In a bowl, crack the eggs and add the sugar. Use an electric whisk to mix everything together. Gradually add the milk, oil, lemon zest, and finally the flour and baking powder, continuing to mix until the batter is smooth and homogeneous.

If you want to add the apples at the moment, there's no need to coat them with lemon. I cut them fresh and added them directly to the batter. Once all the ingredients are added, mix again until everything is incorporated.

Once done, take a 10-inch springform pan (other shapes and sizes will work too), line it with parchment paper, pour in the batter, and then add the toasted and chopped walnuts and almonds as desired.

Bake in a preheated oven at 350°F (180°C) for about 40 minutes.

Once ready, decorate with powdered sugar.

Oh, it's so good, it melts in your mouth.
