Do you love the fresh citrus flavor of key lime pie?

Yes! Well this key lime fudge with it’s intense citrus flavor beautifully balanced with undertones of vanilla cream will definitely be one of your favorite recipes here at How To Make Easy Fudge. It is so good and so easy to make.

No need to peel, zest, or even squeeze a lime to make this easy key lime fudge. You simply melt white chocolate chips and some store bought key lime curd together in the microwave.

This homemade fudge is uniquely refreshing and has a pretty pastel green color so it would make a lovely dessert to serve at a spring or summer party.

It would also make a wonderful gift along with some pretty pastel Lemon Fudge, Orange Creamsicle Fudge or Strawberry Fudge.

What makes this key lime fudge so easy to make?

  • It’s made with just 2 ingredients: white chocolate chips and key lime curd.

What is key lime curd?

  • Key lime curd is a creamy smooth, intensely flavored, somewhat tart, somewhat sweet, cross between a lime jelly and a lime custard.
  • Key lime curd is made using egg yolks, butter, sugar, and real key lime juice.
  • You can make homemade key lime curd or you can just buy jars of it at the grocery store or order it online.

Can I use lime curd?

  • Yes, if you are able to find lime curd in your grocery store then by all means go ahead and use it. Your lime fudge will taste fantastic.
  • Dickinson’s Lime Curd is available in many grocery stores and it tastes great in this easy fudge recipe. Just be sure to buy two 10 ounce jars as you’ll need 1 1/3 cups to make this fudge.

What is the difference between Persian limes and key limes?

  • Persian Limes, those that you find in the grocery store next to the lemons, are typically 2-3 inches in diameter, have thick dark green skin, and a nice lime flavor.
  • Key Limes are much smaller, usually 1-1/2 inches in diameter, have thin, leathery skin, and a very acidic, intense, slightly herbal, lime flavor.

Can I use real key limes to flavor my fudge?

  • I really love that this fudge is essentially flavored with real key limes being key lime curd is made with real key limes. If you want to use fresh key limes to make this lime fudge, then you will need to make curd first.
  • You could possibly use our vanilla fudge recipe which blends together white chocolate and sweetened condensed milk then add key lime juice and zest to it, but you’d have to adjust the amount of white chocolate to thicken the fudge.
    • I have not tried this so I do not know what the ratios of juice to chocolate and sweetened condensed milk would be.
    • If you give it a try I’d love to hear about it in the comments below.

How to make easy key lime fudge.

  1. Stir 1 1/3 cups of key lime curd into white chocolate.
  2. Melt in the microwave.
    • Heat at 70% power for 90 seconds then let the bowl rest in the microwave for about 3 minutes before stirring.
  3. Add green food coloring and continue to stir until the white chocolate chips melt.
  4. If needed, you can heat for an additional 10-15 seconds.
    1. It’s best to allow the residual heat from the hot melted white chocolate to melt the remaining chips.
    2. Just let the bowl sit for another minute to allow the heat to continue to melt the chocolate then stir again.
    3. If you over-heat the white chocolate, the fudge may become greasy. If this happens be sure to check out our Easy Fudge FAQ page.
  5. Once all the chips have melted, pour the fudge into an 8-inch pan that is either lined with non-stick tin foil or parchment paper or buttered well.

That’s it!  This lime fudge is seriously so easy to make and it has such a lovely flavor. No one will ever guess it took you less than 10 minutes to make it.

What type of white chocolate should be used to make key lime fudge?

  • I developed this recipe using Nestle Premier White Chips which made a wonderfully flavored fudge.
    • Nestle white “chocolate” chips, are actually considered a confectionery coating because they are made using a vegetable oil (palm kernel oil) instead of cocoa butter which is used to make pure white chocolate.
    • You can use pure white chocolate chips (made with cocoa butter) to make this fudge but know that you will need to use more white chocolate than confectionery coating in order for your fudge to set up property and that the lime flavor will not be quite as intense because the flavor of the cocoa butter will mute the lime flavor slightly.
    • You can also use other types of white confectionery coating like White Candy Melts, Merckens White Wafers, White Almond Bark, Ghirardelli White Melting Wafers, or Peter’s Ice Caps (one of my personal favorites).

NOTE:

  • White chocolate is a bit softer than white confectionery coating so you’ll need to adjust the recipe accordingly.
  • If using white confectionery coating chips (no cocoa butter listed in the ingredients) use 24 ounces, if using pure white chocolate (with cocoa butter listed in the ingredients) then use 28 ounces.

You can find the Nestle White Chips or Peter’s Ice Caps and the key lime curd in a single jar or multi-pack on amazon (commission earned for sales at no extra cost to you).
