How to Make Pistachio Pudding Sugar Cookie Bars

1. Prep the Pan

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish and line it with parchment paper, leaving an overhang on the sides for easy lifting later.

2. Mix the Dough

Cream together the softened butter, granulated sugar, and brown sugar until light and fluffy. This step helps create that irresistible chewy cookie texture. Add in the egg and vanilla extract, mixing until well combined.

Next, stir in the pistachio pudding mix—this will give your dough a beautiful green hue and deep nutty flavor. In a separate bowl, whisk together the flour, baking soda, and salt. Slowly add the dry mixture to the wet ingredients, mixing until just incorporated. Fold in chopped pistachios if using.

3. Bake

Press the dough evenly into your prepared pan. Bake for 20-25 minutes or until the edges are golden and a toothpick inserted in the center comes out clean. Let the bars cool completely in the pan before frosting.

4. Make the Frosting

In a medium bowl, beat the softened butter until creamy. Add in the pistachio pudding mix and powdered sugar. Mix on low speed, gradually adding milk (or cream) until the frosting reaches your desired consistency. Add a drop or two of green food coloring if you want a vibrant finish.

5. Frost and Garnish

Once the bars are cool, spread the frosting evenly over the top. Sprinkle with extra chopped pistachios or drizzle with melted white chocolate for added flair.

6. Slice and Serve

Use the parchment paper to lift the bars from the pan. Cut into squares or rectangles and serve!

Storage Tips

These bars are great for making ahead or saving leftovers. Store them in an airtight container:

• At room temperature for up to 3 days.

• In the refrigerator for up to 1 week (recommended if using milk in the frosting).

• To freeze, wrap individual bars in plastic wrap and store in a freezer-safe bag for up to 2 months. Thaw in the refrigerator overnight before serving.

Recipe Variations & Substitutions

• Nut-Free Version: Skip the chopped pistachios to make the recipe nut-free. You still get that pistachio flavor from the pudding mix!

• Lemon Twist: Replace the pistachio pudding with lemon pudding for a bright and citrusy version.

• Chocolate Lovers: Add mini white or dark chocolate chips to the dough or use chocolate frosting instead of pistachio.

• Festive Flair: Use holiday-themed sprinkles or food coloring to customize the bars for seasonal celebrations.

Suggested Pairings

Drinks:

• Hot matcha latte – complements the nutty notes.

• Iced coffee or cold brew – balances the sweetness.

• Prosecco or Moscato – if you’re serving these at a brunch or celebration.

Foods:

• Pair with a fruit salad for a refreshing contrast.

• Serve alongside a charcuterie board for a playful sweet-and-savory combination at parties.

FAQs About Pistachio Pudding Sugar Cookie Bars

Can I use homemade pistachio pudding instead of instant mix?

You could, but instant pudding mix is specifically formulated to work with baked goods. For best results, stick with the instant kind.

Do I have to frost them?

Nope! These bars are sweet and flavorful enough on their own. The frosting adds an extra layer of indulgence but is totally optional.

Can I double the recipe?

Yes! Just use a larger baking dish or two 9×13 pans, and be sure to adjust the baking time accordingly.

What if I don’t have a hand mixer?

No problem. You can mix everything by hand—just make sure your butter is very soft to make creaming easier.

Can I add food coloring to make them brighter?

Absolutely! A drop or two of green food coloring in the frosting will make these bars pop visually—perfect for parties or themed events.
