3 cups all-purpose flour
1 tablespoon baking powder
1 tablespoon baking soda
1 tablespoon ground cinnamon
1 teaspoon salt
1 ½ cups (3 sticks) butter, at room temperature
1 ½ cups granulated sugar
1 ½ cups packed light-brown sugar
1 tablespoon vanilla
3 cups semisweet chocolate chips
3 cups old-fashioned rolled oats
2 cups unsweetened flake coconut
2 cups chopped pecans (8 ounces)
Heat oven to 350 degrees.
Mix flour, baking powder, baking soda, cinnamon and salt in bowl.
In a very large bowl, beat butter with an electric mixer at medium speed until smooth and creamy. Gradually beat in sugars, and combine thoroughly.
Add eggs one at a time, beating after each. Beat in vanilla.
Stir in flour mixture until just combined. Stir in chocolate chips, oats, coconut and pecans.
For each cookie, drop 1/4 cup dough onto ungreased baking sheets, spacing 3 inches apart.
Bake for 15 to 17 minutes, until edges are lightly browned; rotate sheets halfway through.
Remove cookies from rack to cool.
