Description

Deliciously soft and chewy Rocky Road Cookies packed with semisweet chocolate chips, mini marshmallows, and sliced almonds for a perfect sweet and nutty treat.


Ingredients

Scale

Cookie Dough

  • 1/2 cup butter
  • 3/4 cup brown sugar packed
  • 1/4 cup granulated sugar
  • 1 teaspoon vanilla extract
  • 1 large egg
  • 1 1/3 cups all-purpose flour
  • 1/3 cup unsweetened cocoa powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt

Add-ins

  • 1/2 cup semisweet chocolate chips
  • 1 cup halved mini marshmallows
  • 1/4 cup sliced almonds


Instructions

  1. Preheat Oven: Preheat the oven to 350 F. Line 2 baking sheets with parchment paper or silicone baking mats to prevent sticking and make cleanup easy.
  2. Melt Butter: Microwave the butter in a large, microwave-safe bowl for about 40 seconds until mostly melted. Whisk thoroughly until completely melted and smooth.
  3. Mix Sugars: Add brown sugar and granulated sugar to the melted butter and mix until well combined and creamy.
  4. Add Vanilla and Egg: Stir in vanilla extract and the large egg until fully incorporated into the sugar-butter mixture for a smooth batter.
  5. Add Dry Ingredients: Sift or stir the flour before measuring to avoid packing. Add the all-purpose flour, unsweetened cocoa powder, baking soda, and salt into the wet mixture. Mix the dough just until combined, resulting in a soft and slightly sticky dough but not overly sticky.
  6. Fold in Add-ins: Gently stir in semisweet chocolate chips, halved mini marshmallows, and sliced almonds ensuring even distribution throughout the dough.
  7. Scoop Dough: Using a medium cookie scoop or about 1.5 tablespoons of dough, scoop and place cookies approximately 2 inches apart on the prepared baking sheets to allow room for spreading.
  8. Bake Cookies: Bake in the preheated oven for 10 minutes or until the cookies are set. They should appear puffy and slightly underbaked in the center upon removal.
  9. Cool and Serve: Remove the baking sheets from the oven and allow cookies to cool for a few minutes on the sheet before transferring them to a wire rack to cool completely.

Notes

  • Use salted butter for richer flavor or unsalted butter if preferred.
  • For the best results, weigh flour using a kitchen scale; if measuring by cups, sift or stir the flour before measuring to prevent dry, crumbly cookies.
  • Do not overmix the dough to keep cookies soft and chewy.
  • Spacing cookies 2 inches apart ensures even baking and prevents merging.
  • Cookies appear soft and underbaked in the center but will firm up as they cool.
