There are few better things that you can do with a little one than baking.
In my experience they love it. The youngest was so proud of her cake and loved telling her mum that she'd helped with it.
Also a raspberry cake like this is a great way of using up some of the raspberries!
Really easy recipe, just a standard sponge mix with 200g of raspberries added in at the end and a couple teaspoons of vanilla essence., tastes amazing though!
