Preheat oven to 300°F (150°C). Line muffin pan with liners
In a large bowl, cream butter and sugar. Mix in eggs, mashed bananas, cream, vanilla and cinnamon. Mix in salt, baking soda, and flour. Mix in nutella. Fill cupcake liners about 2/3 full
Bake for about 30 minutes, until a toothpick inserted in center comes out clean. (Baking time depends on the size of your muffins. Mine took about 40 minutes because my batter was really runny and my muffins were oversized.)
