Smart Pantry Swaps & Ingredient Notes
The heart of these cookies is a simple chocolate dough made with everyday staples: butter, sugars, eggs, flour, cocoa powder, and a touch of baking soda. The cocoa powder gives that deep, slightly bitter chocolate flavor that pairs beautifully with the sweet marshmallow surprise. I like to use mini marshmallows because they’re easier to wrap, but you can also use large ones cut in half.
For substitutions, feel free to swap the butter for vegan butter and use a flax egg for a plant-based version. If you’re out of mini marshmallows, try using a chocolate-covered marshmallow or even a spoonful of marshmallow fluff (just freeze it first to make it easier to handle). And if you love extra chocolate, toss in some chocolate chips—they add a nice texture contrast to the gooey center.
🛒 Quick Substitution Cheat Sheet
- Room-Temperature Rule: Let cold dairy, eggs, or proteins sit out for 15 minutes before cooking for even heat transfer.
- Herb Swap: Use 1 teaspoon dried herbs for every 1 tablespoon of fresh chopped herbs called for.
- Seasoning Balance: Finish with a tiny squeeze of fresh lemon juice or flaky sea salt right before serving to brighten rich flavors.
