Step-by-Step Instructions
- Preheat your oven to 350°F (175°C) and prepare a 9x13-inch baking pan by lining it with parchment paper.
- Cream together the softened unsalted butter and granulated sugar until the mixture is light and fluffy, about 3-4 minutes.
- Add the large eggs, one at a time, mixing well after each addition, then pour in the vanilla extract and mix until just combined.
- In a separate bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking powder, and salt until well combined.
- Gradually add the dry ingredients to the butter mixture, stirring until just combined to form a soft dough.
- Transfer the cookie dough into the prepared baking pan, spreading it evenly to promote even baking.
- Bake for 18-22 minutes, until the edges are set and the center looks slightly puffed.
- Let the bars cool in the pan on a wire rack for about 30-40 minutes.
- In a medium bowl, beat softened butter with an electric mixer until smooth, then gradually add powdered sugar and cocoa while mixing.
- Spread the frosting evenly over the cooled bars and optionally decorate with chocolate or rainbow sprinkles.
- Use the parchment paper overhang to lift the bars from the pan, slice into squares, and serve.
