The Viral Tim Tam Tray Hack: 4-Ingredient Rocky Road Slice

If you have spent five minutes scrolling through TikTok or Instagram reels lately, you’ve definitely seen the Viral Tim Tam Tray Hack. It is the ultimate “lazy” dessert trend that completely breaks all the baking rules. Instead of using a baking tin, you use the plastic Tim Tam tray as the actual slice mould.

Today, we are making the absolute best version of this internet sensation: Tim Tam Rocky Road Slice loaded with rich melted milk chocolate, fluffy mini marshmallows, and shredded coconut. It takes less than 5 minutes of hands-on prep, requires just 4 ingredients, and delivers an insanely decadent treat. Let’s make it!


INGREDIENTS

1 packet Arnott’s Tim Tam biscuits (whichever flavour you like!)
300-350 grams Milk Chocolate
1/2 cup Mini Marshmallows
1/4 cup Shredded or Flaked Coconut


METHOD

Step 1: Open your packet of Tim Tams and carefully slide out the plastic tray. Leave the biscuits sitting perfectly in their designated little slots.

Step 2: Melt your chocolate in the microwave in 30-second bursts until it’s perfectly pourable.

Step 3: Pour the warm liquid chocolate straight over the Tim Tams. Make sure to fill all the cracks, gaps, and crevices between the biscuits so everything fuses together.

Step 4: Tap Out the air bubbles – Pick up the plastic tray and firmly tap or bang it down on your kitchen bench a few times. This forces any air bubbles to the surface so you don’t get any hollow air pockets.

Step 5: Load It Up! While the chocolate layer is still warm and sticky, it’s time to turn it into rocky road. Scatter your mini marshmallows and shredded coconut generously over the top. Press them down very gently into the chocolate so they stick.

Step 6: Chill and Serve – Pop your loaded tray into the fridge and let it chill until set. 30 minutes in the fridge will be plenty! Once set, pull the plastic tray gently from each side to release the Tim Tam slice. Slice it right down the middle to reveal those epic Tim Tam cross-sections, then cut into bite-sized squares!

OTHER VARIATIONS??
Get Creative! You can use this same tray hack method with any flavour combo. Just grab your pack of Tim Tams, and then select some toppings to enjoy.

Some examples I have tried include Chewy Caramel Tim Tams with crushed up honeycomb and white chocolate, and mint Tim Tams with Peppermint Crisp and Mint Aero on top! This is your slice – anything goes!
