I love this recipe, and it's been my go-to before work breakfast for a few months now. I have been looking for a decently healthy replacement for the Starbucks Morning Muffin and this comes close (hence the added finishing sugar and pepitas on top). I have made it with both shredded apple and zucchini and I like them both, sometimes I use one of each if I double the recipe. They freeze beautifully, I just defrost for a few seconds and heat for a few seconds in the microwave. It is a forgiving recipe and your add in options are endless. I am playing with the spices. I do add more ginger, and maybe some other warm spices like clove and allspice but I haven't perfected what blend I like best.
