Ingredients
This Key Lime White Chocolate Cheesecake brings together the perfect balance of tangy citrus and creamy sweetness. I’m always amazed at how the bright key lime juice cuts through the richness of the cream cheese, while the white chocolate adds that luxurious touch that elevates this dessert to something truly special.
Let’s gather everything we need to create this showstopper!
For the crust:
- 1 egg yolk
- 1 tablespoon key lime juice
- 1¼ cups all-purpose flour
- ⅓ cup sugar
- ½ cup butter, cut into small pieces
For the cheesecake filling:
- 3 (8 ounce) packages cream cheese, softened
- ¾ cup sugar
- 1 tablespoon cornstarch
- 3 eggs
- ¼ cup key lime juice
For the berry topping:
- 1 cup strawberries, smashed
- ½ cup raspberry preserves
- ¼ cup water
- 1 tablespoon cornstarch
- Additional fresh strawberries or raspberries for garnish
For the white chocolate mousse:
- 1 cup heavy cream, divided
- ¾ cup white chocolate chips
- ½ (3⅓ ounce) box instant white chocolate pudding mix
When shopping for ingredients, quality matters with this recipe. Look for real key lime juice if possible—it has a distinctive flavor that regular lime juice just can’t match.
And make sure your cream cheese is fully softened before beginning; cold cream cheese will leave you with a lumpy batter that’s nearly impossible to smooth out. Wouldn’t want to ruin such a beautiful dessert with lumps, right?
Directions
Let’s start with the buttery lime-infused crust! Preheat your oven to 350°F and butter the bottom of a 9-inch springform pan. In a medium bowl, combine 1¼ cups all-purpose flour and ⅓ cup sugar, then cut in ½ cup of butter until you have coarse crumbs.
This is where the magic begins—mix 1 egg yolk with 1 tablespoon of key lime juice in a small bowl, then add this tangy mixture to your flour mixture. Blend until moist clumps form, then press the dough into the bottom of your pan. Bake for 20-25 minutes until set and slightly browned at the edges.
For the creamy cheesecake filling, beat 3 packages of softened cream cheese with ¾ cup sugar until smooth and velvety. Can’t stress enough how essential it’s for that cream cheese to be properly softened—cold cream cheese is the enemy of smooth cheesecake, trust me.
Add 1 tablespoon cornstarch and mix well, then incorporate 3 eggs one at a time. Finally, blend in ¼ cup of key lime juice, which gives this cheesecake its signature tangy personality. Pour this luscious filling over your cooled crust and bake for 45-50 minutes until set.
Now here’s a vital step many people miss: when done, turn off the oven, crack the door open, and let the cheesecake rest inside for 30 minutes. This prevents those dreaded cracks from forming. Run a knife around the edge, remove the springform, and let it cool completely before refrigerating overnight.
The finishing touches really make this dessert shine! For the berry topping, smash 1 cup of strawberries and combine them in a small pan with ½ cup raspberry preserves, ¼ cup water, and 1 tablespoon cornstarch.
Bring this mixture to a boil while stirring constantly, then continue boiling for about a minute until thickened. Strain the mixture, cool it down, and spoon it onto the center of your cheesecake, leaving a ¼ to ½ inch border.
For the decadent white chocolate mousse, melt ¾ cup white chocolate chips with ¼ cup cream in the microwave at 70% power, stirring frequently until smooth. In another bowl, beat ¾ cup cream with half a box of instant white chocolate pudding mix for about 2 minutes.
Now here’s a pro tip—mix a spoonful of the cream mixture into the melted white chocolate first, then fold this back into the main mixture. This prevents the chocolate from seizing up. Use this heavenly mousse to decorate the edges of your cheesecake, creating a stunning contrast to the vibrant berry topping.
Substitutions and Variations
For those of you who love tweaking recipes to suit your taste buds, this Key Lime White Chocolate Cheesecake offers plenty of delicious opportunities for customization.
Can’t find key limes? Regular lime juice works perfectly fine, though you might want to use a bit less since it’s more tart.
Not a white chocolate fan? Try dark or milk chocolate chips instead. The strawberry topping can easily become blueberry or blackberry—just swap the fruits and preserves.
For a lighter version, substitute Neufchâtel cheese for regular cream cheese and Greek yogurt for some of the heavy cream.
Feeling adventurous? Add a splash of coconut extract to the filling.
Additional Things to Serve With This Dish
While this decadent Key Lime White Chocolate Cheesecake stands perfectly well on its own, pairing it with complementary items can elevate your dessert experience to new heights.
I recommend serving it with a dollop of freshly whipped cream to balance the tartness of the lime, or a scoop of vanilla bean ice cream for temperature contrast.
For drinks, try an espresso or French press coffee—the bitter notes work magic against the sweet-tart cheesecake.
Or maybe a chilled dessert wine? Moscato d’Asti, with its gentle bubbles, cuts through the richness beautifully.
Who needs a fancy restaurant when you’ve got this setup?
