Bacon Cookies

Step 1
Fry bacon pieces in a large skillet over medium heat until crispy. Remove with a slotted spoon to paper towels, and cool completely.

Step 2
Into a large mixing bowl, place the flour, butter or margarine, egg, salt, and heavy cream. Using the mixer's hook attachment, mix the contents of the bowl together until combined; then transfer the dough to the counter, and quickly mix with your hands. Knead in cooled bacon pieces and pepper.

Step 3
Roll up the dough into a log, to a diameter of about 1 1/2 inches. Wrap in aluminum foil, and refrigerate for 2 hours, until firm.

Step 4
Preheat oven to 350 degrees F (175 degrees C). Remove foil, cut dough roll into slices, and place slices on greased baking sheet. Brush each slice with beaten egg yolk.

Step 5
Bake in a preheated oven for 12 to 15 minutes, until brown. Remove to a wire rack until cooled completely.
