Ingredients

  • Unsalted butter: select a high quality European style when possible for the richest flavor
  • Large eggs: provide structure and keep the bars tender make sure they are at room temperature for best mixing
  • Pistachio instant pudding mix: creates that signature nuttiness and gorgeous tint opt for a well known brand for depth and color
  • Sugar cookie mix: gives you the right sweetness and chewy bite choose a mix that uses real vanilla if possible

Step-by-Step Instructions

Cream the Butter and Eggs:
In a large mixing bowl use a sturdy spatula or hand mixer to whip the softened butter eggs and pistachio pudding mix until the mixture looks smooth creamy and lightly fluffed this step is key for a tender bar
Mix in the Cookie Mix:
Add the sugar cookie mix slowly blending it thoroughly with the wet mixture until you have a sticky soft dough do not rush this as you want everything fully combined without dry pockets
Prepare the Pan:
Grease a 10 x 15 inch baking sheet well making sure to get the corners then dollop all the dough and press it evenly all the way to the edges with clean hands or a spatula smooth the top for even baking
Bake and Cool:

I adore how the green color pops on a dessert table especially in spring and my kids always ask if it is magic because it disappears so fast when friends come over

Frequently Asked Questions

→ What gives these bars their green color?

The vibrant green hue comes from pistachio instant pudding mix combined with the other ingredients, resulting in a natural-looking shade.

→ Can I substitute other pudding flavors?

For a flavor change, you can swap the pistachio pudding mix with other instant pudding flavors, but this will alter both the color and taste.

→ Do I need to use unsalted butter?

Unsalted butter is recommended to control the saltiness, but you may use salted butter if that's all you have—just expect a slightly saltier result.

→ How do I know when the bars are baked through?

The edges should be lightly golden, and the center should set without excessive browning. Overbaking will dry out the bars, so keep a close watch near the end.

→ Can I add chopped pistachios to the dough?

Yes, you can fold in chopped pistachios for extra crunch and flavor, or sprinkle them on top before baking for added texture.
