In a food processor add the dates and process until smooth (approximately 2 minutes on high setting).
Place the dates and coconut water into a pot.
Cook on low for 5 minutes. This will plump (soften) the dates where they will blend into the muffin.
In a large bowl add the flour, sugar, baking powder, and cinnamon, make a well in the center.
In another bowl, add the dark brown sugar, eggs, and sunflower oil. Whisk this mixture until well blended.
Pour the egg mixture into the center open well in the larger bowl.
Then add the plumped dates and coconut water. Mix this mixture well.
Scoop into a mini muffin pan, sprayed with an oil to prevent sticking.
Place in the oven and bake 15 minutes at 350.
Remove muffins, cool on a wire rack, and sprinkle the top with powdered sugar. Enjoy!
