How to Make Mardi Gras King Cake Bars
-
Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking pan to ensure the bars come out easily after baking.
-
Cream together the softened unsalted butter and granulated sugar in a large mixing bowl. Mix until the mixture is light and fluffy, about 3-4 minutes.
-
Beat in the large eggs, one at a time, incorporating each before adding the next. Follow with vanilla extract and mix well for a luscious flavor.
-
Whisk together in a separate bowl: all-purpose flour, baking powder, salt, ground cinnamon, and ground nutmeg. This step ensures the dry ingredients are well combined for a consistent texture.
-
Combine the wet and dry ingredients gradually, alternating with milk. Gently mix until just combined to keep your bars tender and moist.
-
Fold in the colorful sprinkles to the batter for that festive touch. Spread the mixture evenly in the prepared pan.
-
Bake for 25 to 30 minutes or until a toothpick inserted in the center comes out clean. The edges should look slightly golden.
-
Cool the bars in the pan for 10-15 minutes. Then, transfer them to a wire rack to cool completely, which is crucial before frosting.
-
Make your frosting by beating together cream cheese and butter until creamy. Gradually mix in powdered sugar, milk, and a splash of vanilla extract until fluffy.
-
Spread the frosting generously over the cooled bars. Decorate with additional colorful sprinkles and pearl sugar, if desired, and cut them into uniform bars for serving.
Optional: Add a pinch of nutmeg to the frosting for an extra warm flavor.

Mardi Gras King Cake Bars Recipe FAQs
What type of butter should I use for the bars?
Absolutely! Unsalted butter is recommended for these bars as it provides richness and moisture. If you only have salted butter on hand, you can still use it; just reduce the added salt in the recipe to maintain balance.
How should I store the leftover bars?
You can keep Mardi Gras King Cake Bars in an airtight container at room temperature for up to 2 days, or refrigerate them for up to 5 days. Make sure to let the bars come to room temperature before serving for the best taste and texture.
Can I freeze Mardi Gras King Cake Bars?
Absolutely! For freezing, I suggest freezing the un-frosted bars in an airtight container or tightly wrapped in plastic wrap. They can be stored like this for up to 3 months. When you’re ready to enjoy, simply thaw them in the refrigerator overnight and frost them just before serving.
What should I do if my bars are too dense?
If your bars turn out dense, it might be due to overmixing the batter or not creaming the butter and sugar enough. Make sure to cream the mixture until light and fluffy, and mix the dry and wet ingredients gently—just until combined. If this has already happened, try slicing them thinly and serving with a dollop of whipped cream for extra moisture!
Are these bars suitable for those with dietary restrictions?
Yes! You can easily adapt Mardi Gras King Cake Bars for various dietary needs. For a vegan version, substitute the eggs with flax eggs (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water for each egg) and use plant-based milk. For gluten-free options, use a gluten-free flour blend to replace regular all-purpose flour. Just ensure the frosting ingredients accommodate your dietary needs too.
Can I add different flavors or mix-ins?
Very! You can certainly customize your King Cake Bars. Consider adding a layer of fruit preserves beneath the frosting for a unique twist, or experiment with different extracts like almond or orange for a delightful variety. Adding a pinch of nutmeg to the frosting can also enhance the festive flavor!
