Step 1: Prepare Your Baking Dish. Start by greasing a 9x13 inch baking dish with a bit of butter or lining it with parchment paper for easy removal later.
Step 2: Combine the Base Ingredients. In a large mixing bowl, combine the Karo syrup (or brown rice syrup), creamy peanut butter, and 1/2 cup of sugar. Mix until smooth and well combined.
Step 3: Add the Crunchy Elements. Gently fold in the corn flakes, roasted salted cashews, and raw unsalted pecans into the peanut butter mixture.
Step 4: Incorporate the Chocolate Chips. Now, add the mini chocolate chips and the vanilla extract to the mixture. Stir until everything is combined.
Step 5: Press the Mixture into the Baking Dish. Transfer the mixture into your prepared baking dish. Press the mixture firmly into the bottom to create an even layer.
Step 6: Prepare the Topping. In a microwave-safe bowl, combine the 2 1/2 cups of dark or milk chocolate chips with the softened butter and the additional sugar.
Step 7: Chill and Set. Place the baking dish in the refrigerator for at least 1-2 hours, or until the chocolate topping is set.
Step 8: Slice and Serve. Once set, remove the bars from the refrigerator. Use a sharp knife to cut them into squares or rectangles.
