Description

Indulge in a blissful slice of summer with this silky, tangy Key Lime Cheesecake. A perfect harmony of creamy cheesecake and bright citrus zest, all perched on a buttery graham cracker crust. Easy enough for any baker and unforgettable in flavor.


Ingredients

Crust

  • 1½ cups (180g) graham cracker crumbs (about 12 full-sheet graham crackers)

  • 5 Tbsp (71g) unsalted butter, melted

  • ¼ cup (50g) granulated sugar

Cheesecake Filling

  • 32 oz (904g) full‑fat brick cream cheese, softened

  • 1 cup + 2 Tbsp (225g) granulated sugar

  • ½ cup (120ml) key lime juice (fresh or bottled)

  • ⅓ cup (80g) sour cream or plain yogurt, at room temperature

  • 1 tsp pure vanilla extract

  • 2 tsp key lime zest

  • 3 large eggs, at room temperature

Optional Toppings

  • Homemade whipped cream

  • Fresh berries (raspberries, blueberries, strawberries)

  • Key lime or regular lime slices

  • Toasted coconut flakes (optional for a tropical touch)


Instructions

  1. Preheat & Prep: Preheat oven to 350 °F (177 °C). Arrange racks with a lower one for your water bath.

  2. Make Crust: Combine graham crumbs, sugar, and melted butter until sandy. Press into a 9-inch springform pan (bottom and slightly up the sides). Pre-bake 10 minutes, then cool slightly.

  3. Prepare Filling: Beat cream cheese and sugar until smooth (~2 minutes). Add lime juice, sour cream (or yogurt), vanilla, and zest; mix until combined. Add eggs one at a time on medium speed; mix just until blended.

  4. Bake with Steam Bath: Pour batter into crust. Place a large metal pan filled with ~1-inch boiling water on the lower oven rack. Position cheesecake on middle rack and close quickly.

  5. Bake: Bake for 55–70 minutes. The center should jiggle slightly when tapped.

  6. Cool Gradually: Turn oven off, crack the door, and let cheesecake cool inside for 1 hour.

  7. Chill: Remove and let reach room temperature. Refrigerate for at least 4 hours or overnight. Before serving, run a knife around the pan rim and remove.

 

For neat slices, wipe a warm knife between cuts. Top with whipped cream, berries, or lime slices if desired.

Notes

Room Temperature Ingredients: Ensure cream cheese and eggs are at room temperature to avoid lumps and over-mixing.

Water Bath Alternatives: Use the steam (no‑soak) bath method above or wrap the pan with foil and place in a roasting pan with hot water (traditional method).

Substitutions: Use 200g digestive biscuit crumbs (plus a bit more sugar) if graham crackers are unavailable. Greek yogurt works in place of sour cream.

Make-Ahead & Freezing: Cheesecake can be made ahead, chilled overnight, or frozen for up to 3 months (ensure it’s tightly wrapped).

Crack Prevention: Avoid over-mixing, maintain consistent oven temperature, and cool slowly.
