Preheat the oven to 285°F (140°C) fan assisted or 320°F (160°C) conventional.
Roughly chop the pecans or place in a food processor and pulse until chopped but still chunky. Place the pecans in a bowl and add the remaining ingredients.
Use your fingers to press the mixture into a medium baking dish (about 8 × 8 inch [20 × 20 cm]); use a silicone baking dish or a regular baking dish lined with parchment paper. Bake for about 25 minutes or until crispy. Remove from the pan and allow to cool slightly. Slice into 8 bars with a greased sharp knife. Store in a sealed container for up to 3 days or freeze for up to 3 months.
