Place the semi-sweet morsels in a microwave safe bowl. Microwave on 50% power for 40 seconds, then stir, then microwave on 50% for 20 seconds at a time, stirring in between, until the morsels are completely melted.
12 oz semi-sweet morsels
Place a sheet of wax paper on a cookie sheet or other flat tray. Dip each round cookie or cracker in the chocolate, scrape off the excess, and place on the wax paper. Refrigerate until the chocolate hardens.
24 round flat cookies or buttery crackers
Add ½ cup powdered sugar and ½ tablespoon water in each of 3 small bowls. Add a few drops of food coloring in each to create the orange, green, and purple colors. Mix well until the icing is stiff. Add more food coloring, a drop or two at a time, until the colors are vibrant enough for you. If the icing is too stiff, add a little water. If it is too runny, add a little more sugar.
1.5 cup powdered sugar, 1.5 tbsp water, Orange, green, and purple food coloring
Remove the chocolate covered rounds from the refrigerator. Drop a dollop of icing (about ¼ teaspoon) to the center of each, then press down with a chocolate kiss so that the excess icing forms a ring around the bottom.
24 chocolate kisses
Allow the icing to set for 15-20 minutes before serving.
Notes
Prep Tips:
Have the wax paper ready before you start dipping the cookies so you can work quickly once the chocolate is melted.
Don't worry about getting the chocolate coating perfectly smooth—the icing and chocolate kiss will cover the center of each cookie anyway.
When making the colored icing, add the water gradually. It's much easier to thin a stiff icing than to fix one that's too runny.
If you're making all three icing colors at once, use separate small bowls so the colors stay clean and vibrant.
Unwrap all of the chocolate kisses before you start assembling the hats. This makes the final decorating step go much faster.
Give the icing enough time to set before moving or stacking the cookies so the chocolate kisses stay securely in place.
Variations:
Use melted white chocolate instead of the powdered sugar icing, or try colored candy melts for an especially easy decorating option.
Choose different varieties of chocolate kisses, such as peanut butter or caramel-filled, to add a surprise flavor.
Use thin chocolate mint cookies instead of dipping the crackers in chocolate for a shortcut.
Drizzle the finished witch hats with melted peanut butter, caramel, or white chocolate and add festive sprinkles.
Replace the chocolate kisses with chocolate-coated marshmallows to turn the witch hats into cute little top hats.
Serving Suggestions:
Arrange the witch hats on a platter for Halloween parties, classroom treats, or fall gatherings.
Alternate the orange, green, and purple hats for a colorful display.
Package a few in individual treat bags for fun Halloween favors.
Storage:
Store the finished witch hats in an airtight container at room temperature for up to 5 days.
Keep them in a cool, dry place so the chocolate doesn't soften or develop condensation.
Refrigeration is fine if your kitchen is warm, but allow the treats to sit at room temperature briefly before serving for the best texture.
