Well...this certainly isn't something you see everyday.
I'm on a blackberry kick. My bird Murphy also likes blackberries. Murphy has a bit of a plucking issue, but that doesn't stop him from being adorable. He also looks a bit like a blackberry (fruit not outdated smartphone).
1 cup yellow cornmeal
1 cup flour
1/3 cup sugar, plus more for sprinkling
2 teaspoons baking powder
1 teaspoon kosher salt
3/4 cup buttermilk
7 tablespoons unsalted butter, melted
1 1/2 cups blackberries
Preheat oven to 375 degrees. Grease an 8-inch square glass baking dish, and set aside.
In a large bowl, whisk together cornmeal, flour, sugar, baking powder, and salt.
In a medium bowl, whisk together buttermilk, eggs, and butter.
Pour liquid mixture into the dry mixture, and stir until thoroughly combined. Evenly spread batter into the prepared pan.
Scatter 1 cup of the blackberries over the top of the batter, and press gently until mostly submerged. Scatter the remaining berries on top, and lightly sprinkle with sugar.
Bake for 25-30 minutes, until golden brown around edges and springy to the touch. Cool for 10 minutes before cutting.
