INGREDIENTS
- 1/2 cup unsalted butter (1 stick)
1 large egg
1 cup light brown sugar
1 tablespoon vanilla extract
3/4 cup all-purpose flour
5 full-size graham crackers
1 heaping cup mini marshmallows
1 cup semi-sweet chocolate chips
DIRECTIONS
1. Preheat oven to 350F. Line an 8-by-8-inch baking pan with aluminum foil, spray with cooking spray; set aside.
2. In a large, microwave-safe bowl melt the butter, about 1 minute on high power.
3. Wait momentarily before adding the egg so you do not scramble it. Add the egg, brown sugar, vanilla, and whisk until smooth.
4. Add the flour and stir until just combined, do not overmix.
5. Add the graham crackers and any crumbs on cutting board, marshmallows, chocolate chips and fold to incorporate.
6. Turn batter out into prepared pan, smoothing the top lightly with a spatula.
7. Bake for about 20 to 22 minutes, or until bars have firmed up in the center and edges will be set. Some marshmallows may have developed a hint of golden color. Allow bars to cool in pan for at least 30 minutes before slicing and serving. Bars will keep airtight at room temperature for up to 1 week, or in the freezer for up to 6 months.
