Ingredients for this British Flapjacks Recipe
- 2 cups (180g) rolled oats
- ½ cup (115g) unsalted butter
- ½ cup (120ml) golden syrup (or honey/maple syrup as an alternative)
- ½ cup (100g) brown sugar
- ¼ cup (40g) dried cranberries or raisins
- 2 tbsp pumpkin seeds or sunflower seeds (optional)
- A pinch of salt
- ½ tsp ground cinnamon (optional for a warm flavor twist)

Step 1: Prepare the Baking Tin
Preheat your oven to 350°F (175°C). Line an 8-inch square baking tin with parchment paper, making sure it covers the sides as well for easy removal. Lightly grease the paper to prevent sticking.
Step 2: Melt the Butter Mixture
In a medium saucepan over low heat, combine the butter, brown sugar, and golden syrup. Stir gently until everything melts together and the mixture becomes smooth and glossy. Remove from the heat once fully blended.
Step 3: Combine with Dry Ingredients
In a large mixing bowl, pour the melted butter mixture over the rolled oats. Add a pinch of salt, cinnamon (if using), and mix thoroughly until the oats are well coated. Stir in the dried cranberries and seeds, making sure they’re evenly distributed.
Step 4: Press Into the Tin
Spoon the mixture into your prepared tin. Use the back of a spoon or a spatula to firmly press the mixture down into an even layer. Compacting it well helps hold the flapjacks together after baking.
Step 5: Bake to Perfection
Place the tin in the preheated oven and bake for 20–25 minutes, or until the edges turn golden brown. For chewier flapjacks, bake closer to 20 minutes; for a crunchier result, let them go a little longer.
Step 6: Cool and Slice
Remove the tin from the oven and allow it to cool for about 10 minutes. While still slightly warm, cut into bars or squares—but leave them in the tin to cool completely before lifting out. This prevents crumbling and ensures clean edges.

Frequently Asked Questions
1. Can I use honey instead of golden syrup?
Yes, honey is a common substitute. It gives a slightly different flavor but works just as well to bind the oats.
2. Are flapjacks gluten-free?
They can be! Use certified gluten-free oats and check that all added ingredients are gluten-free.
3. Why did my flapjacks fall apart?
This usually happens if the mixture wasn’t pressed down firmly enough, or if they were cut while still warm. Be sure to let them cool completely.
4. Can I reduce the sugar content?
Yes, you can cut down the brown sugar slightly or replace it with coconut sugar or a natural alternative, though the texture may change a bit.
5. What other ingredients can I mix in?
Try chocolate chips, chopped nuts, shredded coconut, or dried apricots. Just keep the total mix-in volume around ½ cup to avoid compromising texture.
6. Do I need to refrigerate flapjacks?
Not necessarily. They stay fresh at room temperature, but refrigeration can extend shelf life, especially in warmer climates.
7. Can I make these vegan?
Absolutely. Use a plant-based butter and maple syrup or agave in place of golden syrup or honey.
8. How do I get clean slices?
Use a sharp knife and cut while they’re still a little warm, then leave them in the tin to cool completely before removing.
