Heat oven to 300 degrees F. Line baking sheets with parchment or use a silpat.

Step 2

In a stand mixer or with an electric mixer in a large bowl, cream the butter, sugar, and brown sugar on medium speed for about 2 minutes.

Step 3

Add eggs, vanilla, and lemon juice. Beat for about 2 minutes or until light and fluffy, scraping down the sides of the bowl.

With mixer on low speed, add in the flour, oats, baking soda, salt, and cinnamon, mixing until just blended. Do not over mix.

Step 5

Remove bowl from mixer and stir in chocolate chips and walnuts.

Step 6

Portion out about 3 TBSP dough per cookie (A small ice cream scoop works well) and place on prepared baking sheet about 2 inches apart.

Step 7

Bake for 20 to 23 minutes, or until edges start to get golden brown and center is still soft.

Step 8

Remove from oven and cool on baking sheet for about 1 hour. Store in airtight container. These baked cookies freeze well.
