01 - Preheat oven to 350°F. Line a mini muffin tin with paper liners or grease thoroughly.
02 - Whisk melted butter and sugar in a mixing bowl until glossy. Add eggs and vanilla; whisk until smooth.
03 - Sift flour, cocoa powder, and salt into the bowl. Mix gently until just combined.
04 - Fold chocolate chips and chopped cherries into the batter.
05 - Spoon batter evenly into mini muffin cups, filling each 3/4 full. Bake for 16-18 minutes until tops are set and a toothpick comes out with moist crumbs.
06 - Let cool in tin for 5 minutes, then transfer to a wire rack to cool completely.
07 - Place chopped chocolate in a heatproof bowl. Heat cream in a small saucepan until just simmering. Pour over chocolate, let sit 1 minute, add butter, then stir until smooth and glossy.
08 - Spoon or pipe ganache over each cooled brownie bite. Let set at room temperature or refrigerate briefly before serving.
