Gather Your Ingredients
To kick things off, make sure you have everything you need within reach. Here's your checklist:
- 170 g all-purpose flour
- ¼ teaspoon baking powder
- ¼ teaspoon baking soda
- 1 teaspoon salt
- 115 g salted butter
- 150 g sugar (or brown sugar)
- 130 g sourdough starter
- 1 teaspoon vanilla extract
- ½ cup mini chocolate chips
- ¼ cup dark chocolate chunks
- ½ cup crushed graham crackers
- ½ cup mini marshmallows
Having these ingredients ready will streamline your baking experience.
Brown the Butter
Start by browning the butter in a small saucepan over medium heat. You’ll want it to bubble and turn a lovely dark golden color while stirring continuously. This step adds a rich, nutty flavor to your sourdough s’mores cookies. Once done, remove it from heat and let it cool to room temperature.
Mix the Dry Ingredients
In a separate bowl, combine the dry ingredients: flour, baking powder, baking soda, and salt. Take this moment to breathe in the aroma of fresh flour—baking is all about enjoying the process!
Combine Wet Ingredients
Once the butter has cooled but remains liquid, add it to a large bowl along with the sugar, sourdough starter, and vanilla extract. Whisk or mix using a hand mixer until everything blends smoothly. The kitchen will be buzzing with delicious scents!
Blend in Dry with Wet Ingredients
Now, take those lovely dry ingredients and gently fold them into the wet mixture. It’s like watching a masterpiece come together, so stir until they're fully combined—don’t be shy!
Incorporate Chocolate and Marshmallows
Here's where things get extra exciting! Add the chocolate chunks, chocolate chips, crushed graham crackers, and marshmallows. This is your chance to get creative and mix the textures together perfectly.
Chill the Dough
This might be the hardest part! Chill your dough in the fridge for at least 2 hours (or even overnight if you can wait). The chilling process is crucial—it helps improve both flavor and texture in your sourdough s’mores cookies.
Shape and Prepare for Baking
Preheat your oven to 375°F (190°C) and line a cookie sheet with parchment paper. Scoop about 2 tablespoons of chilled dough and roll them into balls, placing them a few inches apart on the sheet.
Bake and Flatten the Cookies
Once your cookies are in the oven, bake them for 12-15 minutes. Your cookies will puff up, with marshmallows possibly peeking out. No need to panic—this is all part of the magic. For the finishing touch, drop the parchment paper from about a foot above the counter to flatten them perfectly.
Cool and Enjoy!
After flattening, let your cookies cool on the sheet until they're completely set. As you take that first bite, you’ll discover just how delightful these sourdough s’mores cookies truly are!
With this step-by-step guide, you’re well on your way to baking something extraordinary. Enjoy the journey, and don’t forget to share your delicious results!

Gluten-Free Sourdough S’mores Cookies
If you're looking to cater to gluten-sensitive friends, don't fret! You can easily swap the all-purpose flour with a high-quality gluten-free blend.

This version will still deliver that delightful s’mores flavor, pairing perfectly with the chewy texture and warm notes from the brown butter.
