The good thing about this cake is that to make the dough we will take a very short time. We will not need to mount the egg whites or beat the dough too much. With a simple rod or even with a wooden spoon we can make the mixture without complications.
Then we are going to put dehydrated dried fruit, specifically blueberries. If you do not have, you can replace them with raisins. In fact you can substitute this fruit for Chocolate chips, That I leave to your choice.
