Get your oven ready by preheating it to 350°F (177°C). Lightly spray a donut pan with nonstick spray and set it aside.
In a big bowl, gently whisk together your gluten-free flour, baking soda, baking powder, cocoa powder, sweetener, and salt. Sifting these dry ingredients beforehand helps prevent any lumps for a super smooth batter!
Now, add the egg, melted vegan butter, almond milk, and vanilla extract to the dry mixture. Stir gently until everything is just combined and perfectly smooth – remember not to overmix! The batter will be delightfully thick.
Carefully spoon the donut batter into your prepared donut pan, filling each cavity almost to the top. A piping bag can make this step even easier and neater!
Bake for about 10-12 minutes, or until a toothpick inserted into the center of a donut comes out clean. This means they're perfectly baked!
Let the freshly baked donuts cool in the pan for 5 minutes. Then, gently transfer them to a wire rack to cool completely for another 10-15 minutes. This cooling time is key before you add the glaze.
While your donuts are chilling, it's time to make the easy glaze: Sift the powdered sweetener into a medium bowl, then stir in the thick non-dairy milk and vanilla extract until you have a smooth, luscious glaze.
If your glaze seems a little too thin, simply add a tiny bit more powdered sweetener. If it's too thick, a tiny splash more milk will get it to the perfect dippable consistency!
Once the donuts are fully cooled, dip each one into the glaze, letting any extra drip off. Place them back on the wire rack (over a baking sheet to catch any drips) to allow the glaze to set.
For a truly decadent, thick glaze, pop the glazed donuts into the freezer for 5 minutes to help the first layer set. Then, repeat the dipping process 1-2 more times. Enjoy your homemade, healthier chocolate donut delight!
