Ingredients
For the topping:
1/2 cup brown sugar, firmly packed
6 tablespoons all-purpose flour
1/4 cup unsalted butter, melted
1 teaspoon ground cinnamon
1/4 teaspoon ground nutmeg

For the batter:
1 large egg
1 cup brown sugar, firmly packed
1/4 cup unsalted butter, melted
3/4 cup sour cream
2 cups all purpose flour
1 teaspoon baking soda
1/4 teaspoon salt
1/4 teaspoon cinnamon
2 cups diced peaches or nectarines


Pre-heat oven to 350 degrees F. Grease and flour a 12 cup muffin tin or line with paper cups.
Make the topping: Combine the brown sugar, flour, melted butter in a small bowl and mix until crumbly. Set aside.
Beat the eggs in a large bowl, then add the brown sugar, melted butter and sour cream.
Sift in flour, soda, salt and ground cinnamon into another bowl. Pour it into the wet ingredients and mix just to combine. Fold in diced peaches gently.
Spoon into prepared muffin tin and sprinkle generously with topping.
Bake for 20 to 25 minutes, until lightly browned and firm to the touch.
