This dreamy layered treat brings together the bold tastes of chocolate cake, gooey caramel, fluffy whipped cream, and crunchy toffee. It's a showstopping dessert that'll wow everyone at your table. With eye-catching layers and a mix of soft and crispy textures, every spoonful delivers pure bliss.
I whipped up this trifle for the first time when my sister turned another year older and I needed something impressive without spending hours in the kitchen. When I carried it to the dinner table, jaws dropped, and now my family asks for it at practically every get-together.
Ingredients
- Devil's Food cake mix: With the box-listed items to make a rich chocolate foundation that cuts through the sweetness everywhere else
- Sweetened condensed milk: Soaks into every bit of cake, making it super moist and extra rich
- Whipped cream: Creates soft, cloud-like sections between the denser parts
- Caramel syrup: Adds sweet, buttery pools throughout each mouthful
- Heath English Toffee Bits: Give that wonderful snap and buttery toffee taste
- King-Sized Heath bar: Tops it all off with a fancy finish that hints at what's inside
Step-by-Step Instructions
- Prepare the Cake:
- Stick to the box directions carefully. The cake needs to be moist to soak up all that sweet milk. Use eggs that aren't cold and mix just enough for a soft texture.
- Cut the Cake into Squares:
- Let the cake cool a bit but cut while still warm. Grab a saw-edged knife to make roughly 1-inch cubes. The warmth helps the cake drink up the sweet milk better, creating that pudding-like feel trifles are known for.
- Add Sweetened Condensed Milk:
- Dump the whole can over your cake chunks, making sure each piece gets coated. Give it about 5 minutes to soak into the warm cake, turning it into a moist, tasty base.
- First Layer in the Trifle Bowl:
- Spread a third of your milk-soaked cake pieces across the bowl bottom. Push down lightly to make a mostly flat surface. This first layer forms the backbone for everything else.
- Add the Whipped Cream, Caramel, and Toffee:
- Spoon a third of your whipped cream over the cake and smooth it out gently. Dribble a third of the caramel in zigzags for good coverage. Toss a third of the toffee bits all over, right to the edges.
- Repeat the Layers:
- Do the same thing twice more. For the middle section, push down a bit to get rid of air bubbles. Try to let some toffee and caramel touch the glass sides so people can see the yummy layers from outside.
- Top with Crushed Heath Bars:
- Put your Heath bar in a ziplock bag and smash it with a rolling pin until you've got some powder and small chunks. Sprinkle over the top layer of cream, putting more in the middle for a nice mound effect.
- Refrigerate:
- Cover your creation with plastic wrap and chill for at least 2 hours, though leaving it overnight works even better. This waiting time lets all the flavors mix together and the textures blend into something amazing.

The caramel syrup is really the game-changer in this trifle. I found this out by chance when I ran out of chocolate sauce once and grabbed caramel instead. The way it creates little pockets of sweet butteriness throughout turns this from a good dessert into an unforgettable one.
Make It Your Own
We all like different amounts of stuff in our trifles. Don't worry about changing up how much caramel, whipped cream, or toffee you add. Some of my relatives want extra caramel drizzled in, while others go crazy for more toffee crunch. This dessert works no matter how you tweak it.
Storage Tips
This trifle stays fresh in your fridge for up to 3 days. The cake gets softer and the flavors grow stronger over time. Put plastic wrap right on the surface to keep the whipped cream from picking up fridge smells. If you're making it way ahead, wait to add the crushed Heath bar until right before you serve it so it looks its best.
Ingredient Substitutions
You can switch things up easily with this treat. If you want something lighter, angel food cake works great instead of Devil's Food. Don't like Heath bars? Try Butterfinger, Snickers, or even crushed Oreos. For a grown-up version, mix in 3 tablespoons of Baileys or Kahlúa with the sweetened condensed milk before you pour it on the cake.

The best thing about this trifle isn't just how good it tastes but how it brings folks together. There's something special about sharing a pretty dessert with friends and family that creates memories that last way longer than the dessert itself.
Frequently Asked Questions
- → Can I make whipped cream at home?
Absolutely! Fresh, homemade whipped cream adds a rich, creamy touch. Just keep it mildly sweet to pair with the other layers.
- → What's the best chilling time?
Let it chill for at least two hours so the layers can firm up a bit and the tastes mix together perfectly.
- → What can I use instead of Heath toffee?
You can swap it out for crushed cookies, chopped Snickers, or KitKat for similar crunch and sweetness.
- → How do I keep the cake from being too soggy?
Let the cake cool a little before adding the condensed milk. This makes sure it soaks in evenly and doesn’t get overly wet.
- → Can I assemble it early?
Yes, you can prepare it a day ahead. Keep it chilled in the fridge, but save the Heath bar topping for just before serving so it stays crisp.
