I adapted this one from Jezwyn over at Girl Gone Primal:
1 ripe avocado
1 T pure cocoa powder
1 t cinnamon
1/2 T pure maple syrup or honey (to taste)
Mash the avocado in a bowl, then thoroughly mix in the spices and sweetener. I use my potato masher in a flat-bottomed bowl when I am in a hurry (hence the green bits). If you are inclined, throw it all in the food processor and whiz until smooth.
The texture and appearance is similar to chocolate pudding and I heartily market it as such.
I always serve this dip in a small dish for dipping with apple slices, pear or berries. My kids generally will not touch avocado, but they love this stuff! For little ones who cannot yet do apple pieces, I will spoon-feed this with a side of apple sauce or grated raw apple, or banana pieces.
