FAQ
Q: Can I make no-bake lemon bars without condensed milk?
A: Yes! Substitute condensed milk with a mix of 1 cup cream cheese + ½ cup powdered sugar + ¼ cup sour cream. The bars will be slightly less sweet but equally creamy and tangy.
Q: How long do no-bake lemon bars need to chill?
A: A minimum of 4 hours is needed for the filling to set fully. For the cleanest, sharpest slices, chill overnight. Rushing the chill time results in a soft, runny filling.
Q: Can I use bottled lemon juice for these bars?
A: Fresh lemon juice is strongly recommended. Fresh juice delivers a brighter, more vibrant citrus flavor and natural acidity that helps the filling set properly. Bottled juice tends to taste flat.
Q: Why are my no-bake lemon bars not setting?
A: The most common reason is not enough chill time. Make sure to refrigerate for a full 4 hours minimum. Also ensure the lemon juice and condensed milk ratio is correct too much liquid prevents setting.
Q: Can I make no-bake lemon bars ahead of time?
A: Absolutely. These bars are perfect for making 1-2 days ahead. Store covered in the fridge and slice just before serving for the cleanest presentation.
