For the Donuts:

1. 1. Preheat your oven to 350°F (175°C). Grease a donut pan with nonstick cooking spray or butter.
2. 2. In a large bowl, whisk together flour, sugar, baking powder, and salt until well combined.
3. 3. In another bowl, mix milk, eggs, melted butter, and vanilla extract until smooth.
4. 4. Pour the wet ingredients into the dry ingredients and gently mix until just combined—do not overmix.
5. 5. Spoon or pipe the batter into each cavity of your prepared donut pan about two-thirds full.
6. 6. Bake for about 10-12 minutes or until golden brown. Test doneness with a toothpick; it should come out clean.
7. 7. Let cool in the pan for about five minutes before transferring to wire racks.

For the Glaze:

1. 1. In a bowl, combine powdered sugar and milk to reach your desired glaze consistency.
2. 2. Divide the glaze into separate bowls if using multiple colors and add food coloring as desired.
3. 3. Dip each cooled donut into the glaze and sprinkle with Halloween-themed toppings while still wet.
