How to Make It

Get ready to bake these scrumptious bars with these easy steps.

Preheat

Preheat your oven to 350°F (175°C). This ensures even baking for chewy bars.

Cream

Cream together the softened unsalted butter, brown sugar, and granulated sugar until light and fluffy. This typically takes about 2-3 minutes.

Combine

Add the eggs and vanilla extract to the creamed mixture, mixing well until fully incorporated.

Mix Dry Ingredients

In a separate bowl, whisk together all-purpose flour, baking soda, and salt. Slowly add this dry mixture to the wet ingredients, stirring until just combined.

Fold In

Fold in the graham cracker crumbs, chocolate chips, and mini marshmallows. Be gentle to maintain a fluffy texture.

Bake

Spread the dough evenly into a greased 9×13-inch baking pan. Bake for 25-30 minutes, or until the edges are golden and the center is set.

Add Toppings

Sprinkle extra chocolate chips and marshmallows on top during the last 5 minutes of baking for that perfect finishing touch.

How to Store It

Fridge: store for up to 5 days in an airtight container.
Freezer: yes, wrap bars tightly to prevent freezer burn.
Reheat: microwave on low for 15-20 seconds until warm.

Tips for Best Results

• Let the bars cool completely before cutting to avoid crumbling.
• Use a non-stick spray to ensure easy removal from the pan.
