Part 1: Gathering the Supplies for the Harry Potter Gender Reveal Cookies

To create these buttercream sugar cookies for your gender reveal party, you will want to gather:

  • 2 Icing bags
  • A Wilton tip #2 and a Wilton tip #4
  • Sorting Hat cookie cutter
  • Brown, black, AND pink or blue Wilton gel color
  • 9″ Angled flat spatula and/or a butter knife
  • Pizza cutter or sharp knife
  • No chill, no spread sugar cookie dough – see recipe below
  • Crusting buttercream – see recipe and notes below

Part 2: Baking the Cookies and Setting up Your Icing Bags

How to Make Gender Reveal Cookies

Remember to check out the video above to see the full process. Here are all of the steps below.

  1. Using the recipe below, follow the instructions through step 5. Once you have your ball of dough formed, pull out about 1/4 of a cup of the dough and set it aside.
  2. On a floured surface, roll out the larger ball of dough to about 1/4″ thick and cut out your Sorting Hat cookies. Place these cookies onto a lined baking sheet. I like to use this silicone mat. Don’t bake them yet!
  3. Place the reserved 1/4 of a cup of dough back into your stand mixer. Use a fork to pull out some of the blue or pink gel food coloring and wipe it onto the dough. Mix up your colored dough in the mixer.
  4. On a floured surface, roll out the dough to about an 1/8th of an inch thick. Using the cookie cutter as a guide, cut strips of the colored dough such that they will fit onto the cookie without getting near the edges. We don’t want any sneak peeks before the big reveal!
  5. Place the strips onto the prepared sorting hat cookies. If they don’t want to stick, you can slightly wet the colored dough with water or just place the non floured side down onto the Sorting Hats. Then, press the colored dough further into the Sorting Hat cookies using a spoon or your fingers.
  6. Bake for about 9 minutes or until the edges are slightly golden. Since you pushed the colored dough into the cookies, you shouldn’t need to adjust your cooking time by more than a minute or so.

  • Stand Mixer with Paddle Attachment
  • Measuring Bowls & Spoons


  • 1 cup cold salted butter cut into cubes
  • 1 cup granulated white sugar
  • 1 egg
  • 3 cups all purpose flour
  • 2 tsp baking powder
  • 1.5 tsp vanilla extract


  • Preheat your oven to 350 degrees.
  • In a large bowl, mix your flour and baking powder together. When measuring the flour, make sure to scoop up the flour with a spoon and add it to your measuring cup, one spoonful at a time. This helps obtain the correct amount of flour without needing to weigh it. Once you have a cup, level it out by running a knife across the top of the measuring cup. Then, add it to the large mixing bowl and repeat for the remaining flour. Set the mixture of flour and baking powder aside for a minute.
  • In your electric mixer, combine the sugar and butter using the paddle attachment until they are creamed together.
  • Add in your egg and vanilla extract and mix to combine.
  • Slowly add in one cup (or whatever your mixer can handle) at a time of the flour mixture to the wet ingredients. The mixture should be slightly sticky but still form a nice ball.
  • On a floured surface, roll out the dough to about a 1/4 of an inch thick & cut out your cookies. A great tip is to flour your rolling pin and any cookie cutters you may be using. Transfer the cut out cookies to a baking sheet lined with a  silicone mat using a large flat spatula.
  • Bake for about 10 minutes and let cool on the baking sheet. The dough will be done when the center of the dough doesn’t look wet and the edges are golden.


Place in an air tight container in the freezer if you aren't decorating these cookies within 24 hours. Allow the cookies to come back to room temperature before frosting.

How to Set up the Buttercream Icing Bags

  1. Make your buttercream icing using the recipe below and separate it into two bowls. You will only need about 1 cup for the black buttercream so your amounts in each bowl will be different. Mix in your black and brown gel colors. To create a deep shade, mix in just enough to get about 3/4 of the way to your desired shade. Then, place a piece of plastic wrap over the frosting and allow it to sit on the counter for a few hours to deepen. If you don’t have the time to do this, then just add more gel color. Remember that the color will still deepen as it sets.
  2. Set up your icing bags as follows: Place the black frosting into an icing bag with the Wilton tip #2 in it. Place the brown frosting into an icing bag with the Wilton tip #4 in it.

All American Crusting Buttercream Frosting Recipe

I recommend using a crusting buttercream when decorating buttercream sugar cookies. This allows the buttercream to form an outside crust, giving them a bit more protection from getting accidentally squished. This is essential if you plan to transport these cookies from your house to another location or if you want to stack or seal them.

  • Stand Mixer with Paddle Attachment
  • Measuring Spoons & Bowls


  • 1 cup room temperature unsalted butter
  • 1 cup vegetable shortening such as Crisco
  • 2 lbs. plus 1 cup powdered sugar
  • 2 tsp. clear vanilla extract I use artificial
  • 2-4 tbsp. give or take room temperature whole milk


  • In your electric mixer, use the paddle attachment to mix the butter and vegetable shortening together. 
  • Slowly mix in the powdered sugar, only adding as much as your electric mixer can handle at a time.
  • Mix in the vanilla extract and 2 tbsp. of milk. If the mixture is too stiff, add more milk. I prefer a consistency of smooth peanut butter for cookies that have a lot of line work and a slightly stiffer consistency for piping flowers.


This recipe will store nicely in the fridge for a few weeks in an airtight container. You can also leave your decorated cookies at room temperature for several days, as the frosting will be shelf-stable due to the mixture of sugar and fat.

Part 3: Decorating the Sorting Hat Gender Reveal Cookies

  1. The first step is to use the black frosting with tip #2 to cover part of the cookie area. This will become the Sorting Hat’s eyes and mouth.
  2. Using the angled flat spatula or a butter knife, smooth out the frosting so that it is thin and covering up the whole to-be-eyes-and-mouth area.
  3. Use the brown frosting with tip #4 to outline the edge of the cookie. Then, outline the eyes and the mouth. When creating outlines, remember that the shape on the inside of the outline is what matters. In other words, make sure the eyes and mouth are as large as you want them from the inside view. how to make harry potter sorting hat cookies
  4. Fill in the Sorting Hat using the brown icing. I decided to keep the classic buttercream lines since the Sorting Hat is quite wrinkly! how to decorate harry potter gender reveal cookies sorting hat sugar cookies

The buttercream decorating is so easy for these Harry Potter gender reveal cookies! Now all that’s left to do is allow these cookies to crust on the counter overnight before the day of the big reveal.

Storing & Freezing Decorated Sugar Cookies

Buttercream sugar cookies can be decorated ahead of time. Store these in the freezer for up to two weeks in an airtight container. Something like this works great because it’s shallow. Just make sure not to stack the cookies in the freezer, they should all be in a single row.
