Kitchen Tools You’ll Need
This recipe doesn’t require fancy gadgets, just a few reliable kitchen basics to keep everything simple and stress-free.
- 9×13-inch baking pan
- Mixing bowls
- Measuring cups & spoons
- Wooden spoon or spatula
- Parchment paper
- Oven mitts
- Wire rack for cooling
Step-by-Step Beginner-Friendly Instructions
- Preheat & Prep: Preheat your oven to 350°F (175°C). Line a 9×13-inch pan with parchment paper for easy removal.
- Make the Crust: In a bowl, combine melted butter, graham cracker crumbs, brown sugar, and salt. Mix until evenly coated. Press firmly into the pan to form a crust.
- Add Chocolate & Marshmallows: Sprinkle the chocolate chips evenly over the crust. Then scatter mini marshmallows on top.
- Mix the Topping: In a separate bowl, whisk together flour, baking powder, egg, and vanilla extract until smooth. Drop spoonfuls of this dough mixture over the marshmallow layer.
- Bake to Golden Perfection: Bake for 25–28 minutes, or until the top is lightly golden and the edges are bubbling
- Cool & Slice: Allow bars to cool completely on a wire rack before cutting into squares. (They’ll firm up as they cool — patience pays off!)
Pro Tips
- Storage: Keep in an airtight container at room temperature for up to 4 days, or refrigerate for a chewier texture.
- Substitution Tip: Swap chocolate chips for dark chocolate chunks for a richer, grown-up flavor.
- Make Ahead: Bake and freeze up to 2 months — just thaw before serving.
- Serving Idea: Warm individual squares for 10 seconds in the microwave for that fresh-from-the-fire gooeyness!
