Preheat oven to 375 degrees F. Grease a mini muffin pan with non-stick spray and set aside.: The oven heat warms the air so when you slide the tray in, the batter begins to rise right away, producing a light, tender crumb with slightly crisp edges. You should smell a faint warm, toasty scent as the oven comes to temperature, and the pan should feel evenly warm to the touch when you place your hand above it from a safe distance. Greasing the mini muffin pan ensures the nuggets release cleanly, preserving their cute shape. A common mistake is under greasing which can make the bites stick and tear when removed, so make sure you coat every well evenly with non stick spray or a light swipe of oil.
Prepare the Corn Muffin Mix by whisking together the dry mix with the creamed corn, egg and milk. Spoon the mixture in by the teaspoon full.: As you whisk, notice the batter transform from dry crumbs into a glossy, slightly lumpy mixture. The batter should be thick but pourable, with little flecks of corn visible from the creamed corn . The sound is a subtle scrape of the whisk against the bowl, and the aroma becomes mildly sweet and eggy. This mixing step hydrates the dry mix and activates the leavening agents so the nuggets can puff. Avoid overmixing, which can develop gluten and make the texture chewy rather than tender, especially since the batter contains a corn component. If the batter looks too stiff, add a teaspoon of milk at a time to loosen it slightly.
Cut your hot dogs into bite-sized pieces and place on top of the muffin mix.: Spoon small, measured amounts of batter into each greased mini muffin well so they cook evenly and the final texture is uniform. The batter should sit about halfway up each well, creating room for the hot dogs and a little rise. You'll notice the batter is slightly grainy from the corn mix, and it spreads slowly once in the warm pan. A common oversight is overfilling, which can cause spillover and uneven baking, so keep portions consistent using a teaspoon measure or small cookie scoop.
Spoon about one and a half teaspoons of the mix over each hot dog. {I did half regular and half with cheese added.}: Cutting the hot dogs into even pieces ensures uniform cooking and perfect proportion in each bite. Place each piece gently into the center of the batter mound so the batter will rise around it. You should feel the solidity of the meat against the soft batter, and visually the contrast is clear, a pink center nestled in yellow batter. Avoid pushing the piece down too far, which can sink it completely and lead to dry edges around the top. Aim for the top third of the piece to remain exposed so it crisps nicely.
Bake at 15 to 20 min. or until golden brown on top.: Adding a small additional dollop seals the hot dogs in and creates a finished dome that browns evenly. The extra batter cushions the meat, producing a delicate crown that will show golden hues as it bakes. You may see a little batter settle and spread toward the edges, and the scent will shift to a more pronounced baked corn aroma. One mistake is adding too much batter, which buries the hot dog completely and diminishes the contrast in textures, so keep it to roughly one and a half teaspoons for each nugget.
Bake at 15 to 20 min or until golden brown on top: During baking you will hear the oven hum and the faint pop of hot air as moisture escapes, while the tops take on a warm, golden brown color. The texture transitions from wet batter to a set, tender crumb with crisped edges. You can test doneness by gently pressing the top to ensure it springs back slightly, and visually the edges will be a little darker than the center. If you pull them too early, the centers may be underdone and collapse; if you leave them too long they will dry out. Aim for that sweet spot when the tops are golden and a toothpick inserted in the edge comes out mostly clean.
