Preheat the oven to 350°F / 175°C. Butter and line an 8×4" loaf pan with parchment paper.
Wash, pit, and cut the cherries in half.
In a medium sized microwave safe bowl, melt together the butter and 90g (½ c.) chocolate chips in 30 second intervals, stirring in between each interval.
Once the mixture is melted and smooth, whisk in the cocoa powder.
Add in the egg and the sugar and whisk vigorously for at least 1 minute.
Add in the flour and salt. Use a rubber spatula to lightly fold the flour into the ingredients. When there are only a few streaks of flour remaining, add in the remaining 45g (¼ c.) of chocolate chips and the cherries. Fold just until no flour streaks remain.
Pour the brownie batter into your prepared loaf pan. Bake for 20-25 minutes, or until the edges are set and the middle only slightly wobbles.
Whipped Cream
Beat together the heavy cream, sugar, and vanilla until stiff peaks form.
Slice the brownies once they have cooled to room temperature, then top them with whipped cream & more cherries. Serve and enjoy!
