{No Bake} Key Lime Meltaways

Sweet and tart key lime bars on a crumbled sugar cookie crust – these Key Lime Meltaways literally melt in your mouth…and are sure to leave you wanting more!

I’m not sure I’ve ever met someone who loves key lime as much as I do. And not just because it’s the perfect sweet-tart combination, or because it’s most often eaten in the form of a pie, but because, for me, it brings back instant memories of my honeymoon. It’s hard to believe my honeymoon was nearly 9 years ago now….in some ways, it feels just like yesterday! I remember so much of it – riding bikes around Sanibel Island, lying on the beach for an entire afternoon, eating endless baskets of crab legs, playing cards late at night by the pool, collecting seashells at Captiva beach……

…..and sampling the key lime pie at every restaurant we could! We both discovered a love for it early on and decided we would try all the different variations that Sanibel & Captiva Islands had to offer. Needless to say, between the baskets of crab legs dipped in melted butter, the pina coladas and strawberry daquiris, and the countless pieces of key lime pie, we were both completely stuffed by the end of our trip! Completely stuffed and completely ready to get back and start our lives together.

There are so many things in life that feel like they fly by and leave you wanting more. And you know what? My honeymoon wasn’t one of them! That sounds bad….I know. Don’t get me wrong – I loved every minute of it! And I would go back and do it all over in a heartbeat! But. At the beginning of our honeymoon I made a conscious decision to NOT let it fly by. I decided I would pay attention to the moments….and I hoped they would somehow last longer if I did.

And so, as we were riding our bikes around the island, I was taking a mental snapshot of the palm trees and stopping to feel the wind blow through my hair. As we were lying on the beach, I was smelling the salty air and committing to memory the feeling of the Florida sun on my back. And as we were enjoying our 18th piece of key lime pie (only a slight exaggeration) I was looking at the man across from me and realizing that I didn’t need anything more – I already had enough! Unfortunately, the same can’t be said about these Key Lime Meltaways. These sweet little bars leave you wanting more, each and every time. I guess some things are just like that.

    These just look so SO good, Cathy! I could easily make them dairy free by subbing the butter with dairy free sticks! Pinning this and sharing on Facebook later! Have a great 4th!

    Cathy, these are a work of art. Key limes apparently are not just ordinary limes, huh? I’ll have to google that….and then MAKE some! Yum.

    Thank you for this recipe. I am going to make these next week. What kind of sugar cookies do you use…homemade or is there a brand you recommend please?

      Hi Lin, I used store bought that were in a sleeve and had a flower shape. The brand was Rippin Good but I’m not sure if they are sold everywhere. Looking online, it seems that they are sold in a number of larger grocery stores and on Amazon. Hope this helps!

    Love the no-bake idea for summer treats. I love lemon bars so this recipe caught my eye. I would be a good alternative to an old favorite.

    I used a dry sugar cookie mix and pressed it into the cups of a mini muffin pan and baked them. Then took them out of the pan let them cool and filled them with this delicious key lime mixture. I followed the recipe exactly except I left out the zest and obviously the sugar cookie part was different. Everyone loved them and I keep pointing them to your website. Thanks for the easy, yummy recipe!

    I actually ended up making these with my partner. While I love the idea, I couldn’t get past the butter taste, as there are 2/3 cups of butter in this one 8×8 pan. I think next time I’ll substitute the butter in the lime mixture with cream cheese and maybe add some cool-whip for some added fluff.

    Thanks for the recipe!

    I made these Key Lime meltaways yesterday with the slight modification that I used coconut sugar cookie crumbs for the crust. They were fantastic! I’ll try the mint Oreo ones as well someday soon. Thanks for the great recipes!

    Looked delicious so I tried recipe, unfortunately almost 24hrs after they had still not set. Mixture was soupy in the begining and so I had added 1/2 c extra powdered sugar. I looked at similar recipe for oreo cream meltaways and noticed it called for 3c powdered sugar and 1/2c of butter.This recipe called for 1/3c butter and 1.5c powdered sugar. So I added 3 Tb soft butter and 1c powdered sugar to mixer then poured topping off into mixer blended it and put back on top of cookies. Mixture was a lot better.
