Combine flour, baking soda, baking powder, and salt in small bowl.
Alternate adding buttermilk and dry ingredients to creamed mixture until well incorporated.
Drop dough by teaspoon onto baking sheet about 2" apart. Bake for 15 minutes. Allow to cool before filling.
In a double broiler, heat flour, milk, and salt until it makes a paste.
Cream butter, sugar and vanilla together, then add the paste and beat until it is light and fluffy.
Spread filling between two cookies to make a sandwich. Enjoy!
Store any leftover chocolate whoopie pies in the refrigerator. You can either serve chilled or remove them from the fridge about 30 minutes before serving to allow them to come to room temperature. Cookies should be enjoyed within 5 days.Stir constantly to make sure that the mixture doesn’t burn as you are mixing to create the chocolate paste.Use a teaspoon measuring spoon to measure out the cookies to keep them about the same size.Buttermilk can be made by combining 1 cup milk with 1 TBS either white vinegar or lemon juice. Combine and let sit for 10 minutes before using in the recipe. Freeze whoopie pies after baked by wrapping them each individually in plastic wrap then putting into a plastic bag so you can thaw them individually as well. Thaw in the fridge overnight.
