Step-by-Step Instructions 5 (always use H2 and H3)

1. In a saucepan, combine peanut butter, honey (or corn syrup), and sugar. Heat over medium heat until melted and mixed well.

Heat gently, stirring often so the sugar dissolves and the peanut butter thins into a smooth sauce.

2. Remove from heat and stir in vanilla extract.

Take the pan off the burner and quickly mix in the vanilla for extra flavor.

3. Gently fold in cornflakes until evenly coated.

Add the cornflakes a little at a time and fold carefully to keep them from breaking up too much.

4. Drop spoonfuls of the mixture onto a waxed paper-lined tray.

Use a tablespoon or cookie scoop to portion even mounds spaced apart.

5. Allow to cool and set at room temperature. Enjoy your no-bake cookies!

Let cookies firm up for about 20–30 minutes before serving so they hold their shape.
