Loaded Junk Food Brownies

Please share this post with your friends 🤗

These brownies are unapologetically decadent: a fudgy chocolate base loaded with pockets of chocolate chips and finished with a shiny milk chocolate ganache, then buried under a joyful avalanche of peanut butter cups, kettle corn, and potato chips. They’re exactly what you reach for when you want something rich, crunchy, salty, and utterly nostalgic all at once. Practical, messy, and irresistible—these are crowd-pleasers for parties, movie nights, or whenever you need a dessert that makes people grin.

I test recipes to make sure they work in a real home kitchen, with clear steps and minimal fuss. This one comes together quickly: a single bowl for the brownies, a simple stovetop ganache, and an assembly that encourages happy chaos. Read through the ingredients and method once, then follow the step-by-step instructions below. You’ll end up with brownies that are fudgy, not cakey, and a topping that stays crunchy if you serve within a day.

What to Buy

• 12 tablespoons (1 1/2 sticks) unsalted butter — for richness and glossy texture in the brownies; cut into pieces so it melts evenly.
• 3.5 ounces semisweet chocolate, finely chopped — melts with the butter to form the brownie base; chopping helps it melt smoothly.
• 3/4 cup all-purpose flour — provides structure; measure by spooning into the cup and leveling for accuracy.
• 2/3 cup unsweetened cocoa powder — deep chocolate flavor; use natural or Dutch-processed as you prefer.
• 1 teaspoon baking soda — slight lift and chew; part of the leavening team.
• 1/2 teaspoon baking powder — balances the soda and helps set the crumb.
• 1/2 teaspoon fine sea salt — enhances chocolate flavor; fine salt dissolves better.
• 1 1/2 cups granulated sugar — sweetness and some structure; granulated keeps the crackly top.
• 2 large eggs plus 1 large egg yolk, lightly beaten — eggs add richness and help set the brownies; reserve for combining as directed.
• 2 teaspoons vanilla extract — flavor rounder; pure vanilla gives the best result.
• 2/3 cup chocolate chips — pockets of melty chocolate dispersed through the batter.
• 9 ounces milk chocolate, finely chopped — for the ganache topping; chopping ensures it melts quickly and evenly.
• 1/2 cup heavy cream — warmed and poured over chocolate to make a smooth ganache.
• 1 cup mini or chopped regular peanut butter cups — salty-sweet candy for the topping; minis stick and distribute well.
• 2 cups kettle corn — adds sweet crunch; sprinkle while ganache is wet so it adheres.
• 1 cup potato chips, coarsely crushed — provides salty crunch and texture contrast; use ridged for durability if available.

Loaded Junk Food Brownies Cooking Guide

Prep and dry mix

1. Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving an overhang for easy removal, or lightly spray the pan with nonstick spray.
2. In a small bowl, whisk together 3/4 cup all-purpose flour, 2/3 cup unsweetened cocoa powder, 1 teaspoon baking soda, 1/2 teaspoon baking powder, and 1/2 teaspoon fine sea salt. Set this dry mix aside.

Melt chocolate and combine wet ingredients

3. Place 12 tablespoons unsalted butter (cut into pieces) and 3.5 ounces finely chopped semisweet chocolate in a large, microwave-safe bowl. Microwave on medium power for about 45–60 seconds, stopping every 15 seconds to stir. Continue until the chocolate is mostly melted, then stir until completely smooth.
4. Let the melted chocolate mixture sit for 5 minutes to cool slightly so it won’t scramble the eggs when added.
5. Whisk 1 1/2 cups granulated sugar into the warm chocolate until combined. Add 2 large eggs plus 1 large egg yolk (lightly beaten) and 2 teaspoons vanilla extract, and whisk until the mixture is smooth and glossy.

Finish the batter and bake

6. Fold the reserved dry ingredients into the chocolate mixture until almost incorporated. Add 2/3 cup chocolate chips and fold gently until the batter is even and no streaks of dry flour remain. Do not overmix.
7. Spread the batter evenly into the prepared 9×13-inch pan, smoothing the top with a spatula.
8. Bake in the preheated 350°F oven for 25 to 30 minutes, until the center is set and the top looks puffed. A toothpick inserted near the center should come out with a few moist crumbs but not wet batter.
9. Remove the pan from the oven and let the brownies cool to room temperature in the pan. They may sink slightly in the middle—that’s normal and makes room for the ganache.

Make the ganache and assemble

10. Place 9 ounces finely chopped milk chocolate in a heat-proof bowl. In a small saucepan, heat 1/2 cup heavy cream just until it begins to simmer around the edges—do not boil.
11. Pour the hot cream over the chopped milk chocolate and let it sit undisturbed for 30 seconds, then stir until the mixture becomes a smooth, glossy ganache. Reserve 1/4 cup of ganache if you’d like to drizzle extra at the end.
12. Pour the remaining ganache evenly over the cooled brownies, spreading gently with a spatula if needed.
13. While the ganache is still wet, sprinkle 1 cup mini or chopped peanut butter cups, 2 cups kettle corn, and 1 cup coarsely crushed potato chips evenly over the top. Press the toppings lightly into the ganache so they stick.
14. Cover the pan and refrigerate until the ganache and toppings are set, at least 2 hours or overnight. The brownies are fudgiest the next day.
15. Store covered in the refrigerator for up to 3 days; for the crunchiest topping, serve within 1 day of making.

Why You’ll Keep Making It

These brownies hit multiple textures—gooey, fudgy, crunchy, and salty-sweet—which keeps them interesting bite after bite. They’re flexible: swap candy or chips based on what you have, and the ganache keeps the toppings bonded so the plate doesn’t become a crumb storm. They travel well to potlucks (keep chilled) and make a statement without complicated techniques.

Dairy-Free/Gluten-Free Swaps

• Dairy-free: Replace butter with a vegan butter stick (use same amount) and swap both the milk chocolate (9 oz) and semisweet chocolate (3.5 oz) for dairy-free chocolate options. Use coconut cream or a dairy-free heavy cream substitute for the ganache (same amount) but expect a slightly different texture.
• Gluten-free: Use a 1:1 gluten-free all-purpose flour blend in place of the 3/4 cup all-purpose flour. Check your kettle corn and potato chips for gluten ingredients or cross-contamination; choose certified gluten-free snacks.

Hardware & Gadgets

• 9×13-inch baking pan — essential for the right thickness and bake time.
• Parchment paper — makes removal and cutting easier.
• Microwave-safe bowl or double boiler — for melting butter and chocolate safely.
• Heat-proof bowl and small saucepan — for making ganache.
• Rubber spatula and whisk — for folding and smoothing the batter and ganache.
• Sharp knife or bench scraper — for cutting neat squares once set.

Steer Clear of These

• Overbaking: Don’t bake until fully dry. Overbaked brownies lose fudginess.
• Boiling the cream: Boiling cream can scorch and create a grainy ganache—heat only until it simmers at the edges.
• Adding eggs to very hot chocolate: If the melted chocolate is too hot, eggs can scramble—allow it to cool for about 5 minutes before adding sugar and eggs.
• Waiting to top: If you wait until the ganache is fully set, the toppings won’t adhere. Add them while the ganache is still wet.

Better Choices & Swaps

• Chocolate: Use a higher-quality semisweet or milk chocolate for better depth; not all chocolate chips melt equally, so chopping bars helps.
• Kettle corn alternative: If you want less sweetness, swap kettle corn for plain popcorn tossed with a little sugar and salt, or use caramel corn for extra chew.
• Salt balance: If you love salt, add a light sprinkle of flaky sea salt over the ganache just before the toppings to sharpen the flavors.

Pro Tips & Notes

• Room temperature eggs: Use eggs at room temperature for better emulsion and even baking.
• Chop chocolate finely: Finely chopped chocolate melts faster and creates a smoother chocolate-butter base.
• Batter thickness: The batter should be thick but spreadable; if it’s too stiff, your chocolate likely cooled too much—briefly warm slightly and stir.
• Cutting neat squares: For clean slices, chill until fully set, then run a sharp knife under hot water, wipe dry, and slice in a single smooth motion.
• Make ahead: These are often best the day after making, once the ganache fully firms and flavors meld.

Best Ways to Store

• Short-term: Cover and refrigerate for up to 3 days. Bring to room temperature for 20–30 minutes before serving to soften the chocolate slightly.
• For crunch: Serve within the first day to preserve the crispiest kettle corn and potato chips. Toppings soften over time from moisture in the ganache.
• Freezing: You can freeze cut brownies in a single layer on a baking sheet, then transfer to an airtight container for up to 1 month. Thaw in the refrigerator to avoid soggy toppings; expect some texture loss in the chips and popcorn.

Quick Questions

• Can I use salted butter? Yes—reduce or omit added salt if you only have salted butter, since the recipe calls for 1/2 teaspoon fine sea salt.
• Can I swap the peanut butter cups? Absolutely. Use chopped chocolate bars, M&Ms, or any candy you love—just keep the 1 cup quantity for balance.
• Will the ganache set at room temperature? Ganache will firm at room temperature if cool enough, but chilling speeds the set and keeps toppings intact.
• Why do the brownies sink in the middle? Slight sinking is normal for fudgy brownies; the ganache actually fills that well and creates a great profile.
