Ingredients

The following ingredients have 4 Servings
  • 1 ¼ cups creamy peanut butter ((250g))
  • ½ cup granulated sugar ((100g))
  • ½ cup light brown sugar (firmly packed (100g))
  • ½ cup vegetable or canola oil ((118ml))
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 1 cup buttermilk ((236ml¹))
  • 2 cups all-purpose flour ((250g))
  • 1 Tablespoon baking powder
  • 1 teaspoon salt
  • 2 cups semisweet or milk chocolate chips
  • Additional granulated sugar for sprinkling on top (optional)

Instruction

  • Preheat oven to 375F (190C) and line muffin tin with paper liners (out of paper liners? See my tutorial on how to make the muffin liners seen in the photos above).
  • Combine peanut butter sugar, oil, and peanut butter and stir well to combine. Beat in eggs, then stir in milk and vanilla extract.
  • In a separate bowl, whisk together flour, baking powder, and salt.
  • Gently combine wet and dry ingredients with spatula.
  • Stir in chocolate chips when dry ingredients are halfway combined (don't over-mix the batter or muffins will be dense and dry).
  • Divide batter into muffin liners, filling each cavity ¾ the way full (keep in mind this recipe makes 18 muffins, so you will need two tins. If you only have one, bake the first batch and cover the remaining batter until the first batch has baked and mostly cooled). If desired, sprinkle muffins with additional granulated sugar.
  • Bake on 375F (190C) for 20-22 mins or until a toothpick inserted in the center comes out clean (avoid chocolate chips) or with moist crumbs. Do not over-bake or they will be dry.
