Mrs Booth's Crumbly Crunchies

My sister and I both have fond memories of these biscuits, we always knew as 'crumbly crunchies', that our childhood friends' Mum used to make. These are much like melting moments, but a little lighter and not sickly sweet like melting moments can sometimes be. It had been over 20 years since I had tasted one of these, until I was lucky enough to get the recipe last night. Today I converted the recipe for the Thermomix and they turned out just as I remembered them. Depending on the size you roll them, this should make around 55 individual biscuits, which you then sandwich together.
