Soak 14 skewers in water for at least 20 minutes before starting. Preheat the oven to 450 degrees F. Line a large rimmed baking sheet with foil. In a small bowl, mix 1/3 cup yogurt with garlic powder and salt. Then place the cheese crackers and pretzels in a large zip bag and crush with a rolling pin. Pour the crumbs onto a plate or shallow rimmed dish. (You can crush them separately and pour them onto separate plates if you like.)
Place the Half Stick of Land O Lakes® Unsalted Butter on the baking sheet and put it in the oven to melt the butter, 2-3 minutes. Once melted, tilt the baking sheet around until the melted butter has thoroughly coated the entire surface of the baking sheet.
Insert a skewer through the center of each chicken tender, leaving the longest portion of the skewer on one end for a handle. Use a basting brush to apply a thin coat of yogurt mixture over the entire surface of each chicken tender. Then hold the handle and dip each tender in the cracker and pretzel crumbs until thoroughly coated on all sides.
Press each chicken tender into the melted butter on the baking sheet, then flip and lay on the baking sheet so that both sides of the tender are well coated in butter, to form a crispy buttery crust. Arrange the chicken tenders on the baking sheet, alternating ends, so that all 14 are evenly spread out. Place on the bottom rack of the oven and bake for 15-17 minutes.
Meanwhile, whisk together the ingredients for the honey mustard sauce and set aside. Serve the baked chicken tenders warm with a side of honey mustard sauce.
