Preparation Steps

• Preheat oven to 350°F (175°C). Grease and flour an 8x8 inch baking pan.
• In a medium saucepan, melt the butter over low heat. Remove from heat and stir in the Nutella until smooth.
• Whisk in the eggs one at a time, then stir in the vanilla extract.
• In a separate bowl, whisk together the flour, baking powder, and salt.
• Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
• Fold in the chocolate chips, if using.
• Pour the batter into the prepared baking pan and spread evenly.
• Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with moist crumbs (not wet batter).
• Let cool in the pan before cutting into squares.
