Butterscotch Oatmeal Bars

Begin by preheating your oven to a medium-high temperature of 350 degrees Fahrenheit, equivalent to 175 degrees Celsius. Next, lightly coat a 9x13-inch baking pan with a thin layer of oil or cooking spray.

In a separate bowl, combine the dry ingredients - 2 cups all-purpose flour, 1 teaspoon baking powder, 1/2 teaspoon baking soda, and a pinch of salt - and whisk them together until well incorporated.

Meanwhile, in a large mixing bowl, use an electric mixer to cream together 1/2 cup butter, 1/2 cup white sugar, and 1/4 cup brown sugar until smooth. Then, add in 2 eggs one at a time, beating continuously until you achieve a creamy mixture.

Gradually add the dry ingredients to the wet mixture, followed by 1 1/2 cups butterscotch chips and 1 cup rolled oats. Mix until a smooth dough forms.

Press the dough evenly into the prepared baking pan, making sure to cover the entire surface. Sprinkle the top with an additional 1/2 cup butterscotch chips.

Place the baking pan in a preheated oven and bake for 30 to 35 minutes, or until the top is golden brown. Remove from the oven and let it cool completely in the pan before cutting into 24 bars.
