In a mixing bowl, combine the diced jalapeños, shredded cheddar cheese, and softened cream cheese. Mix well until all the ingredients are thoroughly combined.
In a separate bowl, whisk together the flour, baking powder, garlic powder, salt, and black pepper.
In another bowl, beat the eggs and add the milk, mixing until well combined.
Gradually add the wet mixture to the dry ingredients, stirring until a thick batter forms.
Gently fold the cheesy jalapeño mixture into the batter until evenly distributed.
Using your hands, scoop out portions of the mixture and roll them into balls about 1 inch in diameter.
In a shallow dish, place the breadcrumbs. Roll each ball in the breadcrumbs until fully coated.
Heat oil in a deep fryer or large pot to 350°F (175°C).
Carefully drop the battered balls into the hot oil, frying in batches to avoid overcrowding. Fry for about 3-4 minutes or until golden brown.
Remove the Rattlesnake Bites using a slotted spoon and place them on a paper towel-lined baking sheet to drain excess oil.
Serve hot with ranch or your favorite dipping sauce.
