11. Using protein powder in a cake is always a good idea, because it lends a sweeter flavor without having lots of extra sugar. I’m not against sugar at all, but sometimes I like something less sweet. And the way you described this, ‘sweet and fluffy’ caught me right away!

    • Exactly! And a little less sweet means you can go CRAZY with toppings!!! 😉

12. Yumm- this sounds amazing Kalia! Cooking with zucchini always leads to something yummy in my opinion 🙂

    • I totally agree!! One of my favorite ingredients for sure.
