1/2cupchocolate chunks, or chips (semi sweet is best!) Plus more for garnish
4tbspunsalted butter, melted
4ozchocolate melted
1/2cupvegetable oil
1/2cupwhole milk, can sub for other milk
1/2cupgreek yogurt
2eggs, large
1tbspvanilla extract
1cupmini marshmallows, plus more for garnish
Instructions
In a small bowl, melt the 3 tbsp butter in the microwave for 30 seconds or until fully melted. Add the 3/4 cup graham crackers and 1 1/2 tbsp sugar. Mix to combine. The mixture should be like wet sand. Set in the refrigerator while you make the muffins.
Preheat the oven to 425° F. Spray a muffin tin with baking spray all over and then line with muffin liners.
Take out 2 medium sized bowls. In one bowl, add the 2 cups flour, 1/3 cup cocoa powder, 1/2 cup sugar, 2 tsp baking powder, 1/2 tsp baking soda, and 1/2 tsp kosher salt. Mix lightly with a whisk. Add the 1/2 cup chocolate chips and lightly mix to coat.
In the second bowl, add the 4 tbsp butter and 4 oz chocolate and microwave for 30 seconds at a time until fully melted. Mix well to melt all the chocolate.
Then add in the 1/2 cup vegetable oil, 1/2 cup milk, 1/2 cup greek yogurt, 2 eggs, and 1 tbsp vanilla extract. Mix well with the whisk. All at once, add the dry ingredients into the wet ingredients.
Add in the 1 cup mini marshmallows on top of the dry ingredients.
Using a large spatula, lightly and gently fold in the flour taking care not to over mix or mix too hard. You want the flour to JUST mix in till there are no mare large streaks. The batter will be lumpy.
Using an ice cream scoop for accuracy, scoop the batter into the prepared muffin tin all the way to the top.
Add a couple more chocolate chunks and more marshmallow to the top of each muffin.
Sprinkle the streusel generously over the tops.
Bake for 7 minutes on 425, then lower the temperature to 350°F and continue to bake for another 13minutes.
Take the muffins out and let them cool for 5-10 minutes in the tin, then using a knife or off set spatula remove and cool completely on a wire rack.
Notes
Spraying the tin and also using cups will help the muffins release. The marshmallows and the streusel will be sticky!
