Pre-heat oven to 350° (180°), grease and flour a 9 inch (22cm) cake pan or 9 1/2 inch (24cm) bundt pan.
In a large bowl beat the eggs, yolk and sugar until creamy and light about 3-5 minutes. Then add the vanilla and ricotta beat to combine.
In a medium bowl whisk together the flour, salt and baking powder. Add to the creamed mixture and mix just until combined (batter will be thick), fold in the mini chocolate chips*.
Spoon into the prepared cake pan and bake for approximately 30-40 minutes, test with a toothpick for doneness. Let cool completely, then remove from the pan and dust with powdered sugar before serving. Enjoy!
*Toss the chocolate chips with one teaspoon of flour before adding, this prevents the chips from sinking in the batter while baking.
