Sponge Layer Cake

While me and my little one went on an adventure trip in search of cream cheese, my husband waited for us till we were done at a bookstore and bought me a book with some nice cake recipes. In return for what he got me, I baked the very first recipe that he liked as per the first photo in the book. And did I achieve the same...? I indeed did..at least I think I did..

Ingredients:
Unsalted Butter - 3/4cup plus extra for greasing
Castor sugar - 1cup
Eggs - 3
Flour - 1 1/2cups
Baking Powder - 1tsp
Strawberry Jam/ Raspberry Jam - 3tbs
Icing sugar to sprinkle

Grease a 20cm cake pan. Cream the sugar and butter together for 5-6minutes till light pale yellow and fluffy. Add the eggs one by one and beat well after each addition. Sift the flour and baking powder and carefully add it to the creamed butter and sugar.  Fold the flour in using a spatula. Pour the mixture into the prepared cake tin and smooth with a spatula. Bake for 25-30minutes in a preheated at 325F/ 180C. Test the cake with a skewer and if it comes out clean, remove the cake from the oven and using a spatula loosen the sides of the cake from the edge and turn over to a rack to cool. Leave to cool completely and then halve the cake across. Sandwich the cake with the jam. Sprinkle icing sugar on top and serve.
