2. 2
   Sift flour and cornstarch 3 times into a bowl.
3. 3
   Beat eggs and granulated sugar in a medium bowl with an electric mixer on high speed for 8-10 mins, until a ribbon trail forms when beaters are lifted. Gently fold in flour mixture. Pour into prepared pan. Spread lightly.
4. 4
   Bake for 15-18 mins, until cake springs back when lightly touched. Turn out onto prepared rack to cool.

   For the ganache filling, combine ingredients in a heatproof bowl set over a pan of simmering water. Stir for 4-5 mins, until smooth. Remove bowl from heat. Cool slightly. Refrigerate for 30 mins, stirring occasionally with a wooden spoon, until thick and glossy. Using a serrated knife, slice sponge cake in half horizontally. Spread top of one cake half with ganache. Sandwich with remaining cake. Cut into 16 squares.
