Ingredients
- 1 1/2 cups graham cracker crumbs
- 6 tbsp unsalted butter, melted
- 1/4 cup granulated sugar
- 16 oz cream cheese, softened
- 1 can (14 oz) sweetened condensed milk
- 1/2 cup key lime juice
- 1 tbsp lime zest
- 1 tsp vanilla extract
- for serving (optional) whipped cream
Instructions
- Step 1: Preheat your oven to 350°F. In a medium bowl, combine 1 1/2 cups graham cracker crumbs, 6 tbsp melted unsalted butter, and 1/4 cup granulated sugar. Stir until the mixture resembles wet sand.
- Step 2: Press the crumb mixture firmly into the bottom of a 9x9-inch baking pan to form an even crust. Bake for 8 minutes until golden and fragrant, then remove from oven and let cool.
- Step 3: In a large bowl, beat 16 oz softened cream cheese with an electric mixer on medium speed for 2 minutes until smooth and creamy.
- Step 4: Gradually add 1 can (14 oz) sweetened condensed milk while continuing to beat until fully incorporated.
- Step 5: Mix in 1/2 cup key lime juice, 1 tbsp lime zest, and 1 tsp vanilla extract. Beat on low speed until combined and the filling thickens slightly.
- Step 6: Pour the filling over the cooled crust and smooth the top with a spatula.
- Step 7: Refrigerate for at least 4 hours or until set firm.
- Step 8: Cut into bars and serve chilled, optionally topped with whipped cream.
