Notes
Avoid overmixing the cake batter once you add in the flour. Doing this will cause it to become dense, and not have that light and fluffy texture you're looking for.
Remember to use room temperature eggs for this recipe. It will ensure the batter has an even consistency and cooks perfectly.
You can slice the cake loaf and enjoy it as-is, or top it with some sugar icing or just a light dusting of powdered sugar.
To make cleanup easier, you can line the loaf pan with parchment paper and leave a bit overhang from both the sides for you to easily pull up the cake.
The key to getting the perfect texture and flavor is to measure the ingredients accurately. Use measuring spoons and cups to get it right!
