Preparation Steps

• Preheat your oven to 350°F (175°C) and line a 9x13-inch baking pan with parchment paper.
• In a bowl, whisk together the flour, baking powder, and salt. Set aside.
• In a separate large bowl, mix melted butter, brown sugar, and granulated sugar until smooth.
• Add eggs and vanilla extract to the butter-sugar mixture and mix until well combined.
• Gradually add the dry ingredients to the wet ingredients, stirring slowly until just combined.
• Fold in cranberries, pistachios, and white chocolate chips until evenly distributed.
• Spread the batter evenly in the prepared baking pan. Bake for 25-30 minutes or until the edges are golden brown.
• Allow to cool in the pan on a wire rack before cutting into squares and serving.
