Preheat oven to 400 degrees F. Coat a 24-cup mini muffin pan with baking spray or line with paper liners.
In a large bowl, combine cornmeal, flour, sugar, baking powder and salt. Add milk, oil and egg. Mix until just combined (some lumps are okay). Gently fold in blueberries.
Divide batter among greased cups, filling muffin cups 3/4 full. Bake until muffins are golden brown on top and a toothpick inserted into center comes out clean, 12 to 15 minutes. Cool slightly on a wire rack before removing from pan.
