🤎 Why You’ll Love This Recipe

• Fast shortcut: This recipe uses boxed brownie mix to create a fudgy, bakery-style cookie with minimal effort.
• Classic Rocky Road flavor: Each bite combines chocolate, marshmallow, and almonds for a nostalgic, crowd-pleasing treat.

🍫 Ingredients

(See the recipe card below for exact measurements.)

• Boxed brownie mix – the base gives a fudgy, dense cookie texture.
• Butter – use softened butter for richer flavor and better texture than oil.
• Eggs – large eggs help bind the dough.
• Mini marshmallows – small marshmallows distribute evenly; you can quarter larger ones if needed.
• Sliced almonds – use sliced rather than whole so each bite has a light almond crunch.
• Semi-sweet chocolate chips – balance sweetness and keep the chocolate flavor pronounced.

Additions & Substitutions

• For a lighter, airier cookie, try using boxed chocolate cake mix instead of brownie mix.
• If you prefer sweeter cookies, swap milk chocolate chips for semi-sweet.

🍪 How to Make Rocky Road Cookies

Step 1: Make the brownie cookie base

In a large bowl, use a hand mixer to blend the boxed brownie mix with softened butter and eggs until a thick dough forms.

Step 2: Fold in the add-ins

Gently fold in the mini marshmallows, sliced almonds, and chocolate chips. The dough will be thick—fold carefully to keep the add-ins intact. Chill the dough in the refrigerator for about an hour to firm up.

Step 3: Roll and bake

Roll the chilled dough into 1.5″ balls using your hands. Place them on a baking sheet lined with parchment or a silicone mat. Press a few extra marshmallows on top of each cookie for a gooey finish.

Bake in a 350°F oven for 8–10 minutes, until the edges set but the centers remain soft. Remove from the oven and cool on a wire rack.

🫙 Leftovers & Storage

Store cookies at room temperature in an airtight container for best texture. They stay fresh for about 5–6 days.

Can I freeze Rocky Road Cookies?

Yes. To freeze before baking, roll dough into balls, freeze on a sheet until firm, then transfer to a freezer bag for up to 6 months. When ready to bake, place frozen balls on a sheet and bake at 350°F for about 15–17 minutes. To freeze baked cookies, let them cool, then store in a freezer-safe bag for up to 6 months; thaw at room temperature.

💡 Tips & Tricks

• Use a hand mixer to form the brownie cookie dough—it’s thick and much easier to mix with power assistance.
• Fold add-ins by hand so marshmallows and chips stay intact.
• Chill the dough—refrigeration prevents spreading so the cookies remain fudgy and thick.
• Avoid overbaking; remove cookies when edges start to set to preserve a soft center.
