Bright, creamy, and irresistibly soft, Pistachio Pudding Sugar Cookie Bars are a dreamy dessert that brings together the richness of pistachio pudding with the simplicity of sugar cookies. With their cheerful green hue and buttery base, these bars are a crowd-pleaser for holidays, potlucks, or anytime you crave a sweet treat.

Each bite offers a velvety pistachio layer over a soft sugar cookie crust, sprinkled with a light touch of crushed pistachios or cookie crumbs. They’re easy to make, slice beautifully, and offer a nostalgic flavor that’s both unique and familiar.

These bars combine two beloved classics: the buttery sweetness of sugar cookies and the nutty charm of pistachio pudding. They’re simple to make, yet impressive to serve. Whether you need a dessert that travels well, cuts cleanly, or delivers on both flavor and texture, this recipe checks all the boxes. Plus, the fun green color makes them perfect for St. Patrick’s Day or spring gatherings.

Preparation Phase & Tools to Use

To make these Pistachio Pudding Sugar Cookie Bars, you’ll need some essential tools:

Mixing Bowls: For preparing the cookie dough and pudding topping separately.
Electric Mixer: Ensures the sugar cookie base is creamy and well-blended.
9×13-inch Baking Pan: Provides the right thickness for your cookie bars.
Offset Spatula or Spoon: For evenly spreading the pistachio layer over the cooled cookie base.
Sharp Knife or Bench Scraper: Guarantees clean, even slices for serving.

Having the right tools makes preparation smoother and helps achieve that beautiful layered finish.

Unsalted Butter: Gives the sugar cookie base its soft, rich texture.
Granulated Sugar: Adds sweetness and helps the cookie base stay tender.
Egg: Binds the ingredients and provides moisture.
Vanilla Extract: Enhances the flavor of both the cookie base and the pistachio layer.
All-Purpose Flour: Forms the structure of the cookie base.
Salt: Balances the sweetness.
Pistachio Instant Pudding Mix: The star ingredient for the creamy, nutty topping.
Milk: Activates the pudding mix into a luscious topping.
Whipped Topping (like Cool Whip): Creates a fluffy, light pistachio layer.

Cream together the unsalted butter and granulated sugar until light and fluffy. Beat in the egg and vanilla extract. Gradually add the flour and salt, mixing until just combined.

Step 2: Bake the Base

Press the dough evenly into a greased 9×13-inch baking pan. Bake at 350°F (175°C) for 18-22 minutes, or until the edges are lightly golden. Let it cool completely.

Step 3: Prepare the Pistachio Layer

In a bowl, whisk together the pistachio instant pudding mix and cold milk until it thickens. Fold in the whipped topping gently to keep it airy.

Step 4: Assemble the Bars

Spread the pistachio mixture over the cooled sugar cookie base using an offset spatula for a smooth finish.

Step 5: Chill and Serve

Refrigerate the bars for at least 1 hour to set. Slice into squares and sprinkle with crushed pistachios or cookie crumbs before serving.

Serve these bars chilled for the ultimate creamy bite. They make a beautiful addition to dessert trays or holiday platters, and their vibrant green color adds a festive touch. For a fancier finish, garnish with a sprinkle of chopped pistachios or a light dusting of powdered sugar.

To store, keep the bars in an airtight container in the refrigerator for up to 4-5 days. They also freeze well—just wrap them tightly and store for up to 2 months. Thaw overnight in the fridge before serving.

Frequently Asked Questions

Look for light golden edges and a set center. The base will firm up as it cools, so avoid overbaking.

Can I make this recipe ahead of time?

Absolutely! You can prepare the bars a day in advance and refrigerate them overnight.

Can I use homemade whipped cream instead of Cool Whip?

Yes, just make sure it’s whipped to stiff peaks to hold up the pistachio layer.

What can I use instead of pistachio pudding?

You can swap it for vanilla or white chocolate pudding, though the iconic green color and nutty flavor will change.

How should I cut the bars for clean slices?

Use a sharp knife wiped clean between cuts, or a bench scraper for even squares.
