Banana Chocolate-Swirl Cupcakes

We have a new addition to our family of three (two humans and a dog) - a shiba inu puppy! Training our silly pooch was quite a tedious and challenging task when we first got her 3 years ago, and now that she's fully trained, I can't imagine having to go through the whole process with the new puppy again. Well, I guess I must be crazy! (Pictures of our dogs can be found here and here)
