Chocolate Peanut Butter Butterscotch Squares

I've had versions of this square before and always wanted to figure out how to make them as I love them! My sister Rebekah gave me a recipe for them last year but we tried them and they didn't quite turn out right. Then lucky for me she went to a cookie exchange just before Christmas and got this recipe...and they're absolutely perfect! Thanks Rhonda Dubeau (the girl she got the recipe from)!

I have no idea what they're actually called so I'm calling them:

Chocolate Peanut Butter Butterscotch Squares

1 pkg milk chocolate chips
1 pkg butterscotch chips
1 cup peanut butter
1/2 cup of shortening
1 small bag of mini marshmallows (fruit marshmallows preferred)

Place the first 4 ingredients in a double broiler and stir until completely smooth. Let cool for 5 minutes. Line the bottom of a 9x13 inch pan with waxed paper. Cover the bottom of the prepared pan with some of the chocolate peanut butter mixture then add the bag of marshmallows on top. Then cover with the remaining chocolate peanut butter mixture. Place in the freezer for 30 minutes or until firm, remove and cut in to bite sized squares.

Enjoy!

* Note: Chris suggested to add Chow Mein Noodles next time which I thoughtwould be a good addition so I tried it today and made half the pan with the noodles and half without. I think I like the squares better without the noodles, but Chris and a few others I've asked like the squares better with the noodles. I think it just depends if you like a little crunch in your chocolate. (The top row of squares in the picture has the noodles in them and the bottom row doesn't.)

*Note: If you're allergic to peanut butter, use an additional bag of chocolate or butterscotch chips. Flavour will of course change, but they should still be great;)
