This is one of my favourite retro treats! I have a weak spot for all lemon desserts actually.  I used to make this recipe in my food processor as it was much easier than making it by hand. Now that I have a Thermomix I no longer own a food processor and happily this slice even easier to make in the Thermomix.

Gluten-Free Lemon Delicious Slice

I have a friend who highly sensitive to gluten and is on a strictly Gluten-free diet.  He has a sweet tooth so I wanted to make a dessert that was safe for him to eat and super delicious! I trialled this recipe substituting White Wings Gluten-free flour with the regular flour.  The recipe was a straight swap between the flours and turned out perfectly. I couldn’t find any taste or texture difference between the two slices.

    Can this be frozen afterward?

      Hi Deanne
      I have never tried freezing the slice but I can’t see why it would be a problem.

    Hi Julie, I love your stuff and would like to do this for a bake sale instead of the standard and very sweet lemon coconut slice. Wondering how it would go out of fridge in Victoria atm? Fete goes from 4-8pm. Thanks

    1. Julie Carlyle says:

      Hi Nicole
      Thank you so much for your lovely comment. I don’t think this recipe would be suitable for a bake sales when the slice warms up it becomes more delicate.
      Sorry Julie
