Place Ritz Bits sandwiches in a large ziploc bag or container with lid.

In a medium bowl, add the canola oil, ranch seasoning, red pepper flakes, and garlic powder. Pour over the Ritz Bits sandwiches in the ziploc bag.

Seal the bag or container and flip over a few times to ensure the crackers are evenly coated in the fire cracker mixture. Spread out over a baking sheet and allow to dry for 30 minutes.

Serve immediately or store in an airtight container for later.
