How to make
Beat eggs with the sugar until white. Gradually add the oil, sifted flour with baking powder and cola.
Finally, stir the mixture with a spoon with chopped walnuts and lemon zest.
Grease a cake form or tray. Pour 1/3 of the mixture, and top with 1/3 of the mixture which you've mixed into a solution with the milk.
Add the mocha coffee and pour in the last third of the mix. Put the cake with mocha and cola to bake in a preheated 360°F (180 °C) oven.
Leave the finished cake to cool and sprinkle it with powdered sugar if desired.
