Heavenly Devil Dogs: Irresistible American Recipe

1. Make the cake batter: Beat sugar and butter in a mixing bowl with an electric mixer until creamy. Mix in egg.

2. Sift flour, cocoa powder, baking soda, baking powder, and salt together into a bowl. Gradually mix dry ingredients into wet ingredients. Mix in milk and vanilla.

3. Drop heaping tablespoons of batter onto ungreased cookie sheets to make an even number of cookies; there should be about 24.

4. Bake in the preheated oven until cookies spring back when touched or a toothpick inserted into the center comes out clean, 7 to 8 minutes. Remove from the oven and let cool completely.

5. While the cookies are cooling, make the filling: Whisk milk and flour together in a saucepan over low heat until a thick paste forms. Remove from the heat and cool completely.

6. Beat sugar, shortening, vanilla, and salt in a bowl until creamy. Add cooled paste mixture and beat until fluffy; this could take some time and if paste is not completely cooled, it will look curdled.

7. Spread filling onto half of the cooled cookies; sandwich with remaining cookies.

Tips

I usually double the filling ingredients when I make this recipe.
