Sprinkles, Sprinkles and More Sprinkles

Nothing screams birthday more than sprinkles. Use sprinkles to top any cake—be it a classic sheet cake or a towering tiered creation.

But you don’t need to stop there! You can swirl sprinkles right into your buttercream frosting. You can also press sprinkles onto the side of the cake for a truly fantastical confetti masterpiece. That’s what our Test Kitchen did for its best-ever vanilla birthday cake.

Naked Cake

A naked cake is completely bare (or nearly so) on the outside. Without the typical outer coat, the interior of the layer cake is exposed to showcase all the yummy frosting and fillings inside—like what you’ll find with this strawberry mascarpone cake or red velvet cake.

Ombre Frosting

Can’t decide between frosting colors or just want to switch up your classic frosted cake? Try an ombre effect.

Divide your favorite frosting into three batches and dye each in various shades of the same color. Pipe a wide band of each around the cake and use a wide spatula to blend and smooth out the frosting. With a few swipes, they’ll gracefully blend together.

Bundt Cake

Bundt pans are naturally decorative, so why not use them as the foundation for your celebratory cake? Top these cakes with an easy glaze and a splash of sprinkles. You can also finish them off with a hefty dose of frosting—we call that a copycat Nothing Bundt Cakes cake.

Rainbow Swirls

A simple white layer cake can transform into a showstopper birthday treat with plenty of colorful icing. Fill a piping bag with multiple colors to create streaked swirls. You can also use a small spatula to add paint-like daubs to the sides of your cake.

Cover in Ganache

Sure, frosting is delicious, but a cake covered in ganache can be over-the-top decadent. Birthday cake decorating ideas like this are perfect for the chocoholics in your life. Try it with this four-layer chocolate mousse cake or some of our other favorite chocolate cakes.

Star-Spangled

This birthday cake decorating idea looks complicated, but it’s very easy to cover your favorite layer cake in a galaxy of stars.

To make, trace star shapes (or really any shape) onto waxed paper or parchment paper. Then pipe melted white chocolate over the outline. Once dry, spritz the shapes with edible gold paint and press them onto the side of the layer cake—as we did with our princess-style cake.

12/30

Go Vertical

Birthday cake decorating ideas often start with a traditional layer cake. But what if you turned this cake on its head and made avertical layer cake? Vertical cakes are made very similarly to a cake roll. If you’ve made a cake roll or yule log cake in the past, this is a fresh technique you’ll be able to tackle.

A New Way to Upside-Down

Pineapple upside-down cakes are a perennial favorite. But you can switch up the finish by slicing the pineapple in a different way. Create a scallop pattern by slicing the rings in half and nestling cherries under each arc.

And pineapple is just the start. Be sure to check out 40+ more upside-down desserts.

Cover It in Cookies

Don’t have any special frosting tools on hand? You can still create a gorgeous themed design for your birthday cake using shaped cookies. Use storebought to save time. Simply place them on top of the cake, or adhere them to the sides with extra frosting as we did with this darling carrot layer cake.
