Cake or muffins???

This is a recipe shared to me by a friend:

4 eggs

300 grams all purpose flour

200 grams sugar

Rind of one lemon or 1 ml vanilla extract

A pinch of salt

8 grams of baking powder

150 grams corn oil

150 grams milk

Mix above ingredients together. (It would be better if you use a Stand mixer).

Set aside 1/3 of the batter and add 15 grams of sifted dark chocolate powder. Mix well.

Prepare the muffin pans

Preheat oven at 180°/15-20 minutes

Fill each cup with the batter about 1/2 full + add the a spoonful of the chocolate batter in each cup + to create that particular swirl effect of a marble cake, use a toothpick

Bake at 180°/25 minutes

I was wondering what to make for some friends coming over for a potluck dinner and a dear friend (best friend) told me that it would probably be much better to prepare muffins instead of a cake. It would be easier for my friends to eat and to take it from the serving plate. Well, thanks to that spontaneous advice, I was able to make more than 20 muffins for 18 guests. A marble cake recipe turned into a muffin recipe. (Oh! To make more than 20 cupcakes I had to double the recipe above).

As for true friendships, i believe that it is a connection that can outlast time and space.
