These no‑bake Key lime cheesecake bars were inspired by a stash of small Key limes I found at the market. After hearing about the many memorable Key lime pies my parents sampled on a Florida road trip, I wanted to recreate that bright, tangy flavor in a dessert that’s easier to portion and serve than a whole pie.
Traditional Key Lime Pie
Classic Key lime pie uses fresh Key lime juice, sweetened condensed milk and egg yolks. For this version I wanted the same vibrant citrus character but in a more flexible, sliceable format. These bars are easy to cut, transport and portion — perfect for sharing with neighbors, friends, or a crowd.
Lime Varieties
Key limes are small, round and yellow‑green, with a floral, tangier profile than the larger Persian limes commonly found in supermarkets. They were widely grown in Florida until a hurricane in the 1920s devastated crops and led growers to replace them with hardier Persian varieties. Today Key limes remain prized for their unique aroma and acidity.
Easy No‑Bake Cheesecake
This no‑bake cheesecake method produces a creamy, mousse‑like filling without the risks of baking — no water baths, no cracked tops. Folding whipped cream into a rich cream cheese base lightens the texture while preserving the indulgent mouthfeel of cheesecake. The tartness of Key lime juice and the bright oil from zest keep the bars tasting fresh and lively.
Because the filling relies on whipped cream for volume, use full‑fat ingredients so the texture sets properly in the refrigerator. These bars will be lighter than a traditional baked cheesecake but still rich and satisfying.
Recipe Notes
Decoration tip: Sweetened whipped cream piped with a large French star tip makes an attractive finish. Portioning: Cut into squares or rectangles to suit your needs — this 9 x 9 pan easily yields 12–16 servings depending on how large you slice. Chilling time: These bars need to set in the fridge overnight; because they are no‑bake, they won’t be as firm as a baked cheesecake but will hold shape when chilled well.
📖 Recipe
No Bake Key Lime Cheesecake Bars
INGREDIENTS
Graham Cracker Crust
- 1 ½ cups (150g) graham cracker crumbs (about 10 full sheets)
- ¼ cup (23g) unsweetened shredded coconut
- 5 Tbsp (70g) butter, melted
Key Lime Cheesecake Filling
- 16 oz (550g) cream cheese
- ⅓ cup (75g) Greek yogurt
- 1 ¼ cups (156g) powdered sugar
- ⅓ cup (80 mL) Key lime juice (about 7 Key limes; yield may vary)
- 1 tablespoon Key lime zest
- 1 cup (250 mL) heavy cream (36% fat or more)
- 1 tsp (5 mL) vanilla extract
Decoration (Optional)
- ½ cup (125 mL) heavy cream
- 1 tablespoon granulated sugar
- 1 teaspoon vanilla extract
- 2 Key limes, thinly sliced
INSTRUCTIONS
Graham Cracker Crust
- Preheat oven to 350°F. (Baking the crust for about 12 minutes adds color and a slightly firmer texture; if you prefer truly no‑bake, chill the crust for at least 30 minutes instead.)
- Line a 9 x 9 metal pan with parchment paper, leaving an overhang on two sides.
- In a bowl, combine graham crumbs, shredded coconut and melted butter until evenly moistened. Press the mixture firmly and evenly into the bottom of the prepared pan.
- Bake the crust for 12 minutes, then remove and let cool.
Key Lime Cheesecake Filling
- In a stand mixer fitted with the paddle attachment, beat cream cheese until smooth and light. Add Greek yogurt and mix to combine.
- Add powdered sugar and mix slowly until incorporated, scraping the bowl as needed.
- Carefully add Key lime juice and mix on low to avoid splashing. Fold in lime zest with a spatula to distribute it evenly.
- Transfer the cream cheese mixture to a large bowl if needed.
- In a clean bowl with the whisk attachment, whip the heavy cream and vanilla on medium‑high until stiff peaks form.
- Gently fold the whipped cream into the cream cheese mixture until blended. Pour the filling over the cooled crust and smooth the top with an offset spatula. Cover loosely with foil (avoid letting foil touch the surface) and refrigerate overnight.
- When set, lift the dessert from the pan using the parchment overhang, place on a cutting board and slice into bars. Top with whipped cream and thin lime slices if desired.
Decoration (Optional)
- Whip ½ cup heavy cream with the sugar and vanilla until stiff peaks form. Transfer to a piping bag with a large French star tip and pipe a dollop or star on each bar.
- For a decorative lime twist, thinly slice cross‑sections of Key limes and cut three‑quarters of the way across each slice so you can twist one cut end away from the other, then place on the piped cream.
- Serve immediately after decorating.
