BUTTERSCOTCH BLONDIES

Steps:

• Preheat oven to 350 degrees. Line a buttered 8-inch square baking pan with foil or parchment paper, allowing a 2-inch overhang. Butter lining (excluding overhang); set pan aside.
• Whisk together flour, baking powder, and salt in a medium bowl; set aside.
• Put butter and sugar in the bowl of an electric mixer fitted with the paddle attachment; mix on medium speed until pale and fluffy, about 3 minutes. Add eggs and vanilla; mix until combined. Reduce speed to low. Add flour mixture, and mix, scraping down sides of bowl, until well combined. Mix in butterscotch, cashews, and toffee.
• Pour batter into prepared pan; spread evenly with a rubber spatula. Bake until golden brown and a cake tester inserted into blondies (avoid center and edges) comes out with a few crumbs but is not wet, 42 to 45 minutes. Let cool slightly in pan, about 15 minutes. Lift out; let cool completely on a wire rack before cutting into squares. Blondies can be stored in an airtight container at room temperature up to 3 days.
