First, get out a large glass pan – 9×13 and give it a quick spray or line it with parchment paper. I prefer giving it a spray with pam.
Next, in a large pot melt the stick of butter and add in the 15 oz of marshmallows (about 50 large mallows). Stir with a spoon on medium to low heat until the mallows are melted. Then add in the vanilla. Oh, it’ll start to smell good at this point!
Once it’s all combined, add in the puffed rice one cup at a time. Stir until everything is well combined. Then, press into the greased pan and chill for 30 minutes. Be sure the top is evenly pressed down.
While the rice krispies are chilling, it’s time to make the cookie dough. Cream the butter and sugars together in a stand mixer. Once it’s light and fluffy add in the milk, vanilla, and the flour 1/2 a cup at a time. Mix well. Then, gently fold in the chocolate chips.
When the rice krispies are done chilling, top evenly with the cookie dough. I used a plastic sandwich bag to press the dough down evenly on top. Chill for another 30 minutes.
Once the chilling time is up, cut the 9×13 pan into quarters, then cut each smaller rectangle on an angle into 4 triangles each. Get out your sprinkles and melt the chocolate melts. Dip the triangles into the chocolate and top with sprinkles – set on parchment paper to set. That’s it! Then eat up or keep in an air tight container in the fridge.
