For the bars

• Preheat the oven to 350 degrees. Prep a 8×8 or a 9×9 pan by lining with parchment paper and spraying with cooking spray. Set aside.
• In a microwave safe bowl, melt the butter.
• In a separate mixing bowl, whisk together the flour, corn starch, baking powder, nutmeg, cinnamon, and salt.
• In a medium sized bowl, use a hand mixer on medium speed to mix the melted butter and sugar until light and fluffy, about 3 minutes.
• Whisk in the egg and egg yolk for 30 seconds and then add the vanilla extract Whisk just until combined.
• With a rubber spatula, fold the and the chocolate chips into the wet ingredients. Just mix until there are no more signs of flour. Don’t over mix.
• Place the dough into the prepped pan and evenly distribute across the pan.
• Drop the Nutella by spoonfuls over the batter. Use a butter knife to swirl the Nutella through the batter.
• Bake for 25-28 minutes. Mine took exactly 25 minutes.
• When the bars are done, let them cool completely before cutting.
