Key Lime Fudge

Today I’m sharing what looks to be a very spring-like recipe for:   Key Lime Fudge

Key Lime Fudge #recipe

The best part of spring is the green.  Where I live now (near Lake Tahoe) everything but the tall pine trees turns rather brown in the winter and the land looks pretty bare.  The lawn goes dormant, the flowers die and most of the rest of the plants drop their leaves.  It’s not such a pretty sight unless there is snow covering the ground.  77 degree temps tell me that winter is over and spring has sprung.  We didn’t have a terribly cold winter anyways this year, so the grass is on its way to green, and I’m getting ready to plant some new plants and flowers that I’ll be hoping the deer and squirrels won’t be excited to eat.   Green is where it’s at.  Green makes me happy.  Key Lime Fudge is barely green, but it makes the cut and it’s a yummy spring green confection.

Have you ever picked up a bag of key limes?  They’re awfully cute.  They’re tiny little things.  You’ve gotta squeeze the heck out of them to get every bit of their juice, but it’s all worth it.  They have a stronger scent and a thinner rind than the typical lime.  The flavor is more tart and bitter.  These limes present themselves nicely in sweet treats (like key lime pie!) since the sugar balances out that tart flavor and highlights the unique flavor of the key lime.  I love them!  

Key Lime Fudge

You can most certainly use regular limes for this fudge.  They might give the fudge a slightly sweeter flavor, but all will still be good.  Don’t skimp on the lime zest in this recipe since it gives the fudge a fabulous green tint, and it adds a good amount of lime flavor to the recipe too.  So if you’re wishing for a little “spring” in your life and it hasn’t quite arrived yet, treat yourself to some Key Lime Fudge instead.  Enjoy!

Key Lime Fudge

Ingredients:

One 5-ounce can evaporated milk (2% or whole)
1 2/3 cups granulated white sugar
1/2 teaspoon salt
12 large marshmallows (halved)
2 cups white chocolate chips (I used Whole Foods mini chips)
1/4 cup grated lime zest (about 5 limes)
2 tablespoons Key lime juice (5 to 7 limes, juiced)

Directions:

1. Line an 8" x 8" square pan with aluminum foil; grease the foil with butter. It's not a good recipe for a 9-inch square pan as the fudge will be too thin.

2. Combine the milk, sugar and salt in a large heavy saucepan over medium heat. Stir and bring to a boil; boil 8 minutes, stirring constantly at a boil (if you have a candy thermometer, you can bring it to the soft-ball-stage, but I didn't use one). Remove the pan from heat. Add the marshmallows, chocolate, zest and juice, and stir until the marshmallows and chocolate are melted and the mixture is smooth. Scrape the fudge into the prepared pan. Tip the pan to make sure the fudge covers the bottom evenly. Cool completely, then cut into 1-inch squares.

Tips:

*This recipe can be made with regular limes too.

    I made key lime pie bars a few weeks ago with key limes. Never again will I be juicing 25 of those little ping pong balls. LOL. So I would love to just snag a few pieces of your fudge right off that plate! Gorgeous 🙂

    Well now, I love lime. I love marsmallows, and I love fudge. It follows therefore that I am going to like this! It sounds yummy!

    I love the flavor of key lime but they are SO TINY! I am impressed that you went ahead and squeezed enough to get so much juice for these! i’m sure these are the best sweet tart fudge bites.

    That looks amazing. Just thinking about key limes makes me salivate!

    They do sell key lime juice in the grocery stores around here. That makes these recipes so much easier, because they don’ t always stock the limes themselves.

    I’m a key lime fanatic, and I love the flecks of green throughout this fudge. This must be so delicious!

    I made this wonderfully delicious Key Lime Fudge for a St. Patrick’s Day potluck at work. I followed the recipe exactly and it was wonderful! I took home an empty pan and was given high fives by all my co-workers! As always, Lori, thank you for sharing this scrumptious fudge recipe with all of us bakers!

    I use Nellie and Joe’s Key West Lime Juice instead of juicing any limes.

    It is delicious!

    What is the shelflife of the fudge? Must it be refridgerated?

    • August 20th, 2014 @ 8:13 AM

      No need to refrigerate. Just keep it in a tightly covered container.

    How long should it take for the fudge to set? I made these last night around 8pm and this morning it’s still soft. Did I not heat the condensed milk to a high enough temperature?

    Thanks!

      Texture problems usually have something to do with temperature- perhaps wasn’t quite there yet, as you mentioned.

    One 5-ounce can evaporated milk (2% or whole) So can I use regular milk and not canned? I feel funny about asking but unsure as you have (2% or whole).

    • May 29th, 2015 @ 6:39 AM

      no- you definitely need to use evaporated milk… either the whole or the 2%.

    Hey there! I changed the recipe just a tad… Instead of using 12 large marshmallows, I used a small container of fluff! I couldn’t find key limes so I just used limes… It’s delicious! So I guess you’d call it lime fudge? Anyways, I was very pleased with this recipe! Oh and I only boiled it for 6 minutes instead of 8.. Was scared to overlook bc my stove is a flat top and it can tend to over cook at times! When I’m able to get some key limes I will definitely try this original recipe! Thank you so much for this!!!

    I buy Nellie & Joe’s “famous” Key West Lime Juice. I find it right next to the concentrated lemon juice at Fry’s grocery store. It’s just as good as the fresh and it saves all that time squeezing!

    I had an issue with my sugar mixture instantly hardening as soon as I added the chocolate chips. I put it back in low heat just so I could incorporate everything but could not get the sugar lumps out. Any ideas on what I did wrong so that I don’t have this issue when I make it again?

    • March 29th, 2016 @ 1:22 PM

      I’m not sure… fudge can be tricky. Hard to pinpoint what went wrong, but it usually has to do with the temperature.

    Question: About how many ounces is 2 cups of white chocolate?  I’m in another country and can only buy white chocolate in a bar form.  Thanks

    • April 19th, 2016 @ 1:43 PM

      I’m not sure I can answer that… does the bar have a number of ounces on it? Perhaps you can make an estimate if you have that information.

  35. postedApr 19, 2016 6:31 PM

    I don’t know how to reply to your reply; so I’ll just post again.  The bar is 1 pound.  The issue is that 1 cup of chips isn’t the same as 1 cup (8 oz) of chocolate because the chips don’t fill all those little spaces.  I figured that if your bag had an amount of ounces on it, maybe you could do a better estimate than I could as to how many ounces are in 2 cups of chips.

    Annalisa-
    A bag of chocolate chips is usually right at 2 cups and weighs 12 ounces.

    Love key lime pie and cake and buy key lime juice from Kermit’s (Key West, FL). Was wondering if you could substitute one seven-ounce jar of marshmallow creme in place of the 12 large marshmallows? Also, are the marshmallows the regular size or are they the large (huge) size as I refer to the marshmallows as miniature, regular and extra large? I am surprised the recipe does not call for any butter/margarine, other than the evaporated milk what prevents the mixture from burning when boiling the sugar, milk and salt for that amount of time (8 minutes at boiling)? Thanks.

    • May 13th, 2016 @ 6:34 AM

      I’m not sure about the marshmallow creme sub as I have not tried that. Regular, large marshmallows- not jumbo. The recipe comes from an old Southern Living magazine… so I’m not sure about your last question. Good luck!
