Banana Chocolate Swirl Cupcakes

With the complete intention of coming directly home and studying for tomorrow’s midterm and preparing for my presentation so I would have some time to go running before dark, I somehow woke up on the couch with papers everywhere and Trader Joe’s Peanut Butter Puffins crumbs all over me…don’t judge me. Definitely needed a study break, and of course instead of running I chose to make these delicious banana chocolate swirl cupcakes! Now I reallllly need to go to the gym tomorrow. For the base I used Gina’s Banana Cupcake Recipe from the FoodNetwork, and came up with my own additions for the chocolate batter to swirl in. They take a little more patience than normal cupcakes do, but they look so pretty! Try them with this chocolate frosting recipe.
