Step 6: Bake for 12-15 minutes, until the outer edges of the crust have just begun to brown. It should not be fully cooked at this stage as it will cook further once the filling has been added. Remove and leave the oven on.

Step 7: Mix together all the ingredients for the filling until completely smooth and pour over the baked crust.

Tips for making the perfect lemon bars

Before you start preparing the shortcrust base of the lemon bars, remove the cream cheese from the refrigerator and let it sit out for at least 30 minutes before using it the filling. This makes sure that the cream cheese is easy to beat and won’t leave any lumps in your filling. 

One of the keys to getting perfect lemon bars is to make sure they cool completely before you decide to gobble them up. Let them cool enough that they are completely firm before eating. 

Storing the bars

Once the lemon bars have completely cooled, wrap them gently in plastic wrap so that they don’t dry out. They can be stored like this in the refrigerator for up to 4 days.
