Preheat oven to 350° and grease donut pan with cooking spray. (Don't forget the centers where the donut hole is!)
In a large bowl, whisk to combine almond flour, granulated sugar, baking powder, and salt.
In a medium bowl, whisk together melted butter, cream, eggs, and vanilla. Fold wet ingredients into dry ingredients until just combined. Fill each donut mold ¾ of the way full with batter.
Bake until donuts are golden in color and pulling away from sides of the pan, 15 minutes. Let cool completely in pan before removing.
Meanwhile, make chocolate glaze: Sift powdered sugar and cocoa powder together into a large bowl. Add water and vanilla and whisk until smooth.
Fit a cooking wrack into a medium sheet tray, then flip cooled donuts out onto cooling wrack. Pour glaze over donuts and let set 10 minutes before serving.
