First, preheat your oven to 375°F (190°C). This ensures the poppers start cooking immediately and rise properly. Generously grease a 24-cup mini muffin tin with butter or non-stick spray to prevent the poppers from sticking and ensure they come out easily.
In a medium-sized mixing bowl, combine the yellow cornmeal, all-purpose flour, granulated sugar, baking powder, and salt. Use a whisk to mix them together thoroughly. This step ensures that the leavening agent and salt are evenly distributed throughout the batter.
In a separate, larger bowl, whisk together the milk, ¼ cup of melted butter, 2 tablespoons of honey, and the large egg. Continue whisking until the mixture is smooth and well combined. This creates the rich, liquid base for your cornbread batter.
Pour the wet ingredients into the bowl with the dry ingredients. Gently fold them together with a spatula just until the flour streaks disappear. Be careful not to overmix. A few lumps are perfectly fine. Finally, gently fold in the corn kernels.
Spoon the batter evenly into the prepared mini muffin tin cups. Fill each cup about three-quarters of the way full. This will give the poppers enough room to rise and form their classic domed tops without overflowing during the baking process.
Place the muffin tin in the preheated oven and bake for 12 to 15 minutes. The poppers are done when they are golden brown and a toothpick inserted into the center of one comes out clean. Keep a close eye on them during the final minutes to prevent overbaking.
While the poppers are baking, prepare the glaze. In a small bowl, whisk together the remaining ¼ cup of melted butter and 2 tablespoons of honey until smooth. As soon as the poppers come out of the oven, brush this warm glaze generously over the tops of each one.
