Mega Blackberry Coffeehouse Muffins
Ingredients for Streusel Topping:
1 tablespoon unsalted butter
Ingredients for Muffin Batter:
1/2 cup unsalted butter, melted
1 tablespoon finely minced orange zest
1 cup buttermilk
2 teaspoons baking powder
1/2 teaspoon baking soda
1/8 teaspoon salt
In a separate bowl, stir together flour, baking powder, baking soda, salt, and cinnamon. Gently fold into batter. Once partially blended, fold in fruit. The use of semi-frozen fruit will help "firmup" the batter. If batter seems too loose, add a few tablespoons of flour (no more than 4 tablespoons) to make batter a bit stiffer.
Distribute batter evenly between the twelve cups, sprinkle streusel topping evenly over each muffin.
