Chocolate Chunk Buttermilk Cake

We had a lot of people in and out of our house this past week, and I think when your home is all a hustle and bustlin' (I'm an elderly woman) you should have cake to offer. Right? I want to be that lady who greets a visitor with, "hello can I get you a piece of chocolate cake and a nice cold glass of milk, wait, did you say no thank you, well here one is anyway..." and then I shove it in their face. That's probably what Ina would do. So I made cake.
I had leftover buttermilk, and after googling "chocolate buttermilk cake best ever" I found this recipe. Jack, my tiny assistant baker, was helping me when suddenly he asked if we could put chocolate chunks in the cake. My first response was no but then he said, "why not?" And I stared at him and couldn't think of one good reason why not. So we threw a bag of chocolate chunks into the cake, and it was the best idea my 5 year-old has ever had. Carson even said this is the best chocolate cake he's EVER had. It's ridiculously moist, and the chocolate chunks add a fudgy texture that takes the cake to a whole new level. And then of course I used my favorite frosting ever, found here.
Please come over so I can shove this in your face because otherwise I WILL slowly finish it all.

All that's left anyway...
