Pumpkin Carrot Bars with Orange Icing

I can't wait for every October for two reasons: 1) Halloween is one of my favorite holidays, 2) I can't wait to make these sweet treats!

2 cups of flour
2 tsp baking powder
1 tsp orange zest
1/2 tsp baking soda
1/4 tsp salt
3 eggs, beaten
1 1/2 cups brown sugar
1 cup canned pumpkin
2/3 cup vegetable oil
1/4 cup milk
1 teaspoon vanilla extract
1 cup finely shredded carrots (about 1-2 large carrots)
1 cup walnuts or pecans, chopped
1 1/2 cups powdered sugar
1 -2 Tbsp orange juice
walnut or pecan halves

Preheat oven to 350 degrees F. Grease a 15x10x1-inch baking pan; set aside.

In a large mixing bowl stir together the flour, baking powder, orange peel, baking soda, and salt. Set the flour mixture aside.

In a medium bowl combine eggs and brown sugar. Stir in pumpkin, oil, milk, and vanilla. Then stir in carrots and chopped nuts. Add egg mixture to flour mixture, stirring with a wooden spoon until combined. Spread batter into the prepared pan.

Bake for 20 to 25 minutes or until a wooden toothpick inserted near the center comes out clean. Cool in pan on a wire rack.

For Orange Icing:
In a mixing bowl combine powdered sugar and enough orange juice to make an icing that is easy to drizzle.

Spread with icing; cut into triangles or bars. Top each piece with a walnut or pecan half.
