Preheat your oven to 375°F (190°C). Prepare a baking sheet by lining it with parchment paper.
In a mixing bowl, combine the flour, garlic powder, paprika, salt, and pepper. In another bowl, whisk the eggs. Place the crushed pretzels in a third bowl.
Dip each chicken breast first in the flour mixture, then in the eggs, and finally coat with crushed pretzels. Place them on the prepared baking sheet.
Bake the chicken for 25 minutes or until fully cooked and golden brown.
While the chicken is baking, prepare the sauce by mixing together the cheddar cheese, Dijon mustard, sour cream, honey, and apple cider vinegar in a bowl.
Serve the baked chicken with the mustard-cheddar sauce on top.
