For the cake:
  • ½ cup plain yogurt or Greek yogurt
  • 1 cup granulated sugar
  • 3 large eggs
  • 1 ½ cups all-purpose flour
  • 2 teaspoons baking powder
  • ½ teaspoon salt
  • grated lime zest from 1 medium-size lime
  • ½ cup neutral flavored oil sunflower, grapeseed, or canola oil
  • ½ cup sweetened shredded coconut
For the glaze:
  • ¼ cup fresh lime juice
  • ¾ cup of powdered sugar
  1. Preheat the oven to 350˚F (175˚C). Spray a deep (2-inch) 8-inch round cake pan with baking spray, rub inside surface of the pan with a paper towel to cover evenly with the spray. Line bottom of the pan with parchment paper. Set aside. In a large bowl, combine the yogurt, sugar, and eggs. Stir until smooth and well blended.
  2. Add the flour, baking powder, salt and zest, mixing to just combine.
  3. Add the oil and stir well. Don’t worry, at first it will seem to separate, but keep stirring till smooth.
  4. Add the coconut and stir to combine.
  5. Pour the batter into the prepared pan.
  6. Bake for 30-40 minutes or until the cake feels springy to the touch and a toothpick inserted into the center comes out clean (every oven is different, so check with the toothpick test rather than the time). Be careful not to over bake.
  7. Cool cake on a wire rack for 10 minutes; then turn it out of the pan onto the rack.
  8. Combine the lime juice and powdered sugar in a small bowl and stir until smooth. With a pastry brush, gently brush/pat the glaze all over the cake. Just keep going over the top and sides of the cake till the glaze is gone. Some of it will drip off, but most of it will soak in. Allow cake to cool completely. Sprinkle with powdered sugar if desired. The cake can also be garnished with quartered Key limes, blackberries and fresh mint as in the pictures above. Enjoy!
