Caramel snickerdoodle bars

I was so incredibly excited to make these. The flavors were totally there and I definitely need to try this again. The dulce de leche just didn't set and made a complete mess. This was #2 of my absolute failures for the weekend. Someone else, please try these so I can have the courage to try again!

Serves 48

• 1 cup butter, softened

Preheat oven to 350 degrees. Grease a 9x13 inch baking sheet with cooking spray.

In a large bowl, beat butter and brown sugar until light and fluffy. Add in eggs and vanilla. Whisk in flour, baking powder and salt until blended. Pour into the prepared baking dish.
