Melt 1/2 cup (1 stick) of butter in a sauce pan on medium heat.
Dice up the onions and celery and add to melted butter.
Saute the onion and celery until the onions become translucent. Careful not to burn them.
While the onions and celery are cooking, crumble the cornbread into a 9x13 glass dish.
Take 2 cups of your homemade stuffing mix and spread evenly over the cornbread.
Once the onions and celery have cooked down, pour them and the melted butter over the crumbled cornbread.
Place the other 1/2 cup of butter into the saucepan and allow it to melt.
In a large bowl combine the chicken stock and eggs and mix until well incorporated.
Pour the rest of the melted butter into the bowl with chicken stock and eggs.
Whisk in the dry ingredients.
Pour this mixture evenly over the cornbread and stuffing mix in your 9x13 baking dish.
Take a spoon and mix it well making sure all of the dry ingredients are coated with the broth mix.
Bake at 350 for approximately 45 minutes or until golden brown.
