Preheat the oven @ 180 deg C. Prepare a tin by greasing it with butter. Sieve together flour, sugar, baking powder, baking soda, cocoa powder and salt together. Combine condensed milk, essence, vinegar and melted butter together, except water
Mix the sieved flour mixture with the wet ingredients, adding ice cold water little at a time and mixing it without any lumps.
Pour the mixed batter into the prepared tin and bake at 180C for about 30 – 40 minutes or until a toothpick inserted in the centre comes out clean.
Remove and cool in the pan for 10 minutes before cutting into equal squares and enjoy with evening tea. It freezes very well and a great snack for the kids for their break time. It tasted just right both chewy and sticky.
Note: It took me 40 min to get done. I left it inside the oven after switching off for another 10 mins. I let it cool completely before shoving it in the refrigerator for 1 hour before slicing them. It was a breeze.
Bon Appetit !!!
