In a large mixing bowl, cream together the unsalted butter and granulated sugar until light and fluffy. Add the egg and vanilla extract, mixing until well combined.

Make the Cookie Dough

In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until a dough forms.

Combine Dry Ingredients

Divide the dough into equal portions and roll them into balls. Flatten slightly and place them on a baking sheet lined with parchment paper.

Shape the Cookies

Preheat the oven to 350°F (175°C). Bake the cookies for 10-12 minutes or until the edges are lightly golden. Remove from the oven and let them cool completely on a wire rack.

Bake the Cookies

In a large bowl, combine the powdered sugar and egg white powder. Gradually add water while mixing on low speed until the icing reaches a thick but spreadable consistency.

Mix the Royal Icing

If desired, divide the icing into separate bowls and add food coloring to each to create different colors.

Color the Icing

Using a piping bag or a small spatula, spread or pipe the royal icing onto the cooled cookies. Allow the icing to set for about 15 minutes.

Ice the Cookies

While the icing is still wet, sprinkle with sprinkles, chocolate chips, chopped nuts, or edible glitter as desired.

Add Decorations

Let the decorated cookies sit at room temperature for at least 1 hour to allow the icing to harden completely.
