01 - Combine cream cheese, cheddar cheese, crumbled bacon, diced jalapeños, garlic powder, onion powder, black pepper, and green onions in a medium bowl. Mix until thoroughly incorporated and creamy.
02 - Place an eggroll wrapper on a clean surface with one corner pointing toward you. Spoon 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 away from you and brush the final corner with beaten egg to seal securely.
04 - Repeat filling and rolling process with remaining wrappers and filling until all 12 eggrolls are assembled.
05 - Pour 2 inches of vegetable oil into a deep skillet or pot. Heat to 350°F, maintaining temperature throughout frying.
06 - Fry eggrolls in batches of 4-5, turning occasionally, until golden brown and crispy, approximately 3-4 minutes per batch. Avoid overcrowding the pot.
07 - Remove eggrolls with a slotted spoon and transfer to paper towels to drain excess oil. Let cool for 2-3 minutes before serving.
