In a large mixing bowl, combine the corn kernels, gluten-free cornmeal, almond milk, melted coconut oil, maple syrup, baking powder, salt, and black pepper.
Mix until well combined.
Pour the mixture into a greased baking dish.
Bake for 30-35 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.
Let it cool for a few minutes before serving.
