Next up, we prepare the creamy lemon filling. In a large mixing bowl, beat the cream cheese and granulated sugar together with an electric mixer until smooth and creamy, usually around 2-3 minutes. Then, add the eggs, one at a time, mixing well after each addition. Once the eggs are blended in, add the vanilla extract, lemon zest, lemon juice, and cornstarch, mixing until everything is combined smoothly. The mixture should be luscious and fragrant, making it hard not to taste!
Now it’s time to pour that glorious filling over the baked crust. Carefully spoon the cheese mixture over the crust and smooth it out with a rubber spatula. Bake in the oven for 25-30 minutes until the edges are set but the center gives a little jiggle. Once done, let it cool to room temperature in the pan before transferring it to the refrigerator. I typically let it chill for at least 4 hours, though overnight is even better for that firm slice!
Finally, when the cheesecake bars have chilled and set, you can slice them into squares! I like to dust them lightly with powdered sugar and garnish with lemon slices or fresh berries for that extra pop of color. Enjoying these bars fresh out of the fridge when they are perfectly chilled is an absolute treat!
Pro Tips for Best Results
I’ve tested this recipe a few times, and I found that using room temperature cream cheese makes a world of difference in achieving that creamy texture. If you’re like me and sometimes forget to take it out early, feel free to microwave small chunks of cream cheese for 15 seconds to soften them up.
Also, make sure to zest the lemons before juicing! It’s easy to forget, but the zest is where a lot of that incredible lemon flavor comes from. I always use a microplane zester for fine zesting; it adds so much aroma to the filling!
Lastly, don’t skip the chilling time! I know it’s hard to wait, especially when you’re excited about tasting these bars, but allowing them to chill thoroughly will make slicing them cleanly and perfectly much easier. I learned this the hard way when I was too eager, and ended up with messy pieces everywhere!
Common Mistakes to Avoid
One common mistake I made the first few times was overbaking the bars. The center should be slightly jiggly when you take them out. If you let them bake until they’re firm, they can turn out dry instead of that delightful creamy texture we want. Just remember to trust your instincts; they might look a bit underbaked, but they will firm up as they cool. (See the next page below to continue…)
