How to Make the Perfect Sourdough S’mores Cookies with Marshmallows and Brown Butter
Creating these cookies is an experience of its own, full of delightful aromas and eager anticipation. The steps are simple enough for any home cook.
Ingredients
- 170 g all-purpose flour
- 1/4 tsp baking powder
- 1/4 tsp baking soda
- 1 tsp salt
- 115 g salted butter
- 150 g sugar (or brown sugar)
- 130 g sourdough starter*
- 1 tsp vanilla extract
- 1/2 cup mini chocolate chips
- 1/4 cup dark chocolate chunks
- 1/2 cup crushed graham crackers
- 1/2 cup mini marshmallows (or cut-up big marshmallows)*
Step-by-Step Instructions
- Brown the butter in a small saucepan until bubbly and dark golden. Stir it continuously, careful to not burn it.
- Remove from heat and allow the butter to cool completely to room temperature.
- Combine the dry ingredients (flour, baking soda, baking powder, salt) in a separate bowl.
- Add the brown butter, sugar, vanilla extract, and sourdough starter to a large bowl. Combine with a whisk or hand mixer until even.
- Fold the combined dry ingredients into the wet ingredients. Stir until well combined.
- Add your chocolate chunks, chocolate chips, graham crackers, and marshmallows to the mixture.
- Line a cookie sheet with parchment paper. Scoop about 2 tablespoons of your chilled cookie dough and shape into balls.
- Preheat the oven to 375° (see notes on temperature) and place the cookie dough balls about two to three inches apart on the lined cookie sheet.
- Bake for 12-15 minutes. Remove from the oven. Your cookies may be puffy and some marshmallow may ooze out the sides, but it’s fine, do not panic; proceed to the next step.
- Lift the parchment paper off the pan about a foot above the pan and drop it onto the pan. This will flatten the cookies to the perfect texture. Because of the marshmallows, you may need to use a butter knife to fix the shape of the cookies to be more circular. Just pat the cookies around the side with a butter knife to make them a circular shape.
- Let them sit on the cookie sheet until they are completely cool.

For People with Diabetes: Sugar Substitutes
If you’re looking for alternatives to traditional sugar, consider using stevia, monk fruit, or allulose to maintain sweetness without the calories. However, avoid honey or maple syrup as alternatives, as they can impact blood sugar levels.

Pro Tips to Elevate Your Sourdough S’mores Cookies with Marshmallows and Brown Butter
- Chill the dough: If you have extra time, consider chilling your cookie dough. This will help control the spread and enhance the flavors.

Storing and Reheating Tips

Common Mistakes to Avoid
- Using cold butter: Ensure the butter is browned and cooled to enhance flavor and texture.
