Recipe: Fudge Filled Chocolate Chip and Mounds Cookies

After many hours of searching the net, this is pretty darn close to what I was looking for:

Fudge Filled Chocolate Chip and Mounds Cookies
Makes about 36

1/2 cup flaked coconut
1 cup milk
1/2 cup white sugar
1 1/2 tablespoons cornstarch

3 cups all-purpose flour
2 tablespoons unsweetened cocoa powder
1 teaspoon baking soda
2 teaspoons cream of tartar
1/2 teaspoon salt
1/2 cup butter, softened
1 cup white sugar
1 teaspoon vanilla extract
1 egg, beaten
1 cup milk

Preheat the oven to 375 degrees F (190 degrees C). Grease cookie sheets. Prepare the filling first. In a 2 quart saucepan, over medium heat, stir together the milk and coconut. Combine the cornstarch and 1/2 cup of sugar; stir into the saucepan. Bring to a simmer and cook, stirring constantly until thickened. Remove from heat and set aside to cool.

Sift together the flour, cocoa, baking soda, cream of tartar and salt; set aside. In a medium bowl, cream together the butter, 1 cup sugar and vanilla until smooth. Stir in the egg and milk. Gradually mix in the sifted ingredients to form a dough. On a lightly floured surface, roll the dough out to 1/4 inch in thickness. Cut into 2 1/2 inch circles with a cookie cutter. Place half of the circles 1 1/2 inches apart onto the prepared cookie sheets. Spoon about 1 teaspoon of the filling onto the center of each cookie on the pan. Top with another circle and seal the edges by pinching.

Bake for 8 to 10 minutes in the preheated oven. Allow cookies to cool on baking sheet for 5 minutes before removing to a wire rack to cool completely.
