These Coconut Lemon Lime Squares are an upgraded lemon bar with a coconut cake crust and a lemon-lime filling. You might never make regular lemon bars again! A white cake mix simplifies the crust preparation. We also have a fantastic recipe for a traditional Lemon Bar with homemade crust.


  • For the crust:
  • 1-1/2 cups sweetened coconut flakes

  • 1 box white cake mix

  • 1/2 cup unsalted butter, melted

  • For the filling:
  • 2 cups granulated sugar

  • 1/2 cup all-purpose flour

  • 1 teaspoon baking powder

  • 4 large eggs

  • 1 tablespoon freshly grated lime peel

  • 1/3 cup fresh lime juice*

  • 1/3 cup fresh lemon juice*

  • For the garnish:
  • powdered sugar or 1 cup sweetened coconut flakes


  • Pre-heat oven to 350 F. Line a 9×13″ baking pan with foil, letting ends extend above pan. Spray lightly with cooking spray.
  • Make the crust:
  • To make the crust, spread coconut on a baking sheet. Bake 8 minutes, stirring once, until lightly toasted. Let cool. In a food processor, pulse together cake mix and melted butter until evenly moistened and crumbs form. Stir in coconut. Press mixture evenly into the bottom of the foil-lined baking pan. Bake 10-12 minutes until crust just begins to lightly brown at edges.
  • Make the filling:
  • To make the filling, whisk sugar, flour and baking powder in a large bowl to combine. Whisk in eggs, lime peel and juices until well blended. Pour over hot crust. Garnish with either powdered sugar or more coconut flakes. Bake 25 minutes or until topping is golden brown and set. Cool completely in pan on a wire rack. Holding foil ends, lift the whole thing out of the baking plan and place on a cutting board. Allow to cool thoroughly.


  • You can use all lemon juice, all lime juice, or all key lime juice!

Delicious! I adapted the receipe a little and used a sugar substitute in the filling. Plus I made the powdered sugar using a sugar substitute. I was a little nervous about the finished product but it was wonderful! I will definately be making them again.

My family loved this recipe! They have just the right amount of sweetness and tartness. It was so easy and quick to prepare. I would definately make them again.
