Banana Walnut Muffins

INGREDIENTS:
3/4 cup sugar
1-1/2 teaspoons cinnamon
1-1/3 cups flour 2 teaspoons baking powder
1/2 teaspoon salt
1/2 cup chopped walnuts
1/3 cup golden raisins
1 cup mashed banana (1 to 2 bananas)
1 cup whole milk yogurt
1 large egg
4 tablespoons unsalted butter, melted, or vegetable oil

DIRECTIONS:
Preheat the oven to 375°. Line a 12-cup muffin pan with baking liners. In a small bowl, mix 1/4 cup sugar with 1 teaspoon cinnamon.

In a large bowl, whisk together the flour, remaining 1/2 cup sugar, baking powder, salt, remaining 1/2 teaspoon cinnamon, walnuts and raisins.

In a small bowl, beat together the banana, yogurt and egg with a fork. Stir in the butter. Stir the wet ingredients into the flour mixture until just combined.

Fill the lined muffin cups with the batter. Sprinkle the reserved cinnamon-sugar mixture on top. Bake until golden and a toothpick inserted into the centers comes out dry, about 20 minutes.
