*I have made these muffins using a full 5-ounce package of spinach, which does make for a slightly more obvious spinach flavor. It is, however, a great way to get a worthy serving of leafy greens for those who don’t mind some noticeable flavor.
**I have reduced the maple syrup to as little as ⅓ cup (106g). I like them this way, especially with a spread of peanut or almond butter. (I highly recommend that tasty addition, which will also mask any spinach flavor for those who go heavy on it, as mentioned above. ) As is, however, the reduced maple syrup version was not quite sweet enough for my son. Those who are looking to reduce added sweeteners as much as possible, however, may be quite happy with this version. Conversely, those who prefer a sweeter muffin can use the prescribed ½ cup plus 2 tablespoons.
Want more protein? I made one batch with the addition of 1 scoop of vanilla protein powder with excellent results. If you’d like to add more, I recommend doing so incrementally.
