1 3⁄4 cups all-purpose flour
1⁄3 cup granulated sugar
2 teaspoons baking powder
1⁄4 teaspoon salt
1 beaten egg
3⁄4 cup apple cider or 3⁄4 cup apple juice
1⁄4 cup cooking oil
1⁄3 cup packed brown sugar (streusel)
3 tablespoons all-purpose flour (streusel)
2 teaspoons ground cinnamon (streusel)
3 tablespoons cold butter (streusel)
1. For streusel. Stir brown sugar, flour, and cinnamon in small bowl. Cut in butter with a pastry blender. Set aside.
2. For muffins. Lightly oil twelve 2 1/2-inch muffin cups or line with paper baking cups; set aside. In a medium mixing bowl stir together flour, granulated sugar, baking powder, and salt.
3. Make a well in the center. In a small mixing bowl combine egg, apple cider, and oil; add all at once to flour mixture. Stir just till moistened. (The batter should be lumpy.).
4. Spoon about 1 tablespoon of the batter into each prepared muffin cup. Sprinkle 1 teaspoon of the brown sugar mixture over each. Fill with remaining batter. Sprinkle tops of muffins with remaining streusel.
5. Bake in a preheated 400° F oven until golden brown, about 20 minutes. Remove muffins from pans; cool slightly on racks.
