These are a great snack - the frozen banana takes on the consistency of ice cream, you don't have to use a ton of nutella to get great taste and they are super fast. I like to grab a couple of these for a quick snack that doesn't make me feel too guilty.
Frozen Nutella Banana Bites
Slice banana and add about 1/8 to 1/4 teaspoon of nutella between banana slices. You may add toothpicks before putting the bites in the freezer, but it's whatever your preference is.
