Red Velvet Cookies with Green Mint Chips

2 1/4 c. all-purpose flour

2 1/2 Tbl. cocoa powder

1 1/2 tsp. cornstarch

3/4 tsp. baking soda

1/2 tsp. salt

7 Tbl. unsalted butter, room temperature

6 Tbl. shortening

1 1/2 c. sugar

1 egg

1 egg yolk

1 1/2 tsp. white vinegar

1 1/2 tsp. vanilla

1 Tbl. red food coloring

1/2 c. white chocolate chips

3/4 c. green mint chips

Preheat oven to 375 degrees.  Combine flour, cocoa powder, cornstarch, baking soda and salt; set aside.  In the bowl of a stand mixer, beat together the butter, shortening and sugar until very pale and light and fluffy; about 4 minutes.  Add the egg and egg yolk and mix well.  Add the vinegar, vanilla and red food coloring and mix until fully incorporated.  Slowly add dry ingredients and mix until just combined.  Stir in 1/2 cup of white chocolate chips.  Roll about 1 1/2 Tablespoons of dough into a ball and press 6 green mint chips into the top, being careful not to flatten cookie.  If cookie does get flattened, roll back into a ball.  Repeat with remaining dough.  Bake for 8-9 minutes, they will look underdone.  Yield: 3 dozen cookies.

Jenn's Notes: I ended up adding a few extra drops of red food coloring, because after I added the dry ingredients, it didn't look as red as I wanted.  I baked my cookies for 9 minutes and they were perfect.  I did chill my dough for a few hours before I got around to baking them.  These cookies are so soft and chewy and the flavor is outstanding.  I got exactly 3 dozen cookies.
