Yes! I LOVE making these as no bake bars! They do crumble a bit more when you cut into them, but they are so delicious. I recommend heat treating your flour before making them (this kills potentially harmful bacteria that can grow on the flour). To heat treat your flour, microwave more than the recipe calls for (around 1/4 cup- 1/3 cup more) it in a bowl or pour it on a baking tray and baking at 350°F for 5 minutes. Let the flour cool, then make the shortbread as instructed, press the dough into the pan and place it in the freezer for 10-15 minutes before topping with caramel.
