My friend makes these and they are amazing! I can eat like 4 at a time...
1 Devils Food Chocolate Cake Mix
2/3 cup shortening
Mix everything together and roll into 1 tsp. balls. Bake @ 350 degrees for 8-10 minutes (do not over bake). You may want to double the batch because one cake mix doesn't make very many cookies.
3 ounces cream cheese
1/4 tsp. vanilla
2 cups powdered sugar (may need more depending on consistency)
2 Tbsp. butter
Place the filling between two chocolate cookies to make homemade Oreos.
