Ingredients
Scale
Brownie Layer:
1 cup butter, softened
10 ounces white chocolate, chopped
1 ¼ cups granulated sugar
4 large eggs
2 cups all-purpose flour
1 tablespoon vanilla extract
½ teaspoon salt
½ cup rainbow sprinkles
Buttercream Frosting:
1 cup butter, softened
4 cups powdered sugar
3 tablespoons heavy cream
3 drops red food coloring
3 drops blue food coloring
1 teaspoon vanilla extract
½ cup assorted rainbow sprinkles for decorating
Instructions
Prepare the Brownie Batter: Preheat oven to 325°F (163°C). Grease a 13×9 inch baking dish or line it with parchment paper. Melt butter and white chocolate in a saucepan over low heat. Let cool slightly. Stir in sugar, then eggs one at a time. Add flour, salt, and vanilla extract; mix well. Fold in sprinkles.
Bake:Pour batter into the prepared pan and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Cool completely on a wire rack.
Make the Frosting: Beat butter in a large bowl until smooth. Gradually add powdered sugar, alternating with heavy cream, until light and fluffy. Stir in vanilla extract.
Color the Frosting: Set aside ½ cup of frosting and tint it blue with food coloring. Divide the blue frosting in half and tint one portion purple with red food coloring.
Frost and Decorate: Frost the cooled brownies with the remaining white frosting. Pipe diagonal blue lines across the bars, then pipe purple lines diagonally in the opposite direction to create a diamond pattern. Top with sprinkles and enjoy!
