Prepare for baking: Preheat your oven to 450 F with rack in the middle
Make the honey butter: Combine the butter and honey in a small saucepan set over medium heat. Cook until butter is completely melted, stirring occasionally. Set aside and allow the mixture to cool.
Blend corn: Combine ⅓ cup of corn, sourdough discard and milk in a blender and puree.
Mix the wet ingredients: Whisk the corn mixture with the eggs and sugar until the sugar has completely dissolved.
Fold in the dry ingredients: Fold the cornmeal, salt, baking powder and baking soda into the wet ingredients. Add the all-purpose flour in three additions. Stir the remaining corn kernels in with the last addition of flour.
Drench batter in honey butter: Pour your batter into your 8-inch cake pan. Pour the melted honey butter over the batter.
Bake: Bake the cornbread for 30 to 35 minutes or until the tops are golden brown, the center no longer jiggles and a toothpick inserted into the center comes out clean.
Enjoy: Allow the cornbread to cool slightly before slicing. This cornbread is best enjoyed the day it's baked.
