No long pre-amble:

• 4 small avocados- puréed
• 1 cup cocoa
• ⅓ cup sugar ( whatever kind you like)
• 1 teaspoon vanilla extract
• ½ teaspoon baking soda
• 2 eggs

Oven 350 degrees F
Lightly greased pan and bake for 30 minutes. Cool and chill before cutting.
The oops, I forgot:  Add 1/2 cup chocolate chips to the batter.
So, I tried to do that thing where you sprinkle the chips on top and then smooth it out once it has melted  – but apparently white and dark chocolate chips have different melting points and don’t play well together…
