INGREDIENTS:
-1 cup butter
-1¼ cups dark brown sugar
-½ cup granulated sugar
-1 egg
-1 egg yolk
-1 teaspoon pure vanilla extract
-2 cups flour
-1 cup rolled oats (not quick cooking)
-½ teaspoon baking soda
-½ teaspoon salt
-¼ teaspoon ground cinnamon
-1 cup white chocolate chips
-1 cup chocolate chips (I use half milk, half semisweet)
INSTRUCTIONS:
1-In a medium saucepan, melt the butter over medium heat until melted. Remove from the heat.
2-Add the dark brown sugar and granulated sugar and stir until smooth. Chill the mixture for 10 minutes.
3-Remove from the refrigerator and stir in the egg, egg yolk, and vanilla.
4-Add the flour, oats, baking soda, salt, and cinnamon and mix together.
5-Stir in the white chocolate chips and chocolate chips.
6-Roll by hand into 24 medium-size balls or use a scoop, and place on a light-colored cookie sheet. (I wanted a little bit smaller cookie but still did generous scoops and got closer to 40 cookies).
7-Chill for 30 minutes.
8-Preheat the oven to 325 degrees F. Remove the cookies from the refrigerator and bake for 12 to 14 minutes.
