Instructions
Melt the butter in a small sauce pan over medium heat. Add the sugar to the butter and stir until dissolved, about 1 minute. Remove from heat.
Whisk 1/4 of the butter-sugar mixture to the beaten eggs little by little until completely incorporated. This will temper the eggs to keep them from scrambling. Slowly whisk the egg mixture into the butter-sugar mixture in the saucepan, and place it on the stove top over medium heat once again. Whisk until the mixture is thickened and bubbly, about 1-2 minutes. Remove from heat, and stir in the peanut butter and vanilla until incorporated. Set aside the mixture to cool for 30 minutes.
Once cooled, pour the butter-sugar mixture into a large bowl. Add the graham cracker crumbs and stir to combine, followed by the marshmallows, then the chocolate chips and peanut butter chips.
Press the mixture evenly into a parchment lined 8x8 square baking dish and refrigerate until firm, about 30 minutes to 1 hour. Remove from the pan and cut into squares. Enjoy!
Notes
Store leftover bars in an air tight container in the refrigerator for 3-5 days.
