Combine the cornmeal, flour, baking powder and salt in a bowl. Lightly fold in teh eggs, honey and melted butter.
Fold in the blueberries.
Fill well-greased muffin tins about 2/3 full.
Mix sugar and cinnamon together. Sprinkle the sugar-cinnamon mixture on each of the muffins.
Bake for 20 to 25 minutes or until a toothpick inserted in the center of a muffin comes out clean.
Notes
These are moist and delicious as is, but just as good with 1 cup of grated unpeeled apple instead of the blueberries. (Think how attractive the tiny red flecks will look.)
