British Flapjack Recipe

Flapjacks, a beloved British favourite, are incredibly easy to prepare with just four ingredients (salt optional), and they’re ready in 30 minutes or less.

There are numerous flapjack recipes available online, including both British and American. American flapjacks differ as they are typically thin, round, and cooked on a griddle or skillet and served with various toppings such as syrup, butter, fruit, or even chocolate chips. To us Brits, this would be more commonly known as a ‘pancake’. (Let’s not get started on our pancakes too, which an American would more commonly known as a Crepe). Still with me? 🤪

OK, back to flapjacks, our British flapjacks are sweet oat bars made with rolled oats, butter, sugar, and golden syrup. They are baked in a square or rectangular tray, cooled, and then cut into bars or squares. British flapjacks have a chewy texture and are more similar to granola or oat bars.

All the flapjack recipes online I’ve tried are missing something – either too dry, with no syrup or butter flavour. As a typical flapjack-loving Brit, I created a recipe that perfectly balances indulgence and flavour. This flapjack recipe has the perfect balance of golden syrup and a super delicious butter flavour.

These flapjacks also don’t require any fancy mixers or tools; a simple wooden spoon and a bowl will do the job. And if you measure in grams like I do, it’s a one-bowl recipe.

Plus, I’ve provided two methods for preparation:

  • Either on the stovetop,
  • Or in the microwave (fastest).

These versatile treats are perfect for satisfying your sweet tooth or enjoying as a tasty breakfast option.

History of a Flapjack

Flapjacks have a humble history. Originating in the British Isles, they were traditionally made using oats, butter, and some form of syrup or honey, offering a simple and energy-rich snack for labourers. Over time, they gained popularity as a treat enjoyed by all, with variations emerging, such as the addition of golden syrup or dried fruits.

Today, flapjacks remain a beloved comfort food and are enjoyed not only in the UK but also around the world for their delicious, chewy, and satisfying qualities.

Yield: 8-inch pan (16 servings)

British Flapjacks

British Flapjacks
Prep Time 10 minutes
Cook Time 25 minutes
Total Time 35 minutes


  • 200g (2 cups) rolled oats
  • 115g (½ cup) unsalted butter (or salted butter and omit additional salt)
  • 100g (½ cup) brown sugar
  • 4 tablespoons (80g) golden syrup, see notes
  • (optional) pinch of salt


    1. Preheat your oven to 160°C (325°F). Grease and line a 9x9-inch (23x23cm) square baking pan with parchment paper allowing an overhang for easy removal.
    2. In a saucepan or microwave-safe bowl, melt the butter, brown sugar, and golden syrup over low heat (saucepan) or in the microwave in 30-second increments, stirring between each, until the mixture is fully melted and well combined.
    3. Remove the saucepan or bowl from the heat/microwave and stir in the rolled oats and a pinch of salt until well combined.
    4. Transfer the mixture to the prepared baking pan, pressing it down evenly with a spatula or the back of a spoon.
    5. Bake in the preheated oven for approximately 25-30 minutes or until the flapjacks turn golden brown around the edges.
    6. Remove from the oven and let them cool in the pan for about 10 minutes. While still warm, use a sharp knife to cut them into squares or rectangles, then allow them to cool completely in the pan.


Rolled Oats:

Ensure that you're using the correct type of oats. The old-fashioned 'rolled oats' is the type you need, not the instant or quick oats type.

Golden Syrup:

If you don't have access to golden syrup, you can use one of the following substitutes:

  • Corn Syrup: Light corn syrup can be used as a replacement for golden syrup. It has a similar consistency and sweetness. However, keep in mind that it might not provide the same flavour profile as golden syrup.
  • Maple Syrup: Pure maple syrup can be used as an alternative, but it will impart a distinct maple flavour to your flapjacks. If you enjoy the taste of maple, this can be a delicious substitution.
  • Honey: Honey can also be used instead of golden syrup. It has a natural sweetness and can add a unique flavour to your flapjacks. Note that honey has a stronger flavour than golden syrup, so your flapjacks may taste slightly different.
  • Agave Nectar: Agave nectar is another sweet syrup that can replace golden syrup. It has a mild flavour and is often used as a healthier alternative to other sweeteners.

Storing Flapjacks

Store leftover flapjacks in an airtight container at room temperature for up to a week, or in the refrigerator for up to two weeks. For longer storage, see the guide on how to freeze and thaw flapjacks.
