This dessert isn’t just easy; it’s a nostalgic trip that combines the beloved flavors of a classic Twix candy bar with the effortless charm of an icebox cake. Imagine layers of buttery shortbread cookies, creamy homemade pudding, a generous drizzle of sweet caramel, and a rich chocolate topping, all magically transforming into a sliceable, cake-like delight after a simple overnight chill. It’s the perfect harmony of textures and tastes, designed to keep you cool and satisfied.
What is an Icebox Cake? The No-Bake Marvel
If you’re new to the concept of an icebox cake, prepare to be amazed. An icebox cake is a type of no-bake dessert that relies on refrigeration to soften cookies or wafers, allowing them to absorb moisture from a creamy filling (often whipped cream or pudding) and transform into a tender, cake-like texture. No baking, no fuss, just pure deliciousness. The magic happens during the chilling process, as the layers meld together, creating a dessert that’s surprisingly sophisticated for its simplicity.
This particular Twix-inspired rendition takes the icebox cake concept to a whole new level of decadence. We’ve replaced traditional wafers with sturdy shortbread cookies, which perfectly mimic the biscuit base of a Twix bar. The result is a dessert that feels incredibly indulgent, yet requires minimal effort on your part. Once you try your first slice, you’ll understand why we’re so hooked on this brilliant dessert category!
Why This Twix Icebox Cake Will Be Your New Favorite
There are countless reasons to fall in love with this Twix Icebox Cake. First and foremost, it’s incredibly easy and quick to assemble. You won’t spend hours in the kitchen, making it ideal for busy weekdays, spontaneous gatherings, or just a treat for yourself. The preparation time is minimal, leaving you free to enjoy the warmer months without being tied to the stove.
But ease doesn’t mean compromising on flavor. This cake delivers a symphony of tastes and textures. The homemade pudding, crafted with brown sugar, adds a depth of caramel-like sweetness that complements the store-bought (or homemade, if you prefer!) caramel sauce. The shortbread cookies provide that essential crunchy-yet-soft texture, and the rich chocolate topping, studded with actual chopped Twix bars, makes every bite feel like a celebration. It’s a dessert that truly captures the essence of a Twix bar in a luscious, cake-like form.
Homemade Pudding vs. Store-Bought: A Delicious Choice
While this recipe calls for a simple homemade pudding, which adds a fresh, rich flavor that truly elevates the cake, don’t let it intimidate you. The pudding comes together quickly with basic pantry staples like brown sugar, flour, milk, and cream. The effort is minimal, and the reward is a smooth, creamy filling that tastes far superior to anything from a box. However, if time is of the essence or you simply prefer the convenience, a high-quality store-bought pudding can certainly be used in a pinch. Just be sure to choose one that’s thick and rich enough to hold up in the layers.
One common concern with icebox cakes is the “soggy” factor. Rest assured, with this recipe, your cookies will not be soggy. Instead, they absorb just enough moisture from the pudding and caramel over the 24-hour chilling period to become wonderfully soft and tender, melting in your mouth like a delicate cake layer. It’s a transformation that truly needs to be experienced to be believed, creating a texture that’s unique and utterly delightful.
Crafting Your Twix Icebox Cake: Tips for Perfection
To ensure your Twix Icebox Cake turns out perfectly every time, here are a few expert tips:
- Plan Ahead for Chilling: The 24-hour refrigeration period is crucial. It’s not just a suggestion; it’s essential for the cookies to soften and the flavors to meld. This makes it an ideal make-ahead dessert for parties and gatherings.
- Cookie Arrangement: Don’t stress too much about filling every tiny gap when laying down the cookies. Break some to fit as best you can in your 8×8 pan. The pudding will seep into the cracks and create a cohesive cake.
- Pudding Consistency: When making the homemade pudding, ensure it thickens properly on the stove. It should be rich and creamy, not watery, to give the cake its structure and luxurious mouthfeel.
- Caramel Choice: While store-bought caramel sauce is convenient, feel free to use your favorite homemade caramel recipe if you have one. Both work beautifully in this cake.
- Twix Topping: The chopped Twix candy bars on top aren’t just for decoration; they add an extra layer of crunch and authentic Twix flavor that truly brings the concept home.
Adjusting Your Layers: Cookie-to-Pudding Ratio
The recipe as written provides a fantastic balance, but we understand that dessert preferences vary. This recipe has a slightly higher cookie-to-pudding ratio, which gives it a more substantial, “cake-like” body. However, if you’re a pudding fanatic and crave more of that creamy goodness, you have options! You could remove one layer of cookies to increase the pudding presence in relation to the cookie, or simply make a little extra pudding to ensure all layers are generously coated. The beauty of an icebox cake is its flexibility – feel free to experiment and find your perfect balance!
Variations & Customizations
Once you’ve mastered the classic Twix Icebox Cake, feel free to get creative with variations:
- Different Cookies: While shortbread is key for the Twix theme, consider graham crackers, vanilla wafers, or even chocolate cookies for other flavor profiles.
- Pudding Flavors: Swap the brown sugar pudding for a vanilla, chocolate, or butterscotch pudding for a different twist.
- Alternative Candy Bars: Instead of Twix, try chopped Snickers for a peanut-caramel-chocolate explosion, or even crushed Oreos for an Oreo icebox cake.
- Nutty Additions: Sprinkle toasted pecans or almonds between layers for added crunch and flavor.
- Whipped Cream: For an even lighter texture, you can fold some whipped cream into your cooled pudding or use it as an additional layer.
This Twix Icebox Cake is more than just a dessert; it’s a summer essential. It’s the perfect sweet ending to a barbecue, a delightful treat for a potluck, or just a cool, refreshing indulgence after a long day. Its simple preparation and incredible flavor make it a true winner. So, ditch the oven, embrace the chill, and get ready to enjoy a truly unforgettable no-bake experience!
Twix Icebox Cake

Ingredients
- PUDDING:
- 2/3 cup packed brown sugar
- 1/4 cup all purpose flour
- pinch of salt
- 1 cup heavy cream
- 1 cup milk
- 3 large egg yolks lightly beaten
- 2 tablespoons butter
- 1 teaspoon vanilla
- LAYERING ITEMS:
- 2 packages Simply Made Butter Cookies
- 1/2 cup caramel syrup
- 1-2 1.79 oz Twix candy bars, chopped
- CHOCOLATE TOPPING:
- 1 cup semi sweet chocolate chips
- 1/2 cup butter cut into small pieces
- 1/4 cup heavy cream
- 2 tablespoons sugar
- 2 teaspoons vanilla
Instructions
-
PUDDING: In a medium sized saucepan, combine the brown sugar, all-purpose flour, and a pinch of salt. Gradually whisk in the heavy cream and milk until smooth. Cook this mixture over medium heat, stirring constantly, until it begins to thicken. Remove the pan from the heat. In a separate bowl, lightly beat the egg yolks. Temper the egg yolks by slowly whisking in at least half of the hot pudding mixture into them (this prevents the eggs from scrambling). Then, pour the tempered egg yolk mixture back into the saucepan with the remaining hot pudding. Return to medium heat and continue to cook, stirring, until the pudding reaches your desired thickened consistency. Remove from heat and stir in the butter and vanilla extract until fully incorporated. Set the pudding aside to cool slightly.
-
Prepare an 8×8 inch baking pan by lining it with foil, leaving an overhang on the sides for easy lifting later. Arrange a single layer of shortbread cookies at the bottom of the pan. You may need to break some cookies to fit snugly, but don’t worry about every single nook and cranny. Spread half of the cooled pudding evenly over the cookie layer. Drizzle half of the caramel syrup over the pudding. Repeat this layering process: add another layer of cookies, followed by the remaining pudding and then the remaining caramel sauce. Finish with a final layer of cookies on top.
-
CHOCOLATE TOPPING: In a small microwave-safe bowl, combine the semi-sweet chocolate chips, cut butter pieces, sugar, and 1/4 cup heavy cream. Microwave in 15-second intervals, stirring thoroughly after each interval, until the mixture is smooth and melted. Stir in the vanilla extract. Pour this rich chocolate topping evenly over the top layer of cookies. Immediately sprinkle the chopped Twix candy bars over the chocolate. Cover the pan loosely with plastic wrap or the foil overhang and refrigerate for a minimum of 24 hours. This crucial chilling time allows the cookies to soften and the flavors to fully meld, creating that signature icebox cake texture. Store any leftover Twix Icebox Cake in an airtight container in the refrigerator. Enjoy!
