Everything You Need Lined Up
You gotta start with the basics for these pressure cooker chocolate marshmallow cookies. Here’s what you’ll be pulling together.
- ½ cup unsalted butter at room temp gets you that creamy base
- ⅓ cup light brown sugar packed good and tight for that caramel note
- ⅓ cup granulated sugar to balance sweetness just right
- 1 large egg, room temp so everything binds smoothly
- 1 ⅓ cups all-purpose flour acts as your cookie structure
- ½ teaspoon espresso powder to wake up the chocolate flavor
- ⅓ cup Dutch processed cocoa powder for that deep, rich chocolate vibe
- ½ teaspoon baking soda for gentle lift
- 1 teaspoon vanilla to bring everything together nicely
Don’t forget a pinch of salt too, about ½ teaspoon, to make those flavors jump. Then you want 1 cup chocolate chips for gooey spots of yum and ½ cup marshmallow fluff for all that sweet, fluffy surprise nestled in your cookie dough.

Walking Through Every Single Move
First off, preheat your oven to 350°F and line a baking sheet with parchment paper. You’re gonna use this for final baking after the pressure cooker step, trust me it works real good.
Next, grab a big bowl. Cream together your butter, brown sugar, and granulated sugar until it looks light and fluffy. You’ll feel the difference in the texture, kinda like you’re making cookie clouds.

Beat in the egg and vanilla. Make sure it’s mixed well so the dough won’t be lumpy or uneven.
In another bowl, whisk flour, cocoa powder, espresso powder, baking soda, and salt. Whisking helps break up clumps and spreads the espresso so you don’t bite into surprises.
Gradually add the dry stuff to the wet mixture, stirring just until combined. Overmixing can make your cookies tough and nobody wants that.
Now fold in the chocolate chips and marshmallow fluff gently so they distribute nice and even. Don’t squish the marshmallow fluff or it gets all sticky and weird.
Use a cookie scoop to portion dough onto your parchment-lined sheet. Space them about 2 inches apart so they can spread without crowding. Bake for 10 to 12 minutes or until edges look set but centers still feel soft.
Smart Shortcuts for Busy Days
Sometimes you just gotta get these cookies on the table fast. Here’s a couple ways to save time without skimping on yum.
- Make the dough up to a day ahead. Store it covered in the fridge so it’s ready when you are.
- Use pre-measured mixing packets for cocoa and espresso powder. Keeps your counters cleaner and your mixing faster.
- Freeze scooped dough balls on a tray, then toss into a sealed bag. Pop them straight on the tray when you wanna bake fresh cookies in minutes.
That First Bite Moment
You take that first bite and your teeth sink right into chewy softness. The chocolate part hits rich and deep but gentle enough that marshmallows melt just underneath your tongue.
Then you get bursts of sweetness from the gooey marshmallow fluff nestled inside. It’s like little clouds of sweet surprise waiting inside every bite.
The edges have this slight crisp that gives you contrast without being hard. You notice the espresso powder adding a tiny kick that makes chocolate pop. Totally yum and worth every minute you spent.

How to Store This for Later
Once you got these cookies made, you wanna keep them fresh so you can enjoy later. Here’s some storage tips that really work.
First, store cookies in an airtight container at room temp for up to 3 days. The softness stays pretty good and marshmallow fluff keeps that melty charm.
If you want them longer, toss cookies in a zip-top bag and freeze. When you pull them out, let thaw at room temperature for about 30 minutes. They come back super soft and gooey.
Reheating a cookie for just 10 seconds in the microwave can bring back those melty marshmallows and fresh-baked feels. Be careful not to overheat, or the marshmallow gets rubbery.
The FAQ Section You Actually Need
- Can I skip the espresso powder? Yeah, you can totally skip it. It just adds depth but cookies will still be tasty without it.
- Why use pressure cooker for cookies? It traps steam and heat quickly, kinda speeding up baking and keeping cookies super soft.
- What’s natural release in pressure cooking? It means you let the cooker cool on its own so pressure goes down slow. This helps keep delicate textures from getting dry or hard.
- Can I swap marshmallow fluff for mini marshmallows? You can try but fluff blends smoother. Mini marshmallows might melt unevenly or get sticky on top.
- Do I need a special sealing ring for this? A good tight sealing ring is always important to trap steam. Make sure yours fits well before you start.
- Can I add nuts to the dough? For sure! Chopped walnuts or pecans mix really well with chocolate and marshmallow goodness.
