Cornbread is elevated to an entirely new level by adding frozen blueberries and lemon zest to the batter ! It's great for the kids' (or adults) lunch box for a morning snack/breakfast or dessert!
Toss blueberries with 1 tbsp of flour and set aside.
Combine flour, cornmeal, sugar, baking powder, and lemon zest in a large bowl. Stir with a whisk to evenly combine ingredients.
In a medium bowl, whisk egg, milk, vegetable oil, and vanilla extract.
Cool for at least 10 minutes before cutting. Serve warm or cold.
