Step-by-Step Instructions
Prepare the crust for key lime cheesecake bars
Preheat the oven to 350°F. Line a square baking pan with parchment paper, leaving extra paper on the sides so the bars are easy to lift out later.
In a mixing bowl, add graham cracker crumbs and sugar. Stir until combined. Pour in the melted butter and mix until all the crumbs are coated and look like wet sand.
Transfer the mixture into the prepared pan. Use the back of a spoon or the bottom of a glass to press the crust down firmly. Make sure the crust is packed evenly, including the corners, so it holds together after baking.
Bake the crust for 8 to 10 minutes. It should look slightly golden and set. Remove from the oven and let it cool completely before adding the filling.
Make the creamy cheesecake filling
In a large mixing bowl, add the softened cream cheese. Beat it until it is smooth and creamy with no lumps. This step is very important for a smooth cheesecake texture.
Add the sugar and mix again until well combined. Scrape down the sides of the bowl to make sure everything mixes evenly.
Add the eggs one at a time. Mix slowly after each egg just until combined. Do not overmix, as this can add too much air into the batter.
Next, add the sour cream, key lime juice, lime zest, and vanilla extract. Mix gently until the batter is smooth and creamy. The mixture should look thick but pourable.
Assemble the cheesecake bars
Pour the cheesecake filling over the cooled crust. Use a spatula to spread the batter evenly across the pan.
Tap the pan lightly on the counter to remove any air bubbles. This helps create a smooth top layer.
Bake the key lime cheesecake bars
Place the pan in the oven and bake for 30 to 35 minutes. The edges should look set, but the center should still have a slight jiggle when gently shaken.
Do not overbake, as this can make the cheesecake dry and cause cracks. The bars will continue to set as they cool.
Turn off the oven and let the bars sit inside with the door slightly open for a few minutes to help prevent cracking.
Cool and chill before slicing
Remove the pan from the oven and let it cool completely at room temperature. This may take about 1 hour.
Once cooled, place the pan in the refrigerator and chill for at least 3 hours or until fully set. Chilling helps the bars firm up and makes them easier to cut.
When ready to serve, lift the bars out using the parchment paper. Use a sharp knife to cut into squares. Wipe the knife between cuts for cleaner slices.
Tips for the Best Results
- Always use room temperature cream cheese for a smooth batter
- Mix gently after adding eggs to avoid too much air
- Do not skip pre-baking the crust
- Bake just until the center is slightly jiggly
- Chill long enough before cutting for neat slices
- Use a sharp knife and clean it between cuts
Variations or Add-ins
