Ingredient Breakdown
All-purpose flour – this gives the cookies structure.
Baking powder – a little bit of baking powder helps the cookies rise slightly. Do not use baking soda!
Butter – provides flavor and structure. I always recommend using unsalted butter but salted butter works if that’s all you have on hand, just be sure to omit the 1/2 teaspoon of salt later on. Do not use cold or melted butter.
Granulated sugar – sweetens and softens cookies. Do not substitute it with brown sugar.
Eggs – helps bind the ingredients.
Vanilla extract and salt – enhances flavor. Always use pure vanilla extract instead of imitation for best flavor.
How To Make Halloween Ghost Sandwich Cookies
1. Make the sugar cookie dough: in a small bowl whisk all-purpose flour, baking powder and salt. Set aside.
2. Use a stand mixer fitted with the paddle attachment to cream softened butter and granulated sugar until light and fluffy.
3. Add eggs one at a time and vanilla until just combined. Scrape the sides of the bowl.
4. Add the dry ingredients all at once and mix on low speed until just combined. The dough will be soft but not sticky.
5. Divide dough in half then shape into flat discs. Wrap each tightly with plastic wrap then refrigerate for at least 2 hours or up to 3 days.
6. On a floured surface, roll out one disc of dough to about 1/8 inch thick. Cut out ghosts and place on a baking sheet then freeze for at least 5 minutes.
7. Bake cookies at 350°F for 9 minutes then allow to cool completely. The cookies should be pale but not wet looking when they come out of the oven. Repeat with the second disc of dough. You can reroll the dough scraps up to 2 more times.
8. Make the black cocoa buttercream: cream butter until light and fluffy on a stand mixer fitted with the paddle attachment or with a hand mixer.
9. Add the black cocoa powder and mix on low then add the confectioners’ sugar and mix on low until combined. Scrape the bowl as needed.
10. Add vanilla extract and heavy cream or milk then beat until fluffy. Add salt to taste. The buttercream will darken as it sits so don’t panic if it isn’t super black yet! I recommend making it the day before decorating to give it plenty of time to darken.
11. Assemble the ghost sandwich cookies: Melt the white chocolate chips in the microwave or over a double boiler. If the chocolate is too thick add a TINY bit of vegetable oil (like 1/4 tsp at a time).
12. Dip half of the ghosts in the melted white chocolate. Use a small offset spatula to smooth them out then set aside so the chocolate can harden. You can skip this step if you don’t like white chocolate, the cookies will still be delicious!
13. Pipe or spread a layer of black cocoa buttercream onto the remaining half of cookies then top with the white chocolate covered cookies.
14. Use a piping bag or a zip-top bag filled with black cocoa buttercream to pipe faces onto each of the ghost sandwich cookies. Store Halloween Ghost Sandwich Cookies in an airtight container for up to 5 days at room temperature or up to a week in the fridge.
Pro Tips For Ghost Sandwich Cookies
- Weigh your ingredients using a kitchen scale! Measuring ingredients by volume is not accurate.
- Don’t over mix the dough! Only mix until the dry ingredients are just combined. Over mixing = more gluten development which means tough cookies. We don’t want any tough cookies here!
- Bake one tray at a time on the middle oven rack. This ensures that there is even heat circulation.
- Don’t over bake them! They should still be pale when they come out of the oven because they will continue to bake as they cool on the baking sheet.
- Make the black cocoa buttercream in advance. It darkens as it sits so don’t panic if it’s not pitch black immediately after making it. I recommend making it the day before decorating the cookies.
- Keep the sugar cookie dough cold! If you put warm cookies in the oven they will spread so I recommend freezing the cookies for a few minutes before baking them.
Frequently Asked Questions
What Is Black Cocoa Powder?
Black cocoa powder is cocoa powder that has been super Dutch processed which just means that it has been treated with an alkaline solution to reduce its acidity. This results in a mellower flavor and darker color. It’s actually the ingredient in Oreos that give them their unique flavor and color!
Thanks to the magic of black cocoa powder, this buttercream uses zero food coloring but if by some chance your buttercream doesn’t turn out dark enough then I recommend using a few drops of black gel food coloring. Gel food coloring is the best because it yields a deeper color without using a ton of dye and throwing off the consistency and taste of the buttercream the way liquid food coloring does.
My go to black cocoa powder is made by Wincrest but any brand should work fine!
Can You Make Sugar Cookie Dough In Advance?
Yes! Once you make this sugar cookie dough you can either refrigerate it for up to 3 days wrapped tightly in plastic wrap or freeze it for up to 3 months wrapped tightly in plastic wrap and placed in a zip-top bag.
Why do you have to chill sugar cookie dough?
You need to chill sugar cookie dough in order to make the dough easy to work with and to prevent your cookies from spreading too much. If you’re dough is warm then it will become sticky and difficult to handle. I recommend chilling your dough for at least 2 hours before rolling it out and chilling your cookies in the fridge or freezer right before baking them.
How Do Sugar Cookies Keep Their Shape?
Sugar cookies have a high ratio of flour to fat which makes the dough sturdy enough to roll out and cut into shapes. Additionally, the dough is always kept cold which aids in cookies maintaining their shape. My favorite trick to prevent sugar cookies from spreading is to freeze your cookies for 5 minutes before baking them!
What’s the difference between sugar cookies And Shortbread?
Unlike sugar cookies, shortbread is made without eggs or any leavening agents. Shortbread also has a more crumbly texture as a result of the dough’s high fat content. If you’re looking for shortbread recipes try my Mini Chocolate Chip Shortbread Bars or Shortbread Thumbprint Cookies.
