In a small saucepan, melt butter and brown sugar together.
Stir continuously and bring to a boil. Boil for 1 minute and remove from heat.
Stir in cinnamon and vanilla.
Immediately add a handful of Ritz Bits to the saucepan and cover them individually in the sugar coating. Pick them up with a fork, allowing the excess coating to drain off and place them in the air fryer basket. They shouldn’t be overlapping but they can be touching slightly.
Cook for 7 minutes or until bubbly.
In a gallon size bag, shake together the sugar, cinnamon, and salt.
Toss the candied Ritz Bits into the bag in batches and shake to coat.
Serve warm or at room temperature.
