let them thaw at room temperature or pop them in the microwave for a few seconds to restore some softness while avoiding excess moisture.
