How to Make vegan marshmallows Crispy Cookies (Costco Copycat)
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper to prevent sticking.
Step 2: Brown the Butter
Begin by melting ½ cup salted butter in a medium saucepan over medium heat.
1. Continue cooking until it turns golden brown and emits a nutty aroma.
2. Stir constantly to avoid burning.
3. Once browned, pour into a bowl and cool in the fridge or freezer for about 10 minutes.
Step 3: Mix Sugars and Wet Ingredients
In a mixing bowl, combine the cooled brown butter with both sugars:
1. Stir until well blended.
2. Add in the large egg and vanilla, mixing on low until smooth (about 30 seconds).
Step 4: Combine Dry Ingredients
Gradually mix in the baking soda, salt, and all-purpose flour.
1. Be careful not to over mix; just combine until there are no dry spots.
Step 5: Fold in Add-Ins
Gently fold in the rice krispie cereal, followed by the mini vegan marshmallows. Ensure everything is evenly distributed throughout the dough.
Step 6: Scoop Cookies onto Baking Sheet
Using a cookie scoop (approximately 3 tablespoons), portion out dough onto the prepared baking sheet:
1. Place 4-5 cookies per sheet to allow room for spreading.
Step 7: Bake
Bake your cookies for about 10-13 minutes:
