With a cheese grater, grate the 4 oz of cheddar cheese and jalapeno pepper cheese. You want them in block form not pre shredded. Pre shredded won’t melt as well. Then set aside.
In crock pot add in cream cheese, frozen corn, jalapeno de seeded & diced, sour cream, mayonnaise, finely diced red onion, garlic cloves minced, shredded cheese, juice of 1 lime, salt, chili powder & cayenne pepper.
Place on low for 2 hours. Stirring once after 30 minutes and then another time 30 minutes later
Once the dip is done, stir in cilantro, add to a serving bowl and top with cotija cheese and enjoy!! ( I personally like to add to a bowl instead of eating out of the Crock Pot because I like when the dip cools slightly and becomes thicker! Personal preference)
