Ingredients

The following ingredients have 14 Servings
  • 3 cups all-purpose flour (, careful not to over measure, 375g)
  • 1 tablespoon baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/2 cup oil (, canola or vegetable)
  • 3/4 cup granulated sugar
  • 1/2 cup packed brown sugar
  • 1 tablespoon vanilla
  • 2 large eggs (, room temperature)
  • 1/3 cup sour cream (, room temperature)
  • 3/4 cup buttermilk (, room temperature)
  • 2 tablespoons instant coffee powder
  • 1 and 1/4 cups chocolate chips

Instruction

  • Preheat the oven to 425F degrees. Line a muffin pan with muffin papers, or grease and flour each cavity. You'll end up with about 14-15 muffins total.
  • In a large bowl whisk together the flour, baking powder, baking soda & salt. Set aside.
  • In a separate large bowl beat the oil and sugars together using an electric mixer. Add in vanilla & eggs and continue beating until well combined. 
  • In a liquid measuring cup or small bowl, mix together the sour cream, buttermilk and instant coffee powder. If it doesn't completely dissolve, that's ok.
  • With the mixer on low speed, beat in about 1/2 the flour mixture followed by 1/2 of the buttermilk mixture. 
  • Turn off the mixer and fold in the rest of the flour, buttermilk and chocolate chips using a large wooden spoon or rubber spatula. Be very careful not to over mix your batter. Having a few lumps is ok.
  • Spoon the batter into your prepared muffin pan, filling each to the very top. You should end up with about 14 -15 muffins.
  • Bake in the preheated oven at 425F degrees for 5 minutes. Then, without taking the muffins out of the oven, turn the oven down to 375F degrees and continue baking for about 12-15 minutes, or until an inserted toothpick comes out clean or with a few moist crumbs.
  • Allow the muffins to cool in their pan for about 5 minutes before taking them out of the pan and continue to cool on a wire rake
