These easy healthy flapjacks are soft, chewy and packed with dried fruit and nuts for a satisfying texture. They make a simple, homemade granola bar that’s a great snack or breakfast-on-the-go.
These flapjacks (also known as granola bars) are a lighter adaptation of a popular chocolate flapjack recipe. If you prefer cookies made with oats, try a chewy oat and raisin cookie instead.
⭐️ Why this recipe works
- Wholesome ingredients: Jumbo rolled oats and a mixed trail mix give great texture, fibre and lasting energy, making these flapjacks a healthier snack choice.
- Customisable sweetness: Adjust the golden syrup to control sweetness and chewiness so you get the texture you prefer.
- Flexible substitutions: Easily swap golden syrup for honey or maple syrup, and use any dried fruit and nut mix to suit dietary needs.
- Quick and simple: The method is straightforward and uses everyday pantry staples, so you can make a batch quickly for busy days.

👩🏻🍳 Here’s how to make it
Chewy flapjacks recipe step-by-step
- Preparation
- Line a 20cm (8-inch) square baking tin with non-stick baking paper.
- Preheat the oven to 160ºC (320ºF).
- Combine wet ingredients
- Gently heat the butter, light brown sugar and golden syrup (or honey) in a saucepan. Stir over low heat until melted and well combined.
- Mix in oats and trail mix
- Add the jumbo rolled oats to the saucepan and stir until every oat is coated in the buttery syrup.
- Stir in the trail mix or your chosen dried fruit and nuts until evenly distributed.
- Shape and bake
- Press the mixture firmly into the prepared tin, compacting it into the corners so the bars hold together when cut.
- Bake at 160ºC until the top is golden and the edges are set but the middle still looks slightly soft—about 15–20 minutes.
- Cool and slice
- Allow the flapjacks to cool completely in the tin so they can set. Chilling in the fridge overnight helps if you need very clean cuts.
- Once cool, use a sharp knife to slice into 16 squares.
📖 Variations
- These flapjacks are easily tailored to your needs and tastes.
- Vegan/dairy-free: Use a non-dairy butter or margarine in place of butter.
- Gluten-free: Use certified gluten-free oats for those avoiding gluten.
- Honey alternative: If swapping golden syrup for honey, add a tablespoon of nut butter (like peanut butter) to help bind the oats.
- Flavour ideas: Add cinnamon, mixed spice, or swap the trail mix for apricots and almonds for a different twist.
🍯 Storing and reheating leftovers
- Room temperature: Store in an airtight container for up to 5 days. Layer with parchment paper to prevent sticking.
- Fridge: Keeps up to 10 days in an airtight container; bring to room temperature before serving for best texture.
- Freezer: Freeze slices wrapped individually or flash-freeze on a tray, then transfer to a freezer-safe bag. Thaw at room temperature or in the fridge.
💡 Chef’s Guide: Expert Tips
From test kitchens and professional experience, here are practical tips to get great results every time.
- Low and slow: Bake at 160ºC to retain a soft, chewy texture; higher heat will dry them out.
- Line the tin: Use baking paper so the flapjacks lift out easily and don’t stick.
- Don’t overbake: Remove while the centre still looks slightly soft—the bars will firm up as they cool.
- Press firmly: Compact the mixture into the tin to avoid crumbly bars when cut.
- Cool fully before cutting: For clean squares, let them set completely, or chill briefly in the fridge.
❓FAQs
Cool them fully in the tin, or chill overnight in the fridge, then cut with a clean serrated or sharp knife to avoid crumbling.
Stored in an airtight container, they keep about a week at room temperature or in the fridge; they also freeze well for longer storage.
Oats and less-refined sweeteners make flapjacks a generally healthier option than many cakes, but they’re still a treat—portion control matters.
Overbaking or using quicker-cooking oats can make them crumbly. Use jumbo rolled oats and bake at a lower temperature to keep them moist and chewy.

Easy Healthy Flapjacks
Ingredients
- 315 g (3 2/3 cups) jumbo rolled oats
- 150 g butter
- 150 g light brown sugar
- 3–4 tablespoons golden syrup (see notes)
- 125 g trail mix (dried fruit and nuts)
- 1 teaspoon vanilla extract (optional)
Instructions
- Preheat oven to 160ºC and line a 22cm (9×9 inch) square tin. An 8-inch (20cm) tin works too; add 2–5 minutes to baking time if using the smaller tin.
- Weigh the butter, golden syrup and brown sugar into a saucepan. Heat gently until melted, whisking to combine.
- Pour the butter-syrup mixture over the oats and mix well. Stir in the trail mix until evenly distributed.
- Press the mixture firmly into the prepared tin. Bake for 15–20 minutes until the top is golden and the edges are set but the centre remains slightly soft.
- Allow to cool completely in the tin, then cut into 16 squares.
Notes
- The amount of golden syrup determines how soft the bars are—use more for a softer result.
- Honey or maple syrup can replace golden syrup; add a spoonful of nut butter if using honey to help bind the oats.
- Any dried fruit and nut mix can be used instead of the trail mix.
- Rolled oats give a chewy bar; fast-cooking oats will make the bars more crumbly.
- Store in an airtight container for up to one week at room temperature or in the fridge.
