Preparation Steps

• Preheat oven to 350°F. Line 2 baking sheets with parchment paper.
• In a large bowl, beat softened butter, brown sugar, and granulated sugar until light and creamy, about 2 minutes.
• Beat in eggs one at a time, then mix in vanilla until smooth.
• In a separate bowl, whisk flour, baking soda, salt, and cinnamon.
• Add dry ingredients to the wet mixture and mix on low just until a few streaks of flour remain.
• Fold in oats, chocolate chips, and walnuts until evenly distributed.
• Scoop dough into 2 tbsp portions and place 2 inches apart on prepared sheets.
• Bake 10 to 12 minutes, until edges are golden and centers look just set.
• Cool on the sheet for 5 minutes, then transfer to a wire rack to cool completely.
• For thicker cookies, chill scooped dough for 30 minutes before baking.
