What's In This Article
King Cake is the traditional cake served on Fat Tuesday during Mardi Gras. The base is made from brioche and then frosted with powdered sugar icings.
Some don’t have any filling at all, while others are laced with cream cheese filling, raspberry or even bourbon pecan or browned butter praline. Icings are vanilla, lemon, almond or cream cheese.
Many are also topped with brightly colored sanding sugar and other festive sprinkles. People used to bake a small plastic baby in the cake. Whoever got the baby in their slice was the next person to host a party and make or buy the cake.
These cookies are the same shape and frosted just like the original. Feel free to flavor the cookie base or icing with any combination of delicious flavors you can dream up.
King Cake Cookies Ingredients
All ingredients used in this recipe can be found in most kitchens and are very simple. Let’s have a look at what’s needed to make these King Cake Cookies:
- Butter – the ingredient that makes the cookies crumbly and delicious. Use unsalted butter, softened to room temperature.
- Flour – regular all-purpose flour is used in this recipe. I do not recommend using self-rising flour because we only need a minimal amount of rising.
- Baking powder – the leavening agent in this recipe. It cannot be replaced with baking soda, as this will make the cookies spread too much.
- Sugar – I like to use brown sugar for this recipe, because it gives a more caramelized flavor. You can also use plain granulated sugar.
- Egg – one large egg is needed. Ensure it is left at room temperature for at least 1-2 hours before using.
- Vanilla extract – crucial to give the signature King Cake flavor. It can also be replaced with vanilla bean paste for a more intense flavor or almond extract or almond paste.
- Ground nutmeg – also important in achieving the right flavor. Ground cinnamon can also be used.
Royal icing is ideal for glazing these King Cake Cookies and it’s also very easy to make. We will need:
- Egg white – the base for royal icing. For food safety reasons, ensure the eggs are pasteurized. You can also use meringue powder and water instead.
- Powdered sugar – Royal icing is very smooth, so it requires very fine sugar. You cannot use granulated sugar in royal icing.
- Lemon juice – helps achieve the perfect consistency and flavor. You can also use 1-2 drops of lemon extract instead.
- Food coloring – I recommend using gel food coloring as they yield much brighter colors. The colors used are yellow, purple and green.
How to Make King Cake Cookies
- Cream the butter and sugar until pale and fluffy. Add in the egg, salt, and vanilla, then mix well to combine.
- Sift in the flour, baking soda and nutmeg. Combine the wet and dry ingredients until a dough forms, but do not overwork it. Refrigerate for 1 hour before rolling.
- Roll out the dough, then use a round cookie cutter to shape the cookies. Use a small ½ inch cutter to punch a hole in the middle of each cookie.
- Bake until golden in color, then let cool down completely on a wire rack.
Once the King Cake Cookies have cooled down completely, we can begin icing them. This is where the fun begins, and you can be as creative as you want!
- Combine all the ingredients for royal icing. Pour a few drops of lemon juice at a time until the right consistency is achieved.
- Divide the icing into 4 separate parts. Leave one part white, and color the others in yellow, green, and purple.
- In a small bowl, place white icing as a base, then add small droplets of colorful icing on top. Do not merge the colors.
- Dip the cookies face down into the royal icing, then lift and let the excess drip off. Allow to dry for at least 4-5 hours.
Optional: you can also use sprinkles, edible glitter, or luster dust for a more playful decoration of your King Cake Cookies. Apply them while the royal icing is still tacky.
Tips & Tricks
- Room temperature ingredients – the butter and egg need to be at room temperature before using in the cookie dough. This ensures the cookies will have the best texture.
- Do not add extra flour – adding too much flour can make the cookies too dense. Only add 1-2 teaspoons more if absolutely needed.
- Chill the dough – the cookie dough will be very soft and sticky before chilling, making it difficult to roll. Chilling the dough allows the dough to harden a little, making it perfect for rolling. I recommend chilling it overnight to maximise flavors.
- Do not overbake – even if the cookies seem soft freshly out of the oven, they will harden within minutes. Overbaking them can make them much too hard. Remove them once the edges are golden-brown in colour.
- Perfect royal icing marbling – when using a skewer to create a pattern, try not to go overboard. If the colours mix too much, you will get a weird looking brown. Only do 2-3 swirls at a time, so you can have clear and distinct colours.
Storage and Freezing
These King Cake Cookies are great because they have a pretty long shelf life. Once the royal icing has fully set, simply store them at room temperature in an airtight container in a dry place. They will last for up to 2 weeks without going stale.
For longer term storage, you can also freeze these Mardi Gras cookies. To freeze, wrap the cookies in aluminum foil, then place in a ziplock bag or airtight container. Freeze for up to 3 months. Thaw at room temperature for 15-20 minutes before consuming.

- Flour the worksurface, then roll out the dough using a rolling pin. If the dough is too sticky when rolling, sprinkle more flour onto it. The thickness should be ¼ inch.
- Using a 2-inch round cookie cutter, cut out 24 circles. Use a small cookie cutter or the back of a piping nozzle to cut out ½ inch holes in the middle.
- Place the cookies on the baking sheets, at least 2 inches apart. Bake for 11-12 minutes or until golden-brown on the edges.

Not sure if this is supposed to be like a shortbread cookie, but I made it last night it was delicious very much like a spiced danish cookie. However I was very upset when I read that you had a chilled towel for one to two hours which is not incorporated into your prep time in the recipe itself I had company coming over and finish these while the company was there because I needed to have it in the fridge for a few hours. Please don’t do that kind of thing incorporate the fridge time into the prepped.
We are sorry to hear that Tony. We will make the updates.
I have not made these yet, but they look fabulous – and thankfully I read all the tips.
I would like to suggest that you add “tips & tricks” to be printed along with the recipe, and other recipes that really benefit. And a video of the icing being done would be great also.
Fun, Festive and fabulous! A great treat for any Mardi Gras Celebration.
