Preheat oven to 350°.
Place dry ingredients (flours, sugars, cocoa, and baking soda) in a medium bowl and mix together.
In a separate bowl, mash the avocado; add wet ingredients (egg, vanilla, syrup, milk); mix wet ingredients together either by hand or with a mixer.
Combine wet and dry ingredients into one bowl and mix together.
Once mixed, add chocolate chips.
Place dough on a parchment-lined cookie sheet. I used small-medium sized balls and then smashed them down a bit with a spatula so they were a bit more flat.
Bake for approximately 8 minutes so that they are cooked through but still soft.
