  • cooking spray
  • 10 oz dark chocolate (85% cacao), broken into squares
  • 10 tbsp butter, cubed
  • 4 large eggs, room temperature
  • 3/4 cup sugar
  • 1 tsp vanilla extract
  • 1 cup all purpose flour
  • 1 cup milk chocolate chips, plus extra for the tops
  • 1 cup walnuts, chopped


  • Preheat oven to 350 degrees F. Line 11 muffin cups with foil liners and coat each with nonstick spray.
  • Melt dark chocolate and butter together in a large sauce pan (10-12") over very low heat. Stir continuously with a rubber spatula until smooth and fully incorporated. Remove from heat and let cool at least ten minutes.
  • Whisk eggs, sugar and vanilla together in a large bowl. Slowly add chocolate, whisking together with egg mixture. (Make sure chocolate is not too hot that it will cook your eggs.)
  • Gently fold in flour, just until incorporated. Add chocolate chips and nuts.
  • Fill prepared foil cups with batter as indicated in the post in order to get the height of these muffins. Top each muffin with additional milk chocolate chips. Bake 35 minutes or until muffin springs back to the touch. Let muffins cool in the pan on a rack for twenty minutes before trying to remove them. They are amazing warm, but are perfect when cooled.
  • Store in a tightly closed container for up to a week.


Using high quality butter, such as Kerrygold, and high quality chocolate, such as Guittard, really makes a difference in the taste of this recipe.
