Ingredients

  • 10 oz vegan mini chocolate chips, divided
  • 2 tbsp olive oil (for melting chocolate)
  • 1/4 cup black 10/12 cocoa powder
  • 1 cup 1:1 gluten-free flour
  • 1/2 tsp salt
  • 4 large eggs, room temperature
  • 1/2 cup brown sugar
  • 1 cup granulated sugar
  • 2 tsp vanilla extract
  • 1/2 cup marshmallows

Instructions

  1. Preheat oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper and lightly coat with coconut oil.
  2. Melt 1 cup chocolate chips with olive oil over medium-low heat, stirring constantly. Set aside.
  3. Whisk cocoa powder, gluten-free flour, and salt together in a bowl.
  4. In a large bowl, mix eggs, brown sugar, granulated sugar, and vanilla. Stir in melted chocolate mixture.
  5. Fold dry ingredients into wet mixture until just combined. Stir in remaining chocolate chips.
  6. Spread batter evenly into prepared pan. Bake 34–40 minutes, until a toothpick comes out with moist crumbs.
  7. Cool in the pan for 1 hour.
  8. For spider web: Microwave marshmallows in 20-second bursts until soft and stretchy. Using food-safe gloves, stretch into thin strands and drape over brownies in a web design.
  9. Lift brownies from pan with parchment paper, slice, and serve.

Notes

  • Swap vegan chocolate chips and gluten-free flour for regular ingredients if preferred.
  • Add walnuts or pecans for crunch.
  • Enhance chocolate flavor with a pinch of instant coffee.
  • Decorate with plastic spiders or marshmallow ghosts for extra flair (remove inedible items before serving).
  • Use brownie mix for a quicker version.
