Hi G. - I get Timbercreek Organics and for awhile every box had zucchini in it. My kids hate it cooked so, I started cutting it in slices as soon as I got it and put in in ziplocs in the freezer. We are dairy, egg and nut free here and the zuccini has worked great as an egg replacer : ) I just made cupcakes for a birthday party we were going to. I just use what I have on hand. I used a regular chocolate cake mix and skipped all the added requirements. In a blender, I put probably 2 cups of zuccini and a cup or two of V-8 fusion (I usually use rice milk)and blended well to a smoothie consistency. I poured that into a bowl with the cake mix and blended till it was cake batter consistency. I then used Ener-G (egg replacer) to help it rise (two "eggs" worth).
I use zuccini in smoothies all the time too... especially when out of spinach. We make "Monster" smoothies... and the kids beg for more. 1 cup of frozen zuccini slices, 1 frozen banana (in chunks), 1/4th of a fresh pineapple and enough "milk" to get it to blend in the blender. Depending on how much milk you use, you can make it like ice cream or a smoothie. Whatever is left, pour into popsicle forms or ice cube trays for a frozen treat later.
You can also steam your zuccini and then (cooled) put it in the blender and pour in ice cube trays. Once frozen, transfer to ziploc bags. You can then sneak a little zuccini into most anything. : )
Hope that helps!!
