Icebox Cookies ~Chocolate

These cookies have only 3/4 cup of flour in the dough which makes them rich and incredibly delicious. You can keep the dough in your freezer or refrigerator and bake them as needed for fresh gifts. Another gift idea – wrap some dough and baking instructions in a basket for your friends that like to bake.
1 1/4 pounds bittersweet chocolate, chopped
3/4 cup unsalted butter
1 1/3 cups sugar
4 large eggs
1 tablespoon vanilla extract
3/4 cup all-purpose flour
12-ounces semisweet chocolate chips
DIRECTIONS

Line a 8 x 8-inch pan with a double layer of plastic wrap. Melt chocolate and butter in heavy very large saucepan, stirring constantly over low heat until smooth. Remove from heat and cool slightly (you don’t want chips to melt when you add them.) Whisk in sugar, then eggs and vanilla. Stir in flour then chips. Pour dough into prepared pan, smoothing evenly.
Wrap in plastic and refrigerate overnight or up to 3 days. Using large sharp knife, cut dough into 3 even bars, about 2 1/2 x 8 inches each. (Can be made ahead. Wrap each bar in plastic and place in freezer bag and freeze up to 2 weeks. Thaw in refrigerator overnight before continuing.)
Preheat oven to 350 degrees F. Line heavy baking sheets with parchment or Exopat liners. Slice bars crosswise into 1/2 inch thick slices. Place on baking sheets, spacing about 2-inches apart. Bake until puffed in centered and wrinkled on top, about 15 minutes. Cool on pans. Store airtightly.
