Key Lime Coconut Yogurt Cake

Scott Phillips

Servings: 8 to 10

A Key lime syrup brushed over this incredibly tender pound cake makes for a delectably moist loaf, while coconut adds subtle flavor and texture without hogging the spotlight. If you can’t find fresh Key limes or bottled Key lime juice, use standard limes.


  • 5-1/2 oz. (11 Tbs.) unsalted butter, softened
  • 9 oz. (2 cups) unbleached all-purpose flour
  • 2 tsp. baking powder
  • 1 tsp. kosher salt
  • 1/4 tsp. baking soda
  • 1 cup (about 3 oz.) unsweetened shredded coconut
  • 1 Tbs. packed finely grated lime zest, preferably from Key limes
  • 1-1/4 cups granulated sugar
  • 2 large eggs
  • 3 Tbs. fresh or bottled Key lime juice
  • 1 cup plain yogurt, homemade or store-bought

  • Line a 10×5-inch metal loaf pan with aluminum foil, allowing plenty of overhang on the long sides. Use 1 Tbs. of the butter to grease the inside of the pan, paying special attention to the short (unlined) sides.
  • Position a rack in the center of the oven and heat the oven to 350°F.
  • Sift the flour, baking powder, salt, and baking soda into a large bowl. Using a fork, stir in the coconut and zest, evenly distributing any clumps.
  • In the bowl of a stand mixer fitted with the whisk attachment, or using a hand mixer, whisk the remaining 10 Tbs. butter and 1 cup of the sugar on medium speed until pale, scraping down the bowl occasionally with a silicone spatula, about 5 minutes. Reduce the speed to low and whisk in the eggs one at a time. Whisk in 1 Tbs. of the Key lime juice. (The batter may appear slightly curdled.) Add half of the flour mixture and mix briefly on low speed until incorporated. Add the yogurt and mix briefly on low speed until incorporated. Add the remaining flour mixture and mix on medium speed until the batter is smooth, about 1 minute.
  • Scrape into the prepared pan and bake until a skewer inserted in the center comes out clean, 55 to 65 minutes.
  • Meanwhile, combine the remaining 1/4 cup sugar with 1/4 cup water in a small saucepan. Bring to a boil over medium heat, stirring constantly, until the sugar dissolves. Boil one minute. Remove from the heat and add the remaining 2 Tbs. Key lime juice. Cool until needed.
  • Place the cake pan on a rack. Poke all over with a cake tester or toothpick. Brush liberally with all of the lime syrup, pausing occasionally to let it soak in. Let cool for 15 minutes. Lift out by the foil and finish cooling completely before removing from the foil and slicing.

    This cake has amazing flavor - clear lime, not too sweet, just a hint of coconut. It's very moist. I made it as a trial before berry season starts - once they're available, I'll use it as a base for blackberries and blueberries. (I usually go with pound cake rather than more biscuity cakes for shortcake.) It was amazing when warm, but on day 2 the crumb was more dense, and I found it to be a bit mushy around where the "poke" holes were, i.e., where the syrup had saturated the cake. I will likely just make a glaze for it in the future rather than soaking it in syrup.

    I bake. A lot. This is cake is sublime. It is moist, flavorful and the crumb is incredible. It is not dense like a pound cake, as it might appear, but a wonderful, fluffy, moist cake. Make it. You won't regret it.

    I followed the recipe directions exactly and have to say I was disappointed. The lime flavor was so overwhelming the first day that we couldn't eat the cake. The delicate coconut flavor was indistinguishable. The cake texture was okay but the crust was too dark and crunchy. The lime flavor mellowed the second day, but we ended up throwing the rest of the cake out even though we really wanted to like it.
