Gluten free millionaire's shortbread

The lovely peeps at Tala liked what I did with their cake stand and bun tray and asked if there was something else I would like to review. I chose a traditional design Tala-embossed swiss roll tin that is made in England -(40 x 28 x 2.5cm). The reason I chose the swiss roll tin is that I don't own anything like it and I was missing out on making tray bakes! With my lovely new swiss roll tin I decided to make a fabulously sweet gluten-free millionaire's shortbread, which consists of a crunchy shortbread base, a gooey caramel center and a top layer of crisp chocolate. Also known as a caramel shortcake, caramel squares or caramel slice.

  1. Preheat oven to 180C (160c fan) / 355F

  2. Lightly grease a swiss roll tin

  3. Mix the flour, xantham gum and sugar in a bowl

  4. Rub in the butter till the mixture looks like fine breadcrumbs

  5. Knead the mixture till you have a ball of dough

  6. Press the dough into the prepared tin till you have a flat even surface

  7. Lightly prick the top of the shortbread

  8. Bake for about 20 mins until firm to the touch and lightly browned

  9. Leave in tin to cool
