Preheat oven to 375 degrees. Prepare donut pan by greasing or spraying with non-stick spray and set aside.
Fluffy Chocolate Donuts
Whisk the the flour, sugar, cocoa powder, and baking soda together in a medium bowl and set aside.
In a small bowl, whisk together the Greek yogurt, egg, almond milk, oil and vanilla extract.
Add the wet ingredients into the dry until just combined using a wooden spoon.
Pipe with a pastry bag or cut a ½ inch hole into a corner of a baggie and pipe into donut pan.
Bake for 8 minutes or until the tops spring back when you touch them.
Let donuts cool in the pan before glazing.
To make the glaze
In a microwaveable dish, combine the sugar, milk, and vanilla and whisk until well combined.
Microwave for 20-40 seconds and stir. The lumps should be melted.
Dunk the donuts in the glaze to fully coat and place on a wire rack to set.
Notes
If you don't have a donut pan, you can always use a muffin pan and glaze the tops afterwards. Adjust your time, depending if you make mini or regular muffins.
