Pumpkin Apple Streusel Muffins

Ingredients:
2 1/2 cups all-purpose flour
2 cups white sugar
1 tablespoon pumpkin pie spice
1 teaspoon baking soda
1/2 teaspoon salt
2 eggs, lightly beaten
1 cup canned pumpkin puree
1/2 cup vegetable oil
2 cups peeled, cored and chopped apple

Topping:
2 tablespoons all-purpose flour
1/4 cup white sugar
1/2 teaspoon ground cinnamon
4 teaspoons butter

Directions:
1. Preheat oven to 350 degrees F. Lightly grease 18 muffin cups or use paper liners.
2. In a large bowl, sift together the flour, 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.
3. 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.
4. Bake in preheated oven for 35 to 40 minutes, or until a toothpick inserted into a muffin comes out clean.

Review:
Very moist, sweet, and the flavors combined are perfect. Also, if you do not have the 1 Tbs. pumpkin pie spice, substitute: 1 1/2 t. cinnamon, 3/4 t. ginger, scant 1/2 t. allspice, scant 1/2 t. nutmeg. The streusel topping didn't work perfectly for me, it became too warm by the time I needed to put it on the top. So instead I just crumbled the sugar mixture on the top and when the muffins came out the crumble melted on top and came out with this yummy cinnamon crunch top.
