Favorite Recipe - Cowboy Cookies

Since I've been asked for this recipe many times in the last week or so, I figured this would be the one that I'd use for today's prompt.

They are the bestest and biggest cookies EVER.

Laura Bush's Cowboy Cookies 

3 cups all-purpose flour 
1 tablespoon baking powder 
1 tablespoon baking soda 
1 tablespoon ground cinnamon 
1 teaspoon salt 
1-1/2 cups (3 sticks) butter (at room temperature) 
1 1/2 cups granulated sugar 
1-1/2 cups packed light-brown sugar 
3 large eggs 
1 tablespoon vanilla extract 
3 cups semisweet chocolate chips 
3 cups old-fashioned rolled oats 
2 cups sweetened flake coconut 
2 cups chopped pecans (8 ounces) 

Preheat oven to 350 F. Mix flour, baking powder, baking soda, cinnamon and salt in bowl. In 8-quart bowl, beat butter on medium speed until smooth and creamy, 1 minute. Gradually beat in sugars; beat to combine, 2 minutes. Add eggs, one at a time, beating after each. Beat in vanilla extract. Stir in flour mixture until just combined. Add chocolate chips, oats, coconut and pecans. For each cookie, drop 1/4 cup dough onto ungreased baking sheets, spacing 3 inches apart. Bake for 17 to 19 minutes, until edges are lightly browned; rotate sheets halfway through. Remove cookies from rack to cool. Makes about 3 dozen cookies. 

NOTE: For 6 dozen smaller cookies, use 2 tablespoons dough for each. Bake at 350 F for 15 to 18 minutes.
