I made another batch but added marshmallow half way through the baking. I am not a great fan of marshmallow but if you do you may want to, bake them in cuppies as it was really sticky and goey and I had a hard time cutting it.
What you need:
1 C nutella
3 large eggs
10T self-raising flour, sifted
What you do:
1. Mix eggs and nutella with a whisk or spatula till it well blended, it will look like a fudge
2. Add sifted flour and gently mix it till no lumps
3. Pour into a greased baking pan or cupcake casings and bake in a preheated oven at 160C to about 20-30mins or till skewer comes out clean
If you want to add marshmallow, when batter is still a bit jiggly, arrange them on top of the cake and continue with the baking.
