Twix Tiramisu
The No Bake Caramel Dessert Everyone Is Talking About!
A cookie base, caramel mascarpone cream, hidden chopped Twix pieces, and a glossy poured caramel top.
What happens when you take the most iconic Italian dessert of all time and rebuild it around everyone’s favorite caramel chocolate candy bar? You get Twix Tiramisu—a no bake layered dessert so beautiful, so completely indulgent, and so easy to make that it has become the most saved dessert recipe on the internet this season.
A buttery cookie base, caramel mascarpone cream, chopped Twix pieces hidden inside every layer, a smooth glossy set caramel top, and a whole mini Twix bar placed on every single slice. This is the dessert that gets texted around friend groups, screenshot saved, and made for every party until further notice.
Traditional tiramisu is a masterpiece that has been perfecting itself since the 1960s. This Twix version keeps the spirit of the original—the layered structure, the creamy filling, the no-bake refrigerator set method—and completely reinvents the flavor profile around caramel, chocolate, and shortbread crunch. The espresso note is still present, subtle and in the background, but the absolute star of every bite is the caramel.

Step by Step Instructions
Build the Base
- Prep the Pan: Line a 9×9 inch square baking pan with parchment paper, leaving plenty of overhang on all four sides. Why? This overhang is your handle. It allows you to lift the entire set dessert cleanly out of the pan before slicing for perfect presentation.
- Mix & Press: In a bowl, mix your finely crushed biscuits with the melted butter, 2 tbsp of caramel sauce, and a pinch of salt until every crumb is coated. Press this mixture firmly into the bottom of the lined pan. Pro Tip: Use the flat bottom of a glass to pack it down evenly so the crust doesn’t crumble later.
- Chill: Place the pan in the refrigerator for 20 minutes to solidify the butter while you make the filling.
Whip the Cream Filling
- The Cheese Base: Beat the room temperature mascarpone and softened cream cheese together on medium speed until perfectly smooth. Why room temp? Cold mascarpone seizes when beaten, leaving permanent lumps in your dessert.
- Flavor It: Add the sifted powdered sugar, 1/4 cup caramel sauce, vanilla extract, and cooled espresso. Beat until fully incorporated.
- Whip & Fold: In a separate bowl, beat the cold heavy cream until it holds firm peaks. Using a rubber spatula, gently fold the whipped cream into the mascarpone mixture in three additions. Use a light, lifting motion—you want to keep the air in the cream.
- Add the Crunch: Gently fold in the chopped mini Twix bars until just distributed. Spoon this entire mixture over your chilled cookie base and smooth the top perfectly flat with an offset spatula. Refrigerate for 2 hours to set the cream.
The Caramel Pour
- Temper the Caramel: Warm the 1 cup of caramel sauce and 1 tbsp heavy cream in a small saucepan over low heat until smooth and just barely pourable. Let it cool for 5 minutes. Why? If the caramel is too hot, it will instantly melt the chilled cream layer underneath and ruin your clean layers.
- Pour & Spread: Pour the slightly warm caramel over the set cream layer, starting in the center. Gently coax it to the edges.
- The Long Chill: Return the pan to the refrigerator, uncovered. Let it set for at least 4 hours, though overnight is strongly recommended for the cleanest cuts.
Slice & Decorate
- The Hot Knife Trick: Lift the dessert out of the pan using the parchment overhang. Fill a tall glass with boiling water. Dip a sharp knife in the hot water, wipe it completely dry with a towel, and slice straight down. Clean and reheat the knife between every single cut. Why? This is the only way to cut through the caramel layer without cracking it.
- Garnish: Place a whole mini Twix bar diagonally on top of each square. Right before serving, generously drizzle extra caramel sauce over each slice and finish with a pinch of flaky sea salt.
Create the Base Layer
- Prep your Vessel: Line a 9×5 inch loaf pan with parchment overhang, OR use two large, clean glass jars/ramekins for an elegant individual serving presentation (no parchment needed for jars).
- Mix the Crust: Mix the crushed biscuits, melted butter, 1 tbsp caramel sauce, and salt until it resembles wet sand. Press this firmly into the bottom of your loaf pan or divide it evenly into your jars.
- Chill: Place in the fridge for 15 minutes to let the butter harden.
Make the Small-Batch Cream
- Beat the Cheeses: Ensure your mascarpone and cream cheese are at room temperature. Beat them together until smooth. Add the powdered sugar, 2 tbsp caramel, vanilla, and espresso, mixing until combined.
- Whip the Cream: In a separate small bowl, whip your 1/2 cup of heavy cream to firm peaks (this will happen very fast with such a small amount!). Gently fold the whipped cream into the cheese mixture.
- Fold & Fill: Fold in the chopped Twix pieces. Spoon the mixture over your base and smooth the top. Chill for 1.5 hours to let this smaller volume set.
Finish and Serve
- The Caramel Top: Warm the 1/2 cup caramel and heavy cream slightly in the microwave (about 10 seconds). Let it sit for a minute so it isn’t piping hot, then pour it over the cream layer.
- Final Set: Refrigerate for at least 2.5 hours. Because the volume is smaller, it will set slightly faster than a full family pan.
- Decorate: If in a loaf pan, use a hot, dry knife to slice it. Top each serving with whole mini Twix, a drizzle of caramel, and sea salt right before digging in!
The Heavy-Duty Base
- Pan Preparation: You will need a large 9×13 inch baking pan. Line it with two intersecting sheets of parchment paper, leaving significant overhang. Why? Lifting a 9×13 dessert out of a pan is heavy work; you need strong parchment handles on all four sides to prevent it from breaking.
- Pack it Tight: Mix the 3.5 cups of crumbs with the melted butter, caramel, and salt. Pour it into the pan. Because the surface area is so large, spend extra time pressing it down with the bottom of a measuring cup to ensure it is incredibly compact. Chill for 30 minutes.
Massive Cream Mixing
- Use a Mixer: Due to the large volume, a stand mixer is highly recommended here. Beat the room temperature mascarpone and cream cheese on medium speed until totally smooth. Do not use cold cheese or you will be fighting lumps all day.
- Flavoring: Add the powdered sugar, caramel, vanilla, and espresso. Mix until smooth.
- Separate Whipping: Whip the 1.5 cups of heavy cream in a separate bowl to firm peaks. Carefully fold this into the heavy cheese mixture in four batches so you don’t deflate the air. Gently fold in the large batch of chopped Twix.
- Layer: Spread this massive amount of cream evenly over the crust. Use an offset spatula to get the corners perfectly level. Chill for 3 hours.
The Large Caramel Pour
- Warm the Topping: Gently heat the 1.5 cups of caramel sauce and heavy cream until fluid but NOT hot to the touch. Pour it over the vast surface of the set cream, tilting the heavy pan slightly to help it run into the corners.
- Overnight Chill (Mandatory): For a 9×13 pan, you must refrigerate this overnight (at least 8 hours). The center needs significant time to firm up enough to support being lifted and sliced.
Party Presentation
- The Hot Knife: Enlist a helper to lift the massive block out of the pan using the parchment. To cut 18-24 clean squares without shattering the caramel, use a large chef’s knife dipped in boiling water and wiped dry. Slice straight down, wipe, reheat, repeat.
- Garnish Station: Place a mini Twix on every single square. Set up a station with warm caramel sauce and sea salt so guests can drizzle their own slices right before eating!
Pro Tips for Perfection
- Room temperature mascarpone is non-negotiable: Cold mascarpone seizes and turns lumpy when beaten, and no amount of mixing will fix it.
- Watch the caramel temperature: When pouring the top layer, too hot melts the cream, too cold sets instantly. Warm to the touch but not steaming is the target.
- Use full-fat dairy: Reduced fat mascarpone or cream cheese do not set firmly enough; your layers will collapse when sliced.
- Don’t skip the parchment overhang: Without it on all four sides, you cannot cleanly remove the dessert from the pan.
- Finish with flaky salt: The salt against the sweet caramel is what makes this taste like it came from a professional pastry kitchen.
Delicious Variations
🥜 Snickers Tiramisu
Swap Twix for Snickers bars throughout, and beat 2 tbsp of peanut butter into the mascarpone cream. Drizzle warm peanut butter on top to serve.
🧂 Salted Caramel Tiramisu
Increase the flaky sea salt in every layer and use an intense salted caramel sauce for the top. Sophisticated and incredibly balanced.
🍫 Chocolate Drizzle Twix
Add a dark chocolate drizzle alongside the caramel drizzle at serving. The combination of dark chocolate and caramel over the cream is extraordinary.
🥂 Individual Twix Cups
Layer all the components in clear dessert glasses or jars for single-serve portions. The beautiful layers are visible, and each cup gets its own mini Twix.
Top Reddit Questions
Q: “Can I make this ahead of time for a party?”
Yes, it’s one of the best make-ahead desserts! The assembled dessert (without the Twix on top) keeps perfectly in the fridge for up to 3 days. The flavor actually improves significantly after the first 24 hours as the caramel soaks into the cookie base. Just place the fresh Twix on top right before serving.
Q: “My caramel top layer cracked when I sliced it. How do I get clean cuts?”
A cracked caramel top has one simple fix: a hot knife. Fill a tall glass with boiling water, dip your sharpest knife into it for 10 seconds, wipe it completely dry, and slice straight down (no sawing). Wipe and reheat the knife between every single cut!
Q: “Can I use a different candy bar instead of Twix?”
Absolutely! Snickers bars are an incredible substitute. Kit Kats create a great wafer crunch. Milky Way bars melt slightly into the cream for pockets of nougat. Just avoid peanut butter-heavy bars (like Reese’s) as the peanut butter can clash with the delicate mascarpone cream.

The History Behind the Dish
The story of Twix Tiramisu is a beautiful collision of a timeless Italian classic and modern internet food culture. Traditional Tiramisu (meaning “pick me up” in Italian) was invented in the Veneto region of Italy in the 1960s. It relied on simple, high-quality ingredients: espresso-soaked savoiardi (ladyfingers), raw egg yolks beaten with sugar, rich mascarpone cheese, and a dusting of bitter cocoa powder.
Fast forward to the 21st century, and the rise of “no-bake refrigerator desserts” in America merged with the structural genius of the Italian original. Home bakers realized that the fundamental architecture of Tiramisu—a sturdy base, a luscious creamy center, and a beautiful top—could be adapted to almost any flavor profile. The egg yolks were often swapped for whipped heavy cream to create a safer, lighter, and more foolproof no-bake filling.
The Twix Tiramisu variation was born out of the social media food era, where visual layers and beloved nostalgic flavors rule. By replacing the ladyfingers with a buttery digestive crust, substituting cocoa for a glossy caramel pour, and hiding actual candy bars inside the delicate mascarpone, chefs created a dessert that bridges the gap between high-end pastry technique and pure, indulgent comfort food.
