Beyond the Lamington: My New Favourite Spicy Aussie Dessert (A Davidson Plum & Pepperberry Crumble)

I’ve been on a bit of a spicy dessert kick lately. It all started when I discovered the mind-blowing idea of a Classic Lamington with a Chilli Jam filling. That sweet-and-spicy combo completely rewired my brain, and it got me thinking: what else am I missing out on?

I’ve always loved cooking with Aussie native ingredients, but I usually stick to the savoury stuff—a bit of lemon myrtle on chicken, some wattleseed in a damper. I never really thought to put them in a dessert, especially not the spicy ones.

That's until I stumbled across two ingredients that have completely changed my winter baking: Davidson Plums and Tasmanian Pepperberry.

If you haven't cooked with them, you are in for a treat.

My New Favourite Ingredients

First, the Davidson Plum. Forget any plum you've had before. These native Australian fruits are a stunning deep purple and are intensely, eye-wateringly sour. Seriously, eating one raw is an... experience. But that powerful tartness is exactly what makes them a superstar ingredient for cooking, because they hold their own against sugar, a bit like a rhubarb or a sour cherry.

Second, the Tasmanian Pepperberry (or Mountain Pepper). This is where the magic happens. These little berries are Australia's native pepper, but they're so much more interesting than the standard black peppercorn. They have a sweet, fruity flavour at first, and then a slow-building, tingly heat creeps up on you. It's not a "blow your head off" chilli spice, but a warm, complex, "what is that?" kind of kick.

The idea hit me: a classic, comforting apple crumble.

The sour Davidson Plums would be perfect with the sweet apples. And that spicy, fruity Pepperberry? I knew it had to go in the crumble topping.

The Experiment: A Crumble with a Secret

I wanted to keep the recipe simple, to really let the native flavours shine. A classic crumble is one of the most iconic desserts for a reason—it’s pure comfort in a bowl. This version just adds a little Aussie surprise.

My Davidson Plum & Pepperberry Crumble Recipe

This recipe is super forgiving, so feel free to play around with it.

What You'll Need:

For the Fruity Filling:

• 4-5 large Apples (like Granny Smith), peeled and chopped
• 1 cup Davidson Plums, chopped (You can often find these frozen, which is perfect)
• 2-3 tablespoons Caster Sugar (more if you like it sweeter)
• 1 tablespoon Cornflour (to thicken the juices)

For the Spicy Crumble Topping:

• 1 cup Plain Flour
• 1 cup Rolled Oats (the old-fashioned kind)
• ½ cup Brown Sugar, packed
• 150g Cold Butter, cubed
• 1-2 teaspoons Tasmanian Pepperberry, ground (Start with 1 tsp; you can always add more!)
• Optional: ½ cup chopped walnuts or pecans for extra crunch

My Simple Method:

1. Prep the Filling: First, preheat your oven to 180°C (350°F). In a large bowl, toss your chopped apples, Davidson plums, caster sugar, and cornflour together until everything is lightly coated. Tumble this mix into a medium-sized baking dish and spread it out evenly.
2. Make the Topping (The Fun Part): In a separate bowl, mix the flour, oats, brown sugar, and your ground Tasmanian Pepperberry. Now, add the cold, cubed butter. Using your fingertips, rub the butter into the flour mixture. You're looking for a shaggy, lumpy texture, like coarse breadcrumbs. Don't overthink it; lumpy is good! Stir in the nuts here if you're using them.
3. Assemble and Bake: Sprinkle that gorgeous, spicy crumble topping all over the fruit. Don't press it down; keep it light and airy. Bake for 35-45 minutes, or until the top is golden brown and you can see the delicious, purple fruit juices bubbling up around the edges.

The Verdict

The smell from the oven is incredible—sweet, fruity, and just a tiny bit spicy.

And the taste? It's everything you want in a crumble. It's sweet and comforting from the apples and oat topping, but then you get the amazing zing from the tart plums. And just as you're thinking about that, the warm, tingly heat from the pepperberry comes through. It's not "hot," it's just warm, and it makes the entire dessert feel more alive.

Served with a big scoop of vanilla bean ice cream... it's just magic.

It's proof that our native ingredients aren't just for fancy restaurants; they can be the secret weapon in our most-loved, iconic desserts.
