How to Make Sourdough S’mores Cookies with vegan marshmallows and Brown Butter
Step 1: Brown the Butter
Start by browning your butter in a small saucepan over medium heat. Stir it continuously until it becomes bubbly and turns a dark golden brown. This step is crucial because browning the butter enhances its flavor, giving your cookies that rich, nutty taste we all love!
Step 2: Cool the Butter
Once browned, remove the saucepan from heat and let the butter cool completely at room temperature. Cooling is important as it ensures that your dough doesn’t cook prematurely when mixed with other ingredients.
Step 3: Combine Dry Ingredients
In a separate bowl, whisk together your dry ingredients: flour, baking powder, baking soda, and salt. This helps evenly distribute the leavening agents so that every cookie rises perfectly.
Step 4: Mix Wet Ingredients
In a large mixing bowl, combine the cooled brown butter with sugar (or brown sugar), vanilla extract, and sourdough starter. Whisk until smooth. This mixture forms the base of your cookie dough—don’t skip this step!
Step 5: Add Dry Ingredients
Gently fold your dry mixture into the wet ingredients until just combined. Be careful not to overmix; we want those delicious little air pockets for chewy cookies!
Step 6: Incorporate Add-Ins
Now comes the fun part! Fold in mini chocolate chips, dark chocolate chunks, crushed graham crackers, and vegan marshmallows. Each ingredient adds its own character to these delightful cookies.
Step 7: Shape Your Cookies
Line a cookie sheet with parchment paper. Scoop about two tablespoons of chilled dough and shape each portion into balls before placing them on the sheet spaced about two to three inches apart. This spacing allows them to spread without sticking together during baking.
Step 8: Preheat Your Oven
Preheat your oven to 375°F (190°C) while letting your shaped dough rest on the counter for about 10 minutes—this helps improve texture!
Step 9: Bake Them Up
Bake for 12-15 minutes until they look puffy—don’t worry if some marshmallow peeks out! It’s all part of their charm.
Step 10: Flatten If Needed
Once out of the oven, gently lift the parchment paper off about a foot above the pan and drop it back down onto the counter. This simple trick flattens them perfectly! If necessary, use a butter knife to adjust their shape into perfect circles.
Step 11: Cool Down
Let your cookies sit on the cookie sheet until completely cool before transferring them to a wire rack. Patience is key here; they’ll be worth every second!

Pro Tips for Making Sourdough S’mores Cookies with vegan marshmallows and Brown Butter
Baking can be a delightful adventure, and these pro tips will help you achieve cookie perfection!
- Use Room Temperature Ingredients: Make sure your butter and sourdough starter are at room temperature. This helps to create a smooth batter, ensuring even mixing and better texture in the final cookies.
- Chill Your Dough: After mixing, refrigerate the cookie dough for at least 30 minutes. Chilling helps prevent the cookies from spreading too much while baking, resulting in thicker, chewier cookies.
- Rotate the Cookie Sheet: If you have an oven that doesn’t bake evenly, rotate your cookie sheet halfway through baking. This ensures all cookies get equal heat exposure for a perfectly baked treat.
- Watch Your Baking Time: Ovens can vary, so keep an eye on your cookies as they bake. You want them to be golden brown around the edges but still soft in the center; they’ll firm up as they cool!
- Customize Your Mix-Ins: Feel free to add or swap in other mix-ins like nuts or dried fruits! This not only adds variety but also personalizes your S’mores Cookies to your taste preferences.
