Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.

In a large bowl, beat together softened butter and sugar until creamy. Add egg and vanilla extract, and mix well.

Gradually add flour to the mixture, mixing until combined.

Take small spoonfuls of dough and shape into cones resembling candy corn. Place them on the prepared baking sheet.

Bake for 12-15 minutes until edges are golden brown. Let cookies cool completely.

Melt each candy melt color separately. Dip the bottom third of each cookie in white, the middle in yellow, and the tip in orange melted candy to resemble candy corn.
