In a medium mixing bowl, combine the oil and honey or maple syrup and beat together with a whisk. Add the eggs and beat well, then add the yogurt, vanilla and lemon zest. Mix well. (If the coconut oil solidifies in contact with cold ingredients, gently warm the mixture in the microwave in 30 second bursts.)
In a large mixing bowl, combine the flour, baking powder, baking soda and salt. Blend well with a whisk.
Preheat the oven to 350 degrees Fahrenheit. If necessary, grease all 12 cups on your muffin tin with butter, coconut oil or cooking spray (my pan is non-stick and doesn’t require any grease).
