# Step-by-Step Guide:

02 - Beat softened butter and granulated sugar in a large bowl until light and fluffy, about 2 minutes.
03 - Add the large egg and vanilla extract, mixing until fully combined.
04 - Gradually add the dry ingredients to the wet mixture, mixing until a smooth dough forms.
05 - Divide dough in half, flatten into discs, wrap with plastic wrap, and refrigerate for at least 30 minutes.
06 - Preheat oven to 350°F (175°C). Line two baking sheets with parchment paper.
07 - On a lightly floured surface, roll dough to 1/4-inch thickness. Cut out mitten shapes using a cookie cutter.
08 - Place cookies 1 inch apart on prepared baking sheets.
09 - Bake for 10 to 12 minutes or until edges turn just golden. Let cool on trays for 5 minutes, then transfer to wire racks to cool completely.
10 - Whisk powdered sugar, egg whites, and lemon juice on low speed until smooth and glossy. Divide and tint with desired food coloring.
11 - Use piping bags and tips to decorate cooled cookies with royal icing and optional decorations. Allow icing to set completely before serving or displaying.
