Chef Tips from the Video

- Grate the zucchini just before incorporating to prevent it from losing moisture
- Toast the hazelnuts 10‑12 minutes at 180 °C for a stronger aroma
Troubleshooting
The brownie is too dry
Check the baking time; reduce to 15‑18 minutes or add 1‑2 tablespoons of applesauce for more moisture.
The centre remains liquid after the stated time
Extend baking by 3‑5 minutes and loosely cover the top with foil to prevent over‑browning.
The brownie crumbles when cutting
Allow it to cool completely (at least 20 minutes) and use a large serrated knife slightly dampened.
Storage
Refrigerator: Store in an airtight container, up to 5 days.
Freezer: Wrap each portion in plastic film then place in a freezer bag, up to 2 months.
Room temperature: At room temperature, up to 2 days, kept away from moisture.
Make-Ahead Tips
- The brownie keeps very well; it can be made the day before and gently reheated before serving
- Portions can be frozen individually for a quick snack
- Pre‑toast the hazelnuts ahead of time to save time
