1/2 cup Unsalted Butter softened
3/4 cup Granulated Sugar
2 large Eggs
1 Egg Yolk
1 3/4 cups All-Purpose Flour
1 teaspoon Baking Powder
1/4 teaspoon Kosher Salt
1/2 cup Cocoa Powder
1/2 cup Semi-Sweet Chocolate Chips
Preheat oven to 350ºF.
Line a baking sheet with parchment paper. Set aside.
In the bowl of your electric mixer, using the paddle attachment, cream the butter and sugar. When creamed, it should be very light colored, like off-white. Add the eggs and egg yolk, one at a time, mixing well after each addition.
In a separate bowl, whisk together the flour, baking powder, salt, and cocoa powder. Add to the butter mixture and beat to combine.
Stir in the dried cranberries and chocolate chips.
Transfer the dough to a floured surface and divide it in half. Form each half into a log about 12 inches long.
Transfer the logs to the baking sheet, spacing them well apart, and pat to even the shapes.
Bake until firm to the touch, about 35 minutes (logs will spread during baking).
Remove from the oven, place on a wire rack, and let cool for about 10 minutes.
Transfer the logs to a cutting board. Using a serrated knife carefully cut the logs into slices about 1 inch thick on the diagonal.
Arrange the slices on the baking sheet in a single layer and bake for about 10 minutes. Turn the slices over and bake until crisp and dry, about 10 minutes longer. Remove from oven and let cool on wire rack.
Once cooled, I like to dip half of the cookie in melted white chocolate, place it on a cookie sheet and let it dry to form a shell.
