Recipe Information
Ingredients
- 0.75 cup unsalted butter
- 1 cup brown sugar, packed
- 1 teaspoon vanilla extract
- 1.5 cups all-purpose flour
- 2 cups rolled oats
- 0.5 teaspoon baking soda
- 0.25 teaspoon salt
- 3 cups mini marshmallows
- 1 cup semi-sweet chocolate chips
Instructions
Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking pan.
In a large bowl, cream together the unsalted butter and brown sugar until light and fluffy.
Add the vanilla extract and mix well.
In a separate bowl, whisk together the all-purpose flour, rolled oats, baking soda, and salt.
Gradually add the dry ingredients to the wet ingredients and mix until fully combined to form a crumbly dough.
Press about two-thirds of the oatmeal mixture evenly into the prepared baking pan to form the bottom crust.
Bake the crust in the preheated oven for 10 minutes, then remove it from the oven.
Sprinkle the mini marshmallows evenly over the partially baked crust, followed by the semi-sweet chocolate chips.
Crumble the remaining oatmeal mixture over the top of the marshmallows and chocolate to form the top layer.
Bake for an additional 15 minutes, or until the top is golden brown and the marshmallows are melty and slightly toasted.
Remove the pan from the oven and allow it to cool completely on a wire rack.
Once cooled, cut into squares and serve. Store leftovers in an airtight container for up to 3 days.
