In a large mixing bowl, combine the shredded cheddar cheese and softened cream cheese until well blended. Add in the diced jalapeños, garlic powder, onion powder, paprika, salt, and pepper. Mix thoroughly until all ingredients are fully incorporated and evenly distributed.

Scoop out small portions of the cheese mixture using your hands or a cookie scoop. Roll each portion into balls about 1 inch in diameter. Place the formed balls onto a baking sheet lined with parchment paper to prevent sticking.

Set up a breading station by placing flour in one bowl, beaten eggs in another bowl (if needed), and panko breadcrumbs in a third bowl. Dip each cheese ball first into the flour, then into the egg mixture (if using), and finally coat thoroughly with panko breadcrumbs.

In a deep skillet or frying pan, heat oil over medium-high heat until it reaches approximately 350°F (175°C). Ensure there's enough oil to submerge the bites halfway while frying to achieve an even golden brown color.

Carefully place several bites into the hot oil without overcrowding them. Fry each batch for about 3-5 minutes or until they turn golden brown and crispy on all sides. Use a slotted spoon to remove them from the oil and drain on paper towels.

Serve your Texas Roadhouse Rattlesnake Bites immediately while they're hot and crispy! Pair them with your favorite dipping sauce like ranch or spicy aioli for an extra kick that complements their cheesy goodness perfectly.
