Mix the jalapenos, cream cheese, plain greek yogurt, sharp cheddar cheese, ¾ cup parmesan cheese, onion powder and garlic powder in a bowl. Mix well manually or with an electric mixer until well combined.
Spread the mixture in a cast iron skillet or baking pan.
Mix the last ¼ cup of the parmesan and the panko together. If you don't have fresh parsley to top it with you can add some dried parsley to this mixture for color. Put mixture evenly on top of the cheese mixture.
Bake for 35-40 minutes until the cheese is bubbly and the top is brown. You can also pop it under a broiler for a minute to get the golden color on top.
Top with chopped parsley and serve immediately with chips or crackers.
