When you’re craving something crispy, buttery, and just a little fancy, these Keto Pistachio Shortbread Cookies hit the sweet spot. You don’t need fancy tools or hard-to-find ingredients to make these; just a bowl, some common pantry items, and your love for pistachios. Perfect for keto beginners or seasoned low-carb bakers, this recipe will have your friends and family asking, “Are these really keto?” Yes, they are—no guilt included.

Why Pistachios?

Pistachios bring something special to these cookies. They’re buttery, slightly sweet, and have that irresistible crunch. Plus, they’re packed with healthy fats, which makes them perfect for the keto lifestyle. If you’re not already sold, pistachios also add a beautiful green hue to your cookies. These treats not only taste great but also look stunning on a plate.

Ingredients You’ll Need

Here’s the full list, and trust me—it’s not complicated.

• 1 ¾ cups almond flour (finely ground works best)
• ½ cup powdered erythritol (or your favorite keto-friendly sweetener)
• ½ cup butter, softened (grass-fed if possible for extra flavor)
• 1 teaspoon vanilla extract
• ¼ teaspoon almond extract (optional but adds depth)
• ¼ teaspoon salt
• ½ cup chopped pistachios (unsalted for better control over saltiness)
• 1 tablespoon unsweetened almond milk (optional, to adjust the dough)

Step-by-Step Instructions

1. Prep Your Ingredients

First, take your butter out of the fridge and let it soften. This is key to getting that smooth, melt-in-your-mouth texture. While you’re waiting, chop your pistachios into small pieces. You don’t want huge chunks; a little goes a long way in each cookie. Preheat your oven to 325°F (163°C) and line a baking sheet with parchment paper.

2. Mix the Dough

In a large mixing bowl, combine the almond flour, powdered erythritol, and salt. Give it a quick stir so everything’s evenly distributed. Add the softened butter, vanilla extract, and almond extract (if using). Use a spatula or clean hands to mix everything into a dough. It might feel a bit crumbly at first, but keep at it—it’ll come together. If it feels too dry, add the almond milk, a little at a time, until the dough holds its shape.

3. Add the Pistachios

Fold in the chopped pistachios gently, making sure they’re evenly spread throughout the dough. This is what takes the cookies to the next level with bursts of nutty flavor in every bite.

Shaping the Cookies

4. Roll and Slice

For that classic shortbread look, roll the dough into a log about 2 inches in diameter. Wrap it in plastic wrap and pop it into the freezer for 20 minutes. This step is essential to firm up the dough, making it easier to slice.

Once the dough is chilled, take it out and slice it into ¼-inch thick rounds. Aim for even slices so everything bakes at the same rate.

5. Bake

Place the cookies on your prepared baking sheet, leaving a little space between each one. They won’t spread much, so no need to worry about crowding. Bake for 12-15 minutes, or until the edges are just starting to turn golden. Don’t overbake—shortbread should be pale and buttery, not brown.

Cooling and Storing

6. Cool Completely

This part is tough, but resist the urge to eat them straight out of the oven. Let the cookies cool on the baking sheet for about 10 minutes before transferring them to a wire rack. They’ll firm up as they cool, giving you that perfect crumbly texture.

7. Store Properly

Once cooled, store the cookies in an airtight container. They’ll last for about a week at room temperature (if you don’t finish them sooner) or up to a month in the freezer. Just be sure to layer parchment paper between them if you’re stacking to avoid sticking.

Tips for Perfect Keto Pistachio Shortbread Cookies 

• Use quality almond flour. Super-fine almond flour makes a huge difference in texture. Coarse almond meal can leave the cookies gritty.
• Softened butter, not melted. If your butter is too soft or melted, the dough won’t hold together. Aim for butter that leaves a dent when pressed but isn’t shiny or runny.
• Don’t skip the chilling step. Chilling the dough firms up the butter and keeps the cookies from spreading too much. It’s worth the extra time.
• Customize the sweetness. Everyone’s sweet tooth is different. Taste your dough (since there’s no raw egg) and adjust the erythritol if needed before baking.

What to Serve with These Cookies?

These cookies pair beautifully with a cup of coffee or tea. If you’re feeling fancy, dip half of each cookie in melted sugar-free dark chocolate for an extra treat. They also work great crumbled over keto-friendly yogurt or as a snack on their own when you’re craving something sweet.

Common Substitutions and Variations

• No almond flour? Substitute with hazelnut or pecan flour for a different flavor, but keep in mind the texture might change slightly.
• Dairy-free? Use coconut oil instead of butter, but chill the dough a bit longer since coconut oil melts faster.
• Nut-free? Swap pistachios for sunflower seeds and almond flour for a keto-friendly nut-free baking mix.
