sliced vegan s'mores cookie bars

If you love making s’mores, then I just know that you’re going to love these irresistibly decadent vegan s’mores bars (yes, even if you’re not vegan!).

These cookie s’mores bars are THE s’mores bars to make. Similar to my s’mores cookies, these s’mores cookie bars are incredible easy to make with a no chill cookie dough and easy assembly.

We have a layer of crisp vegan graham crackers layered with gooey and chewy chocolate chip cookie base LOADED with molten vegan milk chocolate, a thick layer of vegan marshmallow fluff and more cookie dough!!

It’s honestly even better than you think it’ll be, I swear.

Minus the eggs, dairy, and gelatin, of course 😉 Yep, you won’t even be able to detect that these gooey and easy s’mores bars are entirely vegan, dairy free, and eggless (and easily gluten free too!).

As with all of my recipes, the full written instructions with ingredient measurements is found down below in the recipe card. However, we’ll go over the basics here with visuals.

You’ll start by making the chocolate chip cookie layer. This part of the recipe is adapted from my vegan chocolate chip cookies. You’ll start by whisking together the wet ingredients, then folding in the dry ingredients. Finally, fold in the chocolate chips.

Then start to assemble the bars. Layer with graham crackers. Then press half the cookie dough into your prepared 9×9″ pan, followed by a layer of vegan marshmallow fluff and the remainder of the cookie dough.. Then set this aside, and quickly prepare the marshmallow fluff.

You can finish with more graham crackers and mini marshmallows on top!

Pro tip: Press the top cookie dough down on the sides to create almost like an encasement around the inside layers. This prevents the marshmallow from seeping out of the sides.

Bake for 30 minutes, then cool for 20 (so that the marshmallow sets!). Slice and serve!

Description

These deliciously molten and gooey vegan s’mores cookie bars are layered with a cinnamon graham crackers, one bowl chocolate chip cookie dough, vegan milk chocolate, gooey vegan marshmallow fluff!!! They’re like a campfire in bar form, without the eggs, dairy, and gelatin!

Ingredients

Scale

Cookie Layer (adapted from my Simple Vegan Chocolate Chip Cookies):

  • 10 tbsp (144 g) melted vegan butter
  • 1 heaping tbsp dairy-free yogurt
  • 1 cup (200 g) granulated sugar
  • 1/2 cups (100 g) packed light brown sugar
  • 1 tbsp vanilla extract
  • 1/4 tsp baking soda
  • 1/2 tsp sea salt
  • 2 cups + 1 tsp (264 g) all-purpose flour OR gluten-free 1:1 baking flour*
  • 3 tbsp dairy-free milk, optional
  • 2 cups vegan chocolate chips and/or chopped dark chocolate
  • 1 cup mini vegan marshmallows
  • 1/2 cup crushed vegan graham crackers

S’mores cookie bar layers:

  • 8–10 vegan graham crackers (homemade or store-bought)
  • 1 6-ounce jar vegan marshmallow fluff (I use Dandy’s)

Instructions

  1. Prep: Preheat the oven to 350. Grease and line an 9×9″ baking dish with parchment paper. Set aside.
  2. Make the cookie dough base: In a large bowl, whisk together the vegan butter, brown sugar, sugar, dairy free yogurt, and vanilla extract until combined.  Then add in the dry ingredients (flour, baking soda,  and sea salt), and use a rubber spatula to mix the flour into the wet ingredients until there are almost no more dry streaks. Add in the chopped chocolate and chocolate chips, along with the crushed graham crackers and mini marshmallows. Fold again until the chocolate chips are just mixed into the dough.
  3. Assemble: Layer a single layer of graham crackers on the bottom of the pan. I use about 8 with the Once Again brand. Then press half of the dough on top of the graham crackers to form the bottom cookie layer. Spread the jar of vegan marshmallow fluff on top. The finish by pressing the remaining cookie dough layer on top, and pressing down the cookie dough along the edges to encase the s’mores layers inside. This prevents the marshmallow from seeping out. Press crumbled graham crackers and more mini marshmallows on top if desired.
  4. Bake: Place into the oven to bake for 30-32 minutes, or until lightly golden on top.
  5. Cool: Remove the cookie bars from the oven and let the s’mores bars rest for 20 minutes. Then use a clean kitchen knife to slice and serve. Wipe the knife in between each slice for a cleaner cut. 
  6. Serve and enjoy! Store any leftover in an airtight container for up to 5 days at room temperature or 3 months in the fridge. Heat the bars in the microwave for 15-20 seconds to melt the marshmallow again.
