Main Ingredients
- 1 1/2 cups graham crackers, crushed into crumbs
- 1 cup all-purpose flour
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup unsalted butter, softened
- 3/4 cup brown sugar, packed
- 1 teaspoon vanilla extract
- 1 cup semi-sweet or milk chocolate chips or chunks
- 1 cup mini marshmallows
- Prepare Your Baking Pan: Line a 9×13-inch baking pan with parchment paper or lightly grease it to prevent sticking and ensure easy removal of bars after baking.
- Mix the Dry Ingredients: In a large bowl, combine the crushed graham crackers, flour, baking soda, and salt; mix thoroughly to evenly distribute the ingredients.
- Cream Butter and Sugar: In a separate bowl, beat the softened butter and brown sugar together until light and fluffy to create the chewy texture of the bars.
- Add Vanilla and Combine: Stir vanilla extract into the butter and sugar mixture. Gradually blend in the dry ingredients until just combined, being careful not to overwork the dough.
- Fold in Chocolate Chips and Marshmallows: Gently fold in chocolate chips and mini marshmallows to evenly distribute without melting or breaking them prematurely.
- Press Into the Pan and Bake: Transfer dough to the prepared pan and press evenly to the edges. Bake at 350°F (175°C) for 20–25 minutes until edges are golden but center is still slightly soft for gooeyness.
- Cool and Cut: Allow the bars to cool completely in the pan before cutting to help them hold their shape and prevent crumbling.
Notes
- Use fresh baking soda and vanilla extract for optimal flavor and rise.
- Do not overbake; remove when edges are set but centers remain soft for the perfect gooey texture.
- Press dough evenly in the pan to ensure uniform baking without thin or thick spots.
- Chill the dough if time permits to control spreading and deepen flavor.
- Add extra marshmallows on top during the last 5 minutes of baking for a toasted marshmallow crust.
- Variations: add nuts, make vegan with substitutions, double chocolate, drizzle salted caramel, or swirl peanut butter.
- Store bars in an airtight container at room temperature up to 3 days.
- Freeze individually wrapped bars up to 2 months; thaw at room temperature before serving.
- Reheat gently in microwave (10-15 seconds) or low oven to restore gooeyness.
