Preheat oven to 350. Line muffin pan with cupcake liners or grease with cooking oil spray. For the lentil puree bring the lentils and water to a boil. Cover and simmer for 7 to 9 minutes. Drain, reserving the liquid. Add 1/4 c. of the liquid back into the lentils. Puree in a blender or food processor; set aside. Beat the sugar, oil, and eggs together for 2 minutes. Add the lentil puree and vanilla to the creamed mixture. Mix for 1 minute. Sift the dry ingredients, add to the batter, and beat for 2 minutes on high speed. Pour into prepared cupcake pan and bak for 15-20 minutes or until top springs back when touched lightly (or toothpick inserted comes out clean). Remove from oven and place on cooling racks. Cool completely. Frost with your favorite icing.
