Preheat oven to 400°F (200°C).
In a bowl, whisk together flour, sugar, poppy seeds, baking powder, baking soda and salt.
Separately, whisk together yogurt, coconut oil, lemon zest, and eggs.
Add dry ingredients to wet until just combined—don’t overmix!
Stir in the grated zucchini last. I recommend first placing grated zucchini in a clean kitchen towel or paper towels and squeezing to remove excess moisture!
Transfer to a jumbo muffin tin, sprayed with cooking spray. (I use 2 scoops of a regular-sized ice cream scoop, or about ½ cup. Fill the muffins almost to the top, but not all the way!)
Bake for 5 minutes at 400°F (200°C), and then lower to 350°F (180°C) and bake 20-22 minutes. They are done when tops are golden and a toothpick comes out clean.
Cool slightly before popping out of the tin and enjoying!
Yields 6 jumbo healthy lemon poppy seed muffins.
