Spinach Muffins

I saw this on Pinterest, posted by The Green Forks, but I've made a couple of key changes for myself. The original recipe calls for fresh spinach but I use frozen. 

1/2 package of frozen spinach, thawed

1/2 cup banana

2 cups flour

2 tsp baking powder

1/2 tsp baking soda

1 1/2 tsp cinnamon

1/2 tsp salt

3/4 cup sugar

2 tsp vanilla

1/4 cup oil

1/4 to 1/2 cup water

Preheat oven to 350 degrees, and prepare a 12-cup muffin tin.

Thaw frozen spinach but do not drain!

Whisk together the dry ingredients, set aside.

In blender, place oil, spinach, banana. Blend until completely smooth. Add vanilla.

Pour puréed mixture into dry ingredients, add 1/4 cup water, folding together until entirely combined. As you start to mix this, you'll be able to tell if it needs a bit more water.

Fill muffin cups 3/4 full, bake for 18-20 minutes.

Notes:

Very tasty with apple or applesauce instead of banana.

Also yummy with chocolate chips!
