Martha Stewart’s Peanut Butter Granola Bars: A Culinary Classic

The scent of peanut butter always takes me back to childhood summer afternoons. My grandmother, a woman who could coax magic from the simplest ingredients, often whipped up peanut butter bars. They weren’t fancy, but they were undeniably comforting, a perfect blend of sweet and salty that fueled countless bike rides and backyard adventures. These Martha Stewart’s Peanut Butter Granola Bars bring back those memories while adding a satisfying crunch and sophisticated touch that elevate them to a truly irresistible treat.

Recipe Overview

• Prep Time: 10 minutes
• Cook Time: 5 minutes
• Total Time: 15 minutes
• Yields: 24 bars
• Dietary Type: Vegetarian

Ingredients

• 4 tablespoons butter, plus more for the pan
• 10 1/2 ounces miniature marshmallows
• 1/2 cup peanut butter
• 8 cups granola cereal

Equipment Needed

• 9-inch square baking pan
• Large saucepan
• Measuring cups and spoons
• Mixing spoon
• Rubber spatula

Instructions

1. First, grease a 9-inch square pan with butter. Set aside. This step is crucial to prevent the bars from sticking, ensuring easy removal and clean cuts later.
2. Measure out 8 cups of granola cereal into a large bowl and set it aside. Having this prepared in advance allows you to quickly incorporate it into the melted marshmallow mixture, preventing the mixture from cooling down and becoming difficult to work with.
3. In a large saucepan, melt 4 tablespoons of butter over medium-low heat. Once the butter is completely melted, add 10 1/2 ounces of miniature marshmallows.
4. Continue to stir the butter and marshmallows constantly until the marshmallows are completely melted and the mixture is smooth. This step requires patience and attention to prevent the marshmallows from burning or sticking to the bottom of the pan. It will take approximately 3-5 minutes to fully melt.
5. Remove the saucepan from the heat. Immediately add 1/2 cup of peanut butter to the melted marshmallow mixture.
6. Stir until the peanut butter is fully incorporated and the mixture is smooth and creamy. This step should be done quickly to prevent the mixture from cooling down too much.
7. Pour the 8 cups of granola cereal into the saucepan with the peanut butter and marshmallow mixture.
8. Stir until the granola is evenly coated with the mixture. Ensure every piece of granola is coated for the best flavor and texture. This is where a large saucepan really shines.
9. Transfer the granola mixture to the prepared 9-inch square pan.
10. Using damp hands or a rubber spatula, press the mixture evenly into the pan. Damp hands prevent the mixture from sticking to your skin. Ensuring even distribution will make the bars look nice and neat.
11. Cool completely at room temperature before cutting into bars. This will take about 30 minutes to an hour. Cooling allows the bars to firm up, making them easier to cut and preventing them from crumbling.
12. Once cooled, cut into squares.
13. Store in an airtight container for up to 3 days.

Expert Tips & Tricks

• Butter matters: Using high-quality butter contributes significantly to the richness and flavor of the bars.
• Gentle melting: Keep the heat low and stir constantly to prevent the marshmallows from burning. Burnt marshmallows can impart a bitter taste to the bars.
• Don’t overmix: Be careful not to overmix the granola with the marshmallow mixture, as this can cause the granola to become crushed and lose its texture. Gently fold the granola into the mixture until just combined.
• Line the pan: For easier removal, line the pan with parchment paper, leaving an overhang on the sides. Once the bars are cooled, you can simply lift them out of the pan using the parchment paper.
• Uniform cutting: Use a sharp knife or pizza cutter to cut the bars into even squares. For cleaner cuts, run the knife under warm water before each cut.
• Add a salty finish: Sprinkle a pinch of flaky sea salt on top of the bars before they cool. The salt enhances the sweetness and adds a delightful contrast of flavors.

Serving & Storage Suggestions

These Peanut Butter Granola Bars are perfect as an on-the-go breakfast, an afternoon snack, or a satisfying dessert. They can be served at room temperature or slightly chilled. For a more elegant presentation, drizzle melted chocolate over the cooled bars before cutting them into squares.

To store, keep the bars in an airtight container at room temperature for up to 3 days. They can also be stored in the refrigerator for up to a week, but may become slightly harder. For longer storage, freeze the bars individually wrapped in plastic wrap for up to 2 months. Thaw at room temperature before serving.

FAQs (Frequently Asked Questions)

Q: Can I use regular-sized marshmallows instead of miniature marshmallows?
A: Yes, you can use regular-sized marshmallows. Just be sure to cut them into smaller pieces before melting to ensure they melt evenly.

Q: What if my granola bars are too sticky?
A: If your granola bars are too sticky, try adding a bit more granola to the mixture to help absorb some of the moisture. Also, make sure you’ve allowed the bars to cool completely before cutting them.

Q: Can I use a different kind of nut butter?
A: Absolutely! Almond butter, cashew butter, or even tahini can be used in place of peanut butter for a unique flavor profile.

Q: How do I prevent the granola from sticking to my hands when pressing it into the pan?
A: Dampening your hands with water or coating them lightly with cooking spray will prevent the granola from sticking.

Q: Can I add protein powder to these bars?
A: Yes, you can add about 1/4 cup of protein powder to the granola mixture. This will increase the protein content of the bars and make them a more filling snack. Just be mindful that some protein powders will make the recipe more dry and you may need to compensate with a bit more melted butter.
