These Brown Butter S’mores Cookies are the kind of thing people ask you about at parties. Each one starts with a digestive biscuit base, a square of chocolate, a whole marshmallow, and a thick disc of nutty brown butter cookie dough draped right over the top. A little more effort than a standard drop cookie, but the gooey, chocolatey result speaks entirely for itself.
Why you will love this recipe?
These cookies have everything going for them. Brown butter brings a deep, toffee-like richness you simply cannot get any other way, the marshmallow inside goes perfectly gooey in the oven, and that crispy digestive biscuit base ties the whole S’mores experience together in one bite. They are made in one bowl, freeze ahead beautifully, and deliver a thick, bakery-style result every single time. If you have been looking for the best stuffed S’mores cookies to make at home, your search ends here.
Expert Tips for Best Results!
- Use the bowl trick straight out of the oven – Place a round bowl or cookie cutter over each hot cookie and swirl gently to push the edges into a perfect circle before they set.
- Start checking at 9 minutes – The cookies should look slightly underdone when you pull them out. They will continue to set on the tray as they cool and that is exactly where the gooey centre comes from.
- Use a light-colored saucepan – In a dark pan it is hard to see when the milk solids turn golden and you risk burning the butter before you notice.
- Use digestive biscuits over graham crackers – They are less sweet, have a more neutral flavour that lets the cookie shine, and their round shape gives you a cleaner, more uniform base than graham crackers can.
- Gram measurements are strongly recommended – A kitchen scale takes the guesswork out of baking and gives you consistent results every time. If you do not have one, use the spoon-and-level method for flour. Spoon it into the measuring cup and level off the top with a straight edge. Never scoop directly from the bag or you will end up with too much flour and a dry, dense cookie.
How to make Brown Butter Chocolate Chip S’mores Cookies?
Step 1: Brown the Butter
Cook the unsalted butter in a light colored saucepan over medium heat, stirring frequently. First, the butter will foam, then settle, and finally develop golden brown milk solids at the bottom. Once it smells nutty and turns amber in color, immediately pour it into a heat safe bowl. The browned butter should weigh about 92–95 g. If needed, top it up with a splash of water or a little melted butter. Let it cool completely to room temperature.
Step 2: Make the Cookie Dough
Once the browned butter has cooled, whisk it together with the brown sugar and granulated sugar until thick and well combined. Add the cold egg and vanilla extract, then whisk again until smooth and glossy.
Step 3: Add the Dry Ingredients
Add the flour, instant coffee powder, corn starch, baking soda, and baking powder to the wet mixture. Using a spatula, gently fold until slight streaks of flour remain. Then add the chocolate chips and fold just until combined. Avoid overmixing to keep the cookies soft and tender.
Step 4: Prepare the S’mores Base
Line a baking tray with parchment paper. Arrange the digestive biscuits on the tray, then place one square of chocolate on top of each biscuit followed by a large marshmallow to create the classic S’mores filling.
Step 5: Assemble the Cookies
Take about 50–55 g of cookie dough per cookie and flatten it into a disc. Carefully drape the dough over the marshmallow and chocolate stack, allowing slight peeks of marshmallow to show through the sides for a bakery style finish.
Step 6: Freeze the Cookies
Place the assembled cookies in the freezer for 1–2 hours. This step is important because it helps prevent excessive spreading and creates thick cookies with gooey centres.
Step 7: Bake Until Perfectly Gooey
Preheat the oven to 175°C (350°F). Arrange the frozen cookies on a lined baking tray, leaving at least 3 inches between each cookie. Bake for 9–12 minutes until the edges look set while the centres remain slightly soft and shiny.
Step 7: Cool & Enjoy
Allow the cookies to cool on the baking tray for a few minutes after baking. They will continue to firm up as they rest. Serve warm to enjoy the irresistible combination of brown butter cookie dough, melted chocolate, gooey marshmallow, and crunchy biscuit layers.
Frequently Asked Questions
Can I make these ahead of time?
Yes. Assemble the cookies and keep them frozen for up to one week. Bake straight from frozen whenever you are ready, no thawing needed.
Can I refrigerate instead of freeze?
Refrigerating is not cold enough to get the same result. The freeze is what locks the shape and prevents the cookies from spreading too thin during baking.
Why is my dough too soft to shape?
Brown butter dough is naturally softer than regular cookie dough. If it feels too loose, refrigerate it for 20 to 30 minutes before shaping and it will firm right up.
How should I store these cookies?
Store fully cooled cookies in an airtight container at room temperature for up to 3 days. They stay soft and the marshmallow keeps its gooey texture without drying out.
Can I freeze baked cookies?
Yes. Once completely cooled, place them in an airtight freezer bag or container and freeze for up to 2 months. Thaw at room temperature for about 30 minutes or warm them in the oven at 150°C for 5 to 8 minutes to bring them back to life.
