INGREDIENTS
For the cookies:
1 1/4 cups
all-purpose flour
1/2 cup
unsweetened
Dutch process cocoa powder
1 tsp
baking soda
1/4 tsp
baking powder
1/4 tsp
salt
1 cup
sugar*
10 tbsp
unsalted butter, at room temperature
1
large egg
For the filling:
4 tbsp
unsalted butter, at room temperature
1/4 cup
vegetable shortening
2 cups
confectioners’ sugar, sifted
2 tsp
vanilla extract
*The range of sugar called for here allows you to make these cookies as sweet as you like (or not). To make it closer to a store-bought Oreo, use 1 cup. For a sweeter cookie, use the full 1½ cups. I split the difference and used 1¼ cups.
