World’s Biggest Tim Tam recipe video

homemade tim tam recipe
 

This is the world’s biggest Tim Tam. You can of course scale the Tim Tam recipe down and make normal sized Tim Tams. Or surprise someone who is doing giant things with one like this.

We gave this huge Tim Tam to Jessica Watson, the youngest person to sail solo around the world. She is a delightful young lady and I’m sure you’ll enjoy meeting her in this video.


 
This Tim Tam recipe makes one Tim Tam that is 50cm (19.69 inches) long by 25cm (9.84 inches) wide.
 It weighs a massive 15.3kg (33.73 pounds)!

To make this giant Tim Tam you will need:

Biscuit / cookie part
1150g (40.57 ounces) or 5 ¼ cups sugar
668g (23.56 ounces) or 2 ¾ cups plus 2 Tbsp of brown sugar
433g (15.27 ounces) or 2 cups margarine
320millilitres (10.82 fluid ounces) or 235g (8.29 ounces) vegetable oil
8 eggs
58g (2.05 ounces) or 3 Tbsp golden syrup
2 ¼ tsp baking powder
4 ½ tsp salt
2 Tbsp cocoa powder
1890g (66.67 ounces) or 11 ¾ cups plain or all purpose flour
360g (12.7 ounces) or 3 cups cornflour (cornstarch)

Place the white sugar, the brown sugar, margarine, oil and golden syrup into a large bowl.
Mix it together until it is well combined.

Add in the salt and the eggs and mix it through.

Sift the corn flour, plain flour, baking powder and cocoa powder and mix into the dough.

Divide into four quarters and roll each quarter out between two sheets of baking paper to make a 25 x 25cm (9.84 inches) square, 1cm (0.39 inches) thick.

Slide it onto a baking tray and bake at 150C (302 degrees Fahrenheit) until it is golden and firm to the touch (It took 45 minutes in my oven).

While it is still hot trim it along the edges to make them straight and even.

Tim Tam Filling Recipe
5550g (195.77 ounces) or 44 cups icing (powdered) sugar
3/4 cup or 90g (3.17 ounces) cocoa powder
1 Tbsp salt
2400g (84.66 ounces) or 10¾ cups plus 3 Tbsp of margarine.

Whip it all together until it is smooth and thick.

Chocolate
3500g (123.46 ounces) of chocolate for covering (watch the chocolate secrets video for how to temper chocolate)

    Hi there Ann, Love your videos! I am from Michigan in USA. Ive watched this video alot and never knew what a tim tam was until one day at an amish market where i shop for discounted groceries, i saw some for 1.29 and now i see them for .75 cents and ive even got some for .25 cents!! Absolutly a steal! A few months outdated but still excellent and addicting!! I brought 6 packs to church and they were gone within minutes like less then 10 and there was maybe 12 of us there that night. Anyways, wanna make my own but i was going to use real butter and coconut oil in place of the margarine and vegtable oil. Would that be ok?? Also is the recipe correct that you only used 2 TBSP cocoa for the buscuit?? And also is the filling recipee also correct with 44 cups powdered sugar and 10 & 3/4 c. Margarine?? I was going to half the recipe but thats like bigger then my kitchen im going to be using to mix it and i dont think theres a bowl big enuf to mix it all in? Please let me know asap. Id like to make it asap. Thanks amd God Bless. Hope you have a happy Easter!!

      Hi Melissa Burns, o glad you love Tim Tams. Obviously this recipe is for a giant Tim Tam. And yes the measurements are correct. The small amount of cocoa powder gives it a little more color rather than flavour and you need heaps of filling.

      • Ok, thanks Alot! I will stock up on butter and go get the biggest bowl i can find. I have black cocoa powder i bought from a new amish market i found, i think ill try that.
