In a large bowl, combine the flour, cornmeal, sugar, pudding mix, baking powder and salt.
Add the milk, oil, and eggs and mix until well combined.
Add the blueberries and cornstarch to a small bowl and toss to coat.
Add blueberries to the batter and lightly fold them in.
Grease an 8-count mini loaf pan (or muffin tin) and fill 3/4 full with batter.
Bake for 20-25 minutes, or until a toothpick comes out clean.
Notes
Loaf pan: I made this recipe in an 8-count mini loaf pan and it resulted in 8 perfect mini loaves. You can likely bake this recipe in a regular 9x5-inch loaf pan instead, but note that the bake time will be significantly increased.
