Ingredients
- 1 cup creamy peanut butter
- 1 cup light corn syrup
- 1 cup granulated sugar
- 4 cups crispy rice cereal
Instructions
Step 1: Prepare the Pan
Lightly grease a 9-by-13-inch baking pan or line it with parchment paper, leaving a little overhang on the sides. Set aside.
Step 2: Heat the Syrup Mixture
Combine the corn syrup and granulated sugar in a large saucepan. Heat over medium-low heat, stirring constantly, until the sugar dissolves and the mixture just begins to bubble around the edges.
Do not let it boil vigorously, as overheating can make the finished bars too hard.
Step 3: Add the Peanut Butter
Remove the saucepan from the heat. Stir in the peanut butter until the mixture is completely smooth and creamy.
Step 4: Fold in the Cereal
Add the crispy rice cereal to the saucepan. Gently fold until every piece is evenly coated with the peanut butter syrup mixture.
Step 5: Press into the Pan
Transfer the mixture to the prepared baking pan. Use a lightly greased spatula to spread it evenly. Press gently so the bars hold together without crushing the cereal.
Step 6: Cool and Slice
Allow the slab to cool at room temperature for about 1 to 2 hours, or until firm. Lift it from the pan and cut into squares or rectangular bars.
Helpful Tips
- Use creamy peanut butter for the smoothest texture.
- Measure the cereal accurately so the bars remain chewy and hold together.
- Avoid cooking the syrup mixture for too long.
- Lightly grease your spatula to make pressing easier.
- Let the slab cool completely before slicing for cleaner edges.
- For thicker bars, use a smaller square baking pan and allow extra setting time.
Optional Variations
- Chocolate topping: Melt chocolate chips and spread a thin layer over the cooled slab.
- Crunchy peanut butter: Replace creamy peanut butter with crunchy peanut butter for extra texture.
- Vanilla flavor: Stir in 1 teaspoon of vanilla extract after removing the syrup mixture from the heat.
- Salted finish: Sprinkle a little flaky salt over the top before the mixture sets.
These additions are optional and are not included in the four core ingredients.
Serving Suggestions
Serve these peanut butter syrup slabs with a glass of cold milk, a cup of coffee, or hot chocolate. They also make a delicious addition to dessert platters, bake sales, and family gatherings.
For smaller portions, cut the slab into bite-sized squares. For a more substantial treat, slice it into larger bars.
Storage Instructions
- Room temperature: Store in an airtight container for up to 5 days.
- Refrigerator: Keep refrigerated for up to 1 week if your kitchen is warm.
- Freezer: Wrap individual bars and freeze for up to 2 months. Thaw at room temperature before serving.
Place parchment paper between layers to prevent the bars from sticking together.
Frequently Asked Questions
Can I use natural peanut butter?
Conventional creamy peanut butter works best because it has a more consistent texture. Natural peanut butter may separate and can make the bars less predictable.
Why are my bars too hard?
The syrup mixture may have been heated too long or boiled too vigorously. Heat only until the sugar dissolves and the mixture begins bubbling gently.
Can I make these without baking?
Yes. These are no-bake bars. The stovetop is used only to prepare the peanut butter syrup mixture.
How do I keep the bars from sticking to the knife?
Allow them to cool completely and lightly grease the knife before slicing.
Can I make them ahead?
Absolutely. Prepare them a day ahead, let them set completely, and store them in an airtight container until serving.
