These Pistachio Cheesecake Bars are a rich, creamy dessert that blends the classic smoothness of cheesecake with vibrant pistachio flavor. A buttery graham cracker crust holds a silky pistachio cheesecake layer, and a glossy pistachio white chocolate ganache tops it off. They’re perfect for parties, holidays, or anytime you want a special homemade treat.
Ingredients
For the Graham Cracker Crust
- 4 cups graham cracker crumbs
- 1/3 cup granulated sugar
- 3/4 cup melted butter
- 1/4 teaspoon salt
For the Pistachio Cheesecake Filling
- 24 ounces cream cheese, softened
- 1 cup granulated sugar
- 3 eggs
- 3/4 cup sour cream
- 1 tablespoon vanilla extract
- 1/2 teaspoon salt
- 1 cup pistachio paste (homemade or store-bought)
- 1/4 cup pistachio ganache or cream (optional swirl)
For the Pistachio White Chocolate Ganache Topping
- 2 cups white chocolate chips
- 1/2 cup pistachio paste
- 1/2 cup heavy cream
Optional Garnishes
- 1/2 cup chopped pistachios
- 2 tablespoons edible rose petals (for decoration)
Step-by-Step Instructions
1. Prepare the Crust
- Preheat your oven to 325°F (around 163°C).
- Line a 9×13-inch baking pan with parchment paper.
- In a bowl, combine the graham cracker crumbs, melted butter, sugar, and salt until evenly mixed.
- Press the mixture firmly and evenly into the bottom of the prepared pan so the crust holds together well.
- Bake the crust for about 10 minutes to set it. Then remove from the oven and let it cool slightly.
2. Make the Pistachio Paste (If You’re Making It Homemade)
- Preparing homemade pistachio paste involves blanching raw pistachios to remove their skins, then blending them with sugar and a little oil until smooth. This gives a natural green color and deep nutty flavor to the cheesecake.
3. Prepare the Cheesecake Filling
- In a large bowl or stand mixer, beat the softened cream cheese until completely smooth.
- Add the sugar and mix until fully combined.
- Add the eggs one at a time, mixing on low speed so you don’t whip too much air in.
- Mix in the sour cream, vanilla extract, and salt until smooth.
- Gently fold in the pistachio paste with a spatula until evenly incorporated. The filling should be pale green and silky.
4. Bake the Cheesecake
- Pour the pistachio cheesecake filling over the prepared crust and spread into an even layer.
- Tap the pan gently on the counter to release air bubbles.
- Bake at 325°F for 40–45 minutes, or until the edges are set but the center still has a slight jiggle.
- Remove from the oven and let it cool to room temperature.
- Chill in the refrigerator for at least 4 hours or overnight so the cheesecake sets fully.
5. Make the Pistachio Ganache
- Warm the heavy cream in a small saucepan until steaming (do not boil).
- Add a small portion of the white chocolate chips and stir until they begin to melt.
- Continue adding the white chocolate chips gradually, stirring until completely melted and smooth.
- Whisk in the pistachio paste until the ganache is glossy and evenly combined.
- Let it cool slightly before pouring it over the chilled cheesecake layer.
- Spread the ganache into a thick, even layer on top.
6. Garnish and Serve
- For a decorative finish, sprinkle chopped pistachios over the top.
- Add edible rose petals if desired for extra color and flair.
- Use a hot knife (wipe clean between slices) to cut clean bars before serving.

Tips for Best Results
- Make sure all dairy ingredients are at room temperature before mixing to get a smooth, lump-free cheesecake.
- If your ganache seems too thick, warm it gently with a splash of cream; if too thin, let it cool a bit before spreading.
- These bars taste even better the next day as the flavors deepen.
Storage
- Store leftover bars covered in the refrigerator for up to 5 days.
- You can freeze individual bars wrapped in parchment and plastic wrap, then thaw overnight in the fridge before serving.
