Recipe Overview

Servings: 4 | Total Time: 45 minutes (including cooling)

Ingredients

• 1 cup pumpkin puree
• ½ cup unsalted butter, softened
• ¾ cup granulated sugar
• 2 large eggs
• 1 teaspoon vanilla extract
• 1 tablespoon instant espresso powder
• 1¼ cups all-purpose flour
• 1 teaspoon baking powder
• ½ teaspoon ground cinnamon
• ¼ teaspoon ground nutmeg
• ¼ teaspoon salt
• ¾ cup mocha chocolate chips
• 2 tablespoons cocoa powder (for dusting)

Instructions

• Preheat your oven to 350°F and line an 8x8-inch baking pan with parchment paper, leaving slight overhang for easy removal.
• In a small bowl, whisk together the instant espresso powder with 1 tablespoon of warm water until fully dissolved; set aside.
• In a large mixing bowl, cream together softened butter and granulated sugar until light and fluffy, approximately 2 to 3 minutes of beating.
• Add eggs one at a time, beating well after each addition to fully incorporate.
• Stir in the vanilla extract and the dissolved espresso mixture, blending until the batter is smooth and evenly colored.
• Fold in the pumpkin puree gently until just combined; do not overmix.
• In a separate bowl, sift together flour, baking powder, cinnamon, nutmeg, and salt.
• Gradually fold the dry ingredients into the wet mixture until no streaks of flour remain.
• Fold in the mocha chocolate chips, reserving a small handful for the top.
• Pour the batter into the prepared pan and smooth the surface with a spatula.
• Sprinkle reserved mocha chips across the top and gently press them into the batter.
• Bake for 28 to 32 minutes, until the edges are set but the center still jiggles slightly when gently shaken. This creates the signature gooey texture.
• Remove from the oven and allow to cool in the pan for 10 minutes before transferring to a wire rack.
• Once completely cooled, cut into 4 equal squares and serve with warm Chocolate Coulis.

Chocolate Coulis

• Combine 4 ounces of dark chocolate (chopped) with ¼ cup heavy cream in a heatproof bowl.
• Heat the cream until steaming, then pour over the chocolate and let sit for 1 minute.
• Whisk until smooth and glossy, then stir in ½ teaspoon vanilla extract.
• Drizzle generously over each square just before serving.

Chip Variations

While mocha chips are the star of this recipe, you can easily customize the flavor profile with these alternatives:

• White Chocolate Chips: Bring a creamy sweetness that softens the pumpkin spice and creates a more delicate flavor balance.
• Salted Caramel Chips: Add a sophisticated sweet-and-salty contrast that complements the warm spices beautifully.
• Cinnamon Chips: Intensify the autumn spice notes and create a more cohesive, warming flavor throughout.
• Toffee Bits: Introduce a buttery crunch that adds textural interest and a subtle toasted depth.

Coulis Alternatives

Beyond the classic chocolate version, these three coulis options pair wonderfully with your pumpkin squares. Each one is written as a full step-by-step recipe so you can make any of them with confidence.

Coulis 1: Spiced Caramel Coulis

This coulis takes the familiar warmth of caramel and deepens it with a pinch of cayenne and ground cinnamon. The result is a sauce that is sweet, warming, and just slightly surprising, with a gentle heat that lingers on the palate and mirrors the autumn spices already present in the pumpkin squares. It is rich without being heavy and comes together in under 15 minutes.

Ingredients:

• 1 cup granulated sugar
• 60 ml (¼ cup) water
• 120 ml (½ cup) heavy cream, warmed
• 30 g (2 tablespoons) unsalted butter
• ¼ teaspoon ground cinnamon
• 1 small pinch of cayenne pepper
• ¼ teaspoon vanilla extract
• 1 small pinch of salt

Step 1: Make the Caramel

Combine the granulated sugar and water in a small, heavy-bottomed saucepan over medium heat. Stir gently just until the sugar dissolves, then stop stirring completely. From this point forward, do not stir the caramel. Stirring after the sugar has dissolved causes crystallization, which will make the sauce grainy. Allow the mixture to cook undisturbed, swirling the pan gently by the handle if needed to ensure even coloring. Cook for 8 to 10 minutes until the caramel turns a deep amber color, similar to the color of dark honey. Watch it carefully during the final minutes as it can go from perfect to burnt very quickly.

Step 2: Add the Cream

Once the caramel reaches a deep amber, remove the pan from the heat and immediately pour in the warmed heavy cream. Stand back as you do this, as the mixture will bubble up vigorously. Using warm cream rather than cold reduces the intensity of the reaction and helps the caramel incorporate more smoothly. Whisk the cream into the caramel until fully combined and smooth.

Step 3: Finish the Sauce

Return the pan to low heat and add the butter, ground cinnamon, cayenne pepper, vanilla extract, and salt. Stir continuously until the butter has fully melted and all of the ingredients are incorporated into a smooth, glossy sauce. Taste and adjust the cayenne if you prefer more or less heat. Remove from heat and allow to cool for 5 minutes before drizzling over the pumpkin squares. The sauce will thicken slightly as it cools.

Total Time: 15 minutes

Coulis 2: Maple Bourbon Coulis

This coulis is elegant, grown-up, and deeply satisfying. Pure maple syrup provides a natural, complex sweetness that is far more interesting than plain sugar, and a measured pour of bourbon adds warmth, vanilla undertones, and a subtle smokiness that pairs beautifully with the mocha and pumpkin flavors in the squares. The key is using real maple syrup, not pancake syrup, as the depth of flavor in genuine maple is what makes this sauce so special. The bourbon cooks down enough to mellow the alcohol while leaving behind all of its character.

Ingredients:

• 120 ml (½ cup) pure maple syrup, Grade A dark or amber recommended
• 45 ml (3 tablespoons) bourbon
• 60 ml (¼ cup) heavy cream
• 15 g (1 tablespoon) unsalted butter
• ¼ teaspoon vanilla extract
• 1 small pinch of salt

Step 1: Reduce the Maple and Bourbon

Pour the maple syrup and bourbon together into a small saucepan over medium heat. Stir once to combine, then bring to a gentle simmer. Allow the mixture to simmer for 4 to 5 minutes, stirring occasionally, until it has reduced slightly and the sharp alcohol smell has mellowed into a warm, rounded aroma. Do not boil aggressively as the maple syrup can scorch on the bottom of the pan.

Step 2: Add the Cream

Reduce the heat to low and pour in the heavy cream. Stir continuously as the cream incorporates into the maple and bourbon mixture. The sauce will lighten in color slightly and take on a smooth, flowing consistency. Cook for 2 to 3 minutes, stirring, until the sauce is uniform and beginning to thicken gently.

Step 3: Finish and Season

Remove the pan from the heat and add the butter, vanilla extract, and salt. Stir until the butter has fully melted and the sauce is glossy and smooth. Taste and adjust the salt if needed. A small pinch of salt in a sweet sauce is not about making it taste salty. It is about brightening all of the other flavors and adding balance. Allow the coulis to cool for 3 to 4 minutes before drizzling over the pumpkin squares. It can also be served at room temperature.

Total Time: 12 minutes

Coulis 3: Salted Butterscotch Coulis

Butterscotch is one of the great underappreciated dessert sauces. Made from brown sugar and butter rather than the white sugar used in caramel, butterscotch has a deeper, more complex sweetness with notes of toffee, molasses, and warm vanilla that feel tailor-made for autumn desserts. This version is finished with fleur de sel, a finishing salt that adds a delicate, mineral crunch and a savory counterpoint that makes every spoonful of this sauce more interesting than the last.

What is Fleur de Sel?

Fleur de sel, which translates from French as "flower of salt," is a hand-harvested sea salt collected from the surface of salt evaporation ponds, primarily along the Atlantic coast of France, with the most prized variety coming from the Guerande region of Brittany. It forms naturally when the conditions are just right, as thin, delicate crystals that float on the surface of the water and are skimmed off by hand before they sink and merge with the coarser salt below. Because of the labor-intensive harvesting process and the specific weather conditions required for it to form, fleur de sel is produced in limited quantities and is considered one of the finest finishing salts in the world. Its crystals are irregular, slightly moist, and dissolve slowly on the tongue, releasing a clean, bright, subtly briny flavor that is far more nuanced than ordinary table salt or even standard sea salt. In cooking, fleur de sel is never used during the cooking process where its delicate texture would be lost. It is always added at the very end, sprinkled over a finished dish just before serving, where its crystals remain intact and deliver their full flavor and textural impact. In this butterscotch coulis, a small pinch of fleur de sel added at the finish creates a beautiful contrast against the deep sweetness of the brown sugar and butter, making the sauce taste more complex, more balanced, and far more memorable than a plain butterscotch would on its own.

Ingredients:

• 100 g (½ cup, packed) dark brown sugar
• 60 g (4 tablespoons) unsalted butter, cut into pieces
• 120 ml (½ cup) heavy cream, warmed
• 1 teaspoon vanilla extract
• ¼ teaspoon fleur de sel, plus a little extra for finishing

Step 1: Melt the Butter and Sugar

Place the butter and dark brown sugar together in a small, heavy-bottomed saucepan over medium heat. Stir continuously as the butter melts and the sugar begins to dissolve into it. Unlike caramel, butterscotch is stirred throughout the cooking process, which is one of the things that makes it more forgiving and approachable. Cook the butter and sugar together, stirring constantly, for 3 to 4 minutes until the mixture is fully combined, bubbling steadily, and has deepened in color to a rich, dark amber. The mixture will smell intensely of toffee and brown sugar at this stage.

Step 2: Add the Cream

Remove the pan from the heat briefly and pour in the warmed heavy cream all at once. The mixture will bubble up as the cream hits the hot sugar and butter. Return the pan to medium-low heat and whisk continuously until the cream is fully incorporated and the sauce is smooth and uniform. Cook for 2 to 3 more minutes, whisking, until the sauce has thickened slightly and coats the back of a spoon.

Step 3: Finish with Vanilla and Fleur de Sel

Remove the pan from the heat and stir in the vanilla extract. Add the fleur de sel and stir it through the sauce. Taste the coulis carefully. The salt should be present but not dominant. It should make the butterscotch taste more like itself, sweeter, deeper, and more rounded, rather than salty. If you want a more pronounced salt contrast, add a few extra flakes directly on top of each plated square just before serving rather than adding more to the sauce itself. Allow the coulis to cool for 5 minutes before drizzling. It will thicken as it cools and can be gently rewarmed over low heat if needed.

Total Time: 12 minutes

Wine Pairings

Enhance your dessert experience with these carefully selected wine pairings:

• Tawny Port: The nutty, caramel-forward notes of a quality Tawny Port complement the mocha and pumpkin spice while the wine's natural sweetness balances the richness of the chocolate coulis.
• Moscato d'Asti: This lightly sparkling Italian wine brings bright acidity and subtle floral notes that cut through the gooey center and refresh the palate between bites.

Frequently Asked Questions

Can I use canned pumpkin puree or does it have to be fresh? Canned pumpkin puree works perfectly in this recipe and is actually the preferred choice. It has a consistent moisture content and smooth texture that fresh pumpkin can sometimes lack. Make sure you are using pure pumpkin puree and not pumpkin pie filling, which contains added sugar and spices that will throw off the balance of the recipe.

Can I make these squares ahead of time? Yes. The squares can be baked a day in advance and stored in an airtight container at room temperature. They actually improve slightly overnight as the flavors meld and the texture settles into that signature gooey consistency. The coulis can also be made ahead and stored in the refrigerator for up to 5 days. Reheat it gently over low heat or in short bursts in the microwave, stirring between each interval, until it is warm and pourable again.

How do I know when the squares are done baking? The edges should be set and pulling away slightly from the sides of the pan, but the center should still have a gentle jiggle when you shake the pan. This is intentional. The squares will continue to set as they cool, and pulling them from the oven while the center is still slightly underdone is what creates the gooey texture this recipe is known for. If the center is fully set in the oven, the squares will be too firm once cooled.

Can I substitute the espresso powder? Yes. If you do not have instant espresso powder, you can substitute 1 tablespoon of very strong brewed coffee that has been reduced slightly, or simply omit it. The espresso does not make the squares taste like coffee. It deepens and amplifies the chocolate flavor in the mocha chips and adds a subtle complexity to the batter that is worth keeping if you can.

What is the best way to cut clean squares? Allow the squares to cool completely before cutting, and use a sharp knife wiped clean between each cut. For the cleanest edges, refrigerate the baked slab for 30 minutes before slicing. A warm knife dragged through a warm bake will compress the edges and give you a ragged cut. Cold bake, sharp knife, clean wipe between cuts.

Can I freeze the squares? Yes. Wrap each square individually in plastic wrap and store in a freezer-safe container for up to 2 months. Thaw at room temperature for 1 to 2 hours before serving. The texture holds well after freezing. Do not freeze the coulis as the cream-based sauces can separate when thawed.

Which coulis is best for serving to guests who do not drink alcohol? The Spiced Caramel Coulis and the Salted Butterscotch Coulis are both completely alcohol-free and are excellent choices for all guests. The Maple Bourbon Coulis does contain bourbon, though the alcohol cooks down significantly during preparation. If you want to make a non-alcoholic version of the maple coulis, simply replace the bourbon with an equal amount of apple cider for a similar warmth and depth without the alcohol.

Can I double the recipe? Yes. This recipe scales well. Use a 9x13-inch baking pan for a double batch and add 5 to 8 minutes to the baking time, checking for the characteristic jiggle in the center before pulling from the oven. All of the coulis recipes can also be doubled without any adjustments to technique.
