Creating this delightful cake is a straightforward process that can be accomplished in a few simple steps. Follow these instructions to bring a piece of Brazil into your kitchen:

1. Preheat the Oven:
   • Start by preheating your oven to 350°F (175°C). This ensures that your cake bakes evenly and achieves the perfect texture.
2. Prepare the Cake Batter:
   • In a large mixing bowl, combine the softened butter and granulated sugar. Use an electric mixer to cream them together until you achieve a light, fluffy consistency.
   • Add the eggs one at a time, beating well after each addition. This helps to incorporate air into the batter, making it lighter.
   • Blend in the sweet corn kernels, ensuring they are evenly distributed throughout the mixture.
3. Mix Dry Ingredients:
   • In a separate bowl, whisk together the cornmeal, baking powder, and salt. This step ensures that the leavening agent is evenly distributed, preventing any uneven rising.
4. Combine Wet and Dry Ingredients:
   • Gradually add the dry ingredients to the wet mixture, alternating with the milk. Begin and end with the dry ingredients, stirring gently after each addition.
   • Add the vanilla extract if using, and mix until just combined. Be careful not to overmix, as this can result in a dense cake.
5. Prepare the Baking Pan:
   • Grease a 9-inch round cake pan with butter or non-stick spray. You can also line it with parchment paper for easier removal of the cake.
6. Bake the Cake:
   • Pour the batter into the prepared cake pan, spreading it evenly with a spatula.
   • Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
7. Cool and Serve:
   • Allow the cake to cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
   • Once cooled, dust with powdered sugar if desired. Slice and serve to enjoy the sweet, corn-filled delight.
