First, combine the rum and the preserves and let them sit while you prepare the brownies. This will allow the cherries to absorb the rum. Then preheat the oven to 350 degrees and butter a 9x9 pan, covering it with a piece of buttered, parchment paper

In a large bowl, add the flour, cocoa powder, sugar, sea salt, baking powder, and whisk together. Set aside

Melt the chocolate pieces either in the microwave or on the stovetop, being careful not to burn them

In a separate, large bowl, add the eggs, vanilla extract, melted chocolate, melted butter, pouring in about 2 tablespoons of the rum-jam liquid. Whisk together until it is combined

Slowly pour the flour mixture into the egg mixture and whisk together until a chocolatey batter forms

Pour the batter into the pan. Top the batter with the cherries and any extra juices. You can use the back of a spoon or a knife to blend the jam with the batter

Place in the oven and bake until it has risen, and a toothpick inserted in the center comes out clean

Remove from the pan and place in the wire rack to cool

Cut into 12 pieces

Serve and enjoy!
