Follow these step-by-step instructions carefully to ensure your Zucchini Cornbread Morning Bites turn out perfectly every time. The key is in the preparation of the zucchini and being careful not to overmix the batter.

1. Preheat and Prepare: Begin by preheating your oven to 400°F (200°C). Generously grease a 12-cup standard muffin tin with butter or non-stick cooking spray. Alternatively, you can use paper liners for easier cleanup.
2. Prepare the Zucchini: Wash and trim the ends of your zucchini. Using the large holes of a box grater, shred the zucchini. You should have about 1 ½ cups. Place the shredded zucchini in a clean kitchen towel or a few layers of paper towels. Wrap it up and squeeze firmly over the sink to remove as much excess moisture as possible. This is a critical step; removing the water prevents the bites from becoming soggy and ensures they bake properly. Set the squeezed zucchini aside.
3. Combine Dry Ingredients: In a large mixing bowl, whisk together the all-purpose flour, yellow cornmeal, granulated sugar, baking powder, baking soda, and salt. Whisking helps to evenly distribute the leavening agents, which ensures a consistent rise for all your bites.
4. Combine Wet Ingredients: In a separate medium-sized bowl, whisk the eggs until they are light and slightly frothy. Then, pour in the buttermilk and the melted butter, whisking until everything is well combined.
5. Mix the Batter: Pour the wet ingredient mixture into the large bowl with the dry ingredients. Using a spatula or a wooden spoon, mix until just combined. You should still see a few small streaks of flour. It is very important not to overmix the batter at this stage. Overmixing can develop the gluten in the flour, leading to tough, dense bites instead of light and tender ones.
6. Fold in the Add-ins: Gently fold the squeezed, shredded zucchini and the corn kernels (if using) into the batter. Mix only until they are evenly distributed throughout the batter. Again, be careful not to overmix.
7. Fill the Muffin Tin: Carefully divide the batter evenly among the 12 prepared muffin cups. An ice cream scoop works wonderfully for this, as it helps to create uniform portions. Each cup should be filled about two-thirds to three-quarters full.
8. Bake to Perfection: Place the muffin tin on the center rack of your preheated oven. Bake for 18-22 minutes, or until the tops are golden brown and a wooden toothpick inserted into the center of a bite comes out clean or with a few moist crumbs attached.
9. Cool Down: Once baked, remove the muffin tin from the oven and let the Zucchini Cornbread Morning Bites cool in the pan for about 5 minutes. This allows them to set up and makes them easier to remove. After 5 minutes, carefully transfer them to a wire rack to cool completely. This prevents the bottoms from becoming soggy as they cool.
