Preheat your oven to 180 degrees and grease and line a 20cm round cake tin with baking paper.
Put all ingredients into a large bowl and whisk until mixture is just smooth.
Add the chopped Snickers and carefully fold through.
Pour mixture into the cake tin and bake for approximately 40 minutes or until cake is cooked through when tested with a skewer.
You can top this cake with your favourite icing or ganache
