Crush graham crackers in a blender or crush by hand.

Melt butter in the microwave in a microwave safe bowl.

Mix butter with crushed graham crackers and press into a 9 x 9 baking dish.

Pour sweetened condensed milk over the graham cracker crust.

Put Reese's Peanut Butter Cups on top of sweetened condensed milk.

Bake at 350° for 15 minutes.

Remove from oven and carefully press pretzels into the dessert.

Return to oven and continue baking for 25-28 minutes. Sweetened condensed milk will turn a caramel color.

Let cool completely before cutting (you can refrigerate it to cool it-but serve at room temperature).

When dessert has cooled, melt chocolate chips and shortening in the microwave-watch closely and stir every 10-15 seconds.

Drizzle chocolate over dessert. Cut and serve. Enjoy!

Remember, if you refrigerate this dessert, you will want to serve it at room temperature so let it sit on the counter to return to room temperature.
