Ingredients
- 1 1/2 cups graham cracker crumbs
- 6 tbsp unsalted butter, melted
- 16 oz cream cheese, softened
- 3/4 cup granulated sugar
- 1/2 cup sour cream
- 1/3 cup fresh key lime juice
- 1 tbsp key lime zest
- 2 large eggs
- 14 oz sweetened condensed milk
- 1 cup whipped cream
Instructions
- Step 1: Preheat oven to 350°F. In a medium bowl, combine 1 1/2 cups graham cracker crumbs and 6 tbsp melted unsalted butter, stirring until evenly moistened. Press the mixture firmly into the bottom of a 9x13-inch baking pan to form an even crust. Bake for 10 minutes until fragrant and golden, then remove and let cool.
- Step 2: In a large bowl, beat 16 oz softened cream cheese with 3/4 cup granulated sugar until smooth and creamy, about 3 minutes. Add 1/2 cup sour cream, 1/3 cup fresh key lime juice, 1 tbsp key lime zest, and 2 large eggs, one at a time, mixing well after each addition.
- Step 3: Slowly add 14 oz sweetened condensed milk to the cream cheese mixture, beating on low speed until just combined and smooth. Pour the filling evenly over the cooled crust, smoothing the top.
- Step 4: Bake the cheesecake layer at 350°F for 25-30 minutes until set but slightly jiggly in the center. Remove from oven and cool completely to room temperature, then refrigerate for at least 4 hours or overnight.
- Step 5: Once chilled, spread 1 cup whipped cream evenly over the top. Cut into 12 bars and serve chilled for a refreshing, tangy dessert.
