Pumpkin Apple Streusel Muffins

2 ½ cups all-purpose flour

2 cups white sugar

1 tablespoon pumpkin pie spice

1 teaspoon baking soda

½ teaspoon salt

2 eggs, lightly beaten

1 cup canned pumpkin puree

½ cup vegetable oil

2 cups peeled, cored and chopped apple

2 tablespoons all-purpose flour

¼ cup white sugar

½ teaspoon ground cinnamon

4 teaspoons butter

Preheat oven to 350 degrees F (175 degrees C). Lightly grease 18 muffin cups or use paper liners.

In a large bowl, sift together 2 1/2 cups all-purpose flour, 2 cups sugar, pumpkin pie spice, baking soda and salt. In a separate bowl, mix together eggs, pumpkin and oil. Add pumpkin mixture to flour mixture; stirring just to moisten. Fold in apples. Spoon batter into prepared muffin cups.

In a small bowl, mix together 2 tablespoons flour, 1/4 cup sugar and 1/2 teaspoon cinnamon. Cut in butter until mixture resembles coarse crumbs. Sprinkle topping evenly over muffin batter.

Bake in preheated oven for 35 to 40 minutes, or until a toothpick inserted into a muffin comes out clean.
