Add the stick of butter to an 8x8" baking pan and put in the oven to melt the butter. Once the butter has melted remove from the oven and swish it around the baking pan to coat all the edges, etc.
8 Tablespoons Unsalted Butter
In a medium mixing bowl, add the other ingredients and pour in the melted butter, mix well with a whisk.
1 Cup Sour Cream, 2 Each Large Eggs, 1 Cup Cream Style Corn, 1 Cup Self-Rising Cornmeal, ½ Each Yellow Onions
Pour batter into the baking pan and straight into the oven.
Bake in the oven for 35-40 minutes. Remove and allow to cool slightly before cutting into it.
Notes
Don't add hot butter to the mixture with the eggs or you'll cook the egg. Allow the butter to cool a little first.
