Everyone has a favorite cake flavor that they pick every year for their birthday. But there are some unusual cake flavors that, while they’re not at the top of anyone’s list, might be worth trying out.

Beetroot Cake

Shredded beets are the star of beetroot cake, which also often features chocolate. Fans say beet cake is very moist and tastes delicious. It also has a lush red color.

Tahini Cake

Tahini is a smooth, creamy and very flavorful paste made from sesame seeds that’s common in North African and Middle Eastern cooking—it’s a key ingredient in hummus, for example. Turns out tahini contributes to a moist and delicious cake, too.

Coke Cake

Search online and you’ll find, surprisingly enough, lots of recipes for Coke cake. It’s a Southern thing, apparently, that uses cola to create a moist, bouncy—but very sweet—confection.

Olive Oil Cake

This moist cake is a gift from the Mediterranean, where olive oil reigns supreme. Lemon gives many olive oil cake recipes another boost of delicious flavor, while others call for orange juice or zest.

Tomato Soup Cake

This red beauty uses a full can of condensed tomato soup, plus lots of spices to create a warm, comforting dessert. It’s a delight from the 1950s that’s been updated a bit. It’s often topped with a cream cheese frosting.

Cardamom Cake

While we might think of cardamom as the rich spice that flavors many Indian dishes, cardamom cake is a delight given to us by Sweden, where it’s often enjoyed in the afternoon alongside tea or coffee. Ground cardamom adds a floral, citrusy flavor.

Parsley Cake

One parsley cake recipe calls for mint and a whopping 4 cups of parsley leaves! Aficionados swear by this very, very green cake, enjoying it at every opportunity. Others, however, might want to break it out just for St. Patrick’s Day.
