Preparation Steps

• Preheat oven to 375°F (190°C). Grease and flour a 9x13 inch baking pan.
• In a large bowl, whisk together the flour, granulated sugar, baking powder, and salt.
• In a separate bowl, whisk together the buttermilk, egg, and melted butter.
• Pour the wet ingredients into the dry ingredients and mix until just combined. Do not overmix.
• Spread the batter evenly into the prepared baking pan.
• Bake for 12-15 minutes, or until a toothpick inserted into the center comes out clean.
• Let the bars cool in the pan for 10 minutes before transferring them to a wire rack to cool completely.
• While the bars are cooling, prepare the glaze. In a small bowl, whisk together the powdered sugar, milk, and vanilla extract until smooth. Add more milk if needed to reach desired consistency.
• Once the bars are completely cooled, drizzle the glaze over the top.
• Cut the bars into desired shapes and serve.
