Spinach Chocolate Muffins - Very Good!

Trying to increase the vegetables in our diets. Tried this first with no cocoa and it was an awful green colour that no teen would try! Then I added a little cocoa and it was an unappetizing brownish green - like a bad hair dye! Tasted good but looks make a difference! A little more cocoa and sugar and they looked and tasted great!  

Spinach Chocolate Muffins
2 cups whole wheat flour (you can use white)
1/4 cup cocoa
1 1/2 teaspoon baking powder
1/2 teaspoon baking soda
1 tsp. cinnamon
1/2 tsp. allspice
1/2 teaspoon salt
1 egg
1/4 cup cooking oil
1/2 cup sugar plus 2 tablespoons
1 cup frozen chopped spinach - packed
1/2 cup milk
1/2 cup chocolate chips
Method
Measure into mixing bowl and wisk together the flour, cocoa, baking powder, baking soda and spices. Set aside.
In blender or food processor add the oil, milk and spinach. Process on high until well mixed/pureed. Add the egg and sugar and blend together. Pour over the dry mixture and chocolate chips and mix with fork until just blended - for best results do not over mix muffins. Fill 12 muffin cups and bake at 400 for 15 minutes until tooth pick inserted comes out clean.
Cool and serve.

The first batch with a little less cocoa came out a bit greenish not as appealing - 

Once on the left has the extra cocoa - looks much nicer!
