Zucchini Brownie

  • 1/4 c vegetable oil
  • 3/4 c white sugar
  • 1 tsp. McCormick® vanilla extract
  • 1 c all-purpose flour
  • 1/4 c unsweetened cocoa powder
  • 1 tsp. baking soda
  • 1/2 tsp. salt
  • 1 c zucchini finely grated and drained

Zucchini Chocolate Chip Cookies

  • 1/2 c butter room temperature
  • 1 c granulated sugar
  • 1 egg beaten
  • 2 c all-purpose flour
  • 1 tsp. baking soda
  • 1/2 tsp. salt
  • 1 c zucchini finely grated and drained
  • 1 c semi-sweet chocolate chips
  • 16 Oreos or as many as you need to fit your pan


Zucchini Brownie

  • In a large bowl, mix together the oil, sugar and vanilla until well blended.
  • Combine the flour, cocoa, baking soda and salt. Stir into the oil mixture.
  • Fold in the zucchini.

Zucchini Chocolate Chip Cookies

  • In the bowl of your stand mixer, cream your butter and sugar together until light and fluffy.
  • With the mixer on low, add the egg.
  • Turn mixer off and add in flour, baking soda, and salt into the butter mixture. Turn the mixer on low and allow it to incorporate ingredients. Remove when dough has almost come together, about 30 seconds to 1- minute later. It will be very dry.
  • Remove bowl from mixer and add in zucchini and chocolate chips. Stir by hand until combined.


  • Prepare a 9x9 inch square pan with baking spray and/or parchment. If you have a springform pan that is great.
  • Prepare cookie dough (and chill) then prepare brownie batter.
  • Cover bottom of pan with chocolate chip cookie dough. If dough is chilled, you can flatten it with a drinking glass to ensure an even layer. (If dough is room temperature it should be easily spreadable with your hand.)
  • Place Oreo's on top of cookie dough. Get as many as you can into the pan without overlapping.
  • Pour brownie batter over Oreo's and cookie dough.
  • Bake for 30-45 minutes at 350 degrees F, or until center is not raw.
