Vegan "Fauxreo" Chocolate Sandwich Cookies - cooking recipe

Ingredients

FOR COOKIES
3/4 cup vegetable shortening
1 cup sugar
2 teaspoons vanilla extract
1/2 cup soymilk
1 1/2 cups all-purpose flour
3/4 cup Dutch-processed cocoa powder
2 teaspoons cornstarch
1/2 teaspoon salt
1/4 teaspoon baking soda
FOR FILLING
1/4 cup margarine, softened
1/4 cup vegetable shortening
2 3/4 cups powdered sugar
1 teaspoon pure vanilla extract

Preparation

FOR COOKIES: Cream the shortening and sugar on medium speed. When light and fluffy add the vanilla and milk. Add remaining ingredients and mix until the dough holds together.
If it's hot or warm in the kitchen or outside, chill the dough in the freezer for 10 minutes. Preheat oven to 325\u00b0F Divide the dough into four pieces and roll each into a ball. Place a piece of parchment paper on a flat surface, flattening the balls of dough onto the parchment. Place another piece of parchment paper on top and then roll the dough to about 10″ in diameter and about 1/8″ thick.
Cut circles about 1 1/4″ across from the dough with a cookie cutter and refrigerate if the excess dough doesn't lift away easily enough. Transfer the parchment onto the cookie sheet. Bake 12 minutes, and repeat with remaining dough, using scraps at the end until all the dough is used up.
FOR FILLING: On medium-high speed, cream the margarine and shortening. Add the sugar in about 1/2 cup increments until thoroughly combined; it should be stiff and pliable. Add in the vanilla. Refrigerate until ready to use. Roll the filling into round, about 3/4″ pieces and smash until roughly cookie-sized, then sandwich between two cookies.
