Keeping it simple will allow the lemon in this recipe to shine! You also don’t want to cook it all the way when your first bake it stand alone. Since we’ll be baking it a second time once the filling has been added a partial bake will ensure it doesn’t come out dry at the very end!
Don’t Skimp On The Lemon
You don’t want to get just a hint of lemon when you’re biting into a lemon bar. You want to be hit with it and to ensure that you need to use enough lemon.
To make sure you get the perfect sweet to sour ratio you using the lemon juice and zest is essential. The zest gives the bars a fresher taste and makes the lemon flavor pop. The cookie base and use of erythritol and stevia in the filling can be over powering so don’t be scared to use a little extra lemon in the filling.
