Miss Judi's Spicy Crackers

I know this is a weird recipe but they are great. My 3 year old granddaughter can't stop eating them.
 


1 box of white crackers, 4 sleeves
1c cup canola oil
1-2 tablespoons red pepper flakes
1 packet dry ranch dressing mix
3 tablespoons grated Parmesan cheese
1 tablespoon Cayenne pepper, optional
1 large 2.5 gallon plastic bag

Put crackers in plastic bag and pour ingredients over the crackers. Mix by moving the bag around. Let the bag rest for a' couple of hours, turning the bag every 15 minutes.
