Preheat oven to 375°. Mix Country Crock® Spread, granulated sugar, light brown sugar, egg, egg yolk and vanilla in large bowl until well mixed. Stir in flour, baking powder, salt and baking soda until blended. (Dough will be soft and creamy.)
Add your favorite mix-ins in any combination, and mix until every spoonful of dough has some of the delicious mix-ins.
Drop dough by rounded tablespoonfuls on ungreased baking sheets 3-inches apart.
Bake 10 to 12 minutes until edges are lightly golden. Cool 1 minute on wire rack; remove from sheets and cool completely.
Add toppings and decorations if desired.
