Cinnamon Apple Streusel Muffins

These are not quite as healthy as the other version, but they're quite tasty.

Cinnamon Apple Streusel Muffins
Topping
1/3 cup firmly packed brown sugar
3 Tbsp. flour
2 tsp. cinnamon
2 Tbsp. butter
Muffins
1 3/4 cup flour
1/3 cup sugar
2 tsp. baking powder
1/4 tsp. salt
1 egg, beaten
3/4 cup apple cider (I used fresh pressed apple juice.)
1 apple, peeled, cored and diced
1 tsp. vanilla
1/4 cup vegetable oil

Preheat oven to 400ºF. In small bowl, combine dry topping ingredients. Cut butter into mixture with fork. Set aside.

Line 12 muffin tins with paper cups. Mix flour, sugar, baking powder and salt. In separate bowl, combine egg, cider, apple, vanilla and oil. Add all at once to dry ingredients. Stir until just moist. Batter will be lumpy still. Spoon 1 Tbsp. batter into each muffin cup. Sprinkle with 1 tsp. topping. Fill with remaining batter. Sprinkle remaining topping on muffins. Bake 20 minutes. Makes 12 muffins.
