How to Make vegan marshmallows Crispy Cookies (Costco Copycat)
Step 1: Preheat Your Oven
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. This ensures that your cookies bake evenly and don’t stick to the pan.
Step 2: Brown the Butter
In a medium saucepan, melt your ½ cup salted butter. Cook it over medium heat until it turns golden brown and emits a nutty aroma. This step is crucial as browning the butter adds depth of flavor to your cookies. Keep an eye on it; it can go from perfect to burnt quickly! Once browned, pour it into a bowl and let it cool in the fridge or freezer for about 10 minutes.
Step 3: Mix Together Sugars and Egg
In another medium mixing bowl, combine the cooled brown butter with both sugars—brown sugar and granulated sugar. Add in the room temperature egg and vanilla extract. Mix on low speed until everything is smooth and well combined, about 30 seconds.
Step 4: Combine Dry Ingredients
Now it’s time to add our dry ingredients! Slowly mix in the salt, baking soda, and flour while being careful not to over-mix. Over-mixing can lead to tough cookies instead of soft ones.
Step 5: Fold in Rice Krispies and Marshmallows
Gently fold in the rice krispie cereal followed by those delightful mini vegan marshmallows. This step is where you see that lovely contrast between crispy cereal and chewy marshmallows coming together!
Step 6: Scoop the Dough
Using a tablespoon cookie scoop (around 3 tablespoons), scoop generous amounts of dough onto your prepared baking sheet. Remember to leave space between each cookie; they will spread as they bake!
Step 7: Bake
Pop those beauties into your preheated oven for about 10-13 minutes. Look for them to turn lightly golden around the edges while keeping their chewiness in the center. Be careful not to over-bake! Once done, sprinkle flaked salt on top for that extra touch.
And there you have it! A delicious batch of vegan marshmallows Crispy Cookies (Costco Copycat) that are sure to impress everyone around you. Enjoy every bite!
Pro Tips for Making vegan marshmallows Crispy Cookies (Costco Copycat)
Baking is all about precision and love, so here are some tips to ensure your cookies come out perfectly every time!
- Use room temperature ingredients: This helps the butter and sugar cream together more efficiently, resulting in a fluffier cookie dough.
- Watch the butter closely while browning: The difference between perfectly browned butter and burnt butter is just seconds. Stir consistently and remove it from heat once it reaches a golden brown color with a nutty aroma.
- Don’t overmix the dough: Overmixing can lead to tough cookies. Mix just until the flour is incorporated to keep your cookies tender.
- Scoop uniformly: Using a cookie scoop ensures that all your cookies are roughly the same size, which means they will bake evenly.
- Experiment with toppings: A sprinkle of flaked salt right after baking adds a delightful contrast to the sweetness and enhances the flavor of the cookies.
