The Haunted Bakeshop: The Essential Ingredients & Tools

This iconic party treat uses a handful of high-quality ingredients and a few key techniques to create its signature festive look.

  • The Spooky Chocolate Cookie:
    • Dutch-Process Cocoa Powder: This is the secret to the cookie’s deep, dark color and its smooth, rich, and less acidic chocolate flavor. It creates the perfect, dark background for your white icing “bones” to pop.
    • The Spices: A generous amount of warm, fragrant ground cinnamon is the key to that classic, cozy, and slightly spicy flavor that perfectly complements the rich chocolate.
    • Chilling the Dough: This is the single most important, non-negotiable secret to a cut-out cookie that holds its sharp, detailed shape in the oven. Chilling the dough solidifies the butter, which is the key that prevents the cookies from spreading into sad, puffy blobs.
  • The Royal Icing “Bones”:
    • Meringue Powder: This is the essential, modern secret to a safe, stable, and easy-to-use royal icing. Meringue powder (which is made from dried egg whites) is a fantastic substitute for raw egg whites, and it creates an icing that whips up beautifully and dries to a hard, perfect finish. You can find it in the baking aisle of most major grocery stores or at a craft store.
  • The Key Equipment: A classic gingerbread man cookie cutter, a few piping bags, and a small, round piping tip are all you’ll need to bring your skeletons to life.

The Dark Arts of Baking: The Secret to Perfect ‘No-Spread’ Cookies

The number one, non-negotiable secret to a perfect cut-out cookie that doesn’t spread is multiple stages of chilling.

  1. Chill the Dough Discs: The initial, one-hour chill after mixing the dough is crucial for firming up the butter and hydrating the flour.
  2. Chill the Rolled Sheets: This recipe’s brilliant second chilling step is a professional secret! By chilling the thinly rolled-out sheets of dough until they are very firm, you are ensuring that your cut-out shapes will be incredibly sharp and easy to handle.
  3. The Final Chill: A final, quick 15-minute chill of the cut-out cookies on the baking sheet before they go into the oven is the ultimate insurance policy against spreading. This is the foolproof, professional secret that guarantees your cookies will hold their beautiful, sharp shape.

Step-by-Step to the Best Chocolate Skeleton Cookies

This fun and festive project is a joy to prepare.

Step 1: In a medium bowl, whisk together the 1 3/4 cups of all-purpose flour, the 3/4 cup of Dutch-process cocoa powder, the 1 tablespoon of ground cinnamon, the 3/4 teaspoon of baking soda, the 1/4 teaspoon of baking powder, and the 1/2 teaspoon of salt.

Step 2: In the bowl of a stand mixer, beat the 2 sticks of room temperature butter, the 1 1/4 cups of granulated sugar, and the 1/2 cup of packed dark brown sugar together on a medium-high speed for about 5 minutes, until the mixture is very light and fluffy.

Step 3: Beat in the 1 large egg and the 1 teaspoon of pure vanilla extract until creamy.

Step 4: Turn the mixer to low and gradually add the flour mixture, mixing until a thick dough forms.

Step 5: Divide the dough in half, pat each half into a disc, and wrap them in plastic wrap. Refrigerate the dough until it is firm, for at least 1 hour.

Part 2: Cut, Bake, and Cool Your Spooky Skeletons

Step 1: Once the dough is chilled, roll out each disc between two sheets of parchment paper until it is about 1/4-inch thick. Place these rolled sheets of dough in the refrigerator until they are very firm, for at least another 2 hours. Step 2: First, preheat your oven to 350°F (175°C). Line two large baking sheets with parchment paper. Step 3: Use your gingerbread man cookie cutter to cut out your spooky shapes from the cold dough and arrange them about 2 inches apart on your prepared baking sheets. Refrigerate the cut-out cookies on the pans for 15 minutes before baking. Step 4: Bake for 15 minutes, until the cookies are set but still soft. Let the cookies cool completely on a wire rack.

Part 3: The Art of Royal Icing and Decoration

Step 1: To make the royal icing, beat the 1 cup of confectioners’ sugar, the 1 tablespoon of meringue powder, and 1 to 2 tablespoons of water in a bowl with a mixer on a high speed until the icing is smooth and thick. Step 2: Transfer your icing to a piping bag that has been fitted with a very small, round tip. Step 3 (The Fun Part!): Decorate your cooled cookies! Pipe a simple, round “skull” for the head, and then have fun piping on all the “bones” for the rib cage, the arms, and the legs. Let the icing set completely, which will take about 30 minutes.

Ingredients

  • For the cookies:
  • 1 3/4 cups all-purpose flour
  • 3/4 cup unsweetened Dutch-process cocoa powder
  • 1 tablespoon ground cinnamon
  • 3/4 teaspoon baking soda
  • 1/4 teaspoon baking powder
  • 1/2 teaspoon salt
  • 2 sticks (1 cup) unsalted butter, at room temperature
  • 1 1/4 cups granulated sugar
  • 1/2 cup packed dark brown sugar
  • 1 large egg
  • 1 teaspoon pure vanilla extract
  • For the icing:
  • 1 cup confectioners’ sugar
  • 1 tablespoon meringue powder
  • 1 to 2 tablespoons water

Instructions

  1. Make the Cookie Dough: In a medium bowl, whisk together the flour, cocoa powder, cinnamon, baking soda, baking powder, and salt.
  2. In a large bowl with a mixer on medium-high speed, beat the butter, granulated sugar, and brown sugar until light and fluffy, about 5 minutes. Beat in the egg and vanilla until creamy.
  3. Reduce the mixer speed to low. Gradually add the flour mixture and beat until combined.
  4. Divide the dough in half; pat each piece into a disk and wrap in plastic wrap. Refrigerate until firm, for at least 1 hour.
  5. Roll out each dough disk between 2 sheets of parchment paper until 1/4 inch thick. Refrigerate the rolled dough until very firm, for about 2 hours.
  6. Bake the Cookies: Preheat the oven to 350°F. Line 2 baking sheets with parchment paper. Cut the dough into shapes using a 4 1/2-inch gingerbread man cookie cutter and arrange them 2 inches apart on the prepared pans. Reroll the scraps and cut out more cookies.
  7. Refrigerate the cut-out cookies on the pans until firm, about 15 minutes.
  8. Bake, switching the pans halfway through, for 15 minutes. Let the cookies cool on the pans for 10 minutes, then transfer them to wire racks to cool completely.
  9. Make the Icing and Decorate: Beat the confectioners’ sugar, meringue powder, and water in a bowl with a mixer on high speed until smooth and thick. Transfer the icing to a resealable plastic bag and snip off a tiny corner.
  10. Pipe skulls and bones onto the cooled cookies. To ‘flood’ the skull, thin some of the icing with a little water and fill in the outline, using a toothpick to spread it. Let the icing set for at least 30 minutes.

Notes

  • This is a classic cut-out cookie recipe that requires multiple, lengthy chilling steps. Chilling the dough is a crucial step to ensure the cookies hold their shape and don’t spread during baking.
  • The icing is a simple royal icing that uses meringue powder, which allows it to dry hard and is a safe alternative to raw egg whites.
  • The two-step decorating process of outlining and then ‘flooding’ with a thinned icing is a standard technique for creating detailed cookie designs.

Storage and Make-Ahead Tips

These Halloween Skeleton Cookies are the ultimate make-ahead party treat!

  • Make-Ahead: The unbaked cookie dough can be made up to 3 days in advance and stored, well-wrapped, in the refrigerator. The baked and un-decorated cookies will also stay fresh in an airtight container for up to a week.
  • Storage: Store the finished, decorated cookies in a single layer in an airtight container at room temperature for up to 2 weeks.

Frequently Asked Questions (FAQs)

Q1: What is the absolute, number one secret to cut-out cookies that don’t spread in the oven?

The secret is to use very cold dough. This recipe uses a brilliant, three-stage chilling process: first, you chill the dough discs; second, you chill the rolled-out sheets of dough; and third, you chill the final, cut-out cookies on the baking sheet before they go into the oven. This is the foolproof, professional secret that guarantees your cookies will hold their beautiful, sharp shape.

Q2: What is meringue powder, and do I really need it for royal icing?

Meringue powder is a fine, white powder made from dried egg whites. It is the modern, secret weapon for a perfect royal icing because it is completely shelf-stable, easy to use, and eliminates any food safety concerns associated with using raw egg whites. It is the key to an icing that will whip up to a beautiful, stiff consistency and will dry to a hard, matte finish.

Q3: Can I make these Halloween cookies ahead of time for a party?

Yes, absolutely! These are the perfect make-ahead cookie. You can bake the cookies one week, and then decorate them over the next few days. The finished, fully dried cookies will stay fresh and beautiful for up to two weeks.

Q4: How long does royal icing really take to dry?

Patience is key! A simple, piped outline icing, like the one on these cookies, will be dry to the touch in about 30 minutes to an hour. If you were to use a thinner, “flood” icing, it would need at least 6 to 8 hours to dry completely hard.

Q5: Can I freeze these cookies?

Yes! You can freeze the unbaked dough for up to 3 months. You can also freeze the baked, un-decorated cookies. For the best result, it is not recommended to freeze the finished, decorated cookies, as the delicate royal icing can sometimes become brittle or the colors can bleed as they thaw.
