01 - Preheat oven to 350°F. Line a mini muffin tin with paper liners or grease thoroughly.
02 - In a mixing bowl, whisk together melted butter and sugar until glossy. Add eggs and vanilla; whisk until smooth and well combined.
03 - Sift flour, cocoa powder, and salt into the wet mixture. Mix gently until just combined, being careful not to overmix.
04 - Fold in chocolate chips and chopped cherries until evenly distributed throughout the batter.
05 - Spoon batter evenly into the prepared mini muffin cups, filling each about 3/4 full.
06 - Bake for 16-18 minutes, until tops are set and a toothpick inserted into the center comes out with a few moist crumbs.
07 - Let brownie bites cool in the tin for 5 minutes, then transfer to a wire rack to cool completely before adding ganache.
08 - Place chopped chocolate in a heatproof bowl. Heat cream in a small saucepan until just simmering. Pour over chocolate and let sit for 1 minute. Add butter, then stir until smooth and glossy.
09 - Spoon or pipe ganache over each cooled brownie bite. Let set at room temperature for 15-20 minutes or refrigerate briefly before serving.
