Preheat your oven to 350 degrees F and spray a 12 silicone donut pan with non stick spray and set aside.
In a medium bowl, whisk together your flour, 1 cup of sugar, baking powder, salt and set aside.
Then in a large bowl, whisk together your melted butter, eggs, milk, and vanilla extract until combined.
Add your bowl of dry ingredients into the wet ingredients and whisk until combined.
Fill your donut pan about 3/4 full with your donut batter. Bake in your preheated oven for 10 – 12 minutes.
Remove from oven, let cool for 5 minutes, then remove donuts from pan.
Place your remaining sugar in a plastic bag or in a bowl.
Place your warm donut in the sugar and evenly coat. Enjoy!
