01 - Preheat vegetable oil in a deep fryer or a large, heavy-bottomed pot to 350°F (175°C).
02 - Slice each jalapeño pepper lengthwise. Carefully remove the seeds and membranes using a small spoon. It is recommended to wear gloves during this step to avoid skin irritation.
03 - In a mixing bowl, combine the softened cream cheese, shredded cheddar cheese, minced garlic, onion powder, smoked paprika, salt, and black pepper. Stir until the mixture is smooth and well incorporated.
04 - Generously fill each jalapeño half with the prepared cheese mixture, smoothing the top surface to create an even layer.
05 - Arrange three shallow bowls. Place the all-purpose flour in the first bowl, whisk the eggs with milk in the second bowl, and place the plain breadcrumbs in the third bowl.
06 - Dredge each stuffed jalapeño half first in the flour, ensuring an even coating. Next, dip it into the egg and milk mixture, allowing any excess to drip off. Finally, coat thoroughly with the breadcrumbs, pressing gently to adhere.
07 - Fry the breaded jalapeño poppers in batches in the hot oil for 2-3 minutes, or until they achieve a golden brown and crispy exterior. Remove from the oil using a slotted spoon or tongs and drain on paper towels.
08 - Allow the fried poppers to cool slightly before serving.
