Preheat your oven to 350 degrees F (176 C) and line two baking sheets with parchment paper. Set aside.
To a medium mixing bowl, add the flaxseed meal and water. Set aside for 5 minutes to let gel (this is your “flax egg”). Next, add the coconut sugar and vegan butter and beat with an electric mixer (or a whisk and some elbow grease) until light and fluffy, about 1 minute.
Add in the all-purpose flour (or gluten-free flour blend), baking powder, and sea salt and mix on medium-low until fully incorporated. Fold in the chocolate chips and mini marshmallows.
Use a ~1 ½ Tbsp cookie scoop (we like this one) to scoop out your cookies and place them 2 inches apart on your baking sheets. Top each cookie with 1-2 extra mini marshmallows and gently press them into the dough (they get slightly brown in the oven, just like the marshmallow in the perfect s’more!).
Bake on the center rack for 10-12 minutes, until the edges are golden brown and the marshmallows are lightly browned. Let cool on the baking sheet for 5-10 minutes before transferring to a wire rack to cool further. Enjoy warm or cooled.
Store leftovers in an airtight container for up to 3-4 days at room temperature. You can store scooped dough for up to 1 month in the freezer.
Notes
*Coconut sugar gives these cookies a graham flavor, but brown sugar would also work, with a slightly different result. *We slightly preferred the texture of the cookies with our 1:1 BEST GF Blend (vs. our DIY GF Blend), but both work! If using our DIY Blend or another gluten-free flour blend, we suggest using 1 ⅓ cups of flour because they tend to be less absorbent. *Adapted from our Vegan Gluten-Free Chocolate Chip Cookies. *Nutrition information is a rough estimate calculated with all-purpose flour and Dandies marshmallows.
