Preheat your oven to 375°F (190°C).

In a bowl, whisk together flour, baking soda, and baking powder. Set aside.

In a large bowl, cream together softened butter and sugar until smooth. Beat in the egg, vanilla extract, and almond extract until well combined.

Gradually add the dry ingredients to the butter mixture, stirring until the dough comes together.

On a lightly floured surface, roll out the dough to about 1/4 inch thick. Use cookie cutters to cut out shapes.

Place the cut-out cookies onto ungreased baking sheets, leaving space between each cookie.

Bake in the preheated oven for 8 to 10 minutes, until the edges are lightly golden. Remove from the oven and let cool on wire racks.

While cookies cool, prepare the royal icing by beating egg whites until frothy. Gradually add powdered sugar and lemon juice, mixing until smooth and glossy.

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

Once cookies are completely cooled, decorate with royal icing using piping bags or spatulas. Allow the icing to dry completely.
