  • 3 cups all-purpose flour, spooned & leveled (375g)
  • 1 cup granulated sugar (200g)
  • 1 Tablespoon baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • 2 cups semisweet chocolate chips
  • 2 large eggs, room temperature
  • 1 cup buttermilk or milk, room temperature (240ml)
  • ¼ cup salted butter, melted
  • ¼ cup vegetable oil
  • 2 teaspoons vanilla extract
  • Coarse sugar, for sprinkling


  • Preheat oven to 425°F. Spray a 6-cup jumbo-size muffin tray with baking spray or line with paper liners. Set aside.
  • In a large bowl, whisk together the flour, sugar, baking powder, baking soda and salt. Add chocolate chips and stir to evenly distribute.
  • In a separate bowl, combine the eggs, buttermilk, melted butter, oil, and vanilla.  Whisk well, then add to the flour mixture, stirring by hand with a wooden spoon or rubber spatula just until combined. It's okay if the batter is lumpy and thick. Do not overmix.
  • Divide the batter between the muffin cups, filling them to the top. Sprinkle with coarse sugar. Bake at 425°F for 5 minutes, then decrease the oven temperature to 350°F without opening the oven door and continue to bake for 24-26 minutes until a toothpick inserted into the center of a muffin comes out clean. Do not overbake.  
  • Cool for 5-10 minutes in the pan, then turn out onto a wire cooling rack.



  • Storage: Once the muffins have cooled completely, store in an airtight container on the counter for up to 5 days or in the fridge for 1 week.
  • Freezing: These muffins freeze well for up to 3 months. Thaw on the counter before serving.
  • Serving size: The nutrition is calculated using an online tool for one whole jumbo-sized muffin. Regular sized muffins will have half the calories.
  • Buttermilk: Whole milk may be used instead of buttermilk. Or for a buttermilk substitute, just add 1 Tablespoon of lemon juice or vinegar to a 1 cup measuring cup and fill it the rest of the way with milk. Let this sit for 5 minutes before using in the recipe in place of the buttermilk.
  • Regular and Mini Size Muffins: For regular muffins, bake for 5 minutes at 425°F, then reduce oven temperature to 350°F degrees and continue to bake for 12-14 minutes. Makes 14-16 muffins. For mini muffins, bake at 350°F for 11-13 minutes. Makes about 35-40 mini muffins.
