Ingredients You’ll Need
These ingredients are delightfully straightforward yet essential for the ultimate texture and flavor harmony in your bars. Each element plays its role: the peanut butter brings that creamy richness, corn syrup ensures everything sticks together without crystallizing, sugar contributes the perfect sweet balance, and cornflakes provide satisfying crunch and lightness.
- 1 cup creamy peanut butter: Using smooth peanut butter ensures an even, luscious texture that blends gorgeously with the other ingredients.
- 1/2 cup light corn syrup: This helps bind the mixture perfectly without making the bars too hard once set.
- 1/2 cup sugar: Granulated sugar sweetens without overpowering and aids in achieving the ideal chewiness.
- 6 cups cornflakes: The star crunch component that gives these bars their delightful texture and classic flaky appeal.
How to Make Sweet Peanut Butter Cornflake Bars Recipe
Step 1: Prepare the Binding Mixture
Start by gently heating the peanut butter, light corn syrup, and sugar together in a medium saucepan over low heat. Stir continuously until the sugar dissolves completely and the mixture is smooth and glossy. This warming process creates a sticky base that holds all your cornflakes together perfectly, delivering that irresistible chew without any graininess.
Step 2: Combine with Cornflakes
Once your peanut butter mixture is velvety and combined, remove it from heat and immediately pour over the cornflakes in a large bowl. Using a spatula or wooden spoon, fold the mixture gently but thoroughly into the cornflakes to coat every flake evenly. This step ensures that each bar will have a perfect balance of crunch and creamy pockets of peanut butter flavor.
Step 3: Press the Mixture Into a Pan
Line a square baking pan with parchment paper or lightly grease it, then transfer your coated cornflake mixture into the pan. Use the back of a spatula or your hands (lightly greased to avoid sticking) to press the mixture firmly and evenly. Firm pressing helps the bars set compactly, making them easier to cut and handle once chilled.
Step 4: Chill and Slice
Place the pan in the refrigerator for at least an hour to let the bars firm up completely. When ready, lift them out using the parchment paper and cut into 12 equal-sized bars. The chilling time is key for giving these bars their signature chew and to prevent crumbling as you serve.
How to Serve Sweet Peanut Butter Cornflake Bars Recipe

Garnishes
For an extra-special presentation, drizzle your bars with melted chocolate or a sprinkle of toasted chopped peanuts. These little touches add contrast in flavor and an elevated look, perfect for sharing at gatherings or gifting to friends.
Side Dishes
These bars pair wonderfully with a glass of cold milk, a cup of rich coffee, or even a fruity smoothie. Their sweet and crunchy nature makes them versatile, so feel free to complement the flavors with your favorite beverage or fresh fruit for a balanced snack experience.
Creative Ways to Present
Try stacking your Sweet Peanut Butter Cornflake Bars Recipe pieces on a decorative platter layered with wax paper or tying stacks with colorful ribbon for cute, grab-and-go treats. You can also serve smaller bite-sized squares on skewers for an easy party snack that’s fun and accessible for everyone.
Make Ahead and Storage
Storing Leftovers
Keep your bars fresh by storing them in an airtight container at room temperature for up to 3 days. If your kitchen tends to get warm, it’s better to refrigerate to maintain their firmness without losing that wonderful chewy texture.
Freezing
You can freeze these bars for longer storage by wrapping them individually in plastic wrap and placing them in a freezer-safe bag. They’ll keep nicely for up to 2 months. When you want a treat, simply thaw at room temperature for 10-15 minutes before enjoying.
Reheating
Usually, these bars are best served chilled or at room temperature. However, if you prefer a softer texture, gently warm them in the microwave for 10-15 seconds. Just be careful not to overheat as the peanut butter can get oily and hot quickly.
FAQs
Can I use crunchy peanut butter instead of creamy?
Absolutely! Crunchy peanut butter will add extra texture to your bars, making them even more interesting. Just keep in mind the overall consistency might be a bit chunkier.
Is there a substitute for light corn syrup?
If you don’t have light corn syrup, you can substitute with honey or golden syrup, but the texture might be slightly different since corn syrup controls crystallization and chewiness uniquely.
Can I add chocolate chips or other mix-ins?
Yes! Feel free to stir in chocolate chips, dried fruit, or even mini marshmallows for a fun twist. Add these after mixing the peanut butter blend with cornflakes for best distribution.
What’s the best way to cut the bars without crumbling?
Use a sharp knife and, for cleaner cuts, warm the blade slightly under hot water and dry it before slicing. This helps cut through the bars smoothly without breaking them apart.
Are these bars gluten-free?
They can be if you use gluten-free cornflakes, as some brands contain barley malt. Always double-check the cornflakes packaging if gluten is a concern.
