Granulated sugar (1 cup, 200g): Sweetens the batter and contributes to a chewy texture.
Pistachio paste (½ cup): The star ingredient, delivering a deep nutty flavor and natural green tint.
Large egg (1) and large egg yolks (2): These bind the ingredients and add richness.
All-purpose flour (2 cups, 255g): Provides structure while keeping the blondies tender.
Salt (¼ tsp): Enhances all the flavors perfectly.
Additional white chocolate (¾ cup, 120g): For the silky ganache topping.

How to Make Pistachio Blondies with White Chocolate and Pistachio Ganache Recipe

Step 1: Prepare Your Oven and Pan

Start by preheating your oven to 350ºF and preparing an 8×8-inch square pan. Greasing it well and lining with parchment paper is key to easy removal and clean edges—trust me, it makes life so much easier. Avoid glass pans as they tend to cook unevenly, which can affect your perfect bake.

Step 2: Melt Butter and White Chocolate Together

In a heat-proof bowl, combine the unsalted butter with the chopped white chocolate. Use gentle heat—either a microwave in short bursts, stirring frequently, or a double boiler setup—to melt them together. This step ensures a smooth, luscious base that’s essential for a fudgy texture.

Step 3: Whisk in Sugar and Pistachio Paste

Once melted, whisk in the granulated sugar to dissolve and blend the ingredients. Next, stir in the pistachio paste—it adds beautiful flavor and a lovely green hue. If you’re feeling festive, a drop of green food coloring can brighten things further, but it’s totally optional.

Step 4: Incorporate Eggs

Beat in your whole egg and egg yolks until the batter comes together smoothly. This enriches the mixture and helps the blondies stay moist and tender once baked.

Step 5: Mix in Dry Ingredients

Gently fold in the all-purpose flour and salt, mixing on low speed or by hand to avoid overworking the batter. Overmixing can lead to tougher blondies, so a light touch here keeps them soft and chewy.

Step 6: Bake Until Golden and Set

Pour the batter into your prepared pan, smoothing the top with a spatula. Bake for 35 to 40 minutes, or until the edges and top look set and a toothpick inserted comes out clean. Keep an eye—the timing can vary slightly depending on your oven, and you want that perfect gooey center.

Step 7: Cool Completely

Remove the pan from the oven and allow the blondies to cool down fully. This step is essential before applying the ganache so that it sets beautifully on top instead of melting right in.

Step 8: Make the Pistachio Ganache

In a small pan or microwave-safe bowl, combine the heavy cream and pistachio paste. Heat gently until it reaches around 175ºF or becomes very hot but not boiling. Pour this hot cream mixture through a fine strainer into the white chocolate to create a silky ganache, whisking until fully melted and smooth.

Step 9: Let Ganache Cool, Then Spread

Allow the ganache to cool and thicken at room temperature for about an hour, or pop it in the fridge, stirring every few minutes until slightly set. Once your blondies have cooled, spread this luscious ganache over the top and chill for at least 10 minutes to set.

Step 10: Slice and Serve

Once the ganache is nicely set, slice the blondies into 16 generous squares. Each piece is a delightful combination of chewy, nutty, and creamy with every bite—a true testament to this Pistachio Blondies with White Chocolate and Pistachio Ganache Recipe’s magic.

Garnishes

A sprinkle of chopped pistachios or a dusting of powdered sugar adds an elegant touch and amplifies the nutty aroma. For a pop of freshness, some finely chopped mint leaves scatter beautifully on top and complement the pistachio flavor perfectly.

Side Dishes

Pair these blondies with a scoop of vanilla bean ice cream or a dollop of whipped cream for a complete dessert experience. A cup of aromatic coffee or a floral green tea can balance the richness flawlessly and elevate your serving occasion.

Creative Ways to Present

Serve the blondies stacked with a drizzle of extra pistachio ganache or white chocolate on top. Alternatively, cut them into small bite-sized squares on a dessert platter for parties. Wrapping individual pieces in parchment with a small ribbon also makes a charming edible gift.

Make Ahead and Storage

Storing Leftovers

Keep your leftover blondies stored in an airtight container inside the fridge for up to three days. To enjoy them at their best, allow them to come to room temperature for about 20 minutes before serving so the ganache softens slightly and the flavors open up.

Freezing

You can freeze these blondies by wrapping each piece tightly in plastic wrap and placing them in a freezer-safe container for up to 2 months. When ready, thaw them in the fridge overnight, then bring to room temperature before serving to maintain that creamy, fudgy texture.

Reheating

Reheat a single piece in the microwave for about 10 seconds to warm it and make the ganache ooze delightfully without melting completely. Avoid overheating as it can affect the gooey consistency and delicate flavors.

FAQs

Can I make the pistachio paste from scratch?

Absolutely! If you have raw or roasted pistachios on hand, you can blend them with a little neutral oil until smooth, adding a pinch of salt to enhance the flavor. Homemade pistachio paste tends to be fresher and packed with more natural oils, which can make your blondies even more flavorful.

Is it possible to substitute white chocolate with milk or dark chocolate?

While you can try, white chocolate pairs best here to maintain the blondies’ delicate sweetness and creamy flavor. Milk or dark chocolate will change the taste and texture considerably, making them less traditional and potentially overpowering the pistachio notes.

Can I use almond paste instead of pistachio paste?

Although almond paste has a lovely nutty flavor, it’s not a direct substitute in this recipe. The pistachio paste brings a unique sweetness and color that is central to the character of these blondies. Using almond paste will create a different taste experience but could be interesting if you want to experiment.

How important is it to use an 8×8 inch pan?

An 8×8 inch pan ensures the blondies have the perfect thickness for a chewy yet fully baked center. A larger pan will produce thinner blondies that bake faster and might dry out, while a smaller pan could lead to underbaked batter unless you adjust the cooking time accordingly.

Can I make these gluten-free?

Yes! Substitute the all-purpose flour with a gluten-free baking blend of equal weight that is suitable for cakes or cookies. Be mindful that the texture may vary slightly but the flavor combination of pistachio and white chocolate will remain deliciously intact.
