Toffee Apple Cake Bars

If you are an apple dessert lover as I am, you will love these Toffee Apple Cake Bars ! And believe me, one bar just would not cut it.

Looking at the recipe it might look a little too much work. But the cake is mixed and baked, the Praline takes minutes to make (and set) and the Icing is done in a minute or two.

Sheet pan cakes are also one of my favorites and is perfect as a potluck dessert. You can either slice the cake beforehand, or when at the venue – easy peasy !

Slightly chewy, moist cake with Apple Icing and Walnut Praline is just heavenly and I am sure you and your family would love the cake as much as we do.

A few pieces of cake I had left kept well in a sealed container for 3 days, however the Walnut Praline did go soft.

  1. Pre-heat the oven to 180 deg C ( 350 deg F ) - Line a sheet pan, 24cm x 32cm ( 9 inch x 13 inch ) with baking paper (let the paper extend over the sides
  2. Sift Potato Flour, Brown Rice Flour, Bicarbonate of Soda and Brown Sugar into a medium mixing bowl
  3. Stir in the grated Apples, Eggs and Oil - mix well
  4. Pour batter into the lined sheet pan and bake 25 - 30 minutes or until a tester comes out clean - remove cake from the oven and let stand in the pan for 10 minutes
  5. Meanwhile make the Walnut Praline - Combine the Caster Sugar and Water in a small saucepan over low heat until the Sugar dissolves - bring to the boil uncovered without stirring - boil 5 - 10 minutes until the toffee is a caramel color - remove from heat - let bubbles subside
  6. Sprinkle the Nuts in a single layer on baking paper on a baking sheet - pour toffee mixture over the Nuts - let stand at room temperature until hardened - chop praline finely
  7. By now you can turn the cake out onto a wire rack - top-side up and let cool completely
  8. Apple Icing : Sift the Icing Sugar into a small mixing bowl - stir in just enough Apple Juice to make the Icing spreadable
  9. Once the Cake has cooled, spread with the Icing and sprinkle over the Praline
  10. Slice into bars and serve


  • I had a few bars left and it kept well at room temperature for 3 days (although the Praline had gone soft, more syrup like)
