A traditional US treat, s’mores are a combination of biscuit, chocolate and marshmallow – let’s make some!


  • You will need 4 consol jars or large jam jars for this recipe.


  • 1 packet digestive biscuits
  • 4 tablespoons butter, melted
  • Cake
  • 1 1/8 cups cake flour
  • ¼ cup cocoa powder
  • 1 teaspoon baking soda
  • ¼ teaspoon salt
  • ¾ cup brown sugar
  • 1 egg
  • 1 teaspoon vanilla extract or essence
  • ½ cup milk
  • ½ heaped cup of full cream plain yoghurt
  • ½ cup sunflower oil (or you can use melted butter)


  • 2 bags marshmallows


  1. Crush the biscuits in a Ziploc bag with a rolling pin or your fingers
  2. Mix the biscuit crumbs with the melted butter and once well mixed through, divide the mixture into 4 parts and press into the base of each jar.
  3. Now add all the cake ingredients together in one bowl and mix for 1-2 minutes until everything is well blended.
  4. Using a ¼ cup measure, scoop the batter into the jars until about ½ way up the jar. (you can eat any leftover mixture yummy!!)
  5. Now listen up – put the jars into a square baking dish / tin and put 2 cups of warm water into the tin (not each jar!) – this will help to cook the cake. Bake for 35-40 minutes or until a toothpick inserted into the centre comes out clean.
  6. Take the jars out the oven, and put as many marshmallows you can possibly put into the top of each jar.
  7. Put the jars back into the oven and grill the marshmallows until they are nicely browned. Serve and enjoy!!
