Ingredients

  • 1 & 1/4 cup flour 175 grams
  • 2/3 cup sugar 140 grams
  • 3/4 tsp baking soda
  • 1/2 tsp kosher salt
  • 2/3 cup avocado oil 125 grams
  • 4 ounces coconut flavored greek yogurt or skyr
  • 2 large eggs
  • 3 tbsp lime juice
  • Zest from 2 limes
  • 8 ounces lime flavored greek yogurt or skyr, or plain
  • 1/2 cup coconut flakes for topping
  • 2 tbsp flax meal for topping
  • optional extra lime zest for topping

Instructions

  • Preheat the oven to 350F.
  • In a large bowl, whisk together the flour, sugar, baking soda, and salt.
  • Add the yogurt, oil and eggs directly to the large bowl. Whisk vigorously to combine. When it is smooth, switch to a spatula.
  • Add in the 3 tbsp of lime juice and the zest from one lime. Use a spatula to swirl this into the batter until evenly mixed.
  • Line the bottom of a 9" springform pan with parchment paper. Lightly oil the sides of the pan with a spray oil or a few drops of avocado oil. Pour in the batter.
  • Bake at 350F for 20-22 minutes or until the cake is golden brown and you can insert a toothpick and it comes out clean.
  • Let the cake cool completely before releasing it from the springform pan.
  • While the cake is cooling, mix together the lime yogurt or skyr with the zest from one lime. If you are using plain yogurt, add in the juice from the lime as well. Stir to combine.
  • Use a serrated knife to cut any doming off the cake, then flip it over and remove the parchment paper. Ice the cake with the lime yogurt, and top with coconut, flax seed, and extra lime zest. Slice & serve!
