Preheat oven to 350 degrees. Spray a 9 x 9 inch baking pan or similiar sized casserole dish with cooking spray and set aside.
In a large bowl, combine beans, cream cheese, Rotel, taco seasoning, and one cup of cheddar cheese. Mix to combine using a handheld mixer if necessary. Pour into baking dish and use a spatula to spread evenly. Sprinkle on remaining cheese.
Bake, uncovered, for 25 minutes until dip is warmed through and bubbly. Serve with chips.

Notes
Make the entire dish ahead of time and bake prior to serving. Works great as filling for a bean burrito as well.
