A delicious low sugar version of jaffa cakes that tastes just like the real thing! :)
First, make the jelly (jello): Zest the oranges, and put the zest in a pan. Peel the oranges and discard peel, then blitz the peeled oranges in a food processor until smooth.
Take off the heat and whisk in 1-2 tsp of gelatin and the orange extract (if using), then pour into a cold dish and allow to cool completely before placing in the fridge to set properly.
Mix all of the ingredients in a bowl until it resembles a soft biscuit dough. If needed, add a little splash of milk to help it come together, but it should be able to come together without.
Roll the dough out on a floured surface to about 2cm (3/4") thick and cut out small circles with a 5cm (2") cookie cutter. Place on a lined baking tray (you may need two, or to cook in two batches).
Bake in the preheated oven for about 10-15 mins, or until cooked and just starting to go a little golden.
Allow the cakes to cool on a cooling rack. When they are cool, top each cake with about 1 heaped tsp of jelly (or cut out the set jelly with the same cutter as the biscuits - or better yet, a slightly smaller one if you have one), try to leave a thin outer rim of cake showing to get a more authentic look.
*I use Great Lakes gelatin, which you can get here
**rice syrup counts as a free sugar/added sugar, but is fructose-free so is better metabolised by the liver. And even using rice syrup and 85% dark chocolate, these jaffa cakes have less than 1/2 tsp sugar each!
