"Fried" Chicken and Biscuits

"Fried" Chicken:
1/2 cup buttermilk
1 tablespoon Dijon mustard
2 cloves garlic, minced
1 teaspoon hot sauce
2 1/2-3 pounds chicken legs, skin removed, trimmed and cut into thighs and drumsticks
1/2 cup whole-wheat flour
2 tablespoons sesame seeds
1 1/2 teaspoons smoked paprika
1/4 teaspoon ancho chile powder
1/2 teaspoon onion powder
1/2 teaspoon cayenne pepper
1 tablespoon honey
1 teaspoon dried thyme leaves
1 teaspoon baking powder
1/8 teaspoon salt, or to taste
Freshly ground pepper to taste
Olive oil cooking spray
Directions
Whisk buttermilk, mustard, garlic, hot sauce and honey in a shallow glass dish until well blended. Add chicken and turn to coat. Cover and marinate in the refrigerator for at least 1/2 hour or for up to 8 hours.
Preheat oven to 425°F. Line a baking sheet with foil. Set a wire rack on the baking sheet and coat it with cooking spray.
Whisk flour, sesame seeds, spices, thyme, baking powder, salt and pepper in a small bowl. Place the flour mixture in a paper bag or large sealable plastic bag. Shaking off excess marinade, place one or two pieces of chicken at a time in the bag and shake to coat. Shake off excess flour and place chicken on the prepared rack. (Discard any leftover flour mixture and marinade.) Spray chicken pieces with cooking spray.
Bake the chicken until golden brown and no longer pink in the center, 40 to 50 minutes.

Biscuits:
3/4 cup buttermilk
1 tablespoon canola oil
1 cup whole-wheat pastry flour
1 cup all-purpose flour
1 tablespoon sugar
1 1/2 teaspoons baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
1 1/2 tablespoons cold butter, cut into small pieces
1 tablespoon milk for brushing
Directions
Preheat oven to 425 degrees F. Coat a baking sheet with cooking spray.
Combine buttermilk and oil. Whisk whole-wheat flour, all-purpose flour, sugar, baking powder, baking soda and salt in a large bowl. Using your fingertips or 2 knives, cut butter into the dry ingredients until crumbly. Make a well in the center and gradually pour in the buttermilk mixture, stirring with a fork until just combined.
Transfer the dough to a floured surface and sprinkle with a little flour. Lightly knead the dough 8 times, then pat or roll out to an even 3/4-inch thickness. Cut into 2-inch rounds and transfer to the prepared baking sheet. Gather any scraps of dough and cut more rounds. Brush the tops with milk.
Bake the biscuits for 12 to 16 minutes, or until golden brown. Transfer to a wire rack and let cool slightly before serving.
