This fluffy, vibrant cake boasts layers of purple, green, and gold icing, capturing the spirit of celebration with every bite. The batter combines staple ingredients like butter, sugar, eggs, and vanilla, baked to golden perfection. The smooth, tricolor icing is whipped with powdered sugar and milk, then tinted to create striking stripes or swirls on the cake’s surface. Ideal for festive occasions, this cake offers a rich texture, bright colors, and a sweet, creamy finish.

Preparation involves mixing a tender batter, baking in round pans, and cooling before assembling the icing layers. The tricolor stripes lend a playful, eye-catching look that pairs beautifully with sweet wines and sparkling beverages. This dessert brings the joy of Mardi Gras with its vibrant appearance and luscious flavors.

The first time I made this cake, my kitchen counter looked like a rainbow exploded. I had purple frosting on my elbow, green smudges on my apron, and gold sprinkles somehow found their way into my hair. My roommate walked in, took one look at me, and asked if I'd started a circus. That cake became the centerpiece of our impromptu Fat Tuesday party that year.

Last year I brought this to a potluck and watched people's faces light up when I sliced into it. Something about those iconic Mardi Gras colors makes people immediately happy. My friend's daughter kept pointing at each color and asking if she could have the purple slice only.

My niece helped me decorate this cake last year and she took her color分配 very seriously. Purple was her favorite so she made sure that stripe was the thickest. The cake ended up looking slightly lopsided but honestly that made it even better.

Making It Ahead

I learned the hard way that fresh cake is easier to frost than completely cooled cake. Bake the layers a day ahead wrap them tightly in plastic and let them sit at room temperature. The slight crusting on the outside actually helps the frosting adhere better.

Getting Those Colors Right

Start with less gel coloring than you think you need. You can always add more but you cant take it back. I keep a small bowl of plain frosting on the side to dilute any color that gets too intense too fast.

Frosting Like A Pro

Use an offset spatula and keep a glass of warm water nearby to dip it in. The warm metal helps smooth the frosting and gives you that professional finish. Work quickly once the frosting is on the cake because it starts to form a crust.

  • Apply a thin crumb coat first then refrigerate 15 minutes
  • Start with the lightest color first so you dont have to clean your spatula as often
  • Spin the cake stand as you work for smoother stripes
