Ingredients
1 16 1/2 ounce package refrigerated peanut butter cookie dough
3/4 cup butter
3 ounces unsweetened chocolate, coarsely chopped
1 1/3 cups sugar
2 teaspoons vanilla
3 eggs
1 cup all-purpose flour
2 tablespoons unsweetened cocoa powder
1/3 cup cherry or strawberry jam, jelly, or preserves
Preparation
Preheat oven according to cookie package directions. On a lightly floured surface, use hands to slightly flatten cookie dough to an 8x2-1/2-inch log. Place on baking sheet, then freeze for 30 minutes. Slice dough in half lengthwise, then slice each half in 16 slices. Place slices on cookie sheets. Using a fork dipped in granulated sugar, make a crisscross pattern on each cookie. Bake cookies according to package directions or until golden brown. Cool on wire racks.
Meanwhile, in a medium saucepan stir butter and chocolate over low heat just until melted. Remove from heat. Using a wooden spoon, stir in sugar and vanilla. Cool 5 minutes.
Set oven to 350 degrees F. Line the bottom and sides of an 8x8x2-inch baking pan with heavy foil, extending foil over pan edges. Grease foil; set pan aside.
Add eggs, one at a time, to butter-chocolate mixture, beating after each just until combined. Stir in flour and cocoa powder. Evenly spread batter in prepared pan.
Bake for 30 to 35 minutes, just until a wooden toothpick inserted near center comes out clean. Transfer to wire rack. Leave oven set to 350 degrees F to warm sandwich cookies.
For sandwich cookies, scoop and mash warm brownie onto the flat side of a cookie. Top with 1 tsp. jam and a second cookie. Place sandwich cookies that will be served immediately on a cookie sheet and warm in oven about 4 minutes.
TIP Store leftover brownies in a covered container up to 3 days.
