Preheat your oven to 400°F. Grease a mini muffin tin or line it with mini muffin liners.
In a large bowl, whisk together the cornmeal, flour, baking powder, salt, and sugar until well combined.
In another bowl, mix the buttermilk, eggs, melted butter, and honey until smooth.
Pour the wet ingredients into the dry ingredients and stir until just combined. Gently fold in the corn kernels and cheddar cheese if using.
Spoon the batter into the prepared mini muffin tin, filling each cup about 2/3 full.
Bake for 12-15 minutes or until the tops are golden brown and a toothpick inserted into the center comes out clean.
While the cornbread poppers are baking, prepare the honey butter by mixing the softened butter, honey, and cinnamon in a small bowl until smooth and creamy.
Once the poppers are done, remove them from the oven and let them cool for a few minutes before transferring them to a wire rack. Serve warm with the honey butter.
