Preheat your oven to 375°F (190°C). Line a 9×9-inch baking pan with parchment paper and coat lightly with melted butter or cooking spray.
This is an easy one bowl recipe, which I love. Start by adding your butter to a mixing bowl, and melt in the microwave.
⅓ (75g) cup unsalted butter
Add the oil, honey, eggs, egg yolk, sourdough discard, buttermilk, and vanilla to the melted butter and whisk until smooth.
⅓ (80g) cup avocado oil, 2 (42g) tablespoons honey, 2 eggs, 1 egg yolk, ½ (120g) cup sourdough discard , 1 (240g) cup buttermilk, 1 teaspoon vanilla extract
Next add the flour, cornmeal, sugar, baking powder, baking soda, and salt to the wet ingredients. Whisk gently until the batter is just combined and no streaks of flour remain. Don't overmix at this stage!
1¼ (155g) cups all-purpose flour, 1 (160g) cup fine yellow cornmeal, ¾ (150g) cup granulated white sugar, 1½ teaspoons baking powder, ¼ teaspoon baking soda, 1 teaspoon fine sea salt
Allow the batter to rest for ten minutes to allow the cornmeal to hydrate (this is important don't skip this step).
Overnight Fermentation Option: At this point you have the choice to ferment the batter overnight. If you choose to ferment, cover the bowl with plastic and transfer to the refrigerator overnight.
