In this post, we’ll uncover the secrets to perfecting your very own batch of these delightful cookies.

Ingredients List

To get started, gather the following ingredients:

• 3 cups crispy rice cereal
• 2 cups mini marshmallows (you can use regular ones for a more gooey texture)
• 1 cup granulated sugar
• ½ cup unsalted butter
• 1 tsp vanilla extract
• 1/4 tsp salt
• Optional: 1/2 cup chocolate chips for a delicious twist

Ingredient Substitutions:

• Swap white sugar for coconut sugar for a deeper flavor.
• Use vegan butter or coconut oil as a dairy-free alternative.
• For a gluten-free version, ensure you use gluten-free crispy rice cereal.

Timing

Preparing these cookies only takes about 30 minutes: 10 minutes for prep and 20 minutes for cooking. This is 30% faster than the average cookie recipes, allowing you to satisfy your sweet cravings in a flash!

Step-by-Step Instructions

Step 1: Melt the Butter

In a medium-sized saucepan, melt the butter over low heat. This step should take about 2-3 minutes. The slow melting helps in achieving a perfectly creamy base.

Step 2: Mix Sugar and Marshmallows

Once melted, add the granulated sugar, salt, and vanilla extract. Stir until well combined before adding the mini marshmallows. Keep the heat low and mix until the marshmallows are mostly melted—about 3-5 minutes.

Step 3: Combine with Cereal

Remove the saucepan from heat. Add the crispy rice cereal to the melted marshmallow mixture and stir well until evenly coated. The texture should be sticky yet manageable.

Step 4: Shape Your Cookies

Using a spatula or your hands (lightly greased), scoop out portions of the mixture and shape them into cookie-like forms on a parchment-lined baking sheet. Don’t worry about making them perfect; the rustic look adds to their charm!

Step 5: Cool and Enjoy

Let the cookies cool at room temperature for about 10 minutes. Once set, they are ready to be devoured!
