Flapjacks are a popular British sweet treat traditionally made with oats and golden syrup. Similar to homemade granola bars, muesli slice or ANZAC slice, flapjacks are baked to perfection with just the right amount of crunch and chewiness!

My flapjacks are made using just 5 traditional ingredients.. BUT with the addition of a layer of chocolate on top! YASSS!

Flapjacks are often served with a cold glass of milk or a cup of tea or coffee, but they're also delicious as a quick snack or in school lunch boxes.

What You Need

Just 5 basic ingredients is all it takes to make these oaty, chewy, caramel flavoured flapjacks with chocolate on top!

Note: Please scroll to the recipe card at the bottom for ingredient quantities and the full detailed method.

• Butter - I use unsalted butter in this recipe, however if you are using salted butter, just omit the pinch of salt.
• Brown Sugar - use regular brown sugar or dark brown sugar.
• Golden Syrup - works best for this recipe however you can substitute with maple syrup, corn syrup or honey if you can't find golden syrup, or you can make your own.
• Quick Oats - are best for this recipe as they hold the slice better than regular old fashioned rolled oats.
• Milk Chocolate - use a good quality milk chocolate such as Cadbury or Nestle. You can substitute milk chocolate with white or dark chocolate if preferred.
• Coconut Oil (optional) - this is optional but it helps to stop the chocolate layer from cracking when cut.

Equipment Required

You will need a microwave, stove-top or Thermomix for melting the ingredients.

You will also need a 20cm (8 inch) square baking tin and an oven.

I specify fan-forced oven temperatures in my recipes. If using a conventional oven, increase the temperature by 10-20 degrees celsius.

Step By Step Instructions

10 minutes prep time and 5 simple steps is all it takes to make chocolate flapjacks!

Note: Please scroll to the recipe card at the bottom of the post for ingredient quantities and the full detailed method.

Step 1 - Preheat Oven And Prep The Baking Pan

Preheat the oven to 150 degrees celsius (fan-forced).

Grease and line a 20cm (8 inch) square cake tin with baking paper. Set aside.

Step 2 - Combine The Ingredients

Place the butter, golden syrup, brown sugar (and salt, if using) into a microwave-safe bowl. Melt on 50% power for 4 minutes (stirring every minute).

Step 3 - Add The Oats

Add the quick oats to the bowl and stir until all of the oats are coated in the golden syrup mixture.

Step 4 - Bake

Press the mixture firmly into the prepared baking tin.

Bake for 30 minutes or until golden on top.

Note: the mixture will still be soft, however, it will firm up as it cools.

Allow to cool completely.

Step 5 - Add The Chocolate Topping

Place the milk chocolate and coconut oil (optional) into a microwave-safe bowl. Melt for 3 minutes, 50% power, or until just melted (stirring every 30 seconds).

Pour the melted chocolate over the slice. Place into the fridge for a minimum of 1 hour before cutting into pieces.

Expert Tips

• If you don't have a microwave, you can melt the butter, golden syrup, brown sugar, and salt in a saucepan over low heat.
• If you want an extra chocolatey treat, add some chocolate chips to the mixture before pressing it into the tin.
• These flapjacks are best stored in an airtight container in the fridge for up to 2 weeks. Storing them in the fridge will keep the flapjacks super chewy and crunchy.
• Flapjacks can also be frozen for up to 3 months.
• Add extra toppings like chopped nuts or shredded coconut.
• You could also use dark chocolate or white chocolate in place of the milk chocolate.
