Preheat oven to 350º
Grease and flour 3 8-inch round cake pans, or line with parchment paper, you can just put parchment on the bottom for easy cake release, set aside, see notes below if you only have 2 pans
beat the butter and sugar together with a mixer or stand mixer until light and fluffy
Beat in eggs, vanilla, and half the milk
mix the dry ingredients together in a separate bowl
stir half the flour into the wet ingredients
Add remaining milk, and beat until smooth
Then quickly beat in the remaining flour, until everything is fully incorporated and smooth
Divide batter evenly between prepared cake pans, 2 or 3 depending on what you have
Bake for about 25 minutes, until a toothpick inserted in the center, comes out clean
if you baked a double thick cake layer because you only had 2 pans bake that layer longer
Remove the cakes from oven when they're done
let cakes cool ten minutes, then loosen edges from pans, and turn onto a wire rack to finish cooling
When the cakes are cool, split one of the cakes if need be, set the cooled cakes to the side
Whip the cream, vanilla, and powdered sugar together until stiff peaks form
Beat in ricotta
stir in the mini chocolate chips
Place the bottom cake layer on the cake board or plate or cake stand, and spread about ⅔ cup of ricotta cream over the stop (about ¼ inch thick)
Place the second cake layer over the cream, and spread with another layer of ricotta cream
Repeat with 3rd layer
Spread the remaining ricotta cream over the sides of the cake, creating a semi-naked cake look
In a bowl set over a small pan of hot water, gently heat chocolate chips or semi-sweet chocolate and cream until chocolate chips are melted, or microwave in a microwave-safe bowl for 15-second intervals until chips are just melted
Stir mixture together
If the mixture is hot, let it cool until lukewarm, do not pour the hot ganache over the whipped cream and ricotta frosting, see notes below about drizzling the ganache
Spread chocolate ganache over the top of the cake, letting some drizzle down the sides
Refrigerate until ready to serve
