Dive into pure heaven with these jumbo Rocky Road cookies that blend chocolatey dough, melty marshmallows, and crunchy cashews. Every massive cookie gives you the ideal mix of soft middles and slightly crunchy outer edges, making them a must-have for anyone who takes their cookie game seriously.
I've played around with tons of cookie recipes, but this one really knocks it out of the park with its amazing texture and deep flavor. The first time I made them, they vanished within minutes and everyone wanted to know my secret. I finally cracked the code when I found out mixing cake flour with regular flour creates that hard-to-get, soft-but-chewy bite.
Key Ingredients and Smart Picking Advice
- Chilled Butter: Has to be cold and diced - this builds the right cookie foundation.
- Cocoa Powder: Go for Dutch-processed for richer color and taste.
- Cake Flour: Its reduced protein makes cookies more delicate.
- Mini Marshmallows: Bigger ones will just melt away and leave empty spaces.
- Cashews: Give them a quick roast before chopping to bring out their flavor.
Step-by-Step Baking Guide
- Step 1: Nailing the Butter Mix
- Use butter right out of the fridge. Whip it until it's super fluffy - don't rush this part. Look for it to turn light yellow. Keep scraping the bowl regularly for even mixing.
- Step 2: Adding Dry Stuff Properly
- Run cocoa powder through a sifter to break up clumps. Mix with a light touch to keep air in your butter mixture. Stop right when you don't see streaks anymore. Use gentle upward motions while mixing.
- Step 3: Adding the Fun Stuff
- Save some goodies to push into the tops of cookies. Spread mix-ins throughout the dough evenly. Move fast to keep everything cool. Fold gently so you don't smash the marshmallows.

These cookies take me back to summer camp where we'd fix rocky road s'mores by the fire. Now I whip up these treats whenever the family gets together - they bring those old memories flooding back while we make fresh ones too.
Working on this recipe showed me why watching temperatures makes or breaks your baking. Cold butter mixed with a hot oven gives you that amazing texture that has everyone grabbing seconds.
Making these treats has turned into our Saturday ritual. When the smell of chocolate and toasted nuts fills up our kitchen, everyone suddenly appears asking when they'll be ready.

Baking these cookies feels like creating small bundles of happiness. The way all the textures and flavors come together makes them really outstanding, and their big size means they're great for sharing (though you might want to hide a few for yourself!).
Common Questions
- → Why use cold butter?
- Cold butter helps cookies stay plump and prevents them from flattening while baking.
- → Do I need cake flour?
- It gives a softer bite, but you can use just all-purpose flour if that's what you have.
- → Why such high baking temperature?
- Baking at 410°F creates a crisp exterior while keeping the middle wonderfully soft.
- → Can I make smaller cookies?
- Sure, just cut down the baking time and keep an eye on the marshmallows so they don't melt too much.
- → How do I store these?
- Keep them in a sealed container for up to 3 days, though they're at their best within the first 24 hours when marshmallows are fresh.
