Step 1

Preheat oven to 350 degrees. Coat a 9x13-inch baking dish with nonstick cooking spray and set aside.

Step 2

In a large bowl, beat butter, sugar, brown sugar, vanilla, and molasses on medium speed until creamy.

Step 3

Add the egg and stir until completely incorporated. Add baking soda, flour, spices, and salt and mix until well combined. Spread dough into prepared pan, using clean hands or a rubber spatula to press the dough to the edges of the pan. Bake for 15-20 minutes; do not overbake! Cool in a pan with a wire rack.

Step 4

When bars have cooled, frost with cream cheese frosting or dust lightly with powdered sugar. They are delicious with nothing on them! Cut into squares and serve.

Step 5

For the frosting: Cream together the butter and cream cheese. Add the powdered sugar and vanilla. Slowly mix on low and then beat it on high until fluffy.
