Ingredients You’ll Need
- ⅔ cup peanut butter: Choose creamy or chunky based on your texture preference. Peanut butter adds protein and rich flavor, making these bars satisfying.
- ½ cup butter or margarine, melted: This provides richness and helps bind the ingredients together. If you prefer, use coconut oil as a healthier alternative.
- ½ cup brown sugar: Adds sweetness and moisture. Coconut sugar can serve as a great substitute if you’re looking for a less processed option.
- ½ cup corn syrup: Helps keep the bars chewy and prevents them from becoming too dry. Honey or agave syrup can replace it for a natural alternative.
- 2 teaspoons vanilla: A splash of pure vanilla extract enhances the overall flavor. Make sure to use pure vanilla for the best taste.
- ½ cup shredded coconut: Adds a tropical twist and texture. You can use unsweetened or sweetened coconut, depending on your preference.
- ½ cup raisins: These provide natural sweetness and chewiness. Feel free to substitute with dried cranberries or chopped dates.
- ⅓ cup wheat bran: A great source of fiber, it adds a healthy boost. If you don’t have wheat bran, ground flaxseed is a good alternative.
- ½ cup mini chocolate chips: Sweet and melty, they bring a delightful treat to each bite. Use dark chocolate chips for a healthier option.
- 3 cups large flake oatmeal: The heart of these granola bars, large flakes give them structure. Quick oats can work, but may make them a bit denser.
How to Make Peanut Butter Granola Bars
- Preheat the Oven: Start by preheating your oven to 350℉. This ensures even baking, resulting in perfectly chewy bars.
- Mix the Wet Ingredients: In a large mixing bowl, combine ⅔ cup peanut butter, ½ cup melted butter, ½ cup brown sugar, and ½ cup corn syrup. Stir until the mixture is smooth and well-blended.
- Add Vanilla: Pour in 2 teaspoons of vanilla extract to enhance the flavor further, stirring it into the peanut butter mixture.
- Combine the Dry Ingredients: Next, add ½ cup shredded coconut, ½ cup raisins, ⅓ cup wheat bran, and 3 cups large flake oatmeal into the wet mixture. Mix until everything is fully combined and evenly coated.
- Fold in Chocolate Chips: Gently fold in ½ cup mini chocolate chips, ensuring they’re evenly distributed throughout the mixture for that perfect chocolatey bite.
- Prepare the Baking Pan: Line a 9×13 inch baking pan with parchment paper or foil, and lightly spray it with non-stick spray to prevent sticking.
- Spread the Mixture: Pour the mixture into the prepared pan, spreading it evenly with a spatula to ensure all corners are filled.
- Bake: Place the pan in the oven and bake for 15 to 25 minutes, or until the top turns a light golden brown and is fragrant. Keep an eye on it to avoid overbaking.
- Cool & Slice: Once done, remove from the oven and let it cool completely in the pan. Once cooled, lift the bars out using the parchment paper and slice them into squares or rectangles.
Storing & Reheating
To store your Peanut Butter Granola Bars, place them in an airtight container at room temperature for up to a week. For longer storage, refrigerate them in the same container where they will last for about two weeks. If you choose to freeze them, wrap each bar individually in plastic wrap and then place them in a freezer-safe bag. They can stay fresh for up to three months. When you want to enjoy one, simply thaw it at room temperature for a bit, or microwave it for about 10-15 seconds to restore some of the soft texture.
Chef’s Helpful Tips
- To avoid crumbly bars, make sure to mix the wet ingredients thoroughly before adding the dry. This ensures everything binds nicely.
- If your mixture is too dry, add a bit more peanut butter or a splash of milk to help moisten it without changing the flavor dramatically.
- Pay attention to baking times; every oven is different. Start checking around 15 minutes to prevent overbaking.
- Want to switch things up? Add nuts like almonds or walnuts for a textural twist.
- To make these breakfast bars heartier, add protein powder to boost nutrition.

Recipe FAQs
Can I use natural peanut butter for these granola bars?
Absolutely! Natural peanut butter can be used, but it may change the texture slightly. Since it contains oil that can separate, stir it well before using. You may need to adjust the amount of sweetener, as natural peanut butters can have a more pronounced nutty flavor.
How can I make these bars gluten-free?
To make gluten-free Peanut Butter Granola Bars, simply ensure you use certified gluten-free oats and replace any other ingredients containing gluten with gluten-free alternatives. Many brands offer gluten-free brown sugar and corn syrup.
What is the best way to cut these granola bars?
To cut evenly, allow the bars to cool completely. Use a sharp knife and press down firmly rather than sawing through the mixture. Cleaning the knife between cuts helps maintain clean edges.
Can I modify the sweetness in this recipe?
Definitely! You can reduce the amount of brown sugar or substitute it with a sweeter natural alternative like pure maple syrup or agave to adjust the sweetness to your taste preference. Remember to balance it with the wet ingredients so the consistency stays right.
