Combine chicken, cream cheese, Treasure Cave Mild Crumbled Blue Cheese, cheddar cheese, green onions and ranch seasoning in a bowl.
Add Buffalo sauce and combine.
Lay out one egg roll wrapper on a cutting board with a point facing toward you so it looks like a diamond.

Fold over side corners toward the middle and then roll egg roll wrapper up toward top corner.
Repeat with remaining egg roll wrappers. Lay egg rolls on a baking sheet.
Heat oil in a large shallow pan on medium heat.
Working in batches, cook egg rolls on both sides until they are golden brown.
