Place dates in a microwave safe container along with 1 cup of water and microwave on high for 2 minutes. Drain off water.
Place softened dates and chickpeas in food processor and process until mostly smooth (you will need to scrape down the sides 1 or 2 times). Add in rest of the ingredients except blueberries and process until a batter forms.
Stir in blueberries. Scoop into greased muffin tin (I use a Misto) and bake on 350 degrees for 20-25 minutes or until toothpick comes out clean.
