Key Lime Meltaway Shortbread

Key Lime Meltaway shortbread cookies lined up on a plate

Sometimes I like simple things.

A hug from my kids.

A good book.

Sleeping in.

And while I make crazy desserts with lots of stuff put in them, sometimes I just like a simple cookie.

With citrus.

It’s true.

The problem with lemon, orange or key lime desserts in my house is that no one likes them except me.

Which translates into me eating almost the entire tray of cookies and then self-loathing for not being able to stop eating cookies and swearing that I will never eat another cookie until I reach my goal weight…and then going back and eating the last cookie because it would be wrong to leave just one on the plate and that starting TOMORROW…

BAH!

I gave my husband one of these cookies to try and he literally made the worst possible scrunched up face I have ever seen, like I was feeding him poison or something and said, “AAHH, What ARE these…YUCK!

I keep trying to convince him citrus is cool, but I really need to find a new battle.

So I try not to make simple, citrusy cookies.

But I made an exception this week.  Because it’s Mother’s Day on Sunday and if there’s ever a day to self-loathe…wait…that didn’t come out right.

The thing about these cookies, please know, that they are “Meltaways” which means they have cornstarch in them giving them a soft, melty texture.

I love meltaways.  LOVE.

My husband does not, however…remember the scrunched up poison face?

But since this is my site, not his, I say make them, eat them and love every second of it!

First make your dough. It’s simple, just a few ingredients…
Then divide it in half and roll it into 2 equal 10″ logs…I hate the word log.
Wrap those in cling wrap and stick in the fridge for a few hours…
When they are nice and chilled, slice them with a sharp knife…
And bake them on a parchment lined baking sheet.
When they are done and cooled, you need to make the glaze.
Throw it all in a bowl and stir it up…
Spoon a little on your cookie…
And then smush it around a little.
And let them set up.
Then you can eat them and decide if meltaways are for you, or if they cause you to make scrunched up poison faces.

  1. I love these! My only issue is that the glaze frosting melts off of them if the are not eaten within 10 min right out of the fridge. Is it just because I live in a Florida and its hot or is this how they are normally?

  2. I made 2 batches of these yummy looking cookies. Gonna bake them up tomorrow and wash them down with a corona ????……my hubby and I are crazy about lime and can’t wait to try!,

  3. These are fantastic with or without the lime! I’ve also made them with orange juice and orange zest. ๐Ÿ™‚ I’m baking another batch tomorrow for Thanksgiving; I’m going to indent them and make mini cheesecakes! I feel like there are so many things you can make with this as a base. Thank you for such a fantastic and versatile recipe!!

    I made meltaways the other day since i was Craving sweets and only had powdered sugari guess i am lucky since my husband adores anything key lime:)ill be naking these tomorrow!

  5. I loved these cookies. I had made my best friend the most amazing key lime cake a few years ago and she still yearns for it. Unfortunately, we are now on opposite coasts so I was looking for a “mailable” cookie to ship in its’ place. Your cookie was the perfect substitute. In fact, it wasn’t a substitute but a solid alternative that she can’t stop eating. ๐Ÿ™‚ I am about to publish my blog (www.scrambledsundays.com) in the next few months and I would like to feature these with an appropriate link to your blog. It will feature my own pics. Would this be ok? Thank you again for introducting these to me. I look forward to discovering more of your treats!

    I made these for a tailgate last week – they were delicious and everyone loved them. They reminded me of margaritas in a cookie. Thanks for sharing!! ๐Ÿ™‚

  7. 2 things – you’re hubby is crazy and these are delicious!!!! I was a bit too impatient this afternoon so they didn’t turn out in perfect cookie form. But they still tasted amazing!

  8. I made these, and they are delicious. However, I have to point out the wonky math — you say these make approx. 24 cookies, but you roll the dough into two 10″ logs and then slice each cookie 1/4″ thick. If you’re really making them 1/4″ thick (they look thicker than that in your pictures), then that yields 80 cookies.

    1. I agree. Itโ€™s mathematically impossible to cut 20โ€ of dough into 1/4โ€ slices and end up with only 24 cookies. However this doesnโ€™t detract from the delicious taste of these cookies.
