how to make Marshmallow Crispy Cookies

Ingredients :

  • ½ cup salted butter
  • ¾ cup brown sugar
  • ½ cup granulated sugar
  • 1 large egg (room temperature)
  • 1 teaspoon vanilla (this is a good time to use vanilla paste if you have it)
  • ½ tsp baking soda
  • ¾ tsp salt
  • 1 cup all-purpose flour
  • 1½ cups rice krispie cereal
  • ⅔ cup mini marshmallows
  • flaked salt for topping

Directions :

  1. Preheat your oven to 350°F. Line a baking sheet with parchment paper.
  2. Start by browning the butter. Melt the ½ cup of butter in a medium saucepan. Keep cooking it over medium heat past the boiling point. Stir it carefully until it turns a nice golden brown and gives off a nutty smell. Watch it closely to avoid burning.
  3. Once the butter is browned, pour it into a bowl and let it cool in the fridge or freezer for about 10 minutes.
  4. In a medium mixing bowl, mix the brown butter with both sugars. Add the egg and vanilla, then mix on low until smooth, about 30 seconds.
  5. Gradually mix in the salt, baking soda, and flour, being careful not to over mix.
  6. Fold in the Rice Krispies and mini marshmallows gently.
  7. Scoop the dough into large balls. A 3-tablespoon cookie scoop works well for this. Place 4-5 cookies on the baking sheet as they will spread thin.
  8. Bake the cookies for 10-13 minutes. Look for a light golden brown around the edges. Be careful not to over bake, or the center will lose its chewiness. Sprinkle with flaked salt.

tips to make Marshmallow Crispy Cookies

  • Make sure your butter is browned but not burnt. The nutty flavor is key!
  • Use room temperature eggs to help the dough mix evenly.
  • Don’t over mix after adding the flour; this will keep your cookies soft.
  • For extra chewiness, add more mini marshmallows.
  • Experiment with different chocolate chips or nuts for fun variations.

variation

If you want to change things up, consider adding chocolate chips or swapping the Rice Krispies for another cereal. You could also sprinkle some mini chocolate chips on top before baking for an added treat.

FAQs

1. Can I use unsalted butter instead of salted?
Yes, but if you do, add a pinch of salt to the recipe to balance the flavors.

2. How can I prevent my cookies from spreading too much?
Make sure you chill the dough before baking if you find them spreading too thin in the oven.

3. Can I use regular marshmallows instead of mini marshmallows?
Yes, you can chop regular marshmallows into smaller pieces if you prefer. Just be mindful of how they are mixed in to keep the cookie structure.
