Ingredients
  

  • For the Streusel:
  • 3/4 cup all-purpose flour
  • 1/3 cup white sugar
  • 6 tbsp unsalted butter cold
  • For the Muffins:
  • 1/4 cup unsalted butter melted and cooled
  • 1/4 cup neutral oil
  • 2 large eggs room temperature
  • 1 cup buttermilk room temperature
  • 1 tbsp vanilla extract
  • 1 cup white sugar
  • 2 1/2 cups all-purpose flour
  • 2 1/2 tsp baking powder
  • 1 tsp baking soda
  • 1/4 tsp salt
  • 2 tsp cornstarch
  • 1 cup mini chocolate chips

Instructions
 

  • Preheat oven to 425°F and line a jumbo muffin tin with paper liners.
  • Make streusel by combining flour, sugar, and cold butter in a medium bowl. Mix with fingertips until crumbly. Refrigerate while preparing muffin batter.
  • In a large bowl, whisk together flour, baking powder, baking soda, salt, and cornstarch. Set aside.
  • In another large bowl, whisk together melted butter, oil, eggs, buttermilk, vanilla, and sugar until smooth and well combined.
  • Add dry ingredients to wet ingredients. Using a rubber spatula, fold together until just barely combined with a few flour streaks remaining.
  • Gently fold in mini chocolate chips with just a few strokes.
  • Divide batter evenly among muffin cups, filling each 3/4 full. Sprinkle chilled streusel generously over each muffin top.
  • Bake at 425°F for 5 minutes, then reduce temperature to 375°F without opening oven door. Continue baking 20-25 minutes until toothpick inserted in center comes out with a few moist crumbs.
  • Cool in pan for 5 minutes before transferring to wire rack.

Notes

Don't overmix the batter - a few flour streaks are perfect for fluffy muffins
Room temperature ingredients mix better and create better texture
Two-temperature baking creates the signature bakery-style dome tops
Make homemade buttermilk by mixing 1 cup milk with 1 tbsp lemon juice, let sit 10 minutes
Store covered at room temperature for 3 days or freeze individually wrapped for 3 months
Mini chocolate chips distribute better than regular-sized chips
Cornstarch is key for the tender, cake-like texture
