Orange Cake - Odd, yet delicious

I ran into this recipe for Orange Cake a while ago over on Elana's Pantry, and finally tried making it the other day.  It's very good, but cries out for a decent paleo chocolate icing to accompany it.  I'm researching options there...

Ingredients

• 2 small oranges, seedless variety
• 4 large eggs, room temperature
• 0.75 cups honey
• 2 cups almond flour
• 0.5 tsp salt
• 1 tsp baking soda

Instructions

1. Wash the oranges well, and remove the produce stickers if present.
2. Boil the oranges (yes, whole) in a pot full of water for about 90 minutes, until nice and soft, then let them cool.
3. Preheat an oven to 375F.
4. Process the oranges in a food processor until nice and smooth.
5. Gradually add all of the other ingredients, "pulsing" the food processor to combine.
6. Grease a 9 inch cake pan (okay, I used an 8 inch pan - still worked just fine).
7. Pour all the batter into the pan.
8. Bake for 50 to 60 minutes, until the proverbial toothpick comes out clean.
9. Allow to cool for at least a couple of hours in the pan.
10. (Still to come) Ice your cake with a nice paleo chocolate frosting...
