Preheat the oven to 350°F. Line two large, light-colored baking sheets with parchment paper.
In a medium bowl, whisk together the flour, baking powder, cornstarch, and salt and set aside.
2 1/2 cups all-purpose flour, 1/4 teaspoon baking powder, 2 Tablespoons cornstarch, 1/2 teaspoon salt
In the bowl of a stand mixer, or a large bowl if using a hand mixer, beat the butter and sugar together using the paddle attachment for 2-3 minutes. Add the egg, vanilla extract and almond extract and beat again for 1-2 minutes, scraping down the sides of the bowl as needed.
3/4 cup unsalted butter, 3/4 cup granulated sugar, 1 large egg, 1 1/2 teaspoons vanilla extract, 1/4 teaspoon almond extract
Add the dry ingredients and mix again on low until combined and the dough starts pulling away from the sides of the bowl.
Generously flour a clean work surface. Turn the dough out and divide it in half. Roll one out to 1/4-inch thick and cut out shapes with floured cookie cutters. Re-roll the scraps keep cutting until that half is used up, then repeat with the second half.
Arrange the cookies 2-3 inches apart on the prepared baking sheets. Bake the cookies in the preheated oven for 8-10 minutes, until just set and the bottom edges of the cookies turn a light golden brown. Let them cool on the baking sheets for 5 minutes then move them to a wire rack to cool completely before icing.
Once they’re cool, make the icing. Whisk together the powdered sugar, corn syrup, almond extract, and 2 Tablespoons of milk until smooth. Add up to 1 Tablespoon of milk a tiny splash at a time until it reaches the desired icing consistency. It’s ready when you lift the icing out of the bowl and the drizzles sit on the surface for a few seconds before melting back into the icing.
3 cups confectioners sugar, 1 1/2 Tablespoon light corn syrup, 3/4 teaspoon almond extract, 2-3 Tablespoons milk
Divide the icing into bowls and tint each one with gel food coloring. I leave one white and dye the rest dark red, dark green, brown, and very light pink.

Spoon the icing into plastic piping bags and snip a very small opening at the tip, or use a Wilton #1 tip. Ice the cookies and decorate with sprinkles if you like!
