Apple Crumble Shortbread Bars

Hello everyone! Apple Crumble Shortbread Bars for you today. A buttery shortbread base topped with sweet spiced apples and an oat crumble topping. Perfectly buttery, sweet and spiced.

I have added a touch of cinnamon to the mixes but if its not your cup of tea you can leave it out. Make sure you let these bars cool 100% before cutting into them, this will give you a nice and clean cut. Serve warm with some caramel or ice cream for a delicious dessert or simple serve at room temperature.

  • Enjoy! I toped mine with top caramel when serving! Some ice cream would be delicious too!


  • These will last for 4+ days in an airtight container at room temperature.
  • Best eaten on day 1 & 2.
  • Please let your bars cool completely before cutting, this will give you a sharp cut.
  • I use a warm sharp knife to cut my bakes.
  • If you do not like cinnamon you can omit it.
  • Lovely served warm with some ice-cream and caramel sauce.
