In search of marble cake

My little sister is one of the coolest people I know. And no, that's not sarcasm. I adore Darcy. I would do anything for her. In fact, I am. I told our mom that I would make her graduation cakes. I was thinking something simple like chocolate, white or yellow or even cupcakes. I asked Darcy what kind of cake she wanted the last time I was home. She thought about it for awhile and said "You know, I've always liked marble cake." Oh, boy. You see, I had never made a marble cake before. I didn't even have a recipe for marble cake. I told her that I would find a recipe for marble cake and give it a shot. My mom had two recipes which I made copies of. My grandma threw a curve ball into the mix by saying that my Great Grandma used to make a marble cake that was a mix of yellow, chocolate and spice cake. She couldn't find the recipe but I took Great Grandma's spice cake recipe. We'll see what happens. I also subscribe to Penzey's spice catalog (I've never ordered from them but I do like looking at the recipes... I told you that I have a problem!). The latest catalog had a recipe for marble cake. I made a marble cake from one of Mom's recipes for a pot luck at work. It was a tad dry. Tonight I made the marble cake from Penzey's. It wasn't dry but I still think it needs some work. Practice makes perfect and I really hope that my coworkers and Steve's like marble cake because they're going to be eating a lot of it in the next 5 months!
