Pre heat your oven to 180℃ or 350℉ and line your patty cake/cupcake pan with paper liners (I just use patty pan liners from the supermarket)
Place the caster sugar and room temperature butter in a large bowl
Using an electric hand mixer, beat on low speed until it starts to combine, then increase the speed to medium for about 2 minutes
Add the eggs and vanilla and mix again on low, then medium until well combined. Don't forget to scrape the sides of the bowl with a silicone spatula, to ensure everything mixes in well
Stop the mixer, then add ⅓ of the self-raising flour, then ⅓ of the milk, mixing on low. Continue adding in thirds until it's almost combined. Stop and finish mixing with you spatula to avoid over mixing the cake batter.
Use an ice cream scoop to scoop out the batter, popping it into the cupcake liners
Bake at 180 celsius or 350 fahrenheit for 15-18 minutes, until golden. Check the cakes with a cake skewer, then remove from the oven
Allow to cool in the tin, before transferring your patty cakes to a cooling rack
Once cooled, assemble with Chantilly Cream and jam
