If you have ever visited a country Women's Weekly baking competition or regional Australian bakery, chances are you have encountered the formidable Lumberjack Cake. Born as a hearty, nutrient-rich cake to keep timber cutters energized through arduous physical labour, this recipe has stood the test of generations for one simple reason: it is quite simply one of the moistest cakes on the planet.
The secret to its legendary texture is the combination of dates softened in boiling water and bicarbonate of soda alongside freshly grated Granny Smith apples. But the true crowning glory happens during the final 15 minutes of baking, when a rich caramel glaze of butter, brown sugar, milk, and shredded coconut is poured over the cake and broiled until it turns golden, bubbling, and intensely fragrant.

The Chemistry of Bicarb Date Softening
Why do we pour boiling water and bicarbonate of soda over the chopped dates and grated apples? Dried dates possess tough outer pectin skins that resist moisture penetration.
The Alkaline Breakdown Reaction
Bicarbonate of soda creates an alkaline environment that rapidly hydrolyzes date hemicellulose and softens the fruit into a rich, pulpy puree. When combined with natural malic acid from grated apples, it ensures an evenly distributed crumb that retains moisture for days.
Ingredient Selection: Dates, Apples, and Coconut
- Pitted Dates: Medjool or standard pitted dried dates provide deep caramel sweetness and natural moisture.
- Granny Smith Apples: Crisp green apples offer sharp acidity that cuts through the rich dates and sweet coconut.
- Shredded Coconut: Wider coconut shreds produce a distinct, crunchy chewy top layer that caramelizes gorgeously.
- Brown Sugar: Adds deep molasses depth to the broiled coconut topping.
- Unsalted Butter: Used both inside the sponge and in the bubbling topping for supreme richness.
Wholesome Pantry Ingredients: Pitted dates, Granny Smith apples, shredded coconut, butter, flour, and brown sugar
Step-by-Step Baking Method
Soak Dates and Grated Apples
In a heatproof bowl, combine 200g chopped dates, 1 coarsely grated Granny Smith apple, and 1 teaspoon bicarb soda. Pour over 250ml boiling water. Stir and let rest for 15 minutes to soften.
Cream Butter and Fold Batter
Cream 125g softened butter and 150g caster sugar for 3 minutes. Beat in the egg and vanilla. Sift in 225g flour, 1 tsp baking powder, and 1/2 tsp cinnamon. Fold in the cooled date-apple mixture until combined. Pour into a lined 22cm round springform pan.
Initial 45-Minute Bake
Bake at 180°C (160°C fan) for 45 minutes until the cake is set and a skewer comes out clean from the center.
Simmer Topping and Broil
Melt 60g butter, 75g brown sugar, and 60ml milk in a saucepan. Stir in 80g shredded coconut. Spread over the hot baked cake. Return to the oven for 12 to 15 minutes until golden and bubbling.
Mistakes That Ruin Lumberjack Cake
Skipping the Bicarb Soak
Throwing raw chopped dates directly into the batter creates hard, dry date nuggets rather than a uniform, moist crumb. Never skip soaking with bicarb.
Burning the Coconut Topping
Brown sugar and coconut can go from golden to burnt in minutes. Keep a close eye during the final 12 minutes of baking.
Country Hospitality: Slice into thick wedges and serve warm with double cream or vanilla custard.
Frequently Asked Questions
Why is it called Lumberjack Cake? +
The cake originated as a hearty, energy-dense country bake packed with dried fruits, apples, and butter to sustain forestry workers (lumberjacks) during long days in the bush.
What type of apples work best for Lumberjack Cake? +
Granny Smith apples are ideal because their crisp tartness balances the natural sweetness of medjool dates and brown sugar while adding unmatched moisture.
Why do you add bicarbonate of soda to the boiling water and dates? +
Bicarbonate of soda raises the pH of the water, rapidly breaking down the tough cellulose fibers of dried dates so they soften into a jam-like puree that disperses evenly throughout the batter.
Should I use shredded or desiccated coconut for the topping? +
Shredded coconut (wider strands) gives the best chewy, caramelized crust, but standard desiccated coconut also works well.
How long will Lumberjack Cake stay fresh? +
Thanks to the high natural fruit moisture from dates and apples, Lumberjack cake stays extraordinarily moist for up to 5 days stored at room temperature in an airtight container.
Can you freeze Lumberjack Cake? +
Yes, wrap slices or the whole cooled cake in plastic wrap and aluminium foil. Freeze for up to 3 months. Thaw overnight in the fridge and warm slightly before serving.
Why did my coconut topping burn? +
High sugar coconut toppings brown very quickly. Watch the cake closely during the final 12 to 15 minutes of baking, and loosely tent with foil if the coconut browns too fast.
Can I make this cake in a square tin or loaf tin? +
Yes, an 8-inch or 9-inch square cake tin works perfectly. For a loaf tin, extend the initial baking time by 10 minutes.
Can I substitute other dried fruits for dates? +
Dried figs, prunes, or sultanas can be substituted, but traditional pitted dates provide the most authentic caramel flavour and moisture.
Should Lumberjack Cake be served warm or cold? +
It is sensational served warm with a scoop of vanilla bean ice cream or pouring custard, but it slices cleanest when cooled to room temperature.
