How to Make No-Bake Tim Tam Slice
Step 1: Prepare Your Pan
Start by lining an 8×8-inch baking dish with parchment paper. This little step makes removing and slicing your No-Bake Tim Tam Slice effortless, and you’ll get those gorgeous, clean layers every time.
Step 2: Make the Tim Tam Base
In a big mixing bowl, combine your crushed Tim Tam biscuits, melted butter, condensed milk, cocoa powder, and vanilla extract. Stir everything together until it’s evenly mixed—the mixture should look fudgy but hold together when pressed. Tip it into your prepared dish and press it firmly into an even layer; use the back of a spoon or your fingertips to make sure it’s nice and flat.
Step 3: Melt and Pour the Chocolate Topping
Place the milk chocolate chips and vegetable oil in a microwave-safe bowl. Microwave in 30-second intervals, stirring thoroughly after each until you get a smooth, silky chocolate sauce. Pour this over your biscuit base, gently spreading it with an offset spatula or the back of a spoon to cover edge to edge.
Step 4: Decorate and Chill
For a fun (and delicious) finish, sprinkle extra chopped Tim Tams evenly over the top while the chocolate is still soft. Pop the whole pan into the fridge for at least 3 to 4 hours. This time is crucial—the chocolate needs to set, and the base firms up, giving each slice perfect structure.
Step 5: Slice and Serve
Once completely set, lift the slice out of the pan using the parchment paper edges. Use a sharp knife to cut into 16 squares. For neat edges, wipe the knife clean between cuts. Your No-Bake Tim Tam Slice is officially ready to be devoured!

Garnishes
Presentation is half the fun, especially with a treat as tempting as No-Bake Tim Tam Slice. A scattering of extra chopped Tim Tam biscuits on top adds visual flair and a delightful crunch. For an extra-special look, try a drizzle of melted white chocolate or a dusting of cocoa powder just before serving—both highlight those rich chocolate layers beautifully.
Side Dishes
Though this slice is a standout on its own, you can create a show-stopping dessert platter by pairing it with fresh berries, a scoop of vanilla ice cream, or a simple fruit salad. The bright flavors and chilled creaminess play perfectly off the indulgent richness of the No-Bake Tim Tam Slice.
Creative Ways to Present
For parties, arrange the cut squares on a tiered stand or tuck them into mini cupcake liners for grab-and-go bites. If you’re feeling fancy, stack the slices in a checkerboard pattern or add tiny flags for a festive touch. However you serve it, this No-Bake Tim Tam Slice will always be the star.
Make Ahead and Storage
Storing Leftovers
To keep your No-Bake Tim Tam Slice at its best, store leftovers in an airtight container in the fridge. The chocolate stays glossy and the base remains fudgy for several days. Just remember to separate layers with parchment if stacking to avoid sticking.
Freezing
This recipe freezes beautifully, so it’s a wonderful make-ahead option. Arrange the sliced squares in a single layer (or between sheets of parchment) in a freezer-safe container. They’ll keep for up to 2 months, ready for any last-minute dessert emergency or chocolate craving!
Reheating
While the No-Bake Tim Tam Slice is typically served cold, if you like a softer, gooier texture, let individual pieces rest at room temperature for 10 to 15 minutes before enjoying. Avoid microwaving, as it may melt the topping unevenly and affect that perfect slice.
FAQs
Can I use a different type Dessert
Absolutely! While Tim Tams give this slice its signature flavor, you can substitute with any chocolate cream-filled biscuit or even a mix of chocolate cookies and a few tablespoons of cocoa for a similar result. The key is a biscuit that holds together when crushed and mixed.
Can I make No-Bake Tim Tam Slice with dark chocolate?
Definitely! For a richer, more bittersweet topping, swap half or all of the milk chocolate chips with dark chocolate chips. It balances the sweetness from the condensed milk and gives the slice a more complex flavor profile.
Do I need a food processor to crush the Tim Tams?
No food processor? No problem. Place your Tim Tams in a zip-top bag and crush them with a rolling pin until you achieve fine crumbs. A few larger chunks are fine—they’ll offer a pleasant texture once combined with other ingredients.
How long does No-Bake Tim Tam Slice last in the fridge?
Kept chilled in an airtight container, your No-Bake Tim Tam Slice is best consumed within five days. Past that, it may start to lose its texture and flavor, but chances are it’ll be devoured long before then!
Can I add nuts or other mix-ins to the slice?
Absolutely! For extra crunch, mix in chopped roasted hazelnuts, almonds, or even a handful of mini marshmallows into the base before pressing it into the pan. Just be sure not to overload the mixture, as too many add-ins can make slicing tricky.
