In a bowl whisk together flour, cornmeal, baking powder, and salt. In a separate bowl whisk together the cooled melted butter, egg, honey, sugar, and milk.
Stir the butter mixture into the flour mixture, incorporating until the batter is just combined. Fold in the blueberries. Don’t overmix!
Divide the batter among 12 1/2-cup muffin tins (use cupcake liners or grease tins with butter). Bake on the center rack for 15 to 20 minutes, or until muffins are golden brown and a toothpick comes out clean. Let them cool on a wire rack. Enjoy!
