    How Do You Add Zucchini To Cake?

    There are two traditional ways to add zucchini to baked goods.

    1. blending (preferred method)
    2. grating

    How to Blend or Grate Zucchini?

    1. Cut of ends of zucchini
    2. chop into chunks
    3. place in blender
    4. Pulse until it's fine, but not liquid.
    5. DO NOT ADD WATER

    Zucchini has enough liquid that you do not need to add any additional water. If your blender needs a little help at first use a spatula to push down the vegetable. Once the blades hit the flesh it'll take off fast into liquid.

    What is the Best Frosting for Chocolate Zucchini Cake

    The original recipe calls for a cream cheese glaze on a bundt ban, which a rich indulgent chocolate frosting would be amazing also.

    How To Make Cream Cheese Frosting

    1. In a stand mixer with the paddle attachment, combine the butter and cream cheese and beat on medium speed until smooth, about 1 minute.
    2. With the mixer on low, gradually add the powdered sugar, one cup at a time, until incorporated.
    3. Keeping the mixer on low, add the milk, vanilla and salt.
    4. Turn the mixer to medium and beat the frosting for 3-5 minutes, or until it is light in color and texture (it will be white in color).

    FAQ'S

    Do I have to add Chocolate Chips?

    You do not! You can omit the chocolate chips and it will still be deliciously chocolatey.

    What are the best chocolate chips to use?

    You can use your favorite, I'm partial to milk chocolate but for a more rich chocolate flavor add semi-sweet or dark chocolate chips.

    How do I store zucchini cake with cream cheese frosting leftovers.

    Any cream cheese frosting should be refrigerated. So keep it in an air tight container in the fridge. In the fridge it will keep for 1-2 weeks.

      How much orange in the cake? How much salt in the frosting? Frustrating as I’m now making frosting so I guess I won’t be adding salt just as I didn’t add orange to cake mix.

        Hi Sally, I think there is an error in the recipe card that I'll correct right now. There is not orange in the recipe or salt in the frosting.

      This is the best chocolate zucchini cake I have made.
      Instead of the orange flavour I use coffee ( about 2 teaspoons dissolved in a small amount of hot water, plus extra vanilla) and I only use 1 cup of choc bits.
      It is delicious as a dessert warm with cream and/ or ice cream ( cake just dusted with icing sugar.
      I also make a large slab as a birthday cake, topped with whipped cream, strawberries and/or raspberries and also make small cakes in muffin tins, great warm or cold, again no frosting. Cake freezes well.
      My grandson who is on the autism spectrum and would rather die than eat zucchini is a truly avid fan.
