These are truly gooey cookies. Melty chocolate chips and stretchy vegan marshmallows turn an already decadent double chocolate cookie into something extra special. The marshmallows add a delightful chew and a toasty note reminiscent of campfire s’mores—without the mess.

The cookie dough comes together in a single bowl, producing a thick batter that yields soft, brownie-like cookies loaded with chocolate and pockets of marshmallow. They’re ideal for summer gatherings, campfires, or any time you want a rich, comforting treat.

Are marshmallows vegan?

Most conventional marshmallows contain gelatin and are not vegan. Fortunately, there are excellent vegan options on the market. Brands like Dandies or certain store-brand vegan marshmallows perform beautifully in baking and taste great when toasted.

How to make these cookies from scratch

Start by melting the vegan butter and whisking it with the granulated sugar in a large bowl. Add vanilla, ground flaxseed, and soy or other plant-based milk, then combine well.

Sift the dry ingredients—flour, Dutch-processed cocoa powder, baking soda, and salt—directly over the wet mixture and stir until a thick dough forms. Fold in vegan chocolate chips or chunks and the mini vegan marshmallows, reserving a few to press on top before baking.

Scoop about two tablespoons of dough per cookie, roll into balls, and flatten slightly on a parchment-lined baking sheet; they will spread a bit while baking. Optionally press extra chocolate chips or marshmallows on top for presentation.

Bake until the edges are set but the centers remain soft—about 10 minutes. Allow cookies to rest on the baking sheet for five minutes to firm up, then transfer to a cooling rack to cool completely.

Do the marshmallows melt while baking?

Vegan mini marshmallows soften and become gooey in the oven but generally keep their shape rather than liquefying. They brown lightly on the surface, giving that toasted-marshmallow flavor. For an extra-toasty finish, lightly brown the marshmallow tops with a kitchen blow torch after baking.

Tips and substitutions

  • Vegan butter: You can substitute refined coconut oil for the vegan butter if preferred.
  • Non-dairy milk: Use soy, almond, cashew, oat, or any plant-based milk you like.
  • Graham crackers: Fold in crushed vegan graham crackers to emphasize the s’mores flavor.
  • Rocky road variation: Add chopped almonds or other nuts for extra texture.
  • Gluten free: Swap the all-purpose flour for a gluten-free all-purpose blend of equal measure.
  • Storage & freezing: Store cookies at room temperature in an airtight container for several days, or freeze in a sealed bag for up to three months.
