Use Up That Leftover Halloween Stash! Candy Bar Brownies

Halloween has always been a favorite holiday for the kiddos. The excitement of choosing a costume, the thrill of wandering the neighborhood after dark and asking strangers for candy, and the inevitable gorging that follows is exactly what childhood dreams are made of. The day after Halloween in my house can be a little intense. 

Children, grouchy from the prior day’s excitement, are an odd mixture of sleepy and hyped up on sugar. Parents, exhausted from the prep leading up to pulling off a successful holiday, are a little shell-shocked and intimidated by the ridiculous amounts of sugar their children are hoarding. 

And maybe, just maybe, the parents are bargaining with their kids to just hand over all of their peanut butter cups. Not that I would know anything about that. 

The thing is, my kids can’t keep buckets of candy around. If they do, they’ll eat it until they make themselves sick. I hate to ruin the fun and take their candy away, though.


Rich, chewy brownies topped with a simple chocolate frosting and loaded with mini candy bars! This is a kid's dream come true!

These festive candy bar brownies are the perfect solution. Your kids will happily hand over a bucket of treats in exchange for one or two of these loaded brownies. 

Not only are these perfect for using up leftover candy, they’re a really fun way to celebrate the holiday for kids who are too old to trick-or-treat.

My from-scratch recipe below makes the best brownies I’ve ever had the pleasure of devouring. I love how thick, chewy, and fudgy they are. They’re also more of a semi-sweet brownie which is perfect since these are topped with so many sweet candy bars.

The frosting is just a simple ganache made of heavy whipping cream and chocolate chips. You can use dark, semi-sweet, or milk chocolate chips, depending on how sweet you’d like the frosting to be. Spread it all on with this adorable Sweet Creations Halloween Spatula to make halloween as much of a treat for you as it is for the kiddies.Rich, chewy brownies topped with a simple chocolate frosting and loaded with mini candy bars!

As for the candy bar topping, you can go crazy here! Use whatever you have on hand or go out and purchase your favorites just for this recipe. I used a mixture of Reese’s, Hershey’s bars, KitKats, Whoppers, and m&m candies myself. What will you use?

Candy Bar Brownies

Chewy brownies topped with a thick chocolate glaze and mini candy bars!

  • Prep Time: 20
  • Cook Time: 30
  • Total Time: 50 minutes


  • 1 cup (2 sticks) butter
  • 2 1/4 cups sugar
  • 4 large eggs
  • 1 1/4 cups cocoa powder
  • 1 teaspoon salt
  • 1 teaspoon baking powder
  • 1 teaspoon espresso powder, optional
  • 1 tablespoon vanilla extract
  • 1 1/2 cups all-purpose flour
  • 1 cup heavy whipping cream
  • 1 1/2 cups semi-sweet chocolate chips
  • 20 fun sized candy bars


Pre-heat the oven to 350 degrees. Butter a 9×13 baking dish. In small saucepan over low heat, melt butter completely. Stir in sugar and continue cooking for 1 to 2 minutes, stirring constantly. Do not allow sugar mixture to boil. Pour butter mixture into a large bowl or stand mixer and beat on low for 2 minutes to cool. Beat in cocoa powder, eggs, salt, baking powder, espresso powder, and vanilla extract. Mix until well combined. Stir in the flour until smooth and shiny. Spread into prepared pan and bake for 30 minutes or until a tester comes out mostly clean. The edges should be set and the center should still look slightly moist, but not uncooked. Cool on a wire rack. After brownies have cooled completely, pour cream into a small sauce pan and turn heat to medium. Bring to a simmer. While cream is heating, add chocolate chips to a large bowl. Once cream is simmering, pour over the chocolate chips, cover the bowl with a lid and let sit for five minutes. Whisk together chocolate and cream until smooth and thick. Let cool five minutes before spreading over the brownies. Unrwap the candy bars and arrange them in the frosting. Let sit for 30 minutes before cutting into small bars and serving.
