Homemade Oreos

From This Week for Dinner

Makes 25 to 30 sandwich cookies

Chocolate Wafers:
- 1 1/4 cups all-purpose flour
- 1/2 cup unsweetened Dutch process cocoa
- 1 teaspoon baking soda
- 1/4 teaspoon baking powder
- 1/4 teaspoon salt
- 1 1/2 cups sugar
- 1/2 cup plus 2 tablespoons (1 1/4 sticks) room-temperature, unsalted butter
- 1 large egg

Filling:
- 1/4 cup (1/2 stick) room-temperature, unsalted butter
- 1/4 cup vegetable shortening
- 2 cups sifted confectioners’ sugar
- 2 teaspoons vanilla extract

1. Set two racks in the middle of the oven. Preheat to 375°F.
2. In a food processor, or bowl of an electric mixer, thoroughly mix the flour, cocoa, baking soda and powder, salt, and sugar. While pulsing, or on low speed, add the butter, and then the egg. Continue processing or mixing until dough comes together in a mass.
3. Take rounded teaspoons of batter and place on a parchment paper-lined baking sheet approximately two inches apart. With moistened hands, slightly flatten the dough. Bake for 9 minutes, rotating once for even baking. Set baking sheets on a rack to cool.
4. To make the cream, place butter and shortening in a mixing bowl, and at low speed, gradually beat in the sugar and vanilla. Turn the mixer on high and beat for 2 to 3 minutes until filling is light and fluffy.
5. To assemble the cookies, in a pastry bag with a 1/2 inch, round tip, pipe teaspoon-size blobs of cream into the center of one cookie. Place another cookie, equal in size to the first, on top of the cream. Lightly press, to work the filling evenly to the outsides of the cookie. Continue this process until all the cookies have been sandwiched with cream.

*These are very sweet cookies--I definitely need to give them another go around before I get them to how they are supposed to be.  I made the wafers too big and flattened them to flat.  I also just spread the frosting on one cookie and then topped it with another.  Nonetheless, they were gone within a day!
