Preheat oven to 375 degrees F. Grease a 12 cup muffin pan. I use an olive oil spray.
In a medium bowl, stir together the dates, boiling water, baking soda and vanilla extract. Let the mixture sit for 15 minutes.
In another medium bowl, mix the almond flour, tapioca flour, coconut flour, and, salt.
In a large bowl, whisk or beat together the olive oil, coconut sugar, and eggs until smooth. Stir in the date mixture. Add half of the dry flour mixture and mix, then add the other half and mix again. Let the batter sit for 5 minutes. Spoon the batter into the greased muffin tin.
Bake for 17-20 minutes, or until a toothpick comes out clean. Let the muffins cool in the pan for 5 minutes before removing them. I use a knife to push along the edges of the muffins and then lift each muffin out.
