The easiest ever Nutella Cake - This Nutella sponge cake is an easy to make marble loaf cake, topped with Nutella as frosting and roasted hazelnuts. A really simple and delicious chocolate and nut cake.
Remove about a third of the mixture into another bowl and add the 150g of Nutella. Gently stir in until combined. (If the room is cold, pop the Nutella in a bowl in the microwave for 15 - 20 seconds first to warm it and soften it slightly.)
Bake for about an hour or until a skewer comes out clean. This time may vary by up to 15 minutes either way depending on your oven so just check the cake at 45 minutes onwards.
