Start by preheating your oven and spreading the pitted cherries evenly on a baking sheet. Sprinkle them lightly with sugar and roast until they soften and release their juices. This step intensifies their sweetness and removes excess moisture. Let them cool slightly before adding to the batter.
Melt the butter and chocolate chips together until smooth and glossy. I usually do this gently to avoid burning the chocolate. Whisk in the sugar, eggs, and vanilla until fully combined. The mixture should look thick and shiny at this stage.
In a separate bowl, combine flour, cocoa powder, and salt. Mixing these first ensures even distribution and prevents clumps. Slowly fold the dry mixture into the wet ingredients. Be careful not to overmix, as that can make the brownies tough.
Gently fold the roasted cherries into the batter, including some of their syrupy juices. This gives the brownies pockets of intense cherry flavor. Make sure they’re evenly distributed without crushing them too much.
Pour the batter into a lined baking pan and spread it evenly. Bake until the edges are set but the center is slightly soft. A toothpick should come out with moist crumbs, not wet batter. Let the brownies cool completely before slicing for clean edges.
