Step 1

With a stand or handheld mixer, cream the butter and sugars together at medium speed until light and creamy. Add egg, vanilla, molasses and lemon juice scraping down the sides as needed. Set aside.

Step 2

In a medium-sized bowl, add all of the dry ingredients except rolled oats and whisk to combine. Add oats and whisk together.

Step 3

With the mixer running on low, slowly add the dry ingredients to wet ingredients. The dough will be quite thick and you will have to finish mixing with a wooden spoon. Add apples and walnuts and mix until combined. Cover tightly and chill dough for at least 4 hours.

Step 4

Preheat oven to 350°F degrees. Line a cookie sheet with parchment paper or nonstick baking mat. Drop dough by rounded tablespoonfuls, 3 inches apart, onto prepared cookie sheet, 8 to a sheet (keep remaining cookie dough in the refrigerator).

Step 5

Bake at 350°F for 11-15 minutes or until golden around the edges and center is just set. Let stand for 3 minutes before removing to wire racks. Store cooled cookies in an airtight container.
