Ingredients

Instructions

  1. Step 1: Preheat oven to 350°F (180°C). In a bowl, whisk together 250 g all-purpose flour, 1 tsp baking powder, 1/4 tsp salt, and 1 tbsp quandong spice blend.
  2. Step 2: In a separate large mixing bowl, beat 2 large eggs with 150 g caster sugar and 1 tsp vanilla extract until pale and fluffy.
  3. Step 3: Slowly add the dry ingredients into the egg mixture, folding gently to combine. Stir in 50 g melted unsalted butter and 100 g toasted macadamia nuts until evenly incorporated.
  4. Step 4: Divide the dough in half and shape each half into a log about 30 cm long and 5 cm wide on a baking sheet lined with parchment paper.
  5. Step 5: Bake logs for 30 minutes until golden and firm to the touch. Remove from oven and let cool for 10 minutes.
  6. Step 6: Using a serrated knife, slice logs diagonally into 1 cm thick biscotti. Arrange slices cut side down on the baking sheet.
  7. Step 7: Bake for an additional 12 minutes, flip biscotti, and bake 10 more minutes until dry and crisp. Cool completely before serving.

Cool fully before storing. Most baked desserts keep at room temperature in an airtight container for 2–3 days, or in the fridge for up to 5 days. Cream- or custard-based desserts must go in the fridge within 2 hours; reheat gently or serve cold per the recipe.

Can I substitute ingredients in Macadamia and Quandong Spice Biscotti?

How do I scale Macadamia and Quandong Spice Biscotti for a different number of people?

The recipe is written for 12 servings. Multiply each ingredient by (your serving target / 12). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
