Cake tin: either 8 inch (20cm) square tin or 7 x 9 (18 x 23) rectangular tin
Instructions
Preheat your oven to 160 Fan / 180 C / 350 F / Gas 4 and grease and base line an 8 inch (20cm) square cake tin
In a small bowl or jug whisk together the milk and apple cider vinegar and set aside while you prepare the remaining ingredients
In a large bowl stir together the flour, sugar, baking soda and baking powder, mixing well
Once the milk has thickened slightly whisk in the oil and vanilla
Add the milk mixture to the bowl of dry ingredients and mix well, stirring up from the bottom of the bowl to make sure there are no flour 'pockets'
Pour the cake batter into the prepared tin, smooth and flatten the surface then bake for 25-30 minutes until risen and golden and a cocktail stick inserted in the centre of the cake comes out clean with no raw cake clinging to it
Leave to cool in the tin for 10-15 minutes before carefully lifting out onto a wire rack to cool completely
To make the vanilla buttercream beat together the butter, icing sugar, vanilla and cream until very pale and fluffy. Use softened butter if doing this by hand
If necessary, slice the domed top off the cake so the surface is flatter and more even
Spread the buttercream all over the top of the cake then decorate with fresh fruit, sprinkles, candles etc
Notes
Store the cake in an airtight container for 3-4 days
To freeze, wrap the undecorated cake tightly in foil or cling film then defrost thoroughly at room temperature before decorating
