Pistachio Chocolate Sandwich Cookies Recipe

Soft Center. Crisp Edge. Colorful Finish.

These pistachio chocolate sandwich cookies are the kind of dessert that doesn’t whisper for attention. They call out from the plate with contrast: rich chocolate pressed against green pistachio cream, each bite soft and bold, smoothed by butter and deepened by cocoa.

You’ll learn exactly how to bake the chocolate cookies so they hold their softness. You’ll get my buttercream notes, including what makes the filling sit right between sweet and nutty. I’ll walk you through the pistachio rolling trick that makes the edges pop with both flavor and crunch.

Why These Cookies Deserve a Spot on Your Tray

They’re not drop-and-go cookies. They require a little care, yes. But what you get is a sandwich that eats like a brownie and finishes like a truffle. I serve these at holidays, small dinner parties, and yes, even on quiet Tuesday nights when I just want something that feels finished.

The cookies don’t dry out. The cream stays put. And the color contrast always makes someone ask, “What’s in this?”

Chocolate Cookie Texture Depends on the Creaming

Use softened butter, not melted. Cream it until it lightens. I give mine two to three minutes in the stand mixer on medium speed. The sugars should disappear into the butter. You’re not looking for fluff—just a smooth, soft blend. This is what keeps the baked cookies from becoming brittle.

Don’t skip the brown sugar. That hint of molasses brings a chew that granulated sugar alone can’t do. And sift your cocoa powder. Any lump you leave behind will stay stubborn.

Dry Ingredients Tip: Weigh If You Can

If you’ve ever had dry cookies when following a cocoa-based dough recipe, too much flour is often the reason. Two cups of flour means 250 grams. I use a scale, always. It saves you from wondering later why things came out stiff.

How to Get Even Chocolate Cookies for Sandwiching

Scoop, then press. I portion with a 1.5-tablespoon scoop. Then I flatten each gently—fingers or a glass base both work. Don’t skip this. It gives you the uniform height that sandwich cookies need. Uneven height means uneven pressure when you bite—and cream squeeze-out.

Watch the bake time. These cookies need just 9 to 11 minutes. The centers should look slightly underdone when you pull the tray. They’ll finish setting on the pan, then cool soft.

Pistachio Buttercream: Choose Paste Carefully

Not all pistachio pastes are made equal. Use one with no sugar added. I’ve tried sweetened versions, and they throw the balance off. The buttercream ends up cloying. A good pistachio paste smells nutty, not candy-like.

Start with room-temperature butter. Whip it until creamy before you add the paste. That first blend decides your texture.

Add sugar gradually. Powdered sugar can clump fast. I add it in three parts, scraping the bowl down as I go.

Taste before adding food coloring. The green is optional. If the buttercream looks muted but tastes right, I leave it. But if you want that clean green contrast between cookies, a drop or two of gel color does the job without thinning the texture.

Pistachio Paste: Homemade vs. Store-Bought

I’ve made my own pistachio paste a few times. It works, especially when I want full control over the texture and sweetness. But store-bought, unsweetened pistachio paste gives consistency. No shell bits. No added sugar. If you’re short on time or new to working with nuts, store-bought saves you effort and delivers a smooth, even result every time.

Assembly and Rolling: A Finishing Move That Matters

Once the cookies cool fully, fill one side with buttercream. I use a piping bag for neatness, but a spoon works. Top it with a second cookie, press gently, and make sure the filling reaches the edge.

Then comes the roll. Chopped roasted pistachios cling to the buttercream edge and add crunch in just the right measure. Don’t crush them too fine—small chunks give better texture.

Storing and Serving Tips

You can make these ahead. I chill them in a container for up to 3 days. Bring to room temp before serving, so the buttercream softens slightly.

I’ve brought these to spring picnics and winter gatherings. They don’t sweat in transport, and they hold their shape. Just layer them with parchment if you’re stacking.
