Begin by lining an 8-inch square baking pan with wax or parchment paper, allowing some overhang for easy removal later.

In a microwave-safe bowl, warm your chosen nut butter for about 20-30 seconds until it becomes stirrable.

In a large mixing bowl, combine your cereal, melted nut butter, and liquid sweetener. Mix thoroughly until all components are evenly coated.

Carefully pour the cereal mixture into the prepared baking pan. Press down firmly to compact the mixture.

Place your pan in the refrigerator or freezer for at least 30 minutes to firm up.

Once set, remove the pan using the overhang and cut into evenly sized bars.

Store leftover cereal bars in an airtight container.
