I really like this superb lemon filling recipe for cakes, cupcakes, and muffins!! It is from Wilton, the company that makes all the great  baking accessories!  

It is not overly sweet and it has a strong lemony taste.   No need for lemon extract!  

I like cooking the lemon peel with the filling rather than adding it at the end because it softens the peel.  

Use a fine sieve to strain your lemon juice.  

DO NOT use this recipe  for pies and tarts!!  They need a sturdy lemon filling with different ratios of ingredients.

BEST TIP: Using fresh lemons for the juice and zest makes all the difference in the world!   It is SO worth the extra effort!
