4-Ingredient Buttery Gluten Free Shortbread Cookies

Some of the best things are the simplest, and these gluten free shortbread cookies are proof. They take just 4 main ingredients and taste so buttery and crisp you would never guess they skip the wheat.

A batch comes together in minutes with a handful of pantry staples. Slice them thick or thin and bake until the edges turn pale gold.

Why This Shortbread Works

The ingredient list is short, but every one pulls its weight. Real butter gives the cookies that rich, melt-away texture, and a straight gluten free flour blend keeps them light without any graininess.

I make these when I want cookies that hold their shape and taste better than anything from a box. The dough is forgiving, stays good in the fridge for days, and the cookies stay crisp in a tin.

Ingredients

• 1/2 cup unsalted butter, softened: the foundation of shortbread; use a good quality block butter, not a tub spread
• 1/4 cup granulated sugar: keeps the cookies crisp and lightly sweet
• 1 tsp vanilla extract: rounds out the buttery flavor
• 1 cup gluten-free all-purpose flour blend: a 1-to-1 blend with xanthan gum works best (like Bob’s Red Mill)
• 1/4 tsp fine sea salt: a pinch, optional but recommended (not counted in the 4 main ingredients)

Variations / Substitutions

• Add citrus zest: rub the zest of a lemon or orange into the sugar before creaming with the butter for a bright note
• Dip in chocolate: let the cooled cookies cool completely, then dip half of each in melted dark or semi-sweet chocolate
• Make them nutty: fold 2 tbsp finely chopped pecans or almonds into the dough for a little crunch
• Dairy-free swap: a solid plant-based butter stick works in place of dairy butter; the cookies will spread a touch more
• No blend handy?: you can make your own mix with 3/4 cup rice flour plus 1/4 cup tapioca starch and a pinch of xanthan gum

How to Make Gluten Free Shortbread Cookies

Step 1: Cream the Butter and Sugar

In a large bowl, beat the 1/2 cup softened butter and 1/4 cup granulated sugar with an electric mixer on medium speed until the mixture looks pale and fluffy, about 2 minutes. Beat in the 1 tsp vanilla extract just until combined. Stop and scrape down the sides of the bowl once so everything blends evenly.

Step 2: Shape the Dough into a Log

Add the 1 cup gluten free flour blend and the 1/4 tsp salt. Mix on low speed just until the dough comes together and no dry streaks remain. Turn the dough out onto a piece of plastic wrap, shape it into a log about 6 inches long and 2 inches wide, and wrap it tightly. Chill until firm, at least 30 minutes or up to 3 days.

Step 3: Slice the Chilled Dough

Preheat the oven to 325°F (165°C) and line a baking sheet with parchment paper. Unwrap the chilled log and use a sharp knife to slice it into rounds about 1/4 to 1/2 inch thick. Aim for even slices so they bake at the same rate.

Step 4: Bake the Cookies

Arrange the slices on the prepared sheet about 1 inch apart. Bake for 12 to 15 minutes, rotating the pan halfway through, until the edges are just starting to turn a pale golden brown and the tops look set. The cookies will still feel a little soft when they come out, and that is exactly what you want.

Step 5: Cool and Dust with Sugar

Let the cookies rest on the hot baking sheet for 5 minutes, then transfer them to a wire rack to cool completely. While they are still warm, dust the tops with a little extra granulated sugar if you like a sparkly finish. Once cool, they will be crisp and buttery through the center.

Tips for the Best Gluten Free Shortbread

• Soften the butter on the counter for about an hour, not in the microwave. You want it to give when pressed with a finger, not look greasy or melted.
• Do not overwork the dough once the flour goes in, or the cookies can turn tough. Mix just until it comes together.
• If the log feels soft while you are slicing, pop it back in the fridge for 10 minutes. Clean slices make prettier cookies.
• The cookies firm up as they cool, so pull them from the oven when the edges are just blushing gold and the centers look dry.

Bake times depend on how thick you slice the cookies:

Storing and Freezing

Keep the cookies in an airtight container at room temperature for up to 5 days. A small piece of parchment between layers stops them from sticking. They also freeze well for up to 2 months; thaw them on the counter for an hour before serving.

What To Serve With Gluten Free Shortbread Cookies

A pan of these cookies and a pot of hot Earl Grey tea is a quiet afternoon win. For dessert, crumble them over vanilla ice cream with a spoonful of salted caramel, or set them out next to a bowl of fresh berries and softly whipped cream. The buttery crunch holds up against something cool and juicy.

Frequently Asked Questions

Which gluten free flour blend works best?

A 1-to-1 blend that includes xanthan gum, such as Bob’s Red Mill, gives the most shortbread-like texture. Straight almond flour or coconut flour will not work the same way.

Can I use coconut oil instead of butter?

I wouldn’t. Shortbread gets its signature texture from butter, and swapping in coconut oil will make the cookies spread more and lose that classic crisp edge.

Why did my cookies spread into puddles?

Warm butter or a short chill time is usually the culprit. Make sure the dough log is fully firm before slicing, and pop the baking sheet in the fridge for 10 minutes before baking if your kitchen is warm.

Can I add chocolate chips to the dough?

You can, but the cookies may not hold their tidy round shape as well. Mini chips stirred in gently work better than large chunks.

Ingredients Method Notes

Ingredients

  

• 1/2 cup unsalted butter, softened
• 1/4 cup granulated sugar
• 1 tsp vanilla extract
• 1 cup gluten-free all-purpose flour blend (1-to-1 with xanthan gum)
• 1/4 tsp fine sea salt

Method

 

1. Beat the butter and sugar with a mixer on medium speed until light and fluffy, about 2 minutes. Beat in the vanilla.
2. Mix in the flour and salt on low speed just until a dough forms. Shape into a 6-inch log, wrap in plastic, and chill at least 30 minutes.
3. Preheat the oven to 325°F (165°C) and line a baking sheet with parchment. Slice the chilled dough into even rounds 1/4 to 1/2 inch thick.
4. Place slices on the sheet 1 inch apart. Bake 12 to 15 minutes, rotating halfway, until edges are pale gold and tops look set.
5. Cool on the sheet 5 minutes, then move to a wire rack. Dust with extra sugar while warm if desired. Cool completely.

Notes

Chilling time is extra and varies; the dough can chill up to 3 days before slicing. If you like a slightly softer cookie, pull them from the oven when the centers still look just a little underdone; they will set as they cool.
