Preheat oven to 375 degrees F. Grease a 9-inch deep dish pie plate OR an 8x8 baking dish with non-stick spray.
Add cream cheese, garlic powder, onion powder and sour cream to a large bowl. Using an electric hand mixer, beat until combined and creamy.
Add drained jalapeños, cheddar cheese and 1/4 cup of the Parmesan cheese to mixture. Mix until combined. Spread mixture evenly into prepared pan.
Combine bread crumbs, remaining Parmesan cheese and olive oil to a medium bowl. Mix until combined then sprinkle evenly over the top of dip.
Bake 15-20 minutes, or until hot and breadcrumbs are golden brown. Remove from oven and garnish with chopped Parsley, if desired. Serve and enjoy!
