Put all the ingredients except for the milk and jam into a food processor/mixer and blitz until smooth.
Add the milk slowly to make a soft dropping consistency.
If doing in the traditional way, cream the butter and sugar, and then the eggs one at a time adding a spoonful of flour each time and fold in the remainder of the flour& baking powder.
Add in the milk as above.
Spoon the mixture into cake cases.
Add a dollop (1/2 tsp) of jam on to each and use a cocktail stick to swirl through the cake mixture.
Bake for 15-20 minutes until cooked and golden.
Remove from the tin and cool on a wire rack.
Decorate with icing or just a sprinkling of icing sugar when they are cool.
