To Prep: Preheat oven to 350°F (175°C). Line an 8-inch square baking pan with parchment paper.
In a large mixing bowl, combine hot melted butter with the chocolate chips, stirring together until the chocolate is completely melted and smooth.
Add the sugar and eggs, whisking together until well combined.
Stir in a couple drops of green food coloring, vanilla extract, and vinegar.
Add the flour, baking powder, and salt, mixing until just combined.
Pour the brownie batter into the prepared pan and spread evenly.
Bake for 45-50 minutes, or until a toothpick inserted in the center comes out with only a few moist crumbs. Allow brownies to cool completely before frosting.
Frosting Directions
In the bowl of a stand mixer (or in a large mixing bowl with an electric hand mixer), beat together softened cream cheese and butter until smooth and creamy.
Add the powdered sugar, salt, and vanilla extract, mixing until well combined and fluffy.
Spread the frosting evenly over the cooled brownies.
Top with green sprinkles.

Notes
Nutrition information is an estimate only.Prep Tips:
Yield - This will depend on how large or small you cut the brownies. If cutting into equal portions, you will get either 9 or 16 squares (either 3 rows of 3 or 4 rows of 4)
Food Coloring - You can use your favorite type of food coloring for this recipe. If you want to avoid artificial dyes, this is a good plant-based food coloring option. I recommend starting with a few drops, stirring, and seeing how the batter looks before adding more. You can always add more food coloring, but if you add too much, you can't take it away.
Storage - Once frosted, the brownies will need to be refrigerated, as the icing contains cream cheese (dairy). They should keep for 3-4 days in an airtight container in the fridge.
