"Oreo" Cookies

One of my husbands favorite cookies are Oreo's. I try to make desserts that are pleasing to my family, so when I saw this recipe, I knew I wanted to make it for my husband. They turned out okay. I wish they were a softer cookie because I prefer soft cookies, but they wouldn't resemble oreos if they were soft. I think that I ate more of the dough than the actual cookie, but my husband liked them. Note: Make sure you create room in your fridge for the dough before beginning.

For the Dough:
1 1/3 c. Dutch-process cocoa powder
1 1/2 c. all purpose flour, plus more for dusting
1/4 tsp salt
2 sticks unsalted butter, softened
2 c sugar
2 large eggs
1 tsp vanilla extract

For the filling:
1 stick unsalted butter, softened
1/2 c. vegetable shortening
3 c confectioners' sugar, sifted
1 tsp vanilla extract

Directions:
1. Prepare the dough: Sift together the cocoa powder, flour and salt in a large bowl.
2 Using a mixer, cream the butter and sugar. Add the eggs one at a time, then the vanilla, incorporating each ingredient before adding the next. Add the dry ingredients and mix until just incorporated, scraping the bowl with the spatula.
3. divide the dough into 2 pieces; place one piece between 2 lightly floured sheets of parchment paper and roll into a 1/4" thick rectangle. Repeat with the other piece of dough. Refrigerate both rectangles, covered with parchment paper, until firm, at least 1 hour or up to several days.
4. using a 2" round cookie cutter, cut the dough into 64 circles. ( You can roll the scraps once.)
Place the cookies about 2 inches apart on an ungreased baking sheet and chill for 20 minutes. Preheat the oven to 325.
5. Bake the cookies until they are set and slightly darker around the edges, about 20 minutes. Cool completely on wire racks.
6. Meanwhile, prepare the filling: Using a mixer, cream the butter and shortening until fluffy. Beat in the confectioners' sugar and vanilla.
7. Flip half of the cookies upside down and top each with a level tablespoon of filling. Press the remaining cookies on top to make sandwiches.
