Preheat oven to 350 degrees.
Place the drained dates in the bowl of a food processor and process until pureed. If you don't have a food processor, use a blender to puree the dates and then proceed with mixing the remaining ingredients in a bowl.
Add the two flours, vanilla, oil and baking soda to the food processor and mix until the dough comes together.
Remove the cookie dough to a bowl and mix in the chocolate chips.
Divide the dough into 12 balls and flatten them between your fingers before placing on a parchment- or foil-lined baking sheet.
Bake for 10-12 minutes. If you want softer, chewier cookies, get them out of the oven after 8-10 minutes. For more crunchy, darker cookies, cook a couple of minutes longer.
