We were all transfixed to The Great British Bake Off when Mary set them the challenge of making 12 Jaffa cakes. Whether it was making sure the cakes weren’t stuck to the tin or putting on the jelly the right way up, there were a lot of hurdles to overcome. I even tried them myself in a 90 minute time limit with varying degrees of success. But I’m giving it another go, this time without a 90 minute time limit but also making a giant version; this is my (edited) Giant Jaffa Cake recipe!
Mary’s recipe calls for a whisked sponge, which is practically impossible for me in my uni kitchen since I don’t even have an electric whisk! All of my bakes have been made completely by hand, from my Crystallised Stem Ginger Cookies to Red Velvet Hazelnut Biscotti. And while I’m happy to whisk up a 1 egg white meringue, I don’t fancy whisking 3 eggs with sugar by hand until the ribbon stage so I use a basic sponge recipe for this cake.
The relatively small amount of water used to make the jelly means it has a relatively firm set, ideal for slicing up when serving the cake as well as transferring on top of the cake. I didn’t get it dead centre the first time but I found that the set of the jelly meant it was fairly forgiving when it needed moving.
1 x 135g pack of orange jelly
200ml boiling water
125g granulated sugar
140g self raising flour
Zest and juice of 1/2 an orange
140g dark chocolate
2 tbsp runny honey
12 Jaffa cakes, halved
Line a 18cm sandwich tin with a few layers of clingfilm, making them as smooth as possible with some overhang.
Cut up the pack of jelly into cubes and place into a heatproof jug. Pour over the boiling water and stir until the jelly has dissolved. Place the sandwich tin into the fridge and then pour in the orange jelly and refrigerate for around 2 hours. When you are ready to bake, remove the tin from the fridge so the jelly comes to room temperature.
Preheat the oven to 170˚C. Grease and line the base of a 23cm springform tin.
In a bowl, cream together the margarine, the sugar and orange zest until it is light and fluffy. Add in the eggs one by one beating well between each addition, scraping down the sides of the bowl between mixing. Sift in the self raising flour and baking powder and using a spatula, fold in the dry ingredients until just incorporated. Lastly mix through the orange juice until the cake batter is smooth and even.
Transfer the mixture into the tin, using the back of the spatula to get the surface as level as possible. Bake the cake for around 20 minutes, or until the cake is golden brown, risen, springs back to the touch and an inserted cocktail stick comes out clean. Leave the cake to cool in the tin for 10 minutes before transferring to a wire rack to cool completely.
Once cool, level off the top of the cake using a serrated knife to get a smooth top. When the cake is cool and the jelly has set, flip the jelly onto the centre of the cake.
Prepare the chocolate glaze by breaking up the dark chocolate into a microwaveable bowl and add the margarine and honey. Microwave in 20 second intervals, stirring between each one until the chocolate glaze is smooth and very shiny. Leave to cool slightly for 5 minutes.
Now working quickly, use a palette knife to spread the glaze over the cake and jelly, covering the jelly and the visible top of the cake to get that distinctive Jaffa Cake shape. Then before the glaze sets, place the halved Jaffa cakes on top of the jelly, arranging them in an overlapping circle. Leave the glaze to set at room temperature.
