Creating these magical Witch Hat Cookies is a delightful experience. Follow these steps to make your own:

1. Preheat the Oven: Set your oven to 350°F (175°C) and line a baking sheet with parchment paper.
2. Mix Dry Ingredients: In a medium bowl, whisk together the flour, cocoa powder, baking powder, and salt.
3. Cream Butter and Sugar: In a large bowl, beat the softened butter and granulated sugar until fluffy and light.
4. Add Egg and Vanilla: Mix in the egg and vanilla extract until well combined.
5. Combine Mixtures: Gradually combine the dry ingredients with the wet ingredients, stirring until a dough forms.
6. Form Cookies: Scoop tablespoon-sized portions of dough onto the prepared baking sheet, leaving space between each scoop.
7. Bake the Cookies: Bake for 10-12 minutes, until the cookies are firm. Allow them to cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely.
8. Frost and Assemble: Once cookies have cooled, pipe a generous amount of chocolate frosting on top of each cookie.
9. Add the Hats: Place the chocolate wafer cookie on top of the frosting, followed by a piece of candy corn as the point of the witch’s hat.
10. Allow to Set: Let the frosting set before serving to keep everything in place.

By following these steps, you’ll create an enchanting batch of Witch Hat Cookies that are sure to impress and delight everyone at the gathering.
