Who knew there is such a thing as 5 ingredient Key Lime Pie!
Well, leave it to my Grandma to know!
One of my favorite treasures is an old wooden recipe box that belonged to my grandmother. I can sit and reread those recipe cards
over and over, filled with delight as I see her handwriting and remembering how much I enjoyed cooking with her in the kitchen.
I stumbled across this recipe in her collection and I couldn’t believe how easy it seemed. Only 5 ingredients and no bake? I’m in!
The best surprise was the decadence of this dessert. A little goes a long way, but your tastebuds will thank you.
White Chocolate Key Lime Pie

Ingredients
- 1 cup whipping cream
- 1 (12-oz) bag vanilla/white chocolate chips
- 1 Tbsp sour cream
- 1/2–1 tsp lime zest (or more, to taste)
- 1/3 cup bottled key lime juice
- 9” ready-made graham cracker crust or premade mini graham crusts
- Fresh raspberries (optional garnish)
- Lime slices (optional garnish)
- Whipped cream (optional garnish)
Directions
- Put the cream and chips in a small saucepan and melt down the morsels over low heat. (Make sure to keep heat low, so you don’t scald the cream or burn the chips.) This will take about 5 minutes. I like to use a whisk to make sure mixture is smooth.
- Remove the pan from the heat and stir in the remaining ingredients. Whisk ingredients together. Pour the mixture into the crust and refrigerate the pie for at least 8 hours, or overnight. If you’re using the mini crusts, this will make 8. The pack is usually 6, so I’ll make the 6 and then make “crustless” for the other two. It’s more like a key lime custard dessert…still so good!
- Garnish the pie with the fresh raspberries, lime slices, or whipped cream.
Here’s how I make the crustless version of this 5 ingredient key lime pie with the leftover filling when I’m making the minis. Tart, sweet and creamy all at the same time!

This dessert was a hit with my friends. Made the mini pies which was perfect. No need for cutting into a pie. Was wondering if the pies could be frozen so they can sit out a little longer on the serving table before melting

Yes! Great idea and should work fine!

My husband is a diabetic so even though they look delish can’t make them.

Do you think something similar with lemons would work?
justjillbauer
Yes!! I’ve taken this concept and made lemon blueberry. Will be posting soon!!

Jill,
Is this a heavy whipping cream you are using in here or like boxed whipped topping? I make your blueberry lemon no bake pie all the time yum! Would love to make this too.,
justjillbauer
Heavy whipping cream…same as lemon blueberry!

Oh Jill…I’m going to make this tonight! I am diabetic so I will make some adjustments and use sugar free Vanilla/White Chocolate Chips (which I have) and leave out the graham cracker crust. All other ingredients will work fine! I love key lime…so I’m looking forward to this treat! Thanks for sharing your Grandmother’s recipe!

I am back to say that I made this with sugar free white chocolate chips and poured the filling into individual ramekins…no crust. I put a couple of fresh raspberries on top, too. It worked perfectly and was so delicious! Anyone who needs to avoid sugar will love how this recipe worked. I used a combination of “Bake Believe” sugar free white chocolate baking chips (from Walmart) and “Choc Zero” White Chocolate chips (from their website). OMG…so good!.
Cindi
I should clarify that the “Choc Zero” white chocolate chips are also sugar free.

May have to try this. Not sure if I can find key lime juice in stores. Will check it out. We have given up carbs, so will try your custard version. Was so happy to see that you included that in your instructions.
Thank you for sharing. Happy Monday!

Key lime juice is in the juice aisle next to lemon juice. Easier to find than you might think.
