KEY LIME PIE FUDGE

It’s winter in the rest of the country but in South Florida we are basking in 80 degree weather and even hit up the beach yesterday. I’m sorry. I’m not trying to rub it in. I’m a warm weather girl at heart and I remember those brutal Utah winters from my college years and I can’t go back. It literally makes me cry. I didn’t take my coat off for four years even in my house.

Maybe this post is more for you guys than me. Do you need to make some key lime pie fudge to make you think you’re in a tropical paradise? I thought you did. If that’s true you might also dig this Key Lime Pie on a Stick or these Coconut Lime Swig Cookies.

Spring will come I promise. Then summer will come and you will be the one laughing at me with the hurricanes and the profuse sweating.

It took a couple of tries to get the Key Lime Pie Fudge right. My first batch the crust just crumbled. Not enough butter. I also had too much white chocolate so it was a really firm fudge. Almost dry.

My other problem is that it didn’t have enough tang. If you’re a key lime pie purist you know that any good key lime pie has a good tart edge.

If you want your pie mild then you actually want this Lemon Pie. It’s fine. It’s good too. But it’s not Key Lime Pie.

TIPS FOR MAKING THIS KEY LIME PIE FUDGE

  • Don’t skimp on the lime zest. It takes a good 4-5 limes to get enough zest for the fudge. Be patient and use a microplane. It will make your life a lot easier.
  • Use good white chocolate. You can use all white chocolate chips if you want for this recipe but for the creamiest fudge use a mixture of white chocolate chips and a white chocolate bar like Lindt.
  • Don’t overheat the chocolate. White chocolate is a little more temperamental and does not liked to be heated too much or it will seize.

CAN I USE AN 8″ PAN?

I’ve made it with an 8″ pan and it can be done but the fudge will be a lot thicker. In my opinion the ratio of crust to fudge is better when you use a 9″ pan.

This Creamy Key Lime Pie Fudge has a thick graham cracker crust and a tangy key lime pie filling. 

Ingredients

  • 1 1/4 cups graham cracker crumbs
  • 6 tablespoons butter, melted
  • 1/4 cup white sugar
  • 1 (14 ounce) can sweetened condensed milk
  • 1 (11 ounce) bag white chocolate chips
  • 1 (4.4 ounce) bar white chocolate (like Lindt)
  • 1/4 teaspoon salt
  • 2 tablespoons lime zest (about 4-5 limes)
  • 1/4 cup lime juice

Instructions

Preheat oven to 350 degrees and completely line a 9" square pan with foil or parchment paper. Spray with cooking spray.

In a medium bowl, combine graham cracker crumbs, sugar, and butter until it's fully combined and the texture of wet sand. Pour into prepared pan and press into an even layer using the bottom of a measuring cup or hands. Bake for 6-8 minutes or until crust starts to turn golden brown. Cool completely.

Once crust has cooled, make the filling. In a microwave safe bowl, add the sweetened condensed milk, white chocolate chips, and white chocolate bar, and salt. Heat in 30 second intervals in the microwave stirring in between until chocolate is melted and smooth.

Stir in the lime zest and lime juice. Pour over cooled crust. Chill fudge in the refrigerator for 1-2 hours or until firm. Slice into small squares and serve.

Fudge will keep in the fridge for at least a week in an airtight container.
