Ingredients
Scale
- 1/2 cup salted butter (softened)
- 3/4 cup brown sugar (lightly packed)
- 1 large egg (room temperature)
- 1 teaspoon vanilla extract
- 1 1/2 cups all-purpose flour (spooned and leveled)
- 1/4 cup cocoa powder
- 3/4 teaspoon baking soda
- 1/4 teaspoon baking powder
- 1/2 teaspoon salt
- 1/2 cup chocolate chips (plus extra for topping)
- 48–60 mini marshmallows (or 6 full-size marshmallows)
Instructions
- Cream butter and sugar: Use a bowl and a hand mixer or stand mixer to beat the softened butter and brown sugar until light and fluffy, about 2–3 minutes.
- Add egg and vanilla: Beat in the egg and vanilla until fully combined and smooth.
- Mix dry ingredients: Whisk together flour, cocoa powder, baking soda, baking powder, and salt, then add to the wet mixture in batches until just combined.
- Fold in chips and marshmallows: Gently fold in 1/2 cup chocolate chips and most of the mini marshmallows, reserving a few to press on top of each cookie dough ball.
- Form cookie portions and prepare pressure cooker: Scoop dough into tablespoon-sized balls and press a few extra chocolate chips and marshmallows on top. Place a metal trivet in the pressure cooker, add 1 cup of water, and set a foil-lined, oven-safe dish or silicone mold on the trivet; arrange cookies with space between.
- Cook and cool: Cover and cook on high pressure for 6–8 minutes depending on size, then quick-release. Let cookies cool in the dish for a few minutes before transferring to a rack to finish setting.
Notes
Use room-temperature eggs and softened butter for a smooth dough. Store cooled cookies in an airtight container for up to 3 days.
