Brown Butter Chocolate Chip Sourdough Cookies (Gluten-Free)

Gluten Free Brown Butter Chocolate Chip Cookies are a delightful variation on the classic gluten-free chocolate chip cookie. These cookies are made with brown butter for a deep, nutty flavor and include gluten-free sourdough discard for a gentle tang and added moisture.

After many tests during my gluten-free sourdough journey, I developed this sourdough-discard chocolate chip cookie recipe. The combination of brown butter and discard results in cookies with crisp edges and soft, gooey centers. They may be my favorite gluten-free chocolate chip cookies yet.

Recipe Ingredient Notes

Gluten Free Flour: This recipe works well with common 1:1 gluten-free flour blends. Different blends can affect spread and texture: some blends yield slightly more compact cookies while others spread more.

Sourdough Discard: Sourdough discard is the portion of a starter removed during feeding. You can use fed or unfed discard; room-temperature discard is convenient. The discard should come from a starter that is well established, and the discard itself should not be overly old or extremely sour. The discard contributes flavor and moisture that pair beautifully with brown butter.

Egg Yolks: This recipe uses egg yolks only. For consistency, weigh them if possible.

Milk Powder: Adding milk powder (whole or non-fat dairy milk powder) enhances the brown-butter flavor and adds richness. This is optional but recommended if you enjoy pronounced brown-butter notes. Non-dairy milk powders are not a suitable substitute here.

Chocolate: I like a mix of chopped dark chocolate and semi-sweet chips for texture and flavor contrast. Top each cookie with extra chips before baking for attractive melty puddles; larger baking wafers work well for big puddles.

Why Add Sourdough Discard to Chocolate Chip Cookies?

Using gluten-free sourdough discard in cookie dough is a practical way to use excess starter while improving flavor and texture. The discard adds a mild tang that balances the sweetness, plus moisture that helps the cookies stay soft and chewy. Though discard isn’t a primary leavening agent, residual fermentation can contribute a touch of lift and a lighter crumb. For best flavor development, refrigerate the dough for at least 24 hours when possible.

How to Make Brown Butter

Brown butter (beurre noisette) is made by cooking butter past its melting point until the milk solids caramelize and turn golden-brown, producing a rich, nutty aroma and flavor. Use a heavy-bottomed, light-colored pan so you can watch the color change, and stir frequently. Browned butter can burn quickly once the solids begin to brown, so remove it from heat when it reaches a medium amber color and transfer it to a heatproof bowl to preserve the brown bits. Let it cool for 15–20 minutes so it is still liquid but not hot before using in the recipe.

Gluten Free Brown Butter Chocolate Chip Cookie Dough

Making the dough is straightforward; browning the butter is the most technical part. This recipe relies on both brown butter and sourdough discard to achieve the intended flavor and texture, so both should be used.

Step 1: Whisk together the gluten-free all-purpose flour, baking soda, and salt in a small bowl and set aside.

Step 2: Add light brown sugar, granulated sugar, and vanilla to the cooled but still liquid brown butter.

Step 3: Cream on medium speed for 2–3 minutes until pale and fluffy, pausing halfway to scrape the bowl.

Step 4: Add room-temperature egg yolks and mix 30 seconds.

Step 5: Add the sourdough discard and mix on medium for 30 seconds, then scrape down the sides completely so no streaks of butter remain.

Step 6: Mix in the dry ingredients on low speed until a dough forms.

Step 7: Fold in chopped dark chocolate and semi-sweet chips briefly on low speed so you don’t overwork the dough. Transfer the dough to an airtight container and chill in the refrigerator. Chilling is mandatory: for best results chill at least 4 hours, ideally 12–48 hours so the flour hydrates and flavors meld.

Baking Instructions

If the dough was chilled for several hours, let it sit at room temperature for about 10 minutes to make scooping easier.

Step 1: Preheat the oven to 350°F (175°C). Line baking sheets with parchment paper.

Step 2: Use a large cookie scoop to portion dough. This recipe yields about 12 cookies depending on scoop size and how much dough was sampled.

Step 3: Place six dough balls per sheet, leaving space to spread. Top each with extra chocolate and gently press down to encourage even spreading.

Step 4: Bake at 350°F for 8 minutes, rotate the tray, then bake an additional 7–8 minutes until lightly golden and just set. Baking time varies by oven and cookie size.

Step 5: Remove from the oven. If you prefer a perfect round shape, use a slightly larger round cutter to nudge the cookies while warm. Sprinkle with flaky sea salt if desired and cool on the baking sheet 5–10 minutes before transferring to a rack. Repeat with remaining dough.

Storage & Freezing

Store fully cooled baked cookies in an airtight container at room temperature for up to 3 days. For longer storage, freeze baked cookies and thaw at room temperature or in the fridge.

To freeze unbaked dough: Portion dough into cookie-sized balls, top with extra chocolate, and place on a parchment-lined tray so they don’t touch. Freeze 1–2 hours until firm, then transfer to a resealable bag or airtight container and label. Bake from frozen, adding a few extra minutes to the bake time as needed.
