Ingredients and substitutions for Ginger Crunch Slice
- Plain flour: Plain or all purpose works best here for a nice shortbread base. You could replace with bread flour in equal measure, if that’s all you have on hand. It is not recommended to use cake flour as this would be too fine and wouldn’t give our base a firm texture.
- Butter: Room temperature unsalted butter is used here, though salted butter would also work if that’s what you have on hand. Room temperature is best because it creates the right texture in the shortbread base whilst it mekts and blends with the topping ingredients best from room temperature.
- Golden syrup: The essential syrup needed to make these the traditional way. It adds a perfect flavor, though can be replaced with honey, agave syrup or brown rice syrup, if you prefer though.
- Sugar: Confectioners or icing sugar dissolves into the topping and balancing out the spiciness of the ginger whilst also helping the filling set perfectly. It's not recommended to replace with any other sugar here as it could likely change the final texture of the slice.
- Ground ginger: The ground ginger gives this the perfect amount of spiciness for a real kick. Smell your ground ginger to ensure it’s still at its peak as it loses aroma and strength after 2 years. Crystallized ginger adds crunch and textural difference, though this is optional.

- 87 grams / ¼ cup golden syrup
- 280 grams / 2 ½ cups confectioner’s/powdered sugar
- ¼ teaspoon sea salt
- 6 grams / 1 tablespoon + 1 teaspoon ground ginger
- Optional: Crystallized ginger to finish
Instructions
Shortbread base
- Preheat the oven to 180ºC/350F and line a 18×18 cm or 7×7 inch square baking tin with parchment paper.
- Place the flour and butter into a bowl and beat on low until the mixture looks like a rough crumble and no piece of butter is larger than a pea.
- Spoon into your baking dish and press firmly until even.
- Place in the oven and bake for 10 minutes or until ever so slightly golden.
Ginger topping
- Toss all the ingredients (except the crystallized ginger, if using) into a saucepan on low heat and stir until the butter has melted and the mixture is bubbling at the edges.
- Pour over your base evenly and press the optional crystallized ginger into the top evenly to your liking.
- Allow to set at room temperature for at least 1 hour, you’ll know it’s completely set when it’s matte and has no movement when you move the tin.

Notes
- Ground ginger: The ground ginger gives this the perfect amount of spiciness for a real kick. Smell your ground ginger to ensure it’s still at its peak as it loses aroma and strength after 2 years. Crystallized ginger adds crunch and textural difference, though this is optional.
- Baking tin: A square baking tin works well here, though a rectangle tin would also work well. Note, the larger the tin from the one used here, the thinner your base and icing will be.
- Best stored: In an airtight container for up to 5 days at room temperature.
- Can be frozen: Simply place into an airtight container and freeze for up to 3 months. Simply defrost at room temperature to enjoy.
