Old Fashioned Prunes Bolu

Mix eggs + granulated sugar at high speed, for 15 minutes/until thick.

Lower the mixer speed, then gradually add the flour mixture + cornstarch flour + sifted milk powder.

Finally add the butter liquid, mix until smooth. Turn off the mixer then stir again using a spatula, just to check whether there are butter deposits at the bottom.

Pour the mixture into a 22x22 sized cake pan, which has been greased with butter, then grease the bottom with baking paper again with butter. Then oven at 180 for 30-35 minutes, direct fire up and down.

For the first 10 minutes, take out the dough, put the prunes on top, then bake again until cooked.
