Instructions

1. Prepare your 8-inch or 9-inch baking pan by coating it with butter or lining with parchment paper, ensuring complete coverage for easy brownie removal.
2. Sift 1 cup all-purpose flour, ¾ cup unsweetened cocoa powder, ½ teaspoon baking powder, and ½ teaspoon salt together in a medium mixing bowl until completely combined and lump-free.
3. Melt ¾ cup butter in a large bowl, then whisk in 1 cup granulated sugar and ½ cup brown sugar until smooth and well-incorporated.
4. Crack 2 large eggs into the butter-sugar mixture one at a time, stirring thoroughly after each addition to create a uniform blend.
5. Pour 1 teaspoon vanilla extract into the wet ingredients and mix until fragrant and fully integrated.
6. Gently fold the dry ingredient mixture into the wet ingredients, stirring just until no flour streaks remain to maintain a tender brownie texture.
7. Dice 1 ½ cups fresh rhubarb into small, uniform pieces and fold into the batter along with ½ cup chocolate chips if desired.
8. Transfer the batter to the prepared pan, spreading evenly with a spatula to create a smooth surface.
9. Bake at 350°F for 30-35 minutes, rotating the pan halfway through to ensure even cooking.
