Step 1

Preheat oven to 375°F. Line a sheet pan with parchment paper.

Step 2

In the bowl of an electric mixer, beat the butter, sugar, and brown sugar until light and creamy, 3-5 minutes. Stop to scrape down then bowl once or twice.

Step 3

Add the egg, vanilla, and zucchini, beating after each and scraping down the bowl at least once.

Step 4

Add the flour, baking soda, salt and cinnamon and mix until almost combined. Add the chocolate chips and walnuts and mix briefly until incorporated.

Step 5

Portion equally (I use a #40 1½ Tbsp scoop) and roll into rounds. Space evenly about 4 inches apart on prepared sheet pan.

Step 6

Bake for 9-11 minutes until edges are golden and top is set but not at all browned.

Step 7

Let cool on the sheet pan for 5 minutes, then transfer to a wire rack to cool completely.
