These Key Lime Bars are sweet, tangy and absolutely delicious. Topped with fresh whipped cream and toasted coconut, they’re super refreshing on a hot summer day.

You guys. These bars!! I am completely in love.
Velvety, smooth, silky, sweet, slightly tangy. They are ridiculously good!
When I saw that these bars have TWO cans of sweetened condensed milk in them, I was completely sold and had zero doubts about how good they would be. You should all know by now how I feel about that stuff. It’s the nectar of the gods!

A buttery graham cracker crust topped with the most decadent and luscious lime filling and then finished off with fresh whipped cream. They are phenomenal and my boys would agree with me 110%!The texture of these bars is so silky smooth. They kind of just melt in your mouth. I highly recommend the toasted coconut on top.

Light and refreshing, they are absolutely the perfect dessert for summer. These bars are so simple to make. Just make sure you plan ahead because they do need to chill several hours or overnight is even better.
Even though these are called Key Lime Bars, you can certainly use regular limes if you don’t feel like juicing 87 of those little key limes. I’m pretty sure and no one will ever know.
