Ingredients You’ll Need

Each ingredient here is simple yet carefully chosen to enrich the texture, depth, and flavor of the dish. Together, they create a balance that feels both familiar and indulgent.

All-purpose flour: Provides structure for both the shortbread and brownie layers, ensuring the right crumb and chewiness.
Granulated sugar: Sweetness is key, and it helps create a tender crumb and glossy finish in the ganache.

Fine sea salt: Enhances the chocolate flavor and balances the sweetness throughout the dessert.
Avocado oil: A subtle, neutral oil that keeps the shortbread moist and adds richness without overpowering the nuts or chocolate.
Chopped hazelnuts or pecans: Brings a toasty, crunchy texture and nutty aroma that complements the chocolate beautifully.

Vanilla extract: Adds warmth and depth that ties all the flavors together.
Large eggs: Bind ingredients and give the brownie its fudgy, dense texture.
Dutch process cocoa: Provides a smooth, rich chocolate flavor with a deep color.

Dark chocolate (chopped fine): Essential for the ganache, giving it that glossy shine and rich taste.
Heavy cream: Creates the silky texture in the ganache when combined with the chocolate.
Chocolate hazelnut spread: Boosts the nutty chocolate flavor, making the ganache extra decadent and smooth.

Directions

Step 1: Line an 8×8 inch square baking pan with parchment paper, making sure to leave some overhang on all sides for easy removal. Preheat your oven to 350 degrees Fahrenheit to get it ready for baking.

Step 2: To prepare the shortbread layer, whisk together 1 ½ cups of flour, ⅓ cup sugar, and 1 teaspoon of sea salt in a bowl until well combined. Gently fold in ½ cup avocado oil and the chopped hazelnuts with a rubber spatula. If the dough feels too wet, sprinkle up to 2 extra tablespoons of flour and fold in just until it firms up. Press this mixture evenly into the lined baking pan and bake it for about 12 minutes, until it’s set but not browned too much.

Step 3: While the shortbread bakes, mix up the brownie batter. In a separate bowl, whisk together ½ cup avocado oil, 1 cup sugar, ½ teaspoon salt, and 1 teaspoon vanilla extract. Add one egg and beat vigorously for at least 30 seconds, then repeat with the second egg. Stir in ½ cup Dutch process cocoa and ¼ cup flour just until smooth and combined; avoid overmixing to keep the brownies tender.

Step 4: Once the shortbread comes out of the oven, immediately pour the brownie batter over it, spreading it evenly. Return the pan to the oven and bake for another 25 to 30 minutes. You’ll know it’s done when a toothpick inserted near the center comes out with a few moist crumbs but no raw batter.

Step 5: Allow the brownies to cool completely in the pan, which usually takes about an hour at room temperature. While they cool, prepare the ganache by placing the finely chopped dark chocolate in a heatproof bowl. Warm the heavy cream gently on the stove until it just starts to steam and bubble around the edges—careful not to boil. Pour the hot cream over the chocolate and stir until glossy and smooth. Then, mix in 2 tablespoons of chocolate hazelnut spread until fully incorporated.

Step 6: Pour the ganache evenly over the cooled brownies and smooth out with a spatula. Cover the pan and chill in the refrigerator for at least an hour to let the ganache firm up before slicing into squares and serving.

Servings and Timing

This Chocolate Hazelnut Shortbread Brownie with Ganache Recipe yields about 16 generous servings—ideal for parties or sharing with loved ones. You’ll spend roughly 15 minutes prepping, 40 minutes baking in two stages, plus about an hour cooling and chilling before serving. Altogether, you’re looking at around 1 hour and 55 minutes from start to finish. The waiting is worth it for such a beautifully layered dessert.

How to Serve This Chocolate Hazelnut Shortbread Brownie with Ganache Recipe

The image shows several square brownies arranged closely on a white marbled surface. Each brownie has two layers: a thick, light cream-colored base filled with bits of walnuts, and a darker, rich chocolate top layer with a cracked, slightly shiny crust. Some brownies are stacked to show the inside layers clearly. The brownies have rough edges and a dense texture. Photo taken with an iphone --ar 4:5 --v 7

When I serve this treat, I love to keep it simple so the flavors can shine. I usually plate the brownies at room temperature, slicing them into squares that show off the lovely layers. A light dusting of powdered sugar or a sprinkle of extra chopped hazelnuts on top of the ganache adds a charming finishing touch without overpowering the rich chocolate notes.

For pairings, I find these brownies go incredibly well with a cup of freshly brewed espresso or a creamy cappuccino, especially when enjoying as an afternoon indulgence. If it’s an evening gathering, a glass of ruby port or a nutty amaretto cocktail really complements the hazelnut undertones beautifully. For non-alcoholic options, a cold glass of milk or a robust chai latte brings out the warm spices in the cocoa.

This recipe shines at celebrations like birthdays, holiday parties, or even casual weekend dessert tables. Serving chilled works great for hot summer days, while room temperature or slightly warmed (briefly in the microwave for 10 seconds) suits cozy winter evenings. I usually keep portions modest since they’re quite rich, making each piece feel like a little gift.

Variations

I love experimenting with this Chocolate Hazelnut Shortbread Brownie with Ganache Recipe to suit different tastes and dietary needs. For instance, swapping the hazelnuts for toasted pecans or even macadamia nuts gives a lovely twist on the nutty flavor. If you prefer a milder chocolate, using milk chocolate for the ganache creates a sweeter finish that’s equally delicious.

If gluten is a concern, I’ve had good success substituting the all-purpose flour with a gluten-free blend that includes xanthan gum for structure. The texture remains buttery and tender once baked. For a vegan adaptation, replacing eggs with flax eggs and choosing coconut oil instead of avocado oil works well, though I recommend adding a little extra flour to maintain the shortbread’s firmness.

You can also try switching up the cooking method by baking the shortbread crust and the brownie layer in separate pans if you want to control baking times more precisely or create individual bars. Some days I even add a sprinkle of flaky sea salt on the ganache before chilling to bring out all the chocolate’s richness with every bite.

Storage and Reheating

Storing Leftovers

I store leftover brownies in an airtight container at room temperature if I plan to eat them within 2 days. For longer storage, they keep well in the refrigerator for up to a week, which helps the ganache stay firm. To keep the layers intact, I layer parchment or wax paper between pieces when stacking in the container.

Freezing

You can definitely freeze these brownies! I usually cut them into individual squares first, then wrap each piece tightly in plastic wrap and place them in a freezer-safe container or bag. They’ll keep fresh in the freezer for up to 3 months. To thaw, I move them to the refrigerator overnight and let them come to room temperature before serving for the best texture.

Reheating

Since these brownies are rich and layered with ganache, I avoid direct reheating methods that can melt the topping unevenly. Instead, I let them come to room temperature naturally or give them a quick 5 to 10-second zap in the microwave to take the chill off without melting the ganache too much. If you prefer warm brownies, heating them briefly before adding fresh ganache or a scoop of vanilla ice cream is a delightful option.

FAQs

Can I use regular butter instead of avocado oil in this recipe?

Absolutely! While avocado oil offers a neutral flavor and moist texture, melted butter can add a nice richness and buttery taste. Just make sure to use the same amount of melted butter as the oil called for, and adjust baking times slightly if needed.

What if I don’t have Dutch process cocoa; can I use natural cocoa powder?

You can substitute natural cocoa powder, but keep in mind that Dutch process cocoa is milder and less acidic, which affects the flavor and how the batter rises. If using natural cocoa, you might notice a slightly more bitter taste and a difference in texture, but it will still be delicious.

Can I make this recipe nut-free?

Yes! Simply omit the chopped hazelnuts or pecans from the shortbread layer. To keep some texture, you might add seeds like pumpkin or sunflower seeds, or even small chocolate chips for extra interest. Just be sure to avoid cross-contamination if allergies are a concern.

How do I know when the brownie layer is done baking?

Look for slightly firm edges and a center that still looks a bit soft but no liquid batter visible. A toothpick inserted near the center should come out with moist crumbs but not wet batter. The brownie will continue to set as it cools, so avoid overbaking to keep it fudgy.

Is it necessary to chill the ganache before serving?

Chilling the ganache helps it set into a smooth, firm layer that’s easier to slice and looks polished. If you’re in a hurry, you can serve it slightly chilled or at room temperature, but it may be softer and less neat on the plate. For the best presentation and texture, I highly recommend giving it that hour in the fridge.
