Key Lime Pie Fudge

This Key Lime Pie Fudge is the best creamy, tangy, and sweet homemade fudge with the best pop of citrus and a buttery graham cracker crust. It tastes like a slice of Key Lime Pie in fudge form and is the perfect treat that feels like spring!

Ingredients

For the Graham Cracker Crust: (optional)

6 Whole Graham Crackers (1/2 cup crumbs)
3 TBS Melted Butter
1 TBS Granulated Sugar

For the Key Lime Fudge:

3 cups White Chocolate Chips (High quality like Ghiradelli)
14 oz Sweetened Condensed Milk
2 TBS Unsalted Butter
2 TBS Key Lime Juice
1 1/2 tsp Lime Zest
1/2 tsp Vanilla Extract

Instructions

For the Graham Cracker Crust: (optional)

Preheat the oven to 350 degrees Fahrenheit. Line a 9x9 in baking pan with parchment paper, and set it aside.
Blend the Graham Crackers in a blender or food processor until you have a fine crumb. Add them to a medium bowl with the Melted Butter and Granulated Sugar. Stir together until combined. 6 Whole Graham Crackers, 3 TBS Melted Butter, 1 TBS Granulated Sugar
Press the mixture evenly into the bottom of the prepared baking pan. Bake for 7-8 minutes until golden brown. Remove from the oven and set aside to cool.

For the Key Lime Fudge:

Add the White Chocolate, Sweetened Condensed Milk, and Butter to a large microwave safe bowl and microwave in 30 second increments until you can stir it all the way smooth. 3 cups White Chocolate Chips, 14 oz Sweetened Condensed Milk, 2 TBS Unsalted Butter
Add the Key Lime Juice, Lime Zest, and Vanilla Extract to the mixture and stir it until evenly mixed in. 2 TBS Key Lime Juice, 1 1/2 tsp Lime Zest, 1/2 tsp Vanilla Extract
Pour the fudge into the square pan over the graham cracker crust. Smooth out the fudge to the corners and the top is even.
Cover the pan and place it in the fridge for at least 3 hours, or let it sit at room temperature for several hours.
Remove from the fridge once chilled and lift the fudge out of the pan. Cut the fudge into small pieces with a sharp knife, and enjoy.

Notes

Line your Pan: Line your square pan with parchment paper so you can easily lift the fudge out of the pan when its done, and slice it up easily.
High Quality Ingredients: Use good, high quality ingredients to improve the taste and texture of your fudge. Especially when it comes to the white chocolate chips. I love the Ghiradelli Classic White Vanilla Flavored Chips.
Stove Top Method: Instead of making this in the microwave, add the white chocolate, condensed milk, and butter to a small sauce pan and heat it on the stove top over medium heat. Stir until it is well melted and smooth, then stir in the lime juice and zest.
