The cake is all done in the baking pan, so there is no cleaning up! Just mix, bake and cool. The ganache makes it extra yummy.
Preheat oven to 350F.
Line the bottom of a 9-inch square cake pan with parchment paper and lightly grease with butter.
Measure all the dry ingredients into the pan and stir together to combine with a fork.
Make 3 holes in the dry ingredient and put the vanilla in one, vinegar in the 2nd and the oil into the third.
Pour the milk over it all and use a fork to stir to combine.
Place into the preheated oven and bake for 30-35 minutes or until a toothpick inserted in the center comes out clean. There may be a few moist crumbs and that is fine.
Remove and place onto a cooling rack until the cake has cooled then remove and place onto a cake plate.
Place the chocolate chips into a small pot.
In a second small saucepan heat the cream and butter. Do not boil. Just before the boiling point, pour over the chocolate chips. Let sit for about 2-3 minutes until the chocolate melts.Stir well to combine.
Let cool down then spread over the cooled cake.
