Pumpkin Dulce De Leche Greta Bar Cookies

1 stick unsalted butter, at room temperature, or slightly melted

¾ cup sugar 

¼ cup light brown sugar 

1 large egg

¼ cup vegetable oil

1 teaspoon vanilla extract

½ cup pumpkin 

1 ½ cups flour

1 teaspoon kosher salt

½ teaspoon baking soda

½ teaspoon cinnamon

2 tablespoons sugar

2 teaspoons cinnamon  

½ cup butterscotch chips, sauce, dulce de leche or bake club caramel (!!!)

Preheat the oven to 350 degrees. Grease an 8x8” square pan.

Combine the butter and sugars in a bowl until homogenous. Add the egg, oil and vanilla until it becomes one glossy batter. Stir in the pumpkin until well combined. 

Add the flour, salt and baking soda and ½ teaspoon cinnamon and mix until just combined. Spread the dough evenly in the pan, making sure it gets into the corners. 

In a small bowl mix the 2 tablespoons sugar, 2 teaspoons cinnamon together. Sprinkle the top of the batter with cinnamon sugar moisture. Scatter chips or caramel sauce over the surface. Using a butter knife, swirl these items with the batter.

Bake for 15-20 minutes, until the cookie slab has puffed and set, with light brown edges.  Cool completely in the pan before cutting into squares.
