Choosing the Right Ingredients for the Best Bars

Getting your ingredients right makes a big difference in flavor and texture.

Vegan Marshmallows: Traditional marshmallows contain gelatin, so, as health experts note, it’s important to opt for brands like Trader Joe’s or Dandies that use plant-based alternatives. These melt and toast wonderfully, mimicking the classic marshmallow experience. They’re also the key to other marshmallow-based desserts like our vegan Rice Krispie treats.

Chocolate Chips: Look for dairy-free chocolate chips, such as Guittard semi-sweet or Trader Joe’s brand. Double-check the ingredient list to avoid milk fat or butter oil.

Butter Substitute: Melted vegan butter adds richness to the crust. If you’re feeling adventurous, you can even learn how to make vegan butter at home, but store-bought works perfectly. You can also substitute coconut oil if preferred.

Non-Dairy Milk: Almond, soy, or coconut milk all work well to bind the dough.

Flour: All-purpose flour works best, but you can swap with gluten-free blends if needed. Remember, the consistency might vary slightly.

Step-by-Step Instructions to Make Perfect Vegan S’mores Cookie Bars

Follow these simple steps to create your bars:

1. Prep your pan: Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper for easy removal.
2. Mix the wet ingredients: In a large bowl, whisk together melted vegan butter, brown sugar, pure vanilla extract, and almond milk until smooth.
3. Add dry ingredients: Stir in all-purpose flour, baking powder, and salt with a wooden spoon until just combined. Avoid overmixing to keep the bars tender.
4. Form the base layer: Use your hands (dampened slightly if sticky) to press two-thirds of the dough evenly into the bottom of your prepared pan.
5. Add toppings: Sprinkle 1 cup of vegan chocolate chips evenly over the crust, followed by a layer of vegan marshmallows.
6. Top it off: Crumble the remaining cookie dough over the marshmallows, then scatter the remaining chocolate chips on top.
7. Bake and toast: Bake for 25 minutes until the cookie crust is golden. Optional: Use the broiler for 1–2 minutes to achieve extra toasty marshmallows—but watch closely to prevent burning.
8. Cool before slicing: Let the bars cool in the pan for about 10 minutes to set before cutting into squares. Enjoy warm or at room temperature!

Tips for the Best S’mores Bars

Getting perfect bars can be easy with a few handy tips, many of which are standard practice among professional bakers:

• Don’t overmix: Stir until ingredients just come together to avoid tough bars.
• Par-bake the crust if needed: If you prefer a firmer base or are doubling the recipe in a larger pan, bake the crust alone for 8-10 minutes before layering the chocolate and marshmallows.
• Marshmallow toasting: Use the broiler briefly for a golden top, but keep watch to avoid burning.
• Wet your hands: The dough can be sticky; wetting your hands helps with pressing it evenly.
• Customize sweetness: You can reduce brown sugar slightly if you prefer a less sweet bar.

Ingredient Substitutions and Variations

Feel free to experiment based on your pantry or dietary needs:

• Coconut Oil: Swap vegan butter for melted coconut oil for a subtle coconut flavor.
• Gluten-Free: Use a 1:1 gluten-free baking flour mix to make these bars gluten-free.
• Alternative Sweeteners: Coconut sugar can substitute brown sugar, but may change the flavor slightly.
• Add Graham Cracker Crust: For a traditional s’mores vibe, add a graham cracker crust layer beneath the cookie base.
• Nut Butters: Swirl peanut or almond butter into the dough for added richness and flavor depth.

Troubleshooting Common Baking Issues

Sometimes your bars might not turn out perfectly. Here’s how to fix common problems:

• Gooey or undercooked crust: Make sure to press dough firmly and consider par-baking the crust before adding toppings.
• Burnt marshmallows: Use the broiler with extreme caution. Keep the oven door ajar and watch every 30 seconds.
• Dough too sticky to handle: Chill for 15-20 minutes or wet your hands before pressing.
• Lack of rise or dense texture: Ensure your baking powder is fresh and gently mix dry ingredients.

Following these troubleshooting tips can help you confidently bake perfect bars every time.

How to Store, Freeze, and Reheat Your Vegan S’mores Bars

To enjoy these bars over time:

• Storage: Keep bars in an airtight container at room temperature for up to 3 days.
• Refrigeration: Store in the fridge for up to one week if you want them firmer.
• Freezing: Wrap bars tightly in plastic wrap and foil, freeze for up to 3 months. Thaw at room temperature for 20-30 minutes before serving.
• Reheating: Warm in a microwave for 15-20 seconds to revive gooeyness, or use a low oven heat for 5-7 minutes.
