Upside down lemon slice

The perfect balance between sweet and citrus.

There are so many different versions out there for lemon slices, but this upside down version has just the right twist to make it extra special. The topping is made first and then set aside while you prepare and bake the base. After partially cooking, you take the base out of the oven and pour the lemon topping all over. The mixture seeps into the base creating the most moist and deliciously lemony flavour throughout so every bite is packed with a citrus burst. It’s the perfect slice for the summer season, with a refreshing sweet and sour kick. Dig in!
