Advance preparation:
Soak lentils, rolled oats, 1 medjool (or 2 regular) dates and ground flaxseed in 2-1/2 cups water overnight.
Soak remaining 6 medjool (or 12 regular) dates in 3/4 cup water overnight.
To make the pancakes:
Blend lentil mixture in a high-powered blender until smooth, adding up to a 1/2 cup of water to achieve desired thickness.
Heat pan over medium heat and lightly wipe with oil. Pour about 1/4 cup batter for each pancake. Flip after 1-2 minutes.
To make the chocolate sauce:
Blend dates, soaking water, and cocoa (in a smaller high-powered blender if available). Add water for desired consistency.
Divide pancakes among 4 plates, pour chocolate sauce over pancakes, and top with berries (and maybe a teaspoon of unsweetened coconut flakes if desired).
