The huge chocolate chocolate chip cookies -- one of the food stars of my car's 18th birthday.

Ingredients Step
Preheat oven to 410 degrees Fahrenheit. Line cookie sheets with parchment paper.
1 c. butter, cold, cubed
1 c. brown sugar
½ c. white sugar
Cream in a mixer for at least 4 minutes (time it!).
2 eggs
1 t. vanilla
Mix in. Mix for at least 1 minute, scraping as needed.
½ c. (60 g) cocoa powder
1 c. (120 g) cake flour
1½ c. (180 g) AP flour
1 t. cornstarch
3/4 t. baking soda
½ t. salt
Combine in a large bowl. Then fold into the wet ingredients, leaving some streaks because there's more dough working to come.
1.75 c. chocolate chips
2 c. mini marshmallows
3/4 c. cashews, chopped
Stir in.
Roll the dough into 5-6 oz. balls (roughly baseball size). Press a few extra chocolate chips and marshmallows into their tops.
Bake 9-11 minutes at 410 degrees. After removing from oven, use a silicon spatula to press the edges to the center to make each cookie round again. Let them rest on the pan for 15 minutes, then remove from pan to cool fully on a rack.
