Cook 4 slices of bacon and let cool. Crumble.
Turn on Broiler to LOW
In a small bowl combine softened cream cheese, mayonnaise, and sour cream until smooth.
Add onion powder, garlic powder, black pepper, red pepper flakes, and bacon and stir.
Add all three shredded cheeses(reserve a little of the cheddar for the top) and stir.
Using a spatula, spread cheesy dip mixture into a prepared oven safe pan. If your pan isn't coated with enamel, you will probably want to grease it. Top mixture with reserved Cheddar cheese.
Broil on LOW for 7-9 minutes or until dip is heated through and the cheese on top is melted. NOTE: each oven broiler is different, please watch your dip carefully the first time and adjust as needed.
