Creating Black Forest Brownies can be straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking pan.
2. Mix Wet Ingredients: In a large bowl, combine melted butter and granulated sugar. Mix well until combined. Add eggs and vanilla, stirring until smooth.
3. Combine Dry Ingredients: In another bowl, sift together the flour, cocoa powder, baking powder, and salt.
4. Mix Ingredients: Gradually add the dry ingredients to the wet mixture, stirring until just combined. Do not overmix.
5. Add Cherries and Chocolate Chips: Gently fold in the chopped cherries and semi-sweet chocolate chips.
6. Pour Batter: Pour the brownie batter into the prepared baking pan, spreading it evenly.
7. Bake: Place in the oven and bake for 25-30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
8. Cool: Remove from the oven and allow the brownies to cool in the pan for about 30 minutes. Then transfer them to a wire rack to cool completely.
9. Prepare Whipped Cream: In a mixing bowl, combine heavy whipping cream, powdered sugar, and vanilla extract. Whip until soft peaks form.
10. Top Brownies: Once the brownies are completely cool, spread a generous layer of whipped cream on top. Garnish with additional cherries if desired.
11. Slice and Serve: Cut into squares or rectangles and serve.
