Preheat oven to package directions for baking chicken nuggets.1 Line two half-sheet pans with parchment paper. Set one aside, and place 20 chicken nuggets on the other pan. It's best to use nuggets that are more flat than round; they'll sit better in between the mini waffles. Bake the nuggets according to package directions, flipping them over halfway through cooking.2
To make the Maple Sriracha Glaze, place the unsalted butter in a large microwave proof bowl and heat in 30-second increments until the butter has melted, this should take about a minute. Then, add two tablespoons of maple syrup, two teaspoons of Sriracha hot sauce, and cayenne pepper. Whisk everything together until well combined, then set the bowl aside until ready to use.
To prepare the Maple Sriracha Sauce, place the mayonnaise, Dijon mustard, lemon juice, two tablespoons of maple syrup, two teaspoons of of Sriracha hot sauce, and garlic powder in a small bowl. Whisk everything together until well combined. Set the bowl aside until ready to use.
When you've got about five minutes left on the cooking time for the nuggets, go ahead and increase the oven temperature to 450°F. Then, use a bread knife to separate the mini waffles into individual pieces.3 Place the waffles on the other prepared sheet pan. After you have removed the pan with the nuggets and the oven reaches 450°F, bake the waffles for five minutes.
Once you've removed the nuggets from the oven, use a pair of silicone tongs to place them in the large bowl with the Maple Sriracha Glaze. Then, use the tongs to gently toss them in the glaze.
Remove the mini waffles from the oven and place half of them on a large serving platter. Then, use a small spoon to add a small amount, about half a teaspoon, of the Maple Sriracha Sauce to the bottom waffle. Use the tongs to place one glazed nugget on each prepared waffle. Top the nuggets with the remaining waffles. Serve immediately while still warm.
