Recipe found in: Delicious Family Favorite Magazine.
1 cup butter, melted and cooled
1 1/2 cups firmly packed brown sugar
1/2 cup granulated sugar
2 large eggs
2 egg yolks
1 tablespoon vanilla extract
3 1/4 cups all purpose flour
1 teaspoon salt
1 teaspoon baking soda
1 teaspoon baking powder
1 (11.5-ounce) bag semi-sweet chocolate chunks
1 cup mini semi-sweet chocolate morsels
In a large bowl, beat melted butter and sugars at medium speed with a mixer until creamy. Add eggs and egg yolks one at a time, beating well after each addition. Beat in vanilla.
In a medium bowl, whisk together flour and next 3 ingredients. Gradually add to butter mixture, beating until combined. Beat in chocolate chunks and morsels. Cover, and refrigerate for 2 hours or up to 3 days.
Preheat oven to 350 degrees. Line baking sheets with parchment paper.
Using a 1/4 cup spring-loaded scoop, drop dough, 2 inches apart, on prepared pans. Bake for 12 minutes or just until edges of cookies are browned and tops are starting to brown.
Let cool on pans for 2 minutes. Remove from pans, and let cool completely on wire racks. Store cookies in airtight containers up to 3 days, or freeze in resealable plastic bags up to 1 month.
