Nothing like a swirl: Chocolate Vanilla Marble Cake

Ok so I have this box of cocoa I bought a month ago, and I really wanted to use it, but I couldn't find a recipe that felt right, I was considering making cocoa rice krispies, but that would be a hard sell at my house, and nothing sells at home like coffee cake. Plus marble cake always has the added bonus of ending up with a great swirl on the inside, if by chance I get twirl just right, I think I did pretty good, I may have looked it up on youtube looking for a video that showed me how to do it, although I completely forgot to focus when it came down to doing it the way the video suggested.

I start off simple, with a box cake, I just made it to instruction. I always go the oil route rather than butter, I like the moisture level the oil brings.

I took half of the batter out, and added 1/3 cup cocoa.

I then oiled a bundt pan, I love the silicon kind, mainly because the cake just pops out. 

Place one layer of vanilla batter on the bottom. 

Then a layer of chocolate.

Then vanilla

Then more chocolate and then more vanilla, I like a lot of layers.

To swirl, you're supposed to make eights with a chop stick, bring up the chop stick at the end of the eight, I did do that, although I kept forgetting to bring up the chop stick, and just doing swirls. I did eventually manage to bring it up a couple times at the end.

Bake at 350 for around 50 minutes, until a knife comes out clean.

Once a little cooler I start peeling off the sides and squeezing the center to separate the cake from the sides of the pan.

Pretty even uncut.

Even nicer on the inside.
