prep and Cook Time
- readiness: 20 minutes
- Baking: 28 minutes
- Cooling Time: 15 minutes
Yield
Approximately 16 tasty bars
Difficulty Level
Easy to Medium – perfect for bakers of all skill levels
Ingredients
- 1 cup unsalted butter,melted
- 1 cup light brown sugar,packed
- ½ cup granulated sugar
- 2 large eggs,at room temperature
- 2 tsp pure vanilla extract
- 1½ cups all-purpose flour,sifted
- 1 tsp baking powder
- ½ tsp fine sea salt
- 1¾ cups mini marshmallows
- 1¾ cups semisweet chocolate chips
- 1 cup graham cracker crumbs (freshly crushed for optimal texture)
Instructions
- Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking pan or line it with parchment paper for easy removal.
- Combine wet ingredients: In a large bowl, whisk together melted butter, light brown sugar, and granulated sugar until smooth and glossy. Add eggs one at a time,stirring well after each addition,then fold in vanilla extract.
- Mix dry ingredients: In a separate bowl, sift together the all-purpose flour, baking powder, and sea salt. Gradually fold the dry mixture into the wet, stirring just until no dry streaks remain. Be careful not to overmix to keep the bars tender.
- Layer your base: Press half of the batter evenly into the prepared pan, creating a firm but soft base. This layer anchors your gooey masterpiece.
- Sprinkle the magic: Evenly distribute the graham cracker crumbs,mini marshmallows,and chocolate chips over the base layer. This layering is critical to infuse every bite with bursts of gooeyness and crunch.
- Top it off: Gently drop spoonfuls of the remaining batter over the marshmallow layer. Use a spatula to carefully smooth it out; some marshmallows may peek thru for an irresistible look.
- Bake to perfection: Place the pan in the oven and bake for 25-28 minutes. Watch closely-the edges should be golden brown, while the center remains soft and just set. Avoid overbaking to prevent losing that luscious chew.
- Cool wisely: Let bars cool in the pan for 10 minutes,then transfer to a wire rack for at least another 15 minutes before slicing. This allows the gooey center to firm up slightly for neat squares that still melt in your mouth.
Tips for Success
- Use high-quality chocolate: Opt for semisweet or bittersweet chips for richer, more complex flavor that balances the sweetness of marshmallows and graham crumbs.
- marshmallow variety matters: Mini marshmallows melt quickly but retain shape; for an ooey-gooey texture, try mixing in a few larger marshmallow pieces.
- Layering technique: Pressing each layer gently but firmly keeps the distinct textures intact, preventing ingredients from sinking or blending too much!
- Make-ahead tips: Bars can be made a day in advance and stored in an airtight container at room temperature to enhance flavor melding.
- Substitution ideas: For a gluten-free twist,replace all-purpose flour with a 1:1 gluten-free baking blend and use gluten-free graham crackers.
- For extra crunch: Add chopped toasted nuts like pecans or walnuts between the layers for delightful texture contrast.
Serving Suggestions
Slice your bars into generous squares and serve slightly warm to emphasize maximum gooeyness. Pair with a cold glass of milk or a scoop of vanilla bean ice cream for an indulgent treat that dances on the palate.
Garnish with a sprinkle of crushed graham crackers or a drizzle of melted chocolate for that extra visual and flavor appeal. Perfect for dessert tables, potlucks, or cozy night-ins, these bars are best enjoyed with company to share smiles and stories.
