Gluten Free Millionaires’ Flapjack

The basics

Preparation Time: 1 hour 15 mins

Cooking Time: 35 mins

Serves/Makes: 16 squares


For the oaty base & chocolate topping

175g Delicious Alchemy Gluten Free Oats
85g butter or dairy free alternative, plus extra for greasing
1 tablespoon (20g) golden syrup
50g golden caster sugar
200g gluten free / dairy free dark chocolate
2 teaspoons sunflower oil

For the caramel filling

225g granulated sugar
230g golden syrup
100g butter or dairy free alternative
1-2 teaspoons vanilla extract
250ml cream or soya cream

OR, if you don’t want to make it from scratch then buy 397g can set caramel (e.g. Carnation Caramel). NB. Gluten free only.


Step 1 – make the base

Preheat the oven to 150°C / Fan 130°C.  Grease and line the base and sides of a 20cm (8 inch) square baking tin with greaseproof paper. Melt the butter (or dairy free alternative) in a pan over a low heat. Add the golden syrup and sugar to the butter and heat gently. Once the sugar has dissolved and the butter has melted, remove the pan from the heat and stir in the porridge oats until evenly coated in the syrupy mixture. Pack the mixture into the baking tin and press down firmly into an even layer. Bake in the oven for 35 minutes.

Step 2 – make the caramel

To make the caramel, melt the sugar, syrup and butter (or dairy free alternative) in a pan over a gentle heat. Stir until the sugar has dissolved then add the vanilla extract and cream or soya cream. Turn up the heat slightly and watch the mixture begin to thicken and turn a rich golden colour, (approximately 12-15 minutes) remove from the heat and pour over the flapjack base. Leave to set.

Tip: To test whether the caramel is thick enough, drizzle a small amount on to a side plate. If it begins to firm up, then it is ready.

Step 3

Meanwhile, melt the chocolate in a heatproof bowl over simmering water and stir in the oil (this helps to prevent it from setting completely solid) and pour it over the caramel topping. Smooth into an even layer and gently shake the pan to settle.

Step 4

Leave to cool and set for around 4-6 hours before removing from the pan. Warm a knife with boiling water to get a clean line when slicing.
