01 - Preheat oven to 375°F. Lightly grease a standard 12-cavity donut pan with cooking spray or butter.
02 - In a medium bowl, whisk together flour, sugar, baking powder, cinnamon, nutmeg, and salt until well blended.
03 - In a separate bowl, whisk eggs, milk, melted butter, vanilla extract, and almond extract if using, until smooth and fully incorporated.
04 - Pour wet ingredients into dry ingredients. Stir gently with a spatula or wooden spoon until just combined. The batter should remain slightly thick. Avoid overmixing to prevent tough donuts.
05 - For filled donuts, beat softened cream cheese, powdered sugar, and lemon zest in a small bowl until smooth and creamy.
06 - If making filled donuts, fill each cavity halfway with batter. Add 1 teaspoon of cream cheese mixture to the center, then cover with remaining batter. For unfilled donuts, fill each cavity about 3/4 full.
07 - Bake for 10 to 12 minutes until donuts are golden brown and spring back when lightly touched. A toothpick inserted should come out clean.
08 - Let donuts cool in the pan for 5 minutes, then carefully transfer to a wire rack to cool completely before icing.
09 - Whisk powdered sugar, milk, and vanilla extract in a small bowl until smooth. The glaze should be thick enough to coat but thin enough to drizzle.
10 - Dip the top of each cooled donut into the icing or drizzle over the surface. Immediately sprinkle with purple, green, and gold sanding sugar or sprinkles before the icing sets.
