Thermomix Lemingtons

Thermomix Lemingtons are my lemony version of the very popular Australian recipe for lamingtons (usually filled with jam and dipped into chocolate icing). I have already made and published an awesome recipe for Lamington Swiss Roll which you can find here. But this time I am taking it one step further and for my lemon version, my Aussie friend Arwen helped me come up with the name lemingtons. The tangy tartness of the lemon curd sandwiched between deliciously fluffy sponge cake squares, then dipped into lemony goodness and rolled in coconut will delight the whole family for a special treat.
