    Jaffa Shortbread Slice

    This delicious Jaffa shortbread slice is like a cross between a Jaffa cake and a chocolate caramel shortbread! 

    Jaffa Shortbread Slice - shortbread, orange jelly (jello) and chocolate layered together, easy to make and great for a quick treat

    My Jaffa shortbread slice is made up of a delicious layer of crumbly, buttery shortbread, topped with a layer of orange jelly, and then a thick layer of plain chocolate.

    Part Jaffa cake and part millionaire’s shortbread, with jelly instead of caramel, it is pretty easy to make and went down a treat with my family.

    I can’t blame them really, I may have nabbed a couple of slices that broke apart already….

    Chocolatey goodness set off by the tart jelly and crumbly shortbread – so delicious! 

    It’s a lovely weekend bake to make to enjoy with friends and family.

    The rustic look doesn’t matter too much when it is all about the flavour.

    If you like making more complex bakes with different layers like caramel shortbread then this is a bit simpler than that. Fun to make and to eat!

    Ingredients

    Here are the ingredients you will need for this recipe. For the quantities needed please refer to the recipe card further down the post. This is for your shopping list.

    • orange jelly packet
    • leaf gelatine – to make sure the jelly is not too soft
    • butter – I prefer to use unsalted
    • caster sugar
    • plain flour
    • plain/dark chocolate for topping

    Step by step instructions

    There are a few steps in this recipe, due to the layers you need to make. For the quantities of each ingredient required and the precise instructions please see the recipe card at the bottom of this post.

    1. First make up the jelly in a square baking tin. I added extra gelatine to the orange jelly pack to make sure the jelly was thick so it would stand up to being sliced. Refrigerate until set.
    2. Next bake your shortbread layer, in a square 9 inch baking tin. 
    3. Once it has cooled, cut the jelly to size (if different size) and place the jelly on top of the shortbread. This is quite tricky, be gentle and remember it will be covered with chocolate so you won’t be able to see any breaks!
    4. Finally, melt chocolate then pour it over the jelly and shortbread, still in the tin. Put in the fridge to set.
    5. Cut into squares with a sharp knife once completely set.

    Ingredients

    For the shortbread:

    • 150 g butter softened, I used unsalted
    • 60 g caster sugar (superfine sugar)
    • 160 g plain flour (all-purpose flour)

    For the jelly layer:

    • 1 packet of orange jelly (Jello) made up with the directed amount of water, I used Hartleys
    • 1 leaf of leaf gelatine

    For the chocolate layer:

    • 225 g plain chocolate
    UK Measurements – US Measurements

    Equipment

    9x9 silicone
    9×9 silicone
    jug
    jug

    Instructions 

    • First make the orange jelly to give it time to set. You might want to do this the day before. Make the jelly up as directed with boiling and cold water in a jug. To give a better set, I added additional gelatine. Soften 1 leaf of leaf gelatine in cold water, squeeze it out, then melt the leaf by heating on a low heat in small bursts in the microwave. Stir vigorously and add to the jelly in the jug. Mix well then pour the jelly into a shallow baking tray lined with clingfilm to set in the fridge. Leave for a few hours until set.
      1 packet of orange jelly (Jello), 1 leaf of leaf gelatine
    • To make the shortbread layer, leave the butter out until softened or warm up gently in the microwave. Then combine the caster sugar into the butter until soft and fluffy.
      150 g butter, 60 g caster sugar (superfine sugar)
    • Add the flour and mix well. Press into a ball with your hands.
      160 g plain flour (all-purpose flour)
    • Line a square pan (I used a silicone one, approx 9 inch square) with baking paper. Press the mixture into the pan with the back of your hand. Bake for 25-30 minutes at 180℃ / 350℉ until golden brown. Leave it to cool completely.
    • When cool, cut your jelly to size and place it on top of the shortbread layer. This is quite tricky to do and mine broke in places. As the jelly layer will be covered in chocolate it doesn’t really matter, just try to move it gently.
    • Break the plain chocolate into pieces and microwave in 30 second bursts on high, stirring in between, until fully melted. Allow it to cool a little then pour it on top of the jelly, spread it with the back of a spoon then put it back in the fridge to set.
      225 g plain chocolate
    • Use a hot knife to slice into pieces and serve.

      These look utterly gorgeous! Shortbread is so good and I bet it’s lovely combined with the chocolate orange flavour of a Jaffa cake.

      I do like the sound of this.and you avoid the problem of the chocolate slipping off the jelly that other bloggers have had with the small Jaffa cakes. Win win!

        Thanks Jacqui! The jelly was slipping all around but not like on the round Jaffa cakes I guess.
