Healthy Pumpkin Pie Spice Dessert Bars with Low Sugar Almond Crust

If you have ever craved that warm, cosy flavour of pumpkin pie but wanted something you could actually feel good eating, these bars are about to become your new favourite thing to make. Built on a naturally sweet almond and oat base and filled with a silky spiced pumpkin custard, they deliver every bit of that classic autumn comfort without the sugar overload that comes with traditional pie. They are brilliant for meal prepping ahead of a gathering, slicing into lunchboxes throughout the week, or simply keeping in the fridge for those moments when you want something genuinely satisfying but do not want to undo a day of good eating. Nutritionists often talk about finding healthy swaps that do not feel like a compromise, and honestly, this is one of those rare recipes where the lighter version actually tastes better than the original.
The base is made from ground almonds, rolled oats and a small amount of coconut oil, sweetened with just a touch of pure maple syrup. Ground almonds bring healthy monounsaturated fats and a gentle nuttiness, while the oats add soluble fibre that helps you feel fuller for longer. The filling leans heavily on pure pumpkin puree, which is naturally packed with beta-carotene, potassium and vitamin C. Instead of loading it with refined white sugar, a modest amount of coconut sugar does the job beautifully. Coconut sugar has a lower glycaemic index than regular sugar, meaning it causes a slower, gentler rise in blood sugar. The spice blend is where the magic really happens: a generous combination of cinnamon, ginger, nutmeg and a hint of clove gives the filling incredible depth and warmth. Cinnamon in particular has been studied for its potential role in supporting blood sugar regulation, so leaning into the spices rather than relying on sweetness is a genuinely smart move here.
Texture-wise, these bars sit beautifully in that space between a firm custard tart and a soft, yielding brownie. The almond oat base holds its shape well when chilled, giving you a satisfying bite that contrasts with the smooth, creamy pumpkin layer on top. They are lovely served cold straight from the fridge, but if you prefer a warmer dessert experience, a very brief 20-second blast in the microwave brings the spice aromas right back to life. A small dollop of plain Greek yoghurt or a light coconut cream on top makes them feel indulgent without adding much sugar at all. They are equally at home on a Thanksgiving dessert table as they are on a Tuesday afternoon when you fancy something cosy and wholesome.
From a dietary standpoint, these bars are naturally gluten-free as long as you use certified gluten-free oats, which makes them a genuinely inclusive option for guests with intolerances. They are dairy-free, refined sugar-free and contain no artificial sweeteners whatsoever. Each bar clocks in at around 165 calories with nearly 4 grams of fibre and only 7 grams of sugar, making them a dramatically lighter choice compared to a traditional pumpkin pie slice, which can easily hit 320 calories and 25 grams of sugar per serving. The protein from the eggs and almonds helps make each bar genuinely sustaining rather than just a quick sugar hit. For anyone managing their blood sugar, watching their calorie intake or simply trying to eat a little more mindfully during the festive season, these healthy pumpkin pie spice dessert bars with low sugar content are a genuinely brilliant solution that does not ask you to sacrifice a single bit of joy.
Ingredients
- 150 g ground almonds (also called almond flour)
- 80 g rolled oats (use certified gluten-free if needed)
- 3 tbsp pure maple syrup (divided, 1 tbsp for base and 2 tbsp for filling)
- 3 tbsp coconut oil (melted and cooled)
- 1 tsp vanilla extract
- 1 pinch fine sea salt (for the base)
- 400 g pure pumpkin puree (canned or homemade, not pumpkin pie filling)
- 2 large eggs (at room temperature)
- 120 ml full-fat coconut milk (from a can, shaken well)
- 3 tbsp coconut sugar (or light brown sugar as an alternative)
- 2 tsp ground cinnamon
- 1 tsp ground ginger
- 0.5 tsp ground nutmeg (freshly grated is even better)
- 0.3 tsp ground clove
- 1 tbsp arrowroot powder (or cornstarch, helps the filling set cleanly)
Instructions
- 1
Preheat your oven to 175 degrees Celsius (350 degrees Fahrenheit). Line a 20cm by 20cm square baking tin with baking paper, leaving some overhang on two sides so you can lift the bars out easily later.
Greasing the sides of the tin lightly before laying the paper helps it stay flat against the edges.
- 2
In a medium bowl, combine the ground almonds, rolled oats and pinch of sea salt. Pour in the melted coconut oil, 1 tablespoon of maple syrup and the vanilla extract. Mix well until the mixture resembles damp, clumping sand.
The base should just hold together when you press a small amount between your fingers. If it feels too crumbly, add half a teaspoon more coconut oil.
- 3
Tip the base mixture into the prepared tin. Press it down firmly and evenly using the back of a spoon or the flat bottom of a glass. Make sure you get right into the corners for an even bake.
- 4
Bake the base for 10 minutes until it smells lightly toasty and the edges are just starting to turn golden. Remove from the oven and set aside to cool slightly while you make the filling.
Do not over-bake the base at this stage as it will go back into the oven with the filling on top.
- 5
In a large bowl, whisk together the pumpkin puree, eggs, coconut milk, remaining 2 tablespoons of maple syrup and coconut sugar until very smooth. Add the cinnamon, ginger, nutmeg, clove and arrowroot powder, then whisk again until everything is fully combined and the batter looks silky and uniform.
Taste the filling at this point and adjust spicing to your preference. Some people love an extra pinch of cinnamon.
- 6
Pour the pumpkin filling evenly over the pre-baked base. Use a spatula to gently spread it into the corners if needed.
- 7
Return the tin to the oven and bake for a further 25 minutes. The filling should look set around the edges but may have a very slight wobble in the very centre. It will firm up as it cools.
If the edges of the base are browning too quickly, tent a small piece of foil loosely over the tin for the last 10 minutes.
- 8
Remove the tin from the oven and allow the bars to cool completely at room temperature for at least 30 minutes. Then transfer to the refrigerator for a minimum of 1 hour, or ideally overnight, before slicing.
Chilling is the key step that makes the bars slice cleanly. Rushing this will result in messy edges.
- 9
Once thoroughly chilled, lift the bars out of the tin using the baking paper overhang. Place on a chopping board and slice into 12 even bars using a sharp knife. Wipe the blade between cuts for the neatest results.

Pro Tips
- ✓
Use a baking tin with straight sides rather than sloped ones for the neatest bar shapes.
- ✓
Always shake your can of coconut milk vigorously before opening to recombine the cream and liquid layers.
- ✓
Make sure your eggs are at room temperature before whisking into the filling. Cold eggs can cause the mixture to split slightly.
- ✓
Do not swap pumpkin puree for pumpkin pie filling. The latter already contains sugar and spices and will make the bars far too sweet.
- ✓
A sprinkle of extra cinnamon dusted over the top just before serving looks beautiful and adds a little aromatic burst.
- ✓
For super clean slices, run your knife under hot water, wipe dry and then cut.
Frequently Asked Questions
Variations
- •
Chocolate Swirl Pumpkin Spice Bars
Before baking, dollop 3 tablespoons of a mix of melted dark chocolate (85 percent cocoa) and 1 teaspoon of coconut oil over the pumpkin filling. Use a skewer to swirl it through the surface for a striking visual and a rich, slightly bitter contrast to the sweet spiced pumpkin.
- •
Pecan Crunch Topping
Scatter a small handful of roughly chopped raw pecans over the top of the filling before baking. They toast beautifully in the oven and add a satisfying crunch alongside the creamy filling.
- •
Ginger Snap Base
Add an extra half teaspoon of ground ginger and a quarter teaspoon of black pepper to the base mixture for a more pronounced ginger snap flavour that pairs brilliantly with the warm spiced filling.
- •
Vegan Version
Replace the 2 eggs with 2 flax eggs and use coconut cream in place of coconut milk for a richer, fully plant-based bar. Allow extra chilling time as the filling will take a little longer to fully set.
Substitutions
- •Ground almonds → Sunflower seed flour (A great nut-free option that works in a near-identical ratio and gives a similar tender, slightly nutty base.)
- •Coconut sugar → Light brown sugar (Use the same quantity. The flavour will be slightly less caramel-like but still delicious.)
- •Coconut oil → Unsalted butter (Use melted and cooled butter in the same quantity if you are not following a dairy-free diet.)
- •Arrowroot powder → Cornstarch (Use the same amount. Both work equally well for helping the filling set cleanly.)
- •Full-fat coconut milk → Unsweetened oat milk (The filling will be slightly less rich and creamy but will still set well. Avoid low-fat versions as they can make the filling watery.)
- •Maple syrup → Raw honey (Use the same quantity. Note that the bars will no longer be vegan if you use honey.)
🧊 Storage
Store the bars in an airtight container in the refrigerator for up to 5 days. Keep them in a single layer or separate layers with baking paper between them to prevent sticking. They taste best cold or at room temperature.
📅 Make Ahead
These bars are ideal for making a day ahead. Prepare and bake them the evening before, then leave overnight in the refrigerator. The flavours deepen beautifully as they rest and the texture sets up perfectly for clean slicing. Simply slice and serve straight from the fridge.
