Note on using lentils: If using canned lentils, drain first and omit salt; if using dry (my preference is dry red lentils) measure 1/3 cup rinsed lentils into saucepan, add 2/3 cup water and bring to boil; reduce heat and simmer 20 minutes (may need to add a small amount of water) cool and measure.
Mash lentils with a fork in mixing bowl.
Add eggs, oil, sugars, and vanilla extract to lentils.
Mix just to combine.
Mix flour, baking soda, baking powder, salt, cocoa and cinnamon in separate bowl.
