Peanut Butter Cornflake Bars — Do This Next

Step 1: Prepare Your Baking Pan
Start by lining your 9×13-inch baking pan with parchment paper, allowing some excess to hang over the sides. This will help you lift the bars out easily once they are set.
Step 2: Mix the Ingredients
In a large mixing bowl, combine the peanut butter and maple syrup. You can microwave the peanut butter for about 15-20 seconds if it’s too thick, making it easier to mix. Stir until the mixture is smooth and well combined.
Step 3: Add the Corn Flakes
Gently fold the cornflakes into the peanut butter and maple syrup mixture. Be careful not to crush the cornflakes too much; you want to maintain that delightful crunch.
Step 4: Transfer to the Pan
Pour the mixture into your prepared baking pan, spreading it evenly with a spatula. Press down firmly to ensure the bars hold their shape once set.
Step 5: Chill and Set
Refrigerate the bars for at least 1 hour, or until they are firm enough to cut. If you’re in a hurry, you can place them in the freezer for about 30 minutes.
Step 6: Cut and Serve
Once set, use the edges of the parchment paper to lift the bars out of the pan. Cut them into squares or rectangles, and enjoy your homemade Peanut Butter Cornflake Bars!
Seasonal Serving Ideas

- Top with sliced bananas or berries for a fresh touch during summer.
- Drizzle with melted dark chocolate for a festive treat during the holidays.

Common Errors (and Fixes)
- Bars are Crumbly: If your bars fall apart, try pressing them down more firmly before refrigerating. Ensure your peanut butter is well mixed with the syrup.
- Too Sweet: Reduce the amount of maple syrup in your next batch if you find them overly sweet. You can also mix in unsweetened cocoa powder for a balance.
- Cornflakes are Soggy: Ensure you’re using fresh cornflakes. Stale flakes can absorb moisture and lose their crunch.
