Ingredients
- Butter: Leave 1 cup of unsalted butter at room temperature for 20 minutes before starting the recipe. Softened butter will cream with the sugar more easily and add more air for fluffier brownies.
- Wet Ingredients: Along with the butter, you’ll need 2 cups of granulated sugar, 4 eggs, and 2 teaspoons of vanilla extract. Bring the eggs to room temperature with the butter.
- Cocoa Powder: To give the brownie batter its chocolate flavor, you’ll need 2/3 cup unsweetened cocoa powder.
- Flour Mixture: You’ll need 1 ¼ cups of all-purpose flour, 1 teaspoon of baking powder, and ½ teaspoon of salt for the dry ingredient mix.
- Candy Bars: You can use whatever candy bars, totaling up to 1 cup. You don’t want to add more than a cup total for the best candy-to-brownie ratio.
- Sprinkles: I also added Halloween-colored sprinkles to use up my extra Halloween baking supplies while I was at it. They aren’t necessary, but they give the chocolatey brownies a festive look.
Chef’s Note: Why I love this recipe!
I love creative recipes, like this one, that allow you to rework leftovers rather than throwing them out. By adding leftover Halloween candy to fudgy chocolate brownies, you get a new take on a classic dessert and use up the candy bars.
These Leftover Candy Brownies are the perfect dessert to bring to a potluck or share with your family. They make an excellent after-dinner dessert or treat for a cozy fall movie night. It’s hard to go wrong with gooey candy bar brownies!
Can This Be Made Ahead of Time?
Yes, making Halloween Brownies ahead of time is a convenient way to handle the holiday rush. I wouldn’t make them more than a day ahead of your party, though; they are best in the first 24 hours, where they are soft and moist.
Baking Recipe Tips & Tricks
- Be sure to sift the cocoa powder with the other dry ingredients before adding them to the recipe. This removes the lumps, so you don’t have to mix the batter as much and are less likely to overmix.
- This works best with chocolate candies or softer candies that you can bite into, such as soft caramels, mini candy bars, and malted milk balls. I wouldn’t use candy like Smarties or Jolly Ranchers.
- If you’re storing brownies for more than a couple of days, adding a slice of bread to the container can help keep them moist.
How to Store
- Store: To keep the recipe fresh, you can cover the brownies with foil or put them in an airtight container. Kept sealed, the brownies can stay good at room temperature for 3-4 days or in the fridge for up to a week.
- Freeze: To freeze the brownies, wait for the recipe to cool, then slice them into squares. Layer the chocolate squares in a single layer in a freezer-safe container. Then, place parchment paper over the layer of brownies before adding more. Continue until all the brownies are placed in the container. You can keep the recipe frozen for up to 3 months. Then, when you’re ready to eat the recipe, take the brownies out of the airtight container and let them sit at room temperature while they come to room temperature.
Frequently Asked Questions
I use leftover candy bars of all types, like Kit-Kats, Snickers, Milk Ways, and any other chocolate bars I have on hand. You could add M&M’s, candy corn, caramels, or other small, softer candy pieces. I would avoid adding gummy candies since you can’t bake them, or hard candies since they can be hard to bite into.
It can be hard to judge when chocolate desserts are done baking because you can’t tell if they’re browning. Brownies are even trickier because you want to take them out of the oven while they’re still fudgy and a little gooey. Check if the brownies are done by sticking a toothpick in the center of the pan after 25 minutes to ensure you don’t over-bake this recipe. The toothpick will come out with some moist crumbs if the brownies are done. If they’re underbaked, you’ll see raw batter on the toothpick, and you should continue cooking longer.
It depends on the kind of topping you’re adding. In this recipe, you’ll add the candy pieces to the brownie batter before baking. That way, the candy pieces will sink down slightly into the batter, baking into the recipe. For other toppings like frosting or a dusting of powdered sugar, you’ll wait until the brownies are baked and cooled.
Variations
- Peanut Butter Cup Brownies: Instead of using all different varieties of leftover candy, you can make this brownie recipe with just one or two specific candies. Chocolate and peanut butter are a classic flavor combo for a reason, and this brownie base tastes amazing with Reese’s Peanut Butter Cups on top. You can cut full-sized peanut butter cups into quarters, sprinkle on mini peanut butter cups, or mix the two. You could also incorporate Reese’s Pieces with this version to add to the peanut butter candy theme.
- More Candy Ideas: Colorful candies like M&Ms and candy corn look great. You could add caramel, chocolate-covered pretzels, almond joys, malted milk balls, or chocolate mint candies, etc.
- Salty Add-ons: You can balance out the sweet candy bars and fudgy chocolate with salty mix-ins like chopped nuts, potato chips, or pretzels.
- Box Mix: You can use a brownie mix and still top off the batter with leftover candy bars. To upgrade your brownie mix, you can swap out the oil in the recipe for melted butter and exchange the water for freshly brewed coffee. This makes rich, gooey, chocolatey brownies that taste like you made them from scratch.
