1Preheat your oven to 350°F (175°C) and lightly grease a baking dish.
In a large mixing bowl, combine the masa harina, all-purpose flour, sugar, baking powder, and salt.
In another bowl, whisk together the melted butter, milk, and eggs until well combined.
Gradually add the wet ingredients to the dry ingredients, stirring until just combined.
Fold in the corn kernels and diced jalapeños.
Pour the batter into the prepared baking dish, spreading it evenly.
Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
Allow the tamale cake to cool slightly before serving. Enjoy your Mexican Corn Tamale Cake!
