Step-by-Step Instructions
- Preheat your oven to 425°F (215°C) and prepare a muffin tin with paper liners.
- In a large bowl, whisk together all-purpose flour, granulated sugar, cornstarch, baking powder, baking soda, and salt until well combined.
- In a separate bowl, melt unsalted butter and mix with vegetable oil, egg, vanilla extract, and sour cream until smooth.
- Fold the wet mixture into the dry ingredients until just combined, then gently fold in white chocolate chips.
- Fill each muffin liner halfway, then create a divot for the Nutella in the center.
- Spoon Nutella into the divots, cover with remaining batter until about ¾ full.
- Drizzle leftover Nutella on top and swirl with a toothpick before baking.
- Bake for 8 to 9 minutes at 425°F (215°C) without opening the oven.
- Lower the oven temperature to 350°F (175°C) and bake for an additional 10 to 12 minutes.
- Cool in the tin for 5 to 10 minutes, then transfer to a wire rack to cool completely.

Notes
Mix just until combined to avoid dense muffins. Store in an airtight container at room temperature for freshness.
