Preheat the oven to 350 degrees Fahrenheit and line two baking sheets with parchment paper.

In a small bowl, add the coconut flour, erythritol, cocoa powder, baking powder, and salt.

In a large bowl, whisk together the melted coconut oil, almond milk, eggs, vanilla extract, and stevia extract.

Sift the dry ingredients into the bowl with the wet ingredients.  Whisk until the batter is completely even.

Use a cookie scoop to portion 12 scoops onto the prepared pans.  Bake for ~9 minutes, or until the surface springs back when tapped.  Let cool completely.

Frost half of the whoopies with your frosting of choice (I used Cream Cheese Frosting!), then sandwich the remaining whoopies on top.  Serve and enjoy!
