Valentine's Day Brownies are deep dish chewy chocolate treats, covered in homemade chocolate frosting and topped with festive candies! These will send you to the moon and back!
Line a half sheet pan with parchment paper and lightly spray with cooking spray. Set aside.
Open the four packages of ready to bake brownies and place onto the prepared baking sheet. Press into the pan and even out to create a mostly flat sheet of brownie. Bake 25-30 minutes or slightly undercooked. Remove from the oven and cool 20 minutes. {This time as it's cooling will cook the brownies completely!}
While the brownies are cooling, make the frosting. Whip butter and cocoa together until smooth in large bowl. Stir in vanilla and powdered sugar. Slowly stream in milk until frosting reaches desired consistency. Scrape sides and whip again until light, fluffy and smooth, 1-2 minutes.
Spread prepared frosting over completely cooled brownies and cut into 24 even squares. Top with sprinkles and candies. Serve or cover with plastic wrap and store for up to 3 days on the counter.
