Why You Must Make

  • Lime and coconut are a delicious tropical pairing.
  • This is an easy, elegant dessert that tastes amazing, too.
  • If you love Key lime pie, you’ll adore these bars.

I definitely wasn’t very creative this month with our Dessert Challenge ingredients of  Lime and Coconut. I was self-serving, though. I adore Key lime pie…and, of course, the hubby does not. Lemon Meringue, yes. Key Lime, no. My parents made us slushy virgin daiquiris when we were children…another foodie memory I’d forgotten till my fingers hit the keyboard. Those helped usurp lemon’s spot as my favorite dessert citrus.

Recipe Tips

I was making desserts for the show house (again) and needed a non-chocolate dessert to go along with my milky way brownies (which you will see on Sunday)…and guess what came to mind? Yup, these Key Lime Bars with Coconut Crust were perfect. They’re fine with just plain ol’ lime juice if Key limes aren’t in season, or if you don’t want to substitute bottled Key lime juice for fresh.

Thanks to Sheryl, of Lady Behind the Curtain, for hosting our Dessert Challenge each month. Stay tuned as June brings one of my favorite combinations: raspberries and strawberries. But until then, I hope you’ll try these tropical-inspired key lime bars with coconut crust. I could have eaten the whole batch myself!
