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.

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. This overhang is your handle—it allows you to lift the entire set dessert cleanly out of the pan before slicing.
- Mix & Press: Mix crushed biscuits with melted butter, 2 tbsp caramel sauce, and salt until every crumb is coated. Press firmly into the bottom of the lined pan. Use the flat bottom of a glass to pack it down evenly.
- 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 room temperature mascarpone and softened cream cheese together on medium speed until perfectly smooth. Cold mascarpone seizes when beaten, leaving permanent lumps.
- Flavor It: Add sifted powdered sugar, 1/4 cup caramel sauce, vanilla extract, and cooled espresso. Beat until fully incorporated.
- Whip & Fold: In a separate bowl, beat cold heavy cream until firm peaks. Gently fold into the mascarpone mixture in three additions using a light lifting motion.
- Add the Crunch: Fold in chopped mini Twix bars. Spread over chilled cookie base and smooth flat. Refrigerate 2 hours.
The Caramel Pour
- Temper the Caramel: Warm 1 cup caramel sauce and 1 tbsp heavy cream over low heat until smooth. Cool 5 minutes—if too hot it will melt the cream layer underneath.
- Pour & Spread: Pour slightly warm caramel over the set cream layer, starting from the center. Coax gently to the edges.
- The Long Chill: Return to refrigerator uncovered. Set at least 4 hours; overnight is strongly recommended for cleanest cuts.
Slice & Decorate
- The Hot Knife Trick: Lift dessert using parchment overhang. Dip a sharp knife in boiling water for 10 seconds, wipe completely dry, slice straight down. Reheat knife between every single cut.
- Garnish: Place a whole mini Twix diagonally on each square. Drizzle extra caramel and finish with flaky sea salt right before serving.
Create the Base Layer
- Line a 9×5 loaf pan with parchment overhang, or use two large glass jars for elegant individual presentation.
- Mix crushed biscuits, butter, 1 tbsp caramel sauce, and salt until it resembles wet sand. Press firmly into the base. Chill 15 minutes.
Make the Small-Batch Cream
- Beat room temperature mascarpone and cream cheese until smooth. Add powdered sugar, caramel, vanilla, and espresso.
- Whip 1/2 cup cold heavy cream to firm peaks (happens fast at this small volume!). Fold into cheese mixture. Fold in chopped Twix. Spoon over base. Chill 1.5 hours.
Finish and Serve
- Microwave 1/2 cup caramel + cream about 10 seconds. Let sit 1 minute, then pour over cream layer. Refrigerate 2.5 hours.
- Slice with hot dry knife if using a pan. Top with mini Twix, caramel drizzle, and sea salt before serving.
The Heavy-Duty Base
- Line 9×13 pan with two intersecting sheets of parchment, leaving significant overhang on all sides.
- Mix 3.5 cups crumbs with butter, caramel, and salt. Press down very firmly with a measuring cup bottom. Chill 30 minutes.
Massive Cream Mixing
- Use a stand mixer. Beat room temperature mascarpone and cream cheese until totally smooth.
- Add powdered sugar, caramel, vanilla, espresso. Mix smooth. Whip 1.5 cups cold heavy cream in a separate bowl to firm peaks. Fold into cheese mixture in four batches. Fold in chopped Twix.
- Spread evenly over crust with offset spatula. Chill 3 hours.
The Large Caramel Pour
- Heat 1.5 cups caramel + cream until fluid but not hot. Pour over set cream, tilting pan to reach corners.
- Overnight chill mandatory (minimum 8 hours). The center of a 9×13 needs this time to firm up.
Party Presentation
- Lift block out using parchment. Use a large chef’s knife dipped in boiling water, wiped dry. Slice straight down, wipe, reheat, repeat for all 18–24 squares.
- Place mini Twix on every square. Set up a caramel + sea salt station so guests can drizzle their own slices.
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: 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 versions 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 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 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 flavor overpowers 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, 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 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.
