Step-by-Step Instructions
- In a medium bowl, melt 4 tablespoons of unsalted butter. Mix in ½ cup of graham cracker crumbs and 2 tablespoons of sugar with a fork until the mixture resembles wet sand. Refrigerate to firm up while you prepare the muffins.
- Preheat your oven to 425°F (218°C) and line a 12-cup muffin tin with paper liners.
- In a large mixing bowl, whisk together 1 ½ cups of all-purpose flour, ⅓ cup of cocoa powder, ¾ cup of sugar, 2 teaspoons of baking powder, ½ teaspoon of baking soda, ½ teaspoon of kosher salt, and 1 cup of semi-sweet chocolate chunks.
- In another bowl, melt 4 ounces of chocolate along with the melted butter from the streusel. Stir in ⅓ cup of vegetable oil, 1 cup of whole milk, ½ cup of Greek yogurt, 2 large eggs, and 2 teaspoons of vanilla extract. Whisk until smooth.
- Carefully fold the dry ingredients into the wet mixture using a spatula. Mix until just combined.
- Fill each muffin well to the top. Press a few extra chocolate chunks and mini marshmallows into the batter, followed by a generous sprinkle of the chilled graham cracker streusel.
- Place the muffin tin in the preheated oven at 425°F and bake for 7 minutes. Lower the temperature to 350°F (177°C) and continue baking for another 13 minutes or until muffins are domed and a toothpick inserted comes out clean.
- Once baked, remove the muffin tin from the oven and let it cool for 5-10 minutes. Transfer the muffins to a wire rack to cool completely.
