I keep a box of Fun Size Twix in my pantry for a reason: they elevate ordinary chocolate into something deceptively fabulous. These Twix Brownies fold that candy right into the batter, giving you chewy caramel, crunchy cookie, and fudgy brownie in one bite. They’re the kind of dessert people fight over at the office and request for birthdays.
This recipe is straightforward and forgiving. The method hinges on melting chocolate and butter gently, folding in flour without overworking, and layering candy so it becomes a pleasant surprise in every square. I’ll walk you through the exact steps I use in the test kitchen and share tips so your batch comes out glossy, tender, and studded with Twix pieces.
Make them for a crowd—or keep them for yourself. They’re portable, slice well once cooled, and the caramel drizzle right before serving is the finishing touch that makes them look and taste special.
Gather These Ingredients

Ingredients
- 4 ounces unsweetened chocolate; coarsely chopped — provides intense chocolate flavor and structure for fudgy brownies.
- 3/4 cup unsalted butter, cut into cubes — enriches the batter and keeps the texture tender; unsalted lets you control seasoning.
- 1 1/4 cups sugar — sweetens and helps create a glossy crust.
- 3 large eggs — bind and add richness; room temperature eggs incorporate more evenly.
- 1 teaspoon pure vanilla extract — lifts the chocolate and adds depth.
- 1/4 teaspoon salt — balances sweetness and sharpens chocolate notes.
- 1 cup all-purpose flour — provides structure; measure with a spoon-and-level for accuracy.
- 12 Fun Size Twix Bars, each cut into thirds — the candy star of the show: caramel, cookie, chocolate all in one piece.
- 10 individually wrapped caramel candies (I used Kraft) — for the caramel sauce that finishes the brownies; unwrap before melting.
- 2 tablespoons heavy cream — loosens the caramel for drizzling and keeps it glossy.
Cooking (Twix Brownies): The Process
- Preheat oven to 350°F. Line an 8×8-inch baking pan with foil and spray the foil with nonstick cooking spray; set pan aside.
- Cut each Fun Size Twix bar into thirds and set the pieces aside. Unwrap the 10 caramel candies and set them aside for the sauce.
- Place the chopped unsweetened chocolate and cubed butter in a microwave-safe bowl. Microwave at 50% power in 30-second increments, stirring between each increment, until the butter is melted and the chocolate is smooth.
- Stir the chocolate-butter mixture until fully combined and smooth. Whisk in the sugar until incorporated, then whisk in the eggs, vanilla extract, and salt until the mixture is smooth and uniform.
- Gradually add the all-purpose flour to the chocolate mixture, stirring just until no dry streaks remain (do not overmix).
- Spread half of the brownie batter evenly into the prepared pan (use a spatula to smooth the surface). Arrange the Twix pieces in an even layer over the batter.
- Spoon the remaining half of the batter over the Twix layer and spread gently to cover the candy pieces as evenly as possible.
- Bake at 350°F for 30–35 minutes, or until a toothpick inserted near the center comes out with a few moist crumbs (avoid overbaking). Remove the pan from the oven and place it on a cooling rack to cool completely.
- Once the brownies are completely cool, lift them from the pan using the foil and transfer to a cutting surface. Cut the brownies into squares.
- To make the caramel sauce, place the unwrapped caramel candies and heavy cream in a microwave-safe bowl. Microwave at 50% power in 30-second increments, stirring frequently, until the caramels are melted and the mixture is smooth. Drizzle the warm caramel over the cut brownies and serve immediately.
Why It Deserves a Spot

These brownies check multiple boxes: deep chocolate flavor, the crunch-and-chew of Twix cookie and caramel, and a caramel drizzle that keeps each bite moist. They’re not just “a brownie with candy” — the Twix layer becomes an integrated textural surprise. The unsweetened chocolate keeps the final dessert from tasting cloying, so the candy pieces remain bright instead of overwhelming.
They also travel well. Wrapped individually or stacked in a tin, the squares hold up for potlucks and bake sales. And because the Twix pieces are already small, every serving contains candy distributed throughout, which makes them low-fuss for serving a crowd.
What to Use Instead

If you need or want to swap components, here are practical options that won’t derail the recipe:
- Unsweetened chocolate — you can use an equal weight of semisweet or bittersweet chocolate if you prefer a sweeter, less intense base. If you do, keep an eye on overall sweetness and consider reducing the sugar slightly to taste.
- Fun Size Twix Bars — similar caramel-and-cookie candies work fine. Break them into the same-sized pieces so they layer evenly.
- Caramel candies for the sauce — soft caramel chews from other brands will work; unwrap them the same way and melt with the heavy cream until smooth.
Gear Checklist
- 8×8-inch baking pan — the recipe’s baking time and depth are calibrated for this size.
- Aluminum foil — for lining and easy removal of the brownies.
- Nonstick cooking spray — to make sure the foil-release method works smoothly.
- Microwave-safe bowls — for melting chocolate and making the caramel sauce.
- Rubber spatula and whisk — for folding batter and smoothing layers without overmixing.
- Knife and cutting board — to cut Twix bars and to slice the cooled brownies cleanly.
- Cooling rack — cools the pan evenly so brownies set before slicing.
Missteps & Fixes
Common issues and how I handle them
- Brownies come out dry or cakey — Likely overbaked. Pull them at the earlier end of the 30–35 minute window when a toothpick shows a few moist crumbs. Cooling in the pan helps them finish setting.
- Twix pieces sink to the bottom — If batter is too thin, candy may drop. Make sure the batter is not overthinned; spread half the batter, add Twix, then gently spread the remaining batter. Chill briefly (10–15 minutes) before baking if your batter feels very loose.
- Caramel sauce grainy — Stir frequently while melting at 50% power and don’t overheat. Adding the heavy cream helps smooth the sauce; if graininess appears, a brief whisk with a splash more warm cream can help.
- Chocolate seized during melting — If any moisture gets in, chocolate can seize. Remove from heat and whisk in a small knob of warm butter or a teaspoon of warm cream to bring it back to smoothness.
Fresh Takes Through the Year
Change small elements to keep these brownies feeling seasonal and new.
- Holiday party: Sprinkle flaky sea salt over the caramel drizzle to balance sweetness and make them look festive.
- Summer potluck: Cut into smaller bite-sized squares and arrange on a platter for easy snacking; the caramel stays soft if not over-chilled.
- Fall baking: Add a pinch of warm spices (cinnamon or a tiny bit of ginger) to the batter for a cozy note that pairs well with the caramel.
Notes from the Test Kitchen
I tested this method multiple times to land on the right bake time and candy layering. A few lessons stood out. First, cutting the Twix into uniform thirds creates predictable pockets of candy; if pieces vary, you’ll get uneven distribution. Second, the toothpick test matters here because you want fudgy brownies with moisture, not a dry crumb. Third, the caramel drizzle is best warm and fluid; if it cools, it firms up quickly and won’t spread evenly.
When melting chocolate and butter, I always use the 50% power, 30-second increment approach. It takes a little more time but avoids overheating and dulling the chocolate’s glossy finish. Also, I prefer to let the brownies cool fully before lifting them from the pan—cutting too soon makes a mess; waiting makes neat squares.
Storage Pro Tips
Store cooled brownies in an airtight container at room temperature for up to 3 days. If you plan to keep them longer, refrigerate for up to 5 days, but bring to room temperature before serving to restore softness. For longer storage, wrap individual squares tightly in plastic and freeze for up to 2 months. Thaw in the refrigerator overnight and bring to room temperature before serving; a few seconds in the microwave (5–10 seconds) refreshes the brownie and softens the caramel.
Popular Questions
- Q: Can I make these in a 9×9 pan?
A: You can, but the brownies will be slightly thinner. Start checking for doneness at 25 minutes and watch closely; baking time will be shorter. - Q: Do I have to use Fun Size Twix?
A: Fun Size is convenient because of the pre-wrapped portions and size. Other Twix sizes can work if you cut them into comparable pieces so they layer evenly. - Q: Can I skip the caramel drizzle?
A: Yes. The brownies are still delicious without it, though the drizzle adds a glossy finish and extra caramel flavor that ties the Twix pieces together. - Q: Will the Twix get soggy in the brownies?
A: The cookie inside Twix softens slightly but keeps enough texture to be enjoyable. Proper baking and cooling help maintain a pleasant contrast between candy and brownie.
Let’s Eat
Cut the brownies into squares, drizzle the warm caramel, plate, and watch people’s faces. Serve with strong coffee or a glass of cold milk. For a special touch, add a tiny pinch of flaky salt on top of the caramel right before serving—just enough to highlight the chocolate and caramel without stealing the show.
If you make them, tell me how they turned out and whether you tried any swaps. I love hearing which twists work in real kitchens—and I always test a variation or two on repeat. Happy baking.
