Healthy Pumpkin Pie Spice Dessert Bars with Low Sugar Almond Crust
Bar format solves the pie problem. Pumpkin pie is beloved but awkward: it requires a round tin, blind baking, a wet filling that needs precise temperature management, and a crust that has a habit of going soggy at the base. Pumpkin pie spice dessert bars keep all the flavour of the original in a format that is easier to make, easier to transport, easier to store and easier to cut into neat, even portions. Baked in a square tin, sliced into squares, they stack in containers and keep in the fridge for four days without any loss of quality. The almond flour crust is pressed, not rolled, and the spiced filling sets to a smooth, sliceable layer that is genuinely lower in sugar than anything from a supermarket bakery.
Why this recipe works
The bar format allows a thinner layer of filling relative to crust, which means less baking time and less risk of the filling cracking or over-baking. Almond flour crust pressed into a lined square tin and pre-baked creates a firm, crumbly base that does not require blind baking weights or complicated technique. Pumpkin puree, coconut milk and eggs create the filling with a small amount of maple syrup as the primary sweetener. The spice blend, cinnamon, ginger, cloves and a small amount of nutmeg, provides the characteristic warmth that makes pumpkin desserts so recognisable and satisfying in autumn.
Getting it right
Pre-bake the almond crust until lightly golden before adding the filling. An under-baked crust under a wet filling will remain soft and lack the texture contrast that makes the bars satisfying.
Pour the filling slowly and evenly over the pre-baked crust. Any air bubbles on the surface of the filling will remain visible after baking; tap the tin gently on the counter after pouring to bring them to the surface where they can be popped.
Common mistakes
Baking the filling at too high a temperature causes the edges to set and crack before the centre is cooked through. Use a low, consistent oven temperature of around 160 degrees Celsius.
Slicing before the bars are completely cold and refrigerated produces a filling that smears rather than slices. Refrigerate for at least three hours before cutting.
Substitutions
Butternut squash puree replaces pumpkin with a sweeter, slightly lighter result. Sweet potato puree produces a denser, more vibrant orange filling. Coconut cream can replace the coconut milk for a richer, more indulgent filling layer.
Serving suggestion
Serve chilled in clean, even squares. A small dollop of coconut whipped cream on each bar and a light dusting of cinnamon provides a clean, attractive finish. These are excellent on a Thanksgiving dessert table cut into small bites.
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.
