Banana and Oat Sugar Free Flapjacks with Chia and Almond
If you have been hunting for sugar free flapjacks that actually taste indulgent, this recipe is about to become your new favourite bake. Traditional British flapjacks are loaded with golden syrup and brown sugar, which can send blood sugar levels soaring before mid-morning. This version ditches all of that completely. Instead, ripe bananas and blended medjool dates do the heavy lifting on sweetness, while rolled oats, chia seeds and ground almonds build a bar that is genuinely filling and satisfying. These are brilliant for busy mornings, post-workout snacking or popping into a lunchbox. Adults love them. Kids demolish them. And you will feel good knowing exactly what went into every single bite.
The ingredient list here is short, honest and deliberately chosen. Ripe bananas are the backbone of the sweetness, and the riper they are, the better. Those spotty, almost-too-far bananas that sit sadly on the counter are pure gold in this recipe. Medjool dates are blended into a smooth paste with a splash of boiling water, which gives the flapjacks their deep, caramel-like richness without a single gram of added sugar. Rolled oats provide the classic chewy texture you expect from a proper flapjack, and they bring soluble fibre that supports gut health and keeps you fuller for longer. Chia seeds add a nutritional boost of omega-3 fatty acids and extra fibre, while ground almonds contribute healthy fats and a subtle nuttiness that rounds out the flavour beautifully. Coconut oil replaces butter, keeping these dairy free, and a generous pinch of cinnamon and a little vanilla extract add warmth without any need for sweetener.
The texture of these sugar free flapjacks is soft and chewy in the centre with gently golden edges. They are not as crisp as a traditional flapjack, and that is completely intentional. The banana keeps things moist and the date paste binds everything together so they hold their shape once cooled. Straight from the oven they are a little soft, so patience is key. Let them cool fully in the tin before slicing and they will firm up into satisfying, sliceable bars. Serve them as they are, or top with a thin drizzle of almond butter and a few sliced banana pieces for something that feels a little more special. A cup of strong tea alongside one of these is a very good afternoon.
From a nutritional standpoint, these flapjacks deliver far more than their traditional counterpart. Each bar contains a solid amount of dietary fibre from the oats and chia seeds combined, supporting healthy digestion and helping to sustain energy levels steadily rather than causing a spike and crash. The natural sugars from banana and dates come packaged with fibre and micronutrients, which is a very different picture from refined sugar hitting your bloodstream all at once. These bars are gluten free if you use certified gluten free oats, dairy free, egg free, refined sugar free and vegan. They store well for several days, making batch baking a genuinely practical option for anyone trying to eat more mindfully without spending hours in the kitchen every day.
Ingredients
- 2 large ripe bananas (the spottier the better for natural sweetness)
- 150 g medjool dates (pitted, soaked in 3 tbsp boiling water for 5 minutes)
- 250 g rolled oats (use certified gluten free oats if needed)
- 40 g ground almonds
- 3 tbsp chia seeds
- 3 tbsp coconut oil (melted and slightly cooled)
- 1 tsp ground cinnamon
- 1 tsp vanilla extract
- 1 pinch fine sea salt (enhances all the other flavours)
- 40 g pumpkin seeds (for extra crunch and zinc)
Instructions
- 1
Preheat your oven to 180C fan and line a 20cm square baking tin with baking parchment, leaving a little overhang on the sides so you can lift the flapjack out easily.
Greasing the parchment lightly with a little coconut oil prevents any sticking.
- 2
Place the pitted medjool dates in a small bowl and pour over 3 tablespoons of boiling water. Leave them to soften for 5 minutes, then transfer the dates and all the soaking water to a blender or food processor and blend until you have a smooth, thick paste.
If your blender struggles, add one extra tablespoon of warm water to help it along.
- 3
In a large mixing bowl, mash the ripe bananas thoroughly with a fork until almost completely smooth. A few small lumps are absolutely fine and will not affect the final texture.
- 4
Add the blended date paste to the mashed banana and stir well to combine. Pour in the melted coconut oil and vanilla extract, then stir again until everything is evenly mixed.
Make sure the coconut oil is not piping hot when it goes in, or it can make the mixture too loose.
- 5
Add the rolled oats, ground almonds, chia seeds, cinnamon, sea salt and pumpkin seeds to the bowl. Stir everything together firmly until you have a thick, cohesive mixture that holds together when you press a little between your fingers.
If the mixture feels too wet, add an extra tablespoon of oats. If it feels crumbly and dry, add a teaspoon of water at a time.
- 6
Tip the mixture into the prepared tin and press it down firmly and evenly with the back of a spatula or the bottom of a glass. The more firmly you press, the better the bars will hold together once baked.
Dampening your hands slightly makes pressing the mixture down much easier without it sticking to you.
- 7
Bake in the preheated oven for 22 to 25 minutes until the top is golden and the edges look set. The centre may still feel slightly soft but it will firm up considerably as it cools.
Keep an eye on it from the 20-minute mark as ovens vary and you want golden, not dark brown edges.
- 8
Remove the tin from the oven and use a sharp knife to score through the surface, marking out your 12 bars while the flapjack is still warm and easier to cut. Do not try to lift the bars out yet.
Scoring while warm prevents cracking when you cut all the way through later.
- 9
Leave the flapjack to cool completely in the tin for at least 20 minutes, then lift it out using the parchment overhang and transfer to a chopping board. Cut all the way through the score lines and your bars are ready to serve.

Pro Tips
- ✓
Use the ripest bananas you can find. Black-spotted bananas give the sweetest result with no bitterness.
- ✓
Press the mixture very firmly into the tin. This is the single most important step for bars that do not crumble.
- ✓
Always cool completely before cutting. Cutting too early is the main reason flapjacks fall apart.
- ✓
Toast the oats briefly in a dry pan before mixing for a deeper, nuttier flavour.
- ✓
Store bars individually wrapped in baking parchment so you can grab one easily on busy mornings.
Frequently Asked Questions
Variations
- •
Cocoa and Hazelnut
Add 2 tablespoons of raw cacao powder and replace the pumpkin seeds with roughly chopped hazelnuts for a chocolatey, indulgent-tasting bar that is still completely refined sugar free.
- •
Lemon and Blueberry
Stir in the zest of one lemon and a small handful of dried blueberries to the mixture. The citrus lifts the whole flavour and the berries add little bursts of fruitiness throughout.
- •
Ginger and Apricot
Add 1 teaspoon of ground ginger and swap the pumpkin seeds for finely chopped dried apricots. This gives a warming, slightly spiced flavour that is wonderful in cooler months.
- •
Seed and Hemp Protein
Replace the ground almonds with 40g of hemp protein powder and add a tablespoon of sunflower seeds alongside the pumpkin seeds. This bumps the protein content significantly, making each bar even more satiating.
Substitutions
- •Coconut oil → Unsalted butter or vegan butter (Use the same quantity. Butter gives a slightly richer flavour but removes the dairy free status.)
- •Medjool dates → Regular dried dates or dried figs (Soak for a little longer, around 8 to 10 minutes, as they are firmer than medjool. The flavour will be slightly less caramel-like but still delicious.)
- •Ground almonds → Sunflower seed flour or extra oats (Sunflower seed flour keeps the recipe nut free. Extra oats work too but will make the texture slightly denser.)
- •Chia seeds → Flaxseeds (ground) (Ground flaxseeds work just as well as a binder and offer a similar nutritional profile. Use the same quantity.)
- •Pumpkin seeds → Sunflower seeds or sesame seeds (Both work well and keep the nut free status. Sesame seeds add a slightly more toasted, nutty note.)
🧊 Storage
Store cooled bars in an airtight container at room temperature for up to 3 days, or in the fridge for up to 5 days. Refrigerating them also firms up the texture nicely if you prefer a denser bar. Individual bars can be wrapped and frozen for up to 2 months.
📅 Make Ahead
These flapjacks actually taste better on day two once the flavours have had time to meld together. Bake a batch at the weekend and you have a week of healthy snacks sorted. The date and banana mixture can also be prepared the night before and stored covered in the fridge, then mixed with the dry ingredients and baked the next morning.
