Tim Tam Slam Cake created in the honour of the Tim Tam Slam. Coffee sponge cake filled and topped with Tim Tam spread. Decorated with more of those biscuits you love, Tim Tams!
Every Aussie knows how to do the Tim Tam Slam. Unlike doing the mashed potato, it’s not a dance.
With Tim Tam and a hot beverage in hand is how you do the Tim Tam Slam. For me it is generally coffee, but you may prefer a hot chocolate or warm malted milk.
Bite one end off of your Tim Tam, then bite the other end off. Place one bitten end of your Tim Tam in your drink and suck like it’s a straw.
The about to fall apart Tim Tam is then stuffed in your gob and devoured with glee. Warm coffee soaked chocolate biscuit with a melting chocolate butter cream centre. Who doesn’t love a coffee and chocolate combination?
Those flavours are the base of the cake. Coffee sponge is filled with Tim Tam spread (Tim Tam butter), which I shared on Belly Rumbles earlier this week. The Tim Tam Spread has a chocolate ganache quality, which makes it perfect for cakes.
This cake is the reason to make a batch of Tim Tam spread this Australia Day long weekend. My Cheeselova and White Chocolate Mango Cheesecake are perfect desserts when entertaining, but the Tim Tam Slam Cake would have to be the “Aussiest” of my dessert recipes. Of course, there is the Vegemite Ice Cream recipe …
Recipe Pressure Points
Don’t overcook your coffee sponge cakes. They will take 20 minutes in the oven max. Test with a skewer at the 15 minute mark. Bake them on the same shelf, the tin size you use will allow this in a standard oven.
If you have made the Tim Tam Spread for your filling the day before. Take it out of the fridge at least 20 minutes before filling the cake.
Use a piping bag to squeeze the filling on to the coffee sponge, it will make your life so much easier. Use an offset spatula that has been dipped in boiling and dried well to smooth the filling out evenly.
Special equipment for this recipe
You will need two 18cm (7 inch) round sandwich tins with loose bases.
Special Ingredients for this Recipe
You will need to make a batch of my Tim Tam Spread (Tim Tam Butter). One batch will be enough to fill and ice the cake, with a little left over to enjoy other ways.
What to do with any leftovers
Wrap any leftover cake well in cling wrap and store in the fridge. The cake will last a couple of days but is best to eat on the day (or the day after) of making.
As you can see from the photos I added a smattering of white pearl sugar balls and edible stars. I felt the chocolate on chocolate needed lifting a little.

Important to note that this recipe and the Tim Tam Spread have not been made in conjunction with Arnott’s Biscuits (the manufacturers of Tim Tams). I simply had a Tim Tam recipe development fetish last week, which timed perfectly for Australia day.
Tim Tam Slam Cake
- 170 grams (¾ cup) golden caster sugar/raw caster sugar (superfine sugar)
- 170 grams butter
- 3 eggs
- 170 grams (1 cup) plain flour, sifted
- 3 teaspoons baking powder, sifted
- 2 tablespoons instant coffee (disolved in 1 tablespoon of boiling water)
- 1 quantity Tim Tam Spread (Tim Tam Butter)
- Extra Tim Tams to decorate
- Pre-heat oven 160 Deg C (320 Deg F).
- Grease 2 x 18cm (7 inch) round loose base sandwich tins and line with baking paper.
- Add sugar and butter to the bowl of a stand mixer, or place in a large bowl if using electric beaters. Whisk until mixture is pale and fluffy.
- Add egg with 1 tablespoon of flour. Whisk well an then repeat with the rest of the eggs.
- Once the eggs have been fully combined into the butter mixture fold through the rest of the flour and baking powder. Do not over mix, fold through until just combined.
- Add the dissolved instant coffee and gently fold through the mixture. Again do not over fold. If the cake has a little bit of a coffee swirl happening, it's all good.
- Divide the cake batter between the two prepared sandwich tins. Smooth the tops of the batter gently.
- Place tins in the oven and bake for 20 minutes or until cooked through. Insert a skewer in the middle and if it comes out clean the cakes are cooked.
- Leave to cool in tins for five minutes and then turn out on wire racks to finish cooling.
- Once the coffee sponges have completely cooled fill and ice with Tim Tam spread. Decorate with extra Tim Tams.
- Best served immediately. Store covered with cling wrap in the fridge.
