Ingredients You’ll Need
This recipe calls for a handful of pantry staples and a few standout ingredients. Each one brings something essential to the Pistachio Blondie Ice Cream Sandwiches, balancing texture, richness, and flavor for a stunning frozen treat you’ll crave all summer.
- Unsalted butter (1 cup, melted): Provides classic blondie richness and a soft, tender crumb, with unsalted keeping the taste balanced.
- Light brown sugar (1½ cups, packed): Brings caramel notes and a wonderfully chewy texture to each bite.
- Large eggs (2): Help bind the batter together and lend structure and moisture to the blondies.
- Vanilla extract (2 teaspoons): Rounds out the sweetness and enhances the nutty pistachio flavor.
- All-purpose flour (2 cups): Gives the bars their sturdiness while still allowing them to stay soft and blondie-like.
- Baking powder (1 teaspoon): A touch of lift for just the right thickness.
- Salt (½ teaspoon): Balances sweetness and brings out the best in the pistachios.
- Shelled pistachios (1 cup, roughly chopped): The star of the show, delivering both crunch and gorgeous color.
- Vanilla or pistachio ice cream (1 pint, slightly softened): Rich, creamy, and ideal for spreading—homemade or store-bought both work beautifully.
How to Make Pistachio Blondie Ice Cream Sandwiches
Step 1: Prep Your Pan and Oven
Start by preheating your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, making sure you leave some overhang at the sides. This trick ensures your blondies lift right out in one piece—no sticking, no crumbs left behind! It’s the secret to neat, picture-perfect Pistachio Blondie Ice Cream Sandwiches.
Step 2: Mix the Blondie Batter
In a large mixing bowl, whisk together the melted butter and brown sugar until they’re silky smooth and glossy. Add in the eggs and vanilla extract, blending until fully incorporated. This step is the key to a rich, chewy blondie base—the foundation of your ice cream sandwiches.
Step 3: Add Dry Ingredients and Pistachios
Gently stir in the flour, baking powder, and salt, mixing until a thick batter forms. Fold in your roughly chopped pistachios, making sure every spoonful of batter is studded with those beautiful green gems. The pistachios give these blondies their flavor edge and irresistible crunch.
Step 4: Bake the Blondies
Spread the batter evenly into your prepared pan and smooth out the top. Slide the pan into the oven and bake for 22 to 25 minutes, or until the edges are golden and a toothpick inserted in the center comes out with just a few moist crumbs. Don’t overbake—moist blondies are best for holding together with ice cream!
Step 5: Cool and Layer with Ice Cream
Let the blondies cool completely right in the pan. Once cooled, lift them out using the parchment overhang. With a sharp knife, carefully slice the slab in half horizontally to create two large, flat layers. This is your blondie “bread.”
Step 6: Assemble and Freeze
Spread your softened ice cream onto one blondie half, right to the edges. Place the second blondie layer on top, pressing down just a bit to secure—but not so hard it squeezes the ice cream out. Cover and pop the whole slab into the freezer for at least 4 hours, until everything is firm and easy to slice into perfect Pistachio Blondie Ice Cream Sandwiches.
Step 7: Slice and Serve
Once totally frozen, use the parchment to lift out the slab and cut it into sandwiches—aim for 12 generous squares. For extra-clean cuts, dip your knife in warm water between slices. Serve straight from the freezer for the ultimate cool, creamy crunch.
How to Serve Pistachio Blondie Ice Cream Sandwiches

Garnishes
Turn your Pistachio Blondie Ice Cream Sandwiches into showstoppers with a shower of extra chopped pistachios, a drizzle of melted white or dark chocolate, or even a dusting of edible rose petals for a beautiful floral twist. These little extras make the sandwiches feel festive and fun, whether for all-ages parties or grown-up dinner desserts.
Side Dishes
Pair these sandwiches with fresh summer berries, a cold glass of lemonade, or a luscious berry compote on the side. The tartness of fruit is a great match for the sweetness of the blondies and ice cream, making an ideal dessert platter for picnics, showers, or lazy backyard dinners.
Creative Ways to Present
For a playful twist, wrap each Pistachio Blondie Ice Cream Sandwich in parchment and tie with colorful string for grab-and-go treats. You can also cut them into smaller squares for an elegant dessert tray, or stack them high on cake stands for a dreamy, celebratory centerpiece at your next gathering.
Make Ahead and Storage
Storing Leftovers
Store any leftover Pistachio Blondie Ice Cream Sandwiches layered between sheets of parchment in an airtight container in the freezer. This keeps them from sticking together and preserves their texture—no icy crystals or freezer burn, just chewy, dreamy bites even days later.
Freezing
These sandwiches freeze beautifully. Be sure to let the assembled slab chill until completely solid before slicing, and always wrap individual sandwiches well in plastic wrap or parchment. Stored this way, they’ll keep for up to two weeks, ready for late-night cravings or last-minute company.
Reheating
No actual reheating needed! Just let your Pistachio Blondie Ice Cream Sandwiches sit at room temperature for 2 to 3 minutes before serving. This softens the blondie ever so slightly, making for an even creamier, toothsome bite. If your ice cream is frozen rock-solid, a quick rest does wonders.
FAQs
Can I use a different type Dessert
Absolutely—pecans, walnuts, or even chopped almonds work beautifully in place of pistachios, though you’ll lose that distinctive pistachio flavor and green color. You can even try chocolate chips for an extra decadent take.
How do I keep the ice cream from squishing out when I slice the sandwiches?
The secret is to freeze the assembled slab until it’s completely firm, then use a sharp knife dipped in warm water to slice cleanly. Light pressure is all you need, and wiping the knife between cuts helps keep the edges clean.
Can I make Pistachio Blondie Ice Cream Sandwiches ahead of time?
Yes! These are the ultimate make-ahead dessert. Prepare, assemble, and freeze up to two weeks in advance. Just keep tightly wrapped until you’re ready to enjoy.
Is homemade ice cream necessary, or can I use store-bought?
Store-bought ice cream works perfectly here and saves time. Go for a premium vanilla or pistachio for the creamiest results, but homemade is also a wonderful way to play with flavors and add-ins.
How do I get neat, bakery-style sandwich squares?
Line your pan well with parchment for easy lifting and use a ruler to score and cut even portions. Dipping your knife in warm water between every cut is key for those clean, photo-ready lines.

If you’re looking to turn an ordinary day into a celebration or surprise someone with a truly wow-worthy treat, Pistachio Blondie Ice Cream Sandwiches should be at the top of your list.
