Ingredients
For these delightful cookies, gather the following ingredients:

- 1 large egg (room temperature)

How to Make vegan marshmallows Crispy Cookies (Costco Copycat)
Step 1: Preheat the Oven
Preheat your oven to 350°F. Line a baking sheet with parchment paper to prevent sticking.
Step 2: Brown the Butter
To begin, melt the ½ cup of butter in a medium saucepan over medium heat. Continue cooking past boiling and stirring frequently until it turns golden brown and emits a nutty aroma. Be watchful, as it can burn quickly. Once browned, transfer it to a bowl and let it cool in the fridge or freezer for about 10 minutes.
Step 3: Mix Sugars and Egg
In a medium mixing bowl, combine the cooled brown butter with both sugars. Add the egg and vanilla extract. Mix on low speed until smooth, which should take about 30 seconds.
Step 4: Combine Dry Ingredients
Gradually add in salt, baking soda, and flour while mixing carefully to avoid overmixing.
Step 5: Fold in Rice Krispies and Marshmallows
Gently fold in the rice krispies followed by the mini vegan marshmallows until they are evenly distributed throughout the dough.
Step 6: Scoop Dough onto Baking Sheet
Using a cookie scoop (about 3 tablespoons), portion out large balls of dough onto the prepared baking sheet. Leave enough space between each ball as they will spread during baking.
Step 7: Bake Your Cookies
Bake in your preheated oven for about 10–13 minutes or until the edges are lightly golden brown. Be careful not to overbake; you want to keep that chewy center! Once baked, sprinkle lightly with flaked salt before allowing them to cool on a wire rack.
