Preheat the oven to fan assisted 160C / 180C/ 350F/ gas 4 and line and lightly oil two 9inch cake tins.
Add all the cake ingredients into a mixing bowl and whisk with an electric hand whisk until combined.
Split cake batter evenly between the two prepared tins and bake for 20-25 mins until a toothpick inserted comes out clean.
Let the cake cool completely on a wire rack.
Quickly warm the Nutella for about 30-45 sec in the microwave spread some on the base cake, sandwich the two cakes together and spread some more on the top.
