Moist Cocoa Lentil Cake

I'm not a huge fan of lentils - or more likely - I haven't found a recipe that makes them taste good yet.  Or I hadn't...until today:

I still haven't discovered a savory recipe that makes me crave lentils, but this cake was very good, very moist, and totally did not taste like lentils.

Moist Cocoa Lentil Cake

2 cups boiling water
2/3 cup washed lentils
1/4 tsp salt
----------------------------
1 cup oil
1 1/2 cups sugar
1 tsp vanilla
 4 large eggs
2 cups sifted flour
4 TBS cocoa
1 1/2 tsp soda

1/2 tsp salt

Add lentils and salt to boiling water. Cover and simmer for 40 minutes. Drain, reserving liquid. Add 1/2 cup liquid back to lentils. Make puree in blender or food processor. Preheat oven to 350 degrees. Grease and flour a 9x13 inch pan. Mix sugar, oil, eggs and beat well for 2 minutes. Add vanilla and pureed lentils to creamed mixture. Sift and add remaining ingredients. Beat for an additional 2 minutes. Pour into prepared cake pan. Bake for 30-35 minutes. Cool and frost.
