Piped Rainbow Shortbread Cookies (Print Version)

# Ingredients:

→ For the Cookies

01 - 2¼ cups all-purpose flour
02 - ¾ cup sugar
03 - ¼ tsp salt
04 - 1 cup unsalted butter, cut into pieces
05 - Gel food coloring (4 colors of your choice)

→ For Decoration

06 - 1 cup white melting wafers
07 - Rainbow nonpareils (for topping)

# Instructions:

01 - Preheat oven to 325°F (160°C). Line 2 baking sheets with parchment paper.
02 - In a food processor, pulse the flour, sugar, and salt together to combine thoroughly.
03 - Add half of the butter pieces to the food processor and pulse a few times. Then add the remaining butter and continue pulsing in short bursts until the dough comes together.
04 - Divide the dough into 4 equal portions and place each in a separate bowl. Add different gel food coloring to each portion and mix well until the color is evenly distributed throughout the dough.
05 - Lay out a sheet of plastic wrap on your work surface. Place each colored dough in strips side by side, arranging them from lightest to darkest color. Roll them together to form a cylinder shape, then cut one end to create a clean edge.
06 - Place the dough cylinder into a piping bag fitted with a large star tip.
07 - Pipe cookies onto the prepared baking sheets, leaving space between each cookie to allow for slight spreading during baking.
08 - Bake in the preheated oven for 25 minutes, rotating the pans halfway through the baking time. The cookies should be set but not browned.
09 - Allow the cookies to cool completely on a wire rack before decorating.
10 - Place the white melting wafers in a microwave-safe bowl. Microwave in 10-second intervals, stirring between each interval, until completely melted and smooth.
11 - Dip the piped edge of each cookie into the melted white chocolate, then immediately sprinkle with rainbow nonpareils before the chocolate sets.
12 - Place the decorated cookies on parchment paper and allow the chocolate to completely set before serving or storing.

# Notes:

01 - Store in an airtight container at room temperature for up to 1 week
02 - For best color results, use gel food coloring rather than liquid
03 - If dough becomes too soft to pipe, refrigerate for 15-20 minutes
04 - Perfect for birthday parties, baby showers, or any colorful celebration
