Preheat the oven to 375° and line a muffin tin with parchment cups.
In a large bowl, whisk together the olive oil and coconut sugar until mixed well. Add in the eggs and mix until well combined and then add in the milk and vanilla.
Once the wet ingredients are mixed well, add in the almond flour, all purpose flour, baking powder, salt and cinnamon. Mix until well combined as there shouldn't be any lumps.
Fold in the blueberries carefully so you don't break them.
Fill each muffin tin to the top and sprinkle a little extra coconut sugar on top if you like.
Bake for 25 minutes in the preheated oven. A toothpick should come out clean with maybe a few crumbs on it.
Notes
To make these muffins dairy free, substitute oat or almond milk for dairy milk.
