Adjust an oven rack to the middle position and heat the oven to 375°F. Grease a 10” cast iron skillet or a 9" square baking pan.
Whisk the flour, cornmeal, baking powder, baking soda, and salt together in a large bowl.
2 cups (10 oz) all-purpose flour, 1 cup (5 oz) yellow cornmeal, 1½ teaspoons baking powder, 1 teaspoon baking soda, 1 teaspoon salt
In a medium bowl, whisk the greek yogurt, sugar, milk, melted butter, and eggs together until smooth. Gently fold the Greek yogurt mixture into the flour mixture with a rubber spatula until just combined. Do not overmix. Fold in the corn kernels and blueberries.
¾ cup Greek yogurt, ½ cup white sugar, ½ cup whole milk, ½ cup unsalted butter, 2 large eggs, 1 can (11 oz) whole corn kernels, 1 cup blueberries
Pour the batter into the skillet and smooth the top. Bake until cornbread is golden yellow, about 17-20 minutes. Don’t over bake - you don’t want your cornbread to be dry! Remove from the oven and cool completely.
For the cinnamon honey butter, stir together all of the ingredients until fully combined. Serve with cornbread.
½ cup salted butter, 2 tablespoons honey, 1 teaspoon cinnamon
