My first time that the cake surface doesn't break.
What you will need:
110 g plain flour
70 g melted butter
100 g sugar
1/2 tsp vanilla essence
1/2 cup raspberry (blend for about 2 sec)
Some icing sugar for dusting
Whisk eggs, sugar and vanilla essence till creamy. Fold in sifted flour and combine well. Lastly add in melted butter and mix well. Pour batter into a 20cm pan. Drop the chopped raspberry into batter and use a fork to mix well into batter (note that the raspberry will sink to the bottom, so avoid putting them in when pouring the batter) Bake at 180 deg C for about 30min.
