Hello! I’m Amelia, welcome to Ritzy recipes. My love for cooking started from a very personal journey when my first child was eight years old. He went through a difficult period of illness, and his doctor advised me to pay close attention to his nutrition. While I learned to cook wholesome meals, I also discovered that a bright, zesty dessert can lift the mood of the whole house. Today, I’m sharing a recipe that is pure sunshine in a pan: my 4-Ingredient Lemon Icebox Pie.
Next, let me tell you, when the Georgia heat starts rising, this easy no-bake lemon pie is the only thing I want in my freezer. It is a refreshing no-bake citrus pie that perfectly balances tartness and sweetness. This quick summer lemon dessert has been a staple at our family barbecues for years because it takes almost zero effort to prepare. If you are looking for a lemonade pie with 4 ingredients that tastes like a professional bakery made it, you are in the right place!
Also, this eggless lemon icebox pie is incredibly stable and creamy, making it a favorite for potlucks. It features a buttery lemon pie with graham cracker crust and a silky sweetened condensed milk lemon dessert center. You don’t need to be an expert to throw down in the kitchen and create this masterpiece. Then, grab a glass of sweet tea, and let’s get started on this 4-Ingredient Lemon Icebox Pie!
What You Need for This Frozen Lemon Pie Recipe
Before we start mixing, let’s look at our short and sweet shopping list. Since we only have four items, I always recommend getting the best quality you can find.
- 1.5 cups Graham Cracker Crumbs: To build our lemon pie with graham cracker crust.
- 1/3 cup Melted Butter: To bind the crumbs together.
- 1 can (14 oz) Sweetened Condensed Milk: The heart of this sweetened condensed milk lemon dessert.
- 1/2 cup Fresh Lemon Juice: Plus some zest for that authentic “icebox” tang.
Next, make sure you have a 9-inch pie plate ready. Also, if you’re a fan of citrus, you’ll definitely want to try my homemade limoncello or perhaps my brazilian lemonade recipe.
How to Make 4-Ingredient Lemon Icebox Pie
Step 1: Preparing the Graham Cracker Foundation

First, mix your graham cracker crumbs with the melted butter in a small bowl. Then, press the mixture firmly into the bottom and up the sides of your pie dish. I find that using the back of a measuring cup helps get a perfectly even layer.
Next, place the crust in the freezer for about 10 minutes. This ensures your easy no-bake lemon pie has a sturdy base that won’t crumble when you slice it. If you enjoy a crunchy base, you might also like my bacon crackers recipe for a different kind of snack.
Step 2: Mixing the 3-Ingredient Citrus Filling
Then, in a large bowl, whisk together the sweetened condensed milk, lemon juice, and lemon zest. Next, you will notice the mixture thickening almost instantly. This is a natural reaction between the acid in the lemon and the proteins in the milk.
Also, stir it until it is completely smooth and glossy. This eggless lemon icebox pie filling is so delicious you’ll want to eat it with a spoon! For more creamy inspiration, my easy 3 ingredient chocolate mousse is another quick winner.

Step 3: The Magic of the Freezer Set
Next, pour the lemon mixture into your prepared crust and smooth the top. Then, wrap the dish tightly in plastic wrap. This frozen lemon pie recipe needs time to reach that perfect, sliceable consistency.
Finally, place the pie in the freezer for at least 4 to 6 hours. While it sets, why not prep some slow cooker cowboy casserole for a hearty meal later? This refreshing no-bake citrus pie is the perfect way to end a heavy dinner.
Pro Tips for the Best Quick Summer Lemon Dessert
Choosing Your Juice
Next, let’s talk about the lemon juice. Can I use bottled lemon juice instead of fresh lemons? While fresh lemon juice provides the brightest and most authentic flavor, you can use bottled lemon juice in a pinch. If you do, try to use a high-quality 100% juice brand. Note that you will miss out on the fresh lemon zest, which adds a significant amount of aromatic citrus oil.
Then, let’s discuss the crust. Can I use a different type of crust? Absolutely. While a lemon pie with graham cracker crust is traditional, this filling pairs beautifully with a Golden Oreo crust or a shortbread cookie crust. If you prefer a salty-sweet combination, a crushed pretzel crust also works well. If you love cookies, check out my crumbl cookie recipe.
FAQs
To achieve the classic “icebox” consistency, the pie should be frozen for at least 4 to 6 hours. For the best results and the easiest slicing, freezing it overnight is recommended. This ensures the sweetened condensed milk lemon dessert has fully set into a firm, creamy texture.
Because of the high sugar content and the stability of the mixture, this pie holds its shape better than traditional ice cream. However, it is best served chilled. It is recommended to take it out of the freezer about 10–15 minutes before serving to allow it to soften just enough to bite through easily. For more chilled treats, see my fudge popsicles.
Also, adding a layer of whipped topping before serving makes it look even more like a lemonade pie with 4 ingredients from a diner. I like to add a few thin lemon slices on top for a beautiful presentation. If you enjoy whipped toppings, you’ll love my strawberry mousse.
