Preheat oven to 375°.
Combine almond flour and next 6 ingredients in a medium bowl.
Mix together oil, eggs, honey, coffee, and vanilla paste in another medium bowl.
Add oil mixture to dry ingredients and stir until well-combined. Stir in dark chocolate chips.
Pour batter into lightly-greased muffins tins to fill 3/4-full.
Sprinkle tops with a dusting of turbinado sugar, if desired.
Bake at 375° for about 13 minutes, or until a pick inserted in the center of a muffin comes out clean.
