How This Recipe Came To Be:
This recipe came to be toward the fall. Gardening season was coming to an end so I broke down, pulled all remaining veggies and froze them. Over the next couple of weeks I kept asking myself what to do with the zucchini. I had the beginnings of a recipe in mind, hoping to use Noosa Yoghurt (my all-time favorite yoghurt, EVER!), apples and warming spices.
On my next grocery run I made a point to find the perfect Noosa Yoghurt to pair with my idea. And after coming across their Apple Cinnamon flavor, I knew it was the perfect fit.

A couple of test runs later and the recipe came together beautifully. These muffins have all the fall/holiday vibes going on, along with being light, moist, and perfectly crumbly from the crazy good cinnamon topping. Did I mention “healthy” from the zucchini! Everyone who has sampled this so far has raved about it, and I am extremely proud of that.

It certainly makes Chrsitmas cooking for my family a more pleasant task this year knowing you (Naomi) are going to make some of your favorite recipes, this being one of them! She’s even agreed to bring the yoghurt since I can’t find the particular flavor called for in the muffin recipe. On the morning these are made I plan to make quiche. It should be a perfect breakfast!
Oh Patricia, you are too sweet! I can’t wait for breakfast on Christmas morning…great food and good company! What more could you ask for?!?
