1. Preheat the oven to 375 degrees. Line a 9×13 pan with parchment or grease with cooking spray. Set aside.
2. Whisk together the flour, baking soda, baking powder, and salt in a small bowl. Set aside.
3. Combine the butter, oil, and both sugars in a mixing bowl. Whisk or beat with the paddle attachment of an electric mixer until fully combined. Stir in the sour cream, egg, and extracts.
4. Fold in the dry ingredients until just combined. Transfer to your prepared pan.
5. Spray your hands with cooking spray and gently press the dough into the pan to create an even layer.
6. Bake 13 to 15 minutes, or until the edges are very lightly browned and the center is set. Be careful not to over bake.
7. Allow the bars to cool completely. Spread with frosting and sprinkles.
For the frosting:
1. Gently whisk the butter with an electric or hand held mixer. Add the powdered sugar, vanilla, and milk/cream.
