Our millionaire flapjacks have a chewy oat base and then a layer of gooey caramel and chocolate to replicate the flavours of a millionaire’s shortbread.
A classic flapjack recipe is already an indulgent afternoon treat, but this recipe takes the British favourite to new heights. We’ve replicated the popular flavours of millionaire’s shortbread and combined it with a delicious flapjack base. We’ve made the caramel but if you’re short on time use a shop-bought tin.
- 150g butter
- 125g light muscovado sugar
- 1tbsp golden syrup
- 225g jumbo oats
For the caramel:
- 125g butter
- 397g can condensed milk
- 90g golden syrup
- 1tbsp vanilla extract
For the topping:
- 150g milk chocolate, broken
- 150g plain chocolate, broken
- 1tbsp sunflower oil
- 90g white chocolate
- 2tbsp freeze dried raspberries
- Grease and line a 18cm x 28cm tin, or use one as close to this size as possible. Heat oven to 200C (180C fan, Gas 6).
- Heat the butter, sugar and syrup in a pan and stir until melted.
- Stir in the oats, then dollop the mixture into the prepared tin. Bake for 15 minutes until golden.
- Combine the butter, condensed milk, golden syrup and vanilla in a non-stick pan. Heat gently, stirring all the time until the mixture thickens slightly and turns golden brown. Pour on top of the flapjack mixture, spreading over evenly. Cool in the fridge until firm.
- Melt the milk and plain chocolate with the oil in a bowl, resting over a pan of simmering water. Pour on top of the caramel layer. You could also melt the chocolate in the microwave.
- Melt the white chocolate in the same way. Spoon into a plastic piping bag, leave for 5 mins to firm up slightly. Snip off the end and randomly drizzle the white chocolate over the top. Sprinkle over the freeze dried raspberries. Leave to set in the fridge, once firm cut into bars, to serve.
Top tips for making Millionaire flapjacks
Make your millionaire flapjacks look professional by following our tips on how to decorate and cut them. We also have guidance on how to freeze any leftovers to stop them from going to waste.
Can you freeze millionaire flapjacks?
For best results, eat the millionaire flapjacks when they are fresh and store at room temperature in an airtight container. However, if you have lots leftover and you don’t want them to go to waste.
Wrap the portions tightly in clingfilm to protect them from freezer burn. Defrost in the fridge before enjoying. It’s best to consume within three months.
How do I cut millionaire flapjacks into neat bars?
Similar to when you slice millionaire shortbread, you should use a sharp knife. You can also dip it in water between cuts to help make the process easier. Make sure you wipe the knife with a cloth after dipping in the hot water to ensure no water gets on your bake.
Once cut you could package them up as an edible gift for a loved one, new neighbour or for a friend that doesn’t like birthday cake.
How to feather chocolate?
Traditionally millionaire shortbread is decorated with a layer of chocolate that has a feathered pattern. This is achieved by drizzling lines of a light coloured chocolate on a darker-coloured chocolate base. Then use a toothpick or the tip of a sharp knife to drag through the lines and create the feathered finish.
In step four of this recipe, you make caramel. Using a non-stick pan will make cleaning much easier but it’s also important to use a light coloured pan, such as stainless steel, so you can easily identify the caramel colour change and know when it’s ready. Food writer Jessica Ransom highly recommends the Le Creuset 3-Ply Stainless Steel Lidded Saucepan.

This pan is available in 18cm and 20cm sizes if you need something bigger. It is made from stainless steel which looks timeless and chic in any kitchen. The saucepan comes with a lid which is useful when boiling vegetables and you want to speed up the process of the water getting hot enough.
Although it isn’t non-stick, it’s still an ideal pan for making caramel as you can easily see when the colour has changed. The best way to clean a pan after making caramel is to fill it with water and warm it over a gentle heat to dissolve any residual sugar in the pan.
