Weirdly, as much as I love limes, I’m not the biggest fan of lime related desserts. BUT, my boyfriend is and if he wants something key limey, I will bake it for him! I remember getting a key lime cheesecake at Magnolia Bakery a few years ago and remembered that he liked it.
So thankfully, Magnolia Bakery posted their recipe for one of their sweet and tart lime treats: their key lime ice box bar. Obviously, I had to make it.
So, let’s get baking!
How to Make Magnolia Bakery Key Lime Ice Box Bars
INGREDIENTS FOR CRUST
2 cups graham cracker crumbs
1/2 cup brown sugar
1/4 cup melted butter
INGREDIENTS FOR KEY LIME FILLING
42 ounces sweetened condensed milk
12 egg yolks
2 cups key lime juice
2 tablespoons fresh lime zest
2 cups heavy cream
2 tablespoons sugar
2 teaspoons vanilla extract
2 tablespoons fresh lime zest (for garnish)
MY ADJUSTMENTS TO THE KEY LIME ICE BOX BARS RECIPE
I cut the recipe in half for the key lime filling and instead of creating bars, I put the ingredients in baking cups.
However, I didn’t half the portion for the graham cracker crust because that’s Greg’s favorite part! I wanted to make sure he had a good amount of the crust with some tangy key lime filling.
Lastly, I added a few extra squeezes of lime juice and a few more gratings of lime zest to make the bars a bit more zesty and tart.
INSTRUCTIONS FOR CRUST
Preheat the oven to 300 degrees Fahrenheit.
Mash the graham cracker so you get crumbs. Then in a small bowl, add the graham cracker crumbs, brown sugar, and melted butter. Mix to combine.
Gently press the crust in an ungreased pan (or in my case, each baking cup).
Bake for 15 minutes. Then, remove from the oven and place on a wire rack to cool completely.
While the crust was cooling, I started working on the key lime filling.
INSTRUCTIONS FOR KEY LIME FILLING
Make sure the oven is still heated at 300 degrees Fahrenheit.
In a medium bowl, whisk together the sweetened condensed milk, egg yolks, lime juice, and lime zest.
Pour mixture into the cooled graham cracker crust. Then, bake for 25-30 minutes or until the middle has set, but still jiggles slightly if touched.
Remove from the oven and place the bars on a wire rack to cool completely.
Meanwhile, in a mixer bowl fitted with a whisk attachment, combine the heavy cream, vanilla, and sugar. Whip just until medium soft peaks have formed.
Spread the whipped cream over the top of the cooled key lime filling and sprinkle with lime zest as garnish.
Greg seemed to enjoy these bars and they were really easy to make! Let me know what you all think of these vibrant, zesty treats; they’re perfect for the hot, summer days!
