Cream the butter, cream cheese, and sugar together until light and fluffy, about 2 to 3 minutes. Beat in the egg and vanilla until fully combined, scraping the bowl once. Stir in the flour, baking powder, and salt until a soft dough forms.

Split the dough into four or five portions. Knead a different gel food coloring into each portion until evenly colored. Wear gloves to avoid stained hands. Wrap each colored dough tightly in plastic wrap.

Refrigerate the wrapped dough portions for 30 minutes until firm. Cold dough rolls cleanly and holds its shape during twisting and coiling.

On a lightly floured surface, roll each color into a rope about 1/2 inch thick and 6 inches long. Press the ropes together gently, twist them lightly, then coil into a loose poop shape on a parchment-lined baking sheet. Press sprinkles into the tops.

Bake at 350°F (175°C) for 10 to 12 minutes until the tops look dry and the bottoms are lightly golden. Cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely. Add edible glitter after cooling if desired.
