Dive into pure decadence with these oversized Rocky Road cookies featuring chocolate-packed dough, melty marshmallows, and crunchy cashews. Every jumbo treat delivers soft, chewy middles with slightly crispy edges—a dream come true for anyone who takes their cookies seriously.
I've made so many cookie batches in my life, but this version really knocks it out of the park with its texture and deep flavor. The first time I baked them, they vanished within a few hours and everyone wanted to know my secret. I found out that mixing cake flour with regular flour creates that hard-to-achieve balance between tender and chewy.
Key Ingredients and Smart Shopping Advice
- Cold Butter: Keep it chilled and cut into small cubes for the right cookie structure.
- Cocoa Powder: Go for Dutch-processed to get richer color and better taste.
- Cake Flour: It has less protein, which makes your cookies softer.
- Mini Marshmallows: Big ones will just melt away and leave holes in your cookies.
- Cashews: Give them a quick toast before chopping to bring out their nutty flavor.
Step-by-Step Baking Guide
- Step 1: Nail Your Butter Technique
- Use butter right from the fridge. Beat it until it's super fluffy and turns light yellow. Don't rush this part. Remember to scrape down your bowl often so everything mixes evenly.
- Step 2: Handle Dry Stuff With Care
- Run your cocoa through a sifter to break up clumps. Mix everything with a light touch to keep the air in your butter mixture. Stop once you don't see any flour streaks. Use upward folding motions when you stir.
- Step 3: Add Mix-ins Like a Pro
- Save some goodies to stick on top of each cookie. Make sure your chunks are spread evenly through the dough. Don't dawdle or your dough will warm up too much. Fold gently so you don't smash the marshmallows.

These treats always take me back to family camping trips where we'd huddle around the fire making rocky road s'mores. Now I whip up these cookies for family get-togethers to bring back those good old days while making fresh memories too.
While working on this recipe, I learned just how much temperature matters in baking. The combo of cold butter and hot ovens creates that amazing texture that has everyone reaching for seconds.
Baking these cookies has turned into our Saturday ritual. There's something magical about the smell of chocolate and toasted nuts that always brings the whole family running to the kitchen.

Crafting these cookies feels like making little bundles of happiness. The way the flavors and textures come together makes them extra special, and their generous size means they're perfect for sharing (though you might want to hide a few for yourself!).
