Since I can’t go to Mueller’s Bakery in Bay Head, NJ, these will have to do. And they do just fine.
2 ½ cups flour
1 teaspoon baking soda
1 teaspoon baking powder
¼ teaspoon salt
1 ½ sticks butter, softened
1/1/2 cups sugar
2 large eggs
1 ¼ cups buttermilk

1 teaspoon salt
2 ½ sticks butter, melted
3 cups flour
½ cup powdered sugar for dusting
Mix both sugars, cinnamon, and salt in medium mixing bowl. Add the warm melted butter and stir to blend.
