01 - Combine cream cheese, cheddar cheese, crumbled bacon, diced jalapeños, garlic powder, onion powder, black pepper, and sliced green onions in a medium bowl. Mix thoroughly until all ingredients are evenly distributed.
02 - Place an eggroll wrapper on a clean surface with one corner pointing toward you. Spoon approximately 2 tablespoons of filling into the center of the wrapper.
03 - Fold the bottom corner over the filling, then fold in both side corners. Roll tightly upward and brush the final corner with beaten egg to seal securely. Repeat with remaining wrappers and filling.
04 - Pour vegetable oil to a depth of 2 inches in a deep skillet or pot. Heat to 350°F, maintaining temperature throughout frying.
05 - Fry eggrolls in batches of 4-5 to avoid overcrowding. Turn occasionally for even cooking and fry until golden brown and crispy, approximately 3-4 minutes per batch.
06 - Remove eggrolls with a slotted spoon and transfer to paper towels to drain excess oil. Let cool for 2-3 minutes before serving.
