Ingredients
- 1 cup crushed graham crackers
- 2 tbsp light butter, melted
- ¾ cup packed brown sugar
- ¼ cup light butter, softened
- 1 large egg
- 1 tsp vanilla extract
- ¾ cup all-purpose flour
- ¼ tsp baking powder
- Pinch of salt
- ⅓ cup mini semi-sweet chocolate chips
- ½ cup mini marshmallows
Instructions
1. Prepare the Pan and Crust
Preheat oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment.
In a small bowl, mix graham cracker crumbs and melted butter. Press mixture firmly into the bottom of the pan to form a crust.
2. Make the Blondie Batter
In a medium bowl, cream softened butter and brown sugar together. Beat in the egg and vanilla until smooth.
In another bowl, whisk together flour, baking powder, and salt. Add dry ingredients to wet and mix until just combined.
3. Assemble the Bars
Spread blondie batter evenly over the graham crust. Sprinkle chocolate chips and marshmallows on top, pressing them lightly into the batter.
4. Bake and Cool
Bake for 18–20 minutes, or until edges are set and center is slightly soft (it will firm as it cools). Cool completely in the pan before slicing into 12 bars.
