Preheat the Oven:

• Preheat your oven to 350°F (175°C). Grease a donut pan or lightly coat it with non-stick spray.

2. Make the Donut Batter:

• In a medium bowl, whisk together the all-purpose flour, granulated sugar, baking powder, and salt.
• In another bowl, whisk together the melted butter, egg, skim milk, and vanilla extract until smooth and fully combined.
• Gradually add the wet ingredients to the dry ingredients, stirring just until combined. Be careful not to overmix.
• The batter will be thick.

3. Bake the Donuts:

• Spoon the batter into the donut pan, filling each cavity about 2/3 of the way full. You can use a piping bag or a zip-top bag with the tip cut off to easily pipe the batter into the pan.
• Bake in the preheated oven for 10-12 minutes, or until the tops of the donuts spring back when lightly touched and a toothpick inserted comes out clean.
• Let the donuts cool in the pan for about 5 minutes, then transfer them to a wire rack to cool completely.

4. Prepare the Vanilla Glaze:

• In a small bowl, whisk together the powdered sugar, vanilla extract, salt, and 1 tablespoon of milk. Add more milk if you want a thinner glaze, adjusting to your preferred consistency.
• If you want to add food coloring, mix it into the glaze at this point.

5. Glaze the Donuts:

• Once the donuts have cooled, dip the tops of each donut into the glaze, coating them evenly.
• Optional: After glazing, add sprinkles or other toppings to decorate.

6. Serve:

• Allow the glaze to set for a few minutes before serving. Enjoy the donuts fresh or store them in an airtight container at room temperature for up to 2-3 days.
