Steps for Preparing and Baking the Walnut and Chocolate Chip Loaf Cake:

• In a large bowl, combine the eggs with the granulated sugar. Using the electric mixer, beat the two ingredients until you get a frothy and almost white mixture. Add the milk (at room temperature) and the vegetable oil, and mix them into the egg and sugar mixture.

  Sift the all-purpose flour and baking powder, and gradually add them to the mixture, then also add the potato starch.

  Continue using the electric mixer until the batter is smooth and homogeneous.

• Place the walnuts on a cutting board and chop them into not too small pieces with a knife, set aside 4/5 tablespoons for decoration and add them to the mixture, also add the chocolate chips (set aside 3/4 tablespoons for decoration).

  With a spatula, fold in the walnuts and chocolate chips into the batter, using an upward motion.

  Grease and flour a loaf pan, or if using disposable aluminum pans, they do not need to be floured. Pour in the batter, level it with the back of a spoon, and top with the reserved walnuts and chocolate chips.

• Bake in a preheated oven at 356°F for about 40 minutes, always perform the toothpick test. If halfway through baking you see that the top starts to brown too much, cover it with a sheet of aluminum foil.

  Once baked, let the loaf cake cool and then sprinkle with powdered sugar.
