Preheat the oven to 350 and prepare an 8x8 pan with parchment or grease and set to the side.
Brown the butter in a small saucepan on low heat. It will melt, foam, and then turn golden brown.
While the butter is melting, chop the chocolate. When the butter is done, pour the butter over the chocolate and add the oil. Mix until the chocolate is fully melted.
In a large bowl, combine the sugars, salt, eggs, and espresso powder. Whisk until light and foamy, about 5-6 minutes. Add in the melted chocolate and mix to combine.
Fold in the flour and cocoa powder, making sure everything is fully combined. Mix in the cherries.
Pour the batter into the prepared pan and bake in the oven for 25-30 minutes. Let the brownies cool in the pan for 10-15 minutes before cutting.
