Ingredients

Muffins:

  • 1 cup all-purpose flour
  • 1/2 cup baking cocoa powder
  • 2 1/2 teaspoons baking powder
  • 1/2 teaspoon salt
  • 1/2 cup canola oil
  • 1/4 cup milk (2% or higher)
  • 1/2 cup granulated sugar
  • 1/4 cup brown sugar
  • 1 teaspoon vanilla
  • 1 large egg
  • 1 cup grated zucchini
  • 1/2 cup semi-sweet mini chocolate chips

Graham Cracker Streusel:

  • 1/2 cup all-purpose flour
  • 1/2 cup packed brown sugar
  • 1/2 cup graham cracker crumbs
  • 6 tablespoons butter , melted
  • 3/4 cup semi-sweet chocolate chips
  • 60 mini marshmallows

Instructions

  • In a small bowl, combine the flour, cocoa, baking powder and salt. Set aside.
  • In another bowl, mix together the oil, milk, sugars, vanilla, egg and zucchini until well combined. Add in the dry ingredients and mix just until combined. Don't overmix, or your muffins will be tough! Fold in the mini chocolate chips.
  • For the streusel, combine the flour, sugar, butter, and graham cracker crumbs in a small bowl until well mixed and crumbly.
  • Spray a jumbo muffin pan with cooking spray. Using an ice cream scoop, put one scoop of batter into each of the cups. Put a tablespoon of streusel, 10 marshmallows, and a sprinkle of chocolate chips over top the batter in each cup. Scoop the rest of the batter evenly over the 6 muffin cups. Batter will be almost to the top of each cup. Sprinkle the remaining streusel and mini chocolate chips over the batter of each of the cupcakes.
  • Bake at 425 for 5 minutes, then reduce the temperature to 375 and bake for another 20 minutes. Do not open the oven ...just reduce the temperature. A toothpick inserted into the center of a muffin should come out clean. Because of the chocolate in the middle, the toothpick might have a little chocolate on it, but there should not be uncooked batter on it.
  • Store in an airtight container. These muffins keep for up to 5 days at room temperature.

Notes

If you don't have a jumbo muffin tin, you can use a regular muffin tin and get 12 muffins. Reduce the baking time so they do not over bake.
