Awesome Sour Cream Muffins - cooking recipe

Ingredients

MUFFINS
1 egg
1 cup sour cream
1 tablespoon soft butter
1/3 cup sugar
1 3/4 cups flour
1 teaspoon baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
BUTTER CRUMB TOPPING
3/4 cup flour
1/2 cup sugar
5 tablespoons room temperature butter

Preparation

Beat egg with a whisk in a large mixing bowl until light. Add Sour Cream, Butter, and Sugar; whisk together until smooth. Measure dry ingredients into a bowl or on waxed paper; add to wet ingredients and stir/fold until no more dry ingredients show. (over-mixing will make muffins tough).
Spray PAM lightly into 12 muffin cups, or use paper liners. Pour dough into each cup. Preheat oven to 400\u00b0F Mix crumb topping (if desired), until small crumbs form. Sprinkle evenly over each muffin.
Bake at 400 F for 20-25 minutes, until light golden brown and top is puffed. Remove from pan, serve immediately or let cool, place in closed container to be used later.
