Gluten-Free Millionaire’s Shortbread
Makes: 16 squares
Prep: 25 minutes
Bake: 25 minutes
Chill: 2–3 hours
Shortbread Base
200g unsalted butter, softened
100g caster sugar
330g gluten-free plain/all-purpose flour blend
Caramel Layer
120g unsalted butter
60g caster sugar
2 tbsp golden syrup
1 × 397g can sweetened condensed milk
Chocolate Topping
200–230g milk chocolate (or half milk, half dark)
Pinch of flaky sea salt (optional)
Method
1. Make the Shortbread
Heat oven to 180°C (160°C fan).
Line a 20–24cm square baking tin with parchment paper.
Beat the butter and sugar until light and creamy.
Mix in the gluten-free flour until a dough forms.
Press evenly into the prepared tin.
Prick with a fork and bake for 20–25 minutes, until lightly golden.
Cool completely. (The Gluten Free Blogger)
2. Make the Caramel
Place the butter, sugar, golden syrup, and condensed milk in a saucepan.
Heat gently until melted.
Bring to a gentle simmer, stirring continuously.
Cook for 8–10 minutes until thickened and golden.
Pour over the cooled shortbread base.
Refrigerate for about 2 hours until set. (BBC Good Food)
3. Add the Chocolate
Melt the chocolate gently in the microwave or over simmering water.
Pour over the caramel and spread evenly.
Sprinkle with flaky sea salt if desired.
Chill for 30–60 minutes until firm.
4. Slice
Allow the tray to sit at room temperature for 10–15 minutes before cutting into squares. This helps prevent the chocolate from cracking. (BBC Good Food)
Tips for Success
Use a 1:1 gluten-free flour blend that contains xanthan gum, or add ¼ tsp xanthan gum if your blend doesn’t include it. (Juvela)
Stir the caramel constantly to prevent burning.
For a richer flavor, use a mix of milk and dark chocolate.
Store in an airtight container in the fridge for up to a week.
The result is a buttery gluten-free shortbread base, a thick caramel center, and a crisp chocolate top—very similar to a homemade Twix bar. (mamaknowsglutenfree.com)
