Self-frosting Nutella (or in our case Nutino) Cupcakes

These muffins are a nice treat and good to make when you get that bargain jar of chocolate spread.
I used my pretty, pretty tin for these.

1/4 cup butter, at room temperature
1/4 cup canola or mild vegetable oil
3/4 cup sugar
3 large eggs
1 tsp. vanilla
1 3/4 cup all-purpose flour
2 tsp. baking powder
1/4 tsp. salt
1/4-1/2 cup Nutella, at room temperature
Preheat the oven to 325F/ 170C
In a medium bowl, beat the butter, oil and sugar with an electric mixer until light and fluffy. Add the eggs and vanilla and beat until smooth.
In a small bowl, stir together the flour, baking powder and salt; add to the butter mixture and beat on low speed just until combined. The batter will be thick. It needs to be in order to swirl in the Nutella!

Divide the batter between 12 paper-lined muffin cups. Drop a spoonful of Nutella on top of each, and swirl through the batter with the tip of a bamboo skewer, knife or other pointy object. Bake for 25-30 minutes,  until springy to the touch. Tilt them in the pan to help them cool. Makes a dozen cupcakes.

I should have really put less mixture in my precious tin but I think they still look pretty fab. Thank you again for my tin Rachel.
