Start by draining your dill pickle chips and patting them dry with paper towels to prevent excess moisture and soggy coating.
Pour the buttermilk into a large bowl and set aside.
Place the pickle chips in the buttermilk, ensuring they are fully submerged. Let soak for 10 to 15 minutes to tenderize and help flour adhere.
In a separate bowl, whisk together whole-wheat flour, all-purpose flour, salt, paprika, and cayenne pepper to create the seasoned flour mixture.
Pour vegetable oil into a deep pot or fryer and heat to 350°F (175°C), using a thermometer to maintain temperature.
Remove pickles from buttermilk one by one, letting excess drip off, then dredge in the flour mixture. Press lightly and shake off excess flour.
Carefully lower a batch of coated pickles into the hot oil without overcrowding. Fry for 2 to 3 minutes until golden brown and crispy.
Use a slotted spoon to transfer fried pickles to a cooling rack over a baking sheet lined with paper towels to drain excess oil and keep crisp.
Serve immediately with your favorite dip such as ranch or spicy aioli for best flavor.
