Preheat oven to 350 degrees F. Line a muffin pan with muffin papers.
Whisk together the flour, coconut sugar, Truvia, cocoa powder, baking powder, salt, and baking powder until well combined.
In a separate bowl, whisk together the oil, milk, flaxmeal, vinegar, and vanilla.
Using a hand blender, blend the dry ingredients into the wet ingredients until blended. Portion the batter into muffin tins (they will be about 2/3 full).
Bake for about 18 minutes or until toothpick inserted in center is no longer wet (they may still be crumbs on it).
Cool on wire rack completely before frosting. Enjoy!
