A Little Autumn Indulgence
There is something wonderfully comforting about the flavours of autumn. The warm aroma of pumpkin, the richness of caramel, and the delicate sweetness of vanilla come together in this delightful dessert that feels both rustic and elegant.
These Salted Caramel Pumpkin Gâteau Squares are made with three delicious layers. A buttery, lightly salted shortbread crust creates the perfect foundation for a smooth pumpkin filling enriched with homemade caramel. The finishing touch is a generous layer of mascarpone whipped cream, adding a light and velvety contrast to the richness of the filling.
The secret to this recipe is allowing the sugar to caramelize to a deep amber colour. This gives the pumpkin filling a beautiful depth of flavour, balancing the natural sweetness of the pumpkin with a delicate hint of bitterness from the caramel.
Perfect for Thanksgiving gatherings, autumn celebrations, afternoon coffee, or simply when you crave something homemade and special, these little squares are a lovely addition to any dessert table.
Zosia's Tips for the Perfect Gâteau
Choose the right pumpkin: Use pure pumpkin purée rather than pumpkin pie filling, which already contains added sugar and spices.
Don't rush the caramel: A deep amber colour creates the beautiful bittersweet caramel flavour that makes this dessert special. Avoid taking it too dark, as burnt caramel will taste bitter.
Use room-temperature ingredients: Room-temperature cream, butter, and eggs help the filling blend smoothly.
Watch the filling carefully: The centre should have a gentle wobble when removed from the oven. It will firm up as it cools.
Cool completely before topping: The mascarpone cream must be added only when the pumpkin layer is completely cool.

Preparation time: 25 minutes
Baking time: 45 minutes
Cooling time: Approximately 2–3 hours
Total time: Approximately 3 hours 10 minutes
Servings: 16 squares
Pan size: 21 x 21 cm (8 x 8 inches)
Oven temperature: 350°F (175°C) for the crust and 325°F (160°C) for the filling
Ingredients:
For the buttery shortbread crust
190 g all-purpose flour
50 g powdered sugar
½ teaspoon sea salt
145 g unsalted butter, cold and cut into small pieces
For the salted caramel pumpkin filling
100 g fine granulated sugar
2 tablespoons water
1 cup (240 ml) heavy cream (35%), at room temperature
1 cup pure pumpkin purée (not pumpkin pie filling)
30 g unsalted butter, at room temperature
¼ cup brown sugar
A pinch of sea salt
2 teaspoons vanilla extract
2 large eggs, lightly beaten and at room temperature
For the mascarpone whipped cream topping
⅓ cup mascarpone cheese, cold
⅔ cup heavy cream (35%), cold
Instructions:
Step #1 Prepare the shortbread crust
Preheat the oven to 350°F (175°C).
Lightly butter the bottom and sides of a 21 x 21 cm square baking pan. Line the pan with parchment paper, leaving a little overhang on the sides to make removing the finished gâteau easier.
On a clean work surface, combine the flour, powdered sugar, and sea salt. Add the cold butter pieces and work them into the dry ingredients using your fingertips until the mixture resembles coarse crumbs and begins to come together into a dough.
Transfer the dough into the prepared baking pan. Press it evenly over the bottom, making sure it reaches all the corners.
Bake for approximately 20 minutes, or until the crust is lightly golden and fragrant.
Step #2. Make the salted caramel pumpkin filling
Place the granulated sugar in the centre of a medium-sized, heavy-bottomed saucepan. Carefully pour the water around the sugar.
Heat over medium heat without stirring. Allow the sugar to dissolve and gradually caramelize. You can gently swirl the saucepan occasionally to encourage even caramelization.
Watch closely as the sugar changes colour. Allow it to reach a deep amber caramel shade, as this is what gives the filling its wonderful, rich caramel flavour.
Remove the saucepan from the heat. Slowly pour in the room-temperature heavy cream, a little at a time, stirring carefully with a wooden spoon. Be cautious, as the caramel will bubble vigorously and release very hot steam.
Once the cream has been incorporated, add the butter, pumpkin purée, brown sugar, sea salt, and vanilla extract.
Whisk everything together until the mixture is smooth, creamy, and evenly combined.
Allow the caramel pumpkin mixture to cool slightly for about 5 minutes before adding the eggs. This is important to prevent the eggs from scrambling.
Gradually whisk in the beaten eggs until fully incorporated. Keep the filling gently warm while the crust finishes baking, but do not allow it to boil.
Step #3. Bake the pumpkin gâteau
Once the shortbread crust is beautifully golden, remove it from the oven.
Reduce the oven temperature to 325°F (160°C).
Pour the prepared salted caramel pumpkin filling evenly over the warm crust.
Return the pan to the oven and bake for approximately 25 minutes, or until the edges are set and the centre still has a very slight wobble.
Avoid overbaking, as the filling will continue to set as it cools.
Remove from the oven and allow the gâteau to cool completely at room temperature.
A little patience makes all the difference! Allow the cake to cool thoroughly before adding the mascarpone topping. I prefer to let it cool at room temperature rather than placing it in the refrigerator immediately, as this helps preserve the delicate texture of the buttery crust.
Step #4. Prepare the mascarpone whipped cream
Once the pumpkin gâteau has cooled completely, prepare the topping.
Place the cold mascarpone cheese and cold heavy cream into a mixing bowl.
Using an electric mixer, whip on medium speed until the mixture becomes smooth, thick, and holds soft-to-medium peaks.
Be careful not to overwhip, as mascarpone cream can become grainy if beaten for too long.
Step #5. Assemble and serve
Carefully lift the completely cooled gâteau out of the pan using the parchment paper overhang.
Spread the mascarpone whipped cream evenly over the pumpkin layer, creating a smooth and delicate finish.
Using a sharp knife, gently cut the cake into 16 small squares. Be sure to precut the cake before refrigerating so the shortbread base softens enough to allow clean, easy slices.
Serve immediately, or refrigerate in an airtight cake container or covered cake dome until ready to enjoy.
Store the finished gâteau squares in an airtight container in the refrigerator for up to 5 days.
